Description of the Invention: TECHNICAL FIELD OF THE INVENTION The present invention belongs to the glass industry and is applied to sheet glass used in the field of TFT-LCD film and electronics. [Prior Art] Today, the low-thickness thin-film glass used in the TFT_LCD screen and electronic fields is mainly manufactured by a "floating" process or by an "overflow" process of downward stretching. A thin-film glass manufacturing process called "floating method" (us 326688〇; US·3771985' EP 1739062; and US 2008/0223079) uses a molten tin bath on which the glass floats while the glass is cooled and pulled Stretch to form a solid sheet glass. In the "floating" method, the two surfaces of the molten glass are each in a different medium: a) the lower surface is in molten tin; and b) the upper surface is in a tin bath atmosphere. Thereby the heat exchange via each of the two glass surfaces during cooling is different. On the other hand, due to the expansion of the chemical component self-solubilized tin bath, there are contaminations on the surface of the four glass sheets. These problems have forced subsequent polishing processes to result in a sheet glass surface quality that is lower than that obtained using the "overflow pull-down" method.

insulated pipe (“(4)”), which performs the following functions simultaneously: a) Static distribution of glass flow rate in a flat stream of molten glass; b) glass cooling; C) two streams of the aforementioned molten glass are combined or merged to form a single stream of glass suitable for stretching. Figure i shows the molded body or "closed insulated pipe" (1)); molten glass from the melting furnace 161469.doc 201233644 The glass enters through the zone (12), and the zone (12) and the upper end zone of the molded body (π) The upper cut neck (13) is connected; the molded body has two side walls (14), and the molten glass overflows over the upper edge (15) of the two side walls (14) and the glass moves through the neck ( 13) and overflow edge (15) 'At the same time the cross section of the glass decreases at a constant flow rate per unit of length. Next, the molten glass flows in two streams (丨6) on the outside of the two side walls of the molded body (11) while it is cooled until reaching the apex (17) below the molded body (1), where two The strands join to form a single molten glass flake (18) that is stretched into a solid state. The two surfaces forming the flakes come from the interior of the molten glass matrix which has flowed down the neck and overflows its side walls without coming into contact with the solid surface. The patent (U.S. 3,338,696) is still the current state of the art implemented today, however, the "overflow pulldown" process still has some limitations, as shown in the patent (U_S. 7, 155, 935). The first shortcoming of the /blow-down method is the variation of the thickness of the glass flakes due to the complex distribution of the flow rate of the liquid glass overflowing along the sides of the molded body or the "closed insulated tube"; this distribution The phenomena inherent in the process are sensitive, such as: a) the change in the temperature distribution of the molten glass at the entrance of the "closed insulated tube", since each point of the input section follows its own path through the neck and always points to The same position of the formed sheet; ...the change in the flow rate of the glass from the melting furnace, because the flow rate of the glass overflowing on both sides of the "closed insulated tube" is not a linear function of the height of the glass on the overflow, and the flow rate and The instantaneous change in temperature causes a change in the thickness of the final sheet glass; c) the thermoplastic deformation of the "closed insulated tube" itself, which is due to the arrow caused by the bending in the body changing the overflow of the molten glass during the manufacturing operation. 201233644 . The thickness may be undesirably varied; d) the external environment of the upper neck region and the temperature of the overflow affect the distribution of the thickness of the glass in the final sheet; and e) Near the entrance area of the sheet has to flow around the periphery of the input section of the "closed-insulated pipes" and may have a lower quality of the glass. In order to overcome these listed deficiencies, several solutions have been proposed (w〇 2005/0268657, U.S. 2005/0268659; U.S. 2005/0183455; U.S. 2008/0202165; WO 2007/070825). The second disadvantage of the "overflow pull-down" method is that it is difficult to extend to a higher extraction rate and sheet size. This is due to the bending of the "closed insulated tube" due to thermal deformation and the stress on the sidewall caused by the molten glass hydraulic pressure. Neck size. In some cases, additional coupling is used to increase the width of the manufactured sheet glass (WO 2006/115792). The third drawback of the "overflow pull-down" method is that the glass remains below the area in each area of the #closed insulated tube due to glass devitrification. A solution has been proposed to avoid glass devitrification during molding, such as the duration of the temperature at the U.S. liquidus temperature, 2004/0093900 A1). Therefore, it is necessary to solve the defects of the aforementioned current manufacturing method in the field of thin >1 glass production. Disclosure of Invention Technical Problem The design of the method and related manufacturing apparatus of the present invention solves the deficiencies of the current method of manufacturing sheet glass. In the "floating" method, during the formation of the molten glass slab, the two surfaces are in the same medium having different heat exchange coefficients, thereby causing the thickness of the glass flake to change and requiring subsequent polishing. Process. In the "overflow pulldown" & 'single-molded body performs the static distribution of the molten glass in its upper end region and the cooling of the molten glass in the lower end region, thereby hindering the uniformity of the thickness of the final sheet, hindering the extension to the The size of the crucible and the duration of the production cycle are hindered by the devitrification of the glass. In order to improve the description of the present invention and to better understand the features thereof, a series of drawings are attached for the purpose of illustration and not limitation. DESCRIPTION OF THE INVENTION The method of the present invention for producing sheet glass comprises the following parts: a) a melting furnace for obtaining molten glass; a dosing group for producing a flat flow of molten glass having a uniform flow rate per unit width; a molding device for forming a continuous solid glass flake; and a cutting member for obtaining a glass article of a specific size. Instead of the static glass distribution used in the "overflow pull-down" method, the process of the present invention uses dynamic distribution to control and regulate the flow of glass from the dosing group in each glass drive module, and in this way, it is possible to adjust up to the dosing group. The number of glass drive modules is the thickness of the final sheet glass area. The adjustment of the flow rate through the glass of each drive module is accomplished by changing the rotational speed and/or the position of the rotary shaft of the rotating device belonging to the module to change the hydraulic height of the glass and the overflow through the drive module The molten glass flow of the road. The main function of the rotating device is to dose and adjust the mass flow of the glass in each drive module. In addition, the rotating device performs the function of mixing and homogenizing the molten glass physically and thermally, directly affecting the final quality of the article.

The number of the glass drive modules (27) is five in the two figures; The glass drive modules are separated from each other by side walls (28) and include rotating means (29) that perform the function of driving the molten glass, see Figures 5 and 6; these devices allow the molten glass to be associated with the input channel The hydraulic height is increased while regulating the flow rate through the overflow passages (36) belonging to each of the drive modules. The dividing wall (28) extends up to the dome of the overflow channel (36), and when the walls disappear, the molten glass of each drive module is joined into a single stream of molten glass flat (38) which flows and exits ( 37) Flow down to move to the next forming stage in the forming device. When a single dosing group is used, one of the two surfaces of the flat glass stream (38), i.e., the inner surface that has been in contact with the outlet (37), is modified by a cleaning device belonging to the forming device followed by a 'flat flow' (38). Divided into two streams of molten glass (48 and 49) flowing down on both sides of the shaped body (42) while the glass is cooled. The two streams of glass reach the apex below the shaped body and merge to form a continuous sheet of glass (50) which is stretched downward by means of a tractor to a particular article that is later divided into low-profile flat glass. In one embodiment of the method of the invention, the cleaning element comprises a rotating cylinder, Figures 7, 8 and 9; in another embodiment of the method of the invention, in the embodiment of the method of the invention, the cleaning element comprises a partial immersion in the glass The slab, Fig. 10, Fig. 12 and Fig. 12 show an overall view of two embodiments of the method of the invention using two different dosing groups (26 and 6), the dosing groups (26 and 60) having Each of the drive modules (27), the rotating device (29), the partition wall (28) and the overflow passage form two flat streams of molten glass (38 and 61). The two dosing sets (26 and 60) are partially supported by a structure (65) that is separate and spaced apart from the area (64) where the shaped and shaped bodies are integrated, see Figure 13. The glass flakes are stretched by the traction pro (51). Figure π shows a particular embodiment of the invention using two furnaces 'furnace crucible (21) and furnace crucible (66) for the development of two different glasses to obtain two different glass-glass crucibles and glass crucibles The formed glass flakes 'the two different glasses each occupy half of the thickness of the glass flakes from the apex (47) of the shaped body (64).

The present invention provides a process for producing a high quality thin flat glass comprising the steps of: 1) melting and refining a vitrifiable material using a melting furnace having an outlet passage to obtain a molten and refined glass substrate, the outlet passage A level adjuster is included to maintain a constant hydraulic height of the molten glass; 2) a dosing group comprising a plurality of glass drive modules is used, and a flat flow of molten glass having a uniform flow rate per unit width is dispensed and dosed to the glass. Each of the groups consists of at least one rotating device and a spillway, the glass of all the drive modules is finally joined to obtain the above flat flow of molten glass, and is transferred to the next stage via the outlet; 3) the use of the molded body and the traction member is included and optionally included The "cleaning" member is a molding device for modifying the bottom surface of the flat flow of the molten glass to convert the flat flow of the molten glass into a continuous solid glass sheet; and 4) dividing the continuous sheet by the cutting member to obtain a glass article of a predetermined size. Referring to the overview of Figures 3, 4, 11, and 12, the method of the present invention begins with refining molten glass in a molten grain (21) melted vitrifiable material (22) and in a refining vessel (23); Driven through the channel (24) to the dosing group (26) 'in the channel (24)' maintains a constant glass level h〇 using a level regulator (25) consisting of a side channel/outlet, Figure 5 and Figure 6. 161469.doc 201233644 is driven by a constant glass level H〇 through the molten glass of the channel (24) to the area where the dosing group (26) is active. The purpose of the dosing group (26) is to produce a flat flow of molten glass. (38), the width dimension is similar to the width of the sheet glass to be manufactured, and the flow rate per unit width is uniform. The dosing group collects the molten glass from the channel (24) and distributes it between several drive modules (27) placed in parallel (five in the illustrations of the figures); each glass drive module ( 27) A partition wall (28) constructed of an alloy of platinum and/or rhodium is separated from the adjacent module. The driving of the glass is performed by at least one rotating device (29) that adjusts and controls the hydraulic height H of the molten glass before passing through the overflow passage (36) belonging to the same driving module (27); Only the glass flow controlled and regulated by the rotating device (29) of the drive module flows through the overflow channels. Walls (28) that separate the drive modules from each other extend up to the dome of the overflow passage (36) and when the walls (28) disappear, all of the molten glass of each drive module is joined into a single strand of molten glass Flow (38), which flows and falls from the outlet (37) to move to the next forming stage. The dosing group (26) and the glass drive module (27) can be partially supported on its base structure (33) and/or Partially suspended from the top of the side wall (28). As shown in Figures 5 and 6, the dosing of the molten glass stream is performed by the rotating device (29) to "drive the molten glass from the input channel p4" and the rotating device (29) is performed with a constant glass height h〇 The function of the suction zone to the drive zone (35) having a glass height H, wherein the outlet overflow is (36). The space between the rotating means of each module and the side wall (28) in the direction of the glass flow (31) is larger than the space in the opposite direction (32); therefore, the flow of glass is pushed and driven in the manufacturing direction. The rotating device (29) is not limited to the design of 161469.doc -10· 201233644 shown in the figures, and various models can be used: & wheels, gears, flaps or eccentric elements, all within the scope or spirit of the invention . The rotating device is guided by at least one drive mechanism for controlling and adjusting the rotational speed and/or by a position mechanism for controlling and adjusting the position of the rotary device relative to each other and to the drive module to which it belongs. A particular embodiment of a drive module using two rotating devices, Figure 5, shows that each drive module (27) includes a base infrastructure (33) that extends to the overflow passage (36) and Ending at the outlet (37), the outlet (37) pours the glass in the form of a flat flow of molten glass (38) having a uniform flow rate per unit width to a shaped device positioned further down the upper outlet: each drive The module is also comprised of side walls (28) that separate the drive module from adjacent drive modules belonging to the same dosing group; such side walls (28) direct the molten glass to the overflow channel (36) ) The dome. The molten glass is collected from a suction region (34) having a hydraulic height Η0 and raised to a drive region (35) immediately adjacent to the overflow passage (36) at a hydraulic height 仏. The rotating shafts belonging to the two rotating devices (29) are separated by a magnitude De, and the portion immersed in the molten glass causes the blade (30) to have a shape, a rotational trajectory, a speed and a direction which determine the entire driving module. The volume of glass moves, the volume can be broken down into two separate volumes: a) antegrade volume (3 1) Vd, where the glass moves 'in the manufacturing direction' and b) the reflux volume (32) vR, where the glass is manufactured in reverse Move in the direction. The antegrade volume (31) is greater than the reflux volume (32) such that the glass is adjusted in a manner to vary the rotational speed of the rotating device (29) and/or the rotational axis of the rotating device (29) relative to the rotating device ( 29) The position DE, d丨 and d2 of the associated drive module (27) increase the hydraulic height ah = Η γ Η ο of the glass. 161469.doc 201233644 Figure 6 shows a diagram of a single movable component in each drive module. The hydraulic lift is performed by changing the rotational speed of the rotating device... and/or the rotating shaft of the rotating device relative to the side wall of the drive module (28) The eccentric position is achieved in ten days; as the positions of the rotating axes dl and A change, the two volumes antegrade and the return vR are simultaneously changed. The rotary device (29) of Figure 5 for flow regulation in the method of the present invention consists essentially of a rotary pump having two parallel shafts that collect molten glass having a glass height η0 from the input channel (24), And raising it to near the thick-walled overflow channel (36), the height of the glass has increased the south of the glass, maintaining a balance between the net flow rate of the driven glass and the glass flow rate through the overflow. Since the glass height Η〇 in the inlet zone (34) is kept constant, the glass height in the outlet zone (35) is Η! depending on the height 溢0 of the overflow channel dome (36); the flow of molten glass drives the QM to generate hydraulic pressure Height increase: ΔΗ = Ηι-Η〇(1) where: ΔΗ is the height increase produced by the rotating device; Hi is the glass height at the exit or drive area; and H〇 is the glass at the inlet or suction area Shangdu. In each rotation or rotation, the 'Fig. 5' rotating device causes a volume of antegrade glass (31) VD to be displaced along the sides of the module toward the drive region (35) and through the central region, the rotating devices A volume of return glass (32) Vr is displaced at a rotational speed w toward the suction region or inlet (34); the displacement of the volumes produces a flow Qm in each module:

(W) is a function of the rotational speed of the rotating device; Vd is the antegrade glass volume and VR is the reflow Glass volume; and Qm is the net flow rate of the glass in the drive module. The length and height Y of the overflow passage (36) hinders the movement of the glass driven by the rotating device (29), whereby the molten glass obtains an increase in the hydraulic height Δ11, which can be expressed as follows: ΔΗ = ΚΗ · w . μ . (VD-VR) (3) where: KH is a constant: ... is the rotational speed of the rotating device; and μ is the dynamic viscosity of the glass. For a given width Lm of the drive module, the forward theoretical volume VD of the driven glass and the reflow glass volume Vr depend on the distance between the rotational axes of the rotating device, which is based on the ratio that can be expressed as follows: (Vd-Vr) = f2 (De) k2 (4) where: DE is the distance between the rotating axes of the rotating device; 匕 is a constant; and fZ(DE) h is the geometry of the rotating device, the dynamic viscosity of the glass, and the drive module The function of the height of the glass. Therefore, the increase in the hydraulic height AH can be expressed as follows: ΔΗ = KH · w · μ . f2 (De) k2 (5) where: KH is a constant. Under constant viscosity operation, the increase in hydraulic height can be controlled and adjusted by varying the rotational speed w of the rotating device and/or the distance De between the rotating axes of the rotating device. The shear stress generated by the movement of the glass in the drive module due to the rotation of the rotating device distorts the existing heterogeneity in the marshalled glass, thereby reducing its thickness.

On the other hand, the rotating device also homogenizes the molten glass in a manner similar to the mechanical agitator "mixer" used in glass manufacturing in the current state of the art; the demand for high quality glass has allowed the use of a stirrer to reduce heterogeneity and / or the improvement of the heat homogeneity of the glass and the glass [Glass Furnaces, Design Construction and Operation j, φ Society of Glass Technology Sheffield translation, ^175 M] » by the rotation of the drive module (27) The molten glass driven by the device (29) passes over the dome of the corresponding overflow channel (36), and when it completely passes over the side wall (28) that separates the drive modules from each other, Figures 5 and 6 are assigned. The glass flow of all the drive modules (27) of the group meets and flows downward from the outlet (37) in the form of a flat flow (38) of molten glass due to gravity, and enters the molding stage.

The above equation shows that the flow rate q per unit width is a function of the geometry of the drive module and the rotating device, the viscosity of the glass, the rotational speed of the rotating device, and the distance between the rotating axes of the rotating device; it is expressed as follows: 25 q = f [w, μ, DE] (9) In the embodiment of the invention using a single dosing group, the sum of the flow rates of all the drive modules is equal to the total flow of the glass flakes; for all the N components constituting the dosing group Drive module, the total flow rate is: Q = (Σ Qm) 1 a N (10) where: N is the number of drive modules belonging to the dosing group; and Q is the total flow of glass manufacturing, equal to N overflows The sum of them. The sum of the widths of all modules is equal to the total width of the manufactured glass sheets: L = (Σ Lm) 1 an (11) -15- 161469.doc )·¥* 201233644 where: L is the total width of the final sheet glass, It is basically the same as the sum of the sizes of the N overflows that make up the dosing group. The drive modules can have the same width Lm and be dosed with the same flow rate qm, but the edge modules can be dispensed with different flow rates per unit surface to aid in the stretching operation. In a particular operating system, the group of rotating devices and overflow runners are defined by values H〇, Η], Y〇, w, μ, VD, and VR. 'The equivalent value produces the flow rate Qm in each drive module; It is determined that the nominal rotational speed w is sufficient: 昀 provides the appropriate accuracy of the glass flow dosing; and b) produces sufficient homogenization of the molten glass. Therefore, the rotating device functions simultaneously with the glass flow regulating element and the homogenizing element of the molten glass substrate. Due to the change in rotational speed w and the distance De between the axes, the method of the present invention allows for more dynamic and more accurate glass flow control and regulation than conventional "overflow pull-down" methods. From Equations 1, 3 and 7, following the process of the present invention, the temperature decrease or the increase in viscosity of the glass affects the flow change in two ways: a. By increasing ΔΗ, it indirectly increases Qm because of the viscosity. When Δ increases, 'ΔΗ increases (Equation 3); and b) by increasing the equation 7), 苴 directly reduces QM. Because &, in the process of the present invention, the change in the glass flow caused by the temperature change is smaller than the change in the "overflow pull-down" method, and the viscosity change directly affects the flow change in the "overflow pull-down" method. The change in the rotational speed w of the rotating device is as defined by the coefficient (c^ affecting the glass flow rate in the drive module q: (Cqw)i = (% Δ q / %Δ w) (12) 161469.doc -16 - 201233644 Where (Cqwh is the flow rate change coefficient when the speed is changed at the operating point F; is the percentage change of the flow rate; and %^ is rated as the percentage change of the rotational speed. The two changes % A q have the same as ./.A w Direction The change in the distance DE between the rotary axes of the rotating device affects the glass flow in the drive module by the coefficient (CqDE) as defined below: (CqDE)i = (% Δ q / %Δ De) 〇 3) Where: is the coefficient of flow change caused by changing the distance between the axes at the operating point ;; and % is the percentage change of the distance between the axes. Two variations. /. △ (^ and %~ have the opposite The direction of the glass is changed from the initial operational state F defined by qi, w and Dei to the final operational state defined by qZ, W2 and Du & by changing the rotational speed w and / or changing between the rotating axes The distance is De, so follow the following ratio: ((4)丨) / q丨=% Δ w · (CqW) 1 +% △~· (CqDE)i (14) where (q2-q 1) / Q1 is the relative change in flow rate q from the operating point F j. The method of the invention allows for multiple selections to change the intended drive module of the dosing group The glass flow rate q per unit width, which is equivalent to the operating point defined by the distance qi, the speed % and the distance between the axes Dei to the defined operating point ί?2, changing the area corresponding to the module The final thickness of the medium glass. This requires a change in the rotational speed of 0/〇Δ\ν and the inverse of the distance between the axes. Δ DE should follow the above (Equation 丨 4). In the drive module The change or change in the flow rate of the driven glass is mainly as follows: a) the geometry of the mold ear; b) the geometry of the rotating device; c) the viscosity of the glass 'd) the height of the glass in the input channel H〇; e) The overflow channel is topped by 161469.doc •17- 201233644 Height Υ〇; and f) The rotational speed of the joint...the distance De from the axis. Once the geometry of the module and drive components, as well as the glass height and the glass flow rate q per unit width of the overflow dome, are established, the equation of equation (9) described above is followed. The statement q = f [w, μ, De] of equation (9) is determined by: numerical calculation by buck, and b) physical modeling by a drive module having a rotating device and an overflow channel, and Statements represent viscosity, inertial force, gravity, and surface tension. Once the molten glass has been dispensed and dispensed in each of the drive modules (27) belonging to the dosing group (26) and has passed through the overflow channels (36) of the modules, the modules are separated from the adjacent modules. The side wall (28) disappears and all of the molten glass that has passed through the dosing group (26) rejoin, resulting in a flat flow (38) of molten glass that is vertically dripped from the outlet (37) to the forming device due to gravity. This is a stage under the manufacture of glass flakes in accordance with the present invention. It is known that molten glass can develop toward the formation of stable crystalline materials in a process called devitrification, which begins with nucleation and continues with the growth of such crystals; The duration of the temperature of tl depends on the length of time, and therefore the useful life of a certain manufacturing equipment can be limited by this devitrification process. The method of the invention uses a temperature above the devitrification temperature throughout the glass dosing period and even after the formation of the flat stream of glass (38), so that the effective life of the dosing group does not depend on the devitrification of the glass and only by mechanical strength The decision is based on the time of the material used, such as platinum, rhodium or any alloy thereof. The glass which falls vertically from the outlet (3 7) due to gravity and forms a molten glass x flat flow (38) having a flow rate of 161469.doc -18-201233644 per unit width has the following qualities: a) not yet overflowing The solid emblem of the road is "clean" from the surface (40) of the contact of the u body material and can be directly used to form one of the two surfaces of the glass sheet to be formed by the gp face, and b) has been delivered with the overflow The inner surface (39) of the contact with the Han outlet is irregular and should not be part of the final surface of the glass sheet. In some specific embodiments of the method of the invention using the genre group, the outer surface of the flat stream (38) of the fused glass is transferred directly to the outer surface of the glass sheet. The inner surface of the file 'and the flat flow (38) should be cleaned with a cleaning element to improve the portion of the 'W element' and positioned above and spaced apart from the molded body. Other specific embodiments of the invention use two different dosing sets, Figure 12, and there are two molten glass flat flow rafts 8 and 61), the two outer surfaces of which directly form each of the two surfaces of the final glass flake In a particular embodiment of the method of the invention illustrated in the overview of FIG. 3 and the detailed views of FIGS. 7-9, the forming device uses a rotating cylinder (41) as a cleaning element to improve or "clean" The inner surface (39) of the flat stream (38) that has been in contact with the outlet (37); the cylinder (41) is rotated at a speed (in the direction indicated in the figure and below the flat flow (38) of the molten glass and Above the molded body (42). The effect of the round red turn on the two surfaces of the flat flow (38) is as follows: a) The "clean" outer surface (40) is directly transferred to the molded body (42) at the height Z3. The inner edge (43) of the edge (43), and b) the "irregular" is dragged to the inside of the glass substrate that is rotated by the cylinder. The flat stream of molten glass (38) dropped from the outlet (37) is superimposed on the return stream (56) present on the periphery of the cylinder to form a liquid stream (53) which is driven by the cylinder to 161469.doc • 19- 201233644 The area where gravity and drag force are combined, see Figure 7. A portion of the liquid stream (53) is directed to the first edge (43) of the shaped body at a height Z3 and produces a liquid flow (48) that descends along the outer sidewall of the shaped body (42); while the remainder of the liquid flow (53) A portion of the forming liquid stream (54) drives the space between the rotating cylinder (41) and the shaped body (42) to have a space with a certain minimum spacing (46). The liquid stream (54) reaches the height of the second edge (44) of the shaped body at a height 24; one of the liquid streams (54) partially overflows the edge (44) and produces a liquid stream (49) along the shaped body (42) The other outer side wall falls. The remaining glass stream (54) is towed by the rotating cylinder (41) to form a liquid stream (66) attached to the rotating cylinder that deflects the direction of the cylinder drag force in the opposite direction of the gravity of the glass; when the molten glass reaches When the gravity on the glass is similar to the singular region (55) of the drag applied by the rotating cylinder (4丨), there is a break or spalling on the surface of the molten glass with two different streams: a) a portion of the glass stream (56) Keeping attached to the rotating cylinder (41) and driving it until it engages the irregular portion (39) of the flat flow (38) of molten glass and again becomes part of the liquid flow (53), thereby ending the cycle; and b) Another portion of the glass turns to the edge (44) to form an outer surface of the liquid stream (49) that does not fall along the exterior of the shaped body (42). Therefore, the two surfaces of the streams (48 and 49) which will form the surface of the final sheet (5〇) are clean, since the particles of the molten glass (39) in contact with the outlet (37) have been incorporated. The interior of the molten glass matrix in liquid stream (53). The upper end portion of the molded body (42) may have a concave surface (45)' as shown in Figs. 7 and 8 or may be generally smooth as shown in Fig. 9. At the same time, the rotating cylinder (9) can be: a) (4) having a permanent core composed of _ and/or such as Zr 〇 2, 八 12 〇 3 and secret materials for fire materials, with or without Or a certain 161469.doc •20- 201233644 alloy metal coating; or b) hollow and formed by turning, smashing or containing an alloy of some and/or sputum; or having a turn and/or The core of the crane consists of a coating containing platinum or its alloy. The rotating cylinder (41) is rotated by an external mechanical member for controlling and adjusting the rotational speed WC required to control the molten glass layer attached to the cylinder during rotation of the cylinder, and to adjust the rotation Required for inertial force, viscosity and gravity applied to the molten glass particles during rotation of the cylinder. In a particular embodiment of the invention, when the rotating cylinder (41) is hollow (Figs. 7 and 8) and positioned on the concave surface (45) cut into the shaped body (42), 'corresponds to The weight FG of the weight of the cylinder and the weight of the glass thereon is offset by the buoyancy fe applied by the glass of the concave surface (45) displaced by the cylinder (41); therefore, the cylinder "floats" on the molten glass without causing The deformation caused by its own weight. In another embodiment of the present invention, when the upper end portion of the molded body is smooth (Fig. 9) and the rotating cylinder (41) is positioned above the surface, the gravity fg is not offset by the buoyancy FE, and the rotating cylinder It behaves like a curved beam supported at both ends. Two streams (48 and 49) from the edges (43 and 44) of the shaped body (42) flow along the sides of the shaped body to its wedge-shaped bottom region to form an angle in its apex (47); At the apex, the two streams (48 and 49) are joined to form a single stream of glass that is stretched by the traction members (5 turns) to produce the final sheet glass; the final sheet is then divided by members not shown herein to obtain a particular size.

The two dosing groups (26 and 60) are fully or partially supported by a structure (65) that is independent of the structure of the shaped body (64); the two structures (64 and 65) are relatively movable between each other to adjust the shaped body ( 64) The distance from the respective outlet (37) such that the vertical drops of the flat streams (38 and 61) are appropriate. In another particular embodiment of the method of the invention, the sheet glass produced consists of two different glasses A and B separated by a central plane of the thickness of the glass sheet. The process begins with (Fig. 12) the vitrifiable materials A and B are fused in the melting vessels (21 and 66) and the molten glass is refined in the vessels (23 and 67). Thereafter, 'glasses A and B are driven through the channels (24 and 68) towards the dosing group (26 and 60); in the channels (24 and 93), the glass level is maintained via the level regulators (25 and 69) Constant. The dosing groups (26 and 60) each comprise a plurality of drive modules (27); and then each drive module consists of a partition wall (28), at least one rotating device (29) and its own overflow channel such that each The dosing group obtains a flat flow of molten glass having a uniform flow rate per unit width, and thereby produces two flat streams of glass (38 and 61) which are gravity-dependent on each of the two side walls of the forming device (64) While falling vertically, and flowing downward according to two streams of molten glass (70 and 71) formed of two different glasses, the liquid stream (70) is formed of glass A and the liquid stream (71) is formed of glass B.

The position or stage at which the glass undergoes the devitrification temperature or "liquidus temperature" TL in the process of the present invention is as follows: a) in an embodiment of the invention using a dosing group' and thereby using a rotating cylinder for cleaning during the forming stage Element (Fig. 7 to Fig. 9) or partial immersion plate (Fig. 1 〇), once the lateral flow (48 and 49) has been formed, the devitrification temperature is reached, and the side flows (48 and 49) are along the molded body (42) The sides are lowered while being cooled; and b) in the embodiment of the invention using two dosing sets, Figures 11 to 13 once formed for each of the two dosing groups (26 and 60) The two streams of molten glass (38 and 61) reach the devitrification temperature.

The duration of the molten glass remaining below the devitrification temperature is shortened, combined with the fact that the molten glass dosing phase is carried out independently and in a different device from the cooling stage, so that the equipment used in the method of the invention has an effective life longer than "overflow" Pull down the effective life of the equipment used in the manufacturing process. The angle of the lower end region of the molded body which ends at the apex (47) affects the flow stability [H.-J. Lin, W.-1C. Chang.· "Design of a sheet forming apparatus for overflow fusion process by numerical simulation j ; of Non-Crystalline Solids 353 (2007) 2817-252J] 'The small angle gives the molten glass flow above the apex a higher stability, and the method of the invention enables the apex (47) to be used than the "overflow pulldown" method The angle is small. The higher viscosity at the apex of the beginning of the stretch (47) makes the flow more uniform; however, the viscosity is affected by the glass devitrification temperature and the length of time the glass remains below this temperature. In the process of the present invention, the glass distribution over the width of the glass sheet is carried out in the dosing group, and the shaped body is mainly used to cool the glass to the stretching temperature. The advantages of the method of the invention are due to: a) the molded body without internal glass flow restriction requires a smaller width, which makes the angle at the apex (47) smaller; and b) the height of the shaped body is not affected by its mechanical strength The arrow in its lower edge limits this because it does not affect the glass distribution in the width or the uniformity of the thickness of the final sheet glass. In the process of the present invention, 'once the two side streams of the molten glass reach the apex (47) below the shaped body, the glass is stretched by the pulling roll (51) while it is cooled until it becomes a continuous solid sheet glass of a certain thickness; In this drawing process 161 469.doc • 26· 201233644 'the force generated by the surface tension is unfavorable, tending to produce a transverse contraction of the formed glass flakes.

DETAILED DESCRIPTION OF EXAMPLES OF THE INVENTION In the following examples, the process of the present invention was used to make sheet glass having a width of 2500 mm and a thickness of 〇.7 mm. The flow rate or extraction rate of the produced glass was 20 mp/day. The melting and refining (homogenization and purification) of the vitrified raw material is carried out according to the prior art according to the prior art for glass. The viscosity/temperature ratio of the glass is determined by the following values: (μ = 8000 poise, Tv = 1321°C); (μ = 16 000 poise, Τν = 1279. 〇; (μ = 25000 poise, Τν = 1253 C), and (μ = 100000 poise, τν = 1182. 〇. where: μ is the dynamic of the glass Viscosity; and Τν is the glass temperature. After melting and refining, the molten glass enters the channel. Figure 2, Figure 3 and Figure 5' are provided with a liquid level regulator that maintains the glass level at a height H〇, thus reaching the glass. The entrance area of the matching group. The entrance area of the dosing group is shared by all the drive modules constituting the group; the pumping system of all the groups is performed at the same temperature and from the same initial hydraulic height H〇. After the heat adjustment, the glass The arrival temperature is 1321 ° C, that is, the drive module area with a viscosity of 8 Torr. The dosing group or device consists of the following: a) five drive modules separated from each other by the start/money side partition 'The modules contain two rotating devices and overflow channels And b) the final exit, which collects the glass of each of the 161469.doc •27-201233644 that has passed through the overflow of each drive module and pours it into the forming stage as a single stream of molten glass. The width LM of the drive module is 500 mm; the height H of the glass in the suction channel is determined by the level regulator so that the operating conditions of the drive module cause the glass flow to pass over the overflow channel, the dome of the overflow channel It has a height of 〇 8〇mm Y〇. The five drive modules are separated from each other by a spacer with a thickness of 1.5 mm and are constructed of platinum/rhodium alloy and extend to the dome of the overflow channel where the flow of the five modules is formed to a width of 2500 mm molten glass flat flow. In the cross section of each drive module, 'the two rotating devices whose outer diameter D is equal to 220 mm are positioned; the interval between the rotating shafts of the two rotating devices is 18〇mm, and the line connecting the rotating shafts is perpendicular to the driving mode The direction of the glass in the group. Under the influence of the 90 mm diameter of the shaft of each rotating device, the antegrade flow through has a width AD of 230 mm and the width of the reflow glass through Ar is 9 〇 mm. The nominal rotational speed of the two rotating devices is 6 rpm. Both rotate in opposite directions, the direction of the glass on the side of the module, see Figure 5, and the opposite direction to the center glass. The drive blades and shafts of the two rotating devices are constructed of a material having 80% platinum and 20% bismuth; each rotating device weighs 22 0. The duration of each rotating device was 18 months under operating conditions of temperature, working mechanical stress and durability of the platinum-rhodium alloy. The movement of the rotating device produces a return glass flow of 〇 46 m3/s in each drive module, which is 26 times the flow rate of glass manufacturing. It encounters obstacles such as overflow passages, which are driven by the rotating element, and the hydraulic pressure Hl, which limits the forward flow rate until the difference is 161469.doc •28- 201233644 VD-VR is equal to glass manufacturing The flow rate is up to now. The average length of time that the glass remains in each of the drive modules is 37 minutes; during this time, the two rotating devices each perform 222 full revolutions, and each molten glass particle has covered an average distance of 63 meters. In the glass viscosity μ = 8 〇〇〇, the height of the glass passing through the top of the overflow channel is 8 mm, the distance between the axes of the rotating device is 18 〇 mm, and the rotational speed of the rotating device is At 6 rpm, the values obtained by Cqw and Cqde are: CQW = (% Δ q / w) = 〇91; as the rotation speed increases from 6 rpm to 7 rpm, the flow rate increases by Μ.?%. CQDE = (% Δ q / %Δ DE) = -6.6 ; The flow rate decreases to 3 6% as the distance between the rotating axes increases from 180 mm to 181 mm. At this value, when the rotation speed is increased from 6 rpm to 6.5 rpm, the flow rate in the drive module jumps from 4 metric tons per day to 4 31 metric tons per day, and the final thickness of the glass flakes is 〇·7〇111111 jumps to 〇75 mm. This same effect is achieved by maintaining the rotational speed constant at 6 revolutions per minute and reducing the distance DE between the shafts from 180 mm to 177.8 mm. By increasing the distance De between the shafts of the rotating device from 18 mm to 183 mm and simultaneously increasing the speed from 6 rpm to 7 rpm, the flow rate in the drive module is from 4 metric tons per day. To 41 metric tons per day, and the final thickness of the glass flakes jumped from 0.70 mm to 0.72 mm. The glass temperature in the drive module is reduced by rc from 132rc to 132〇. 〇, the viscosity of the molten glass increased from 7982 poise to 8114 poise. The response to the glass flow rate 4 is as follows. a) The hydraulic height ΔΗ increases as it passes through the rotating device* which causes the first change in the flow rate = i 5 ()%; and... passes I61469.doc -29 - 201233644 1.64% When the overflow channel is increased, the viscosity increases by y and the second change of the flow rate.

The glass has a viscosity of 16 GGG, at a temperature of 1279 t. By rotating the area of the cylinder / that is, the temperature of the a glass is lower than the temperature of the molten glass in the area of the rotating device belonging to the drive module. The detailed views of Figures 7 and 8 are depicted to include a rotating cylinder. a device for forming a cleaning element and a molded body; the molded body has a width of 20 cm and a concave surface having a depth of 14 cmi in the upper end ;; the rotating cylinder is made of a platinum-iridium alloy and has an outer diameter of 12 cm and 2 Thickness of mm Assuming that the density corresponds to platinum _ 161469.doc 201233644 铑 alloy 'molten glass density is 2·60 gram / cubic centimeter and the average thickness of the glass on the non-immersed area of the rotating cylinder is 15 mm, the hollow cylinder floats on the molded body On the molten glass contained in the concave surface, the immersion depth is 55 mm. The rotation speed of the rotating cylinder is 0.5 rpm. • Between the static wall of the concave surface of the molded body and the dynamic wall of the rotating cylindrical portion immersed in the glass The shearing of the glass forces the rotating cylinder to withstand a total torque of 149 Newtons. Once the rotating cylinder has been modified or "cleaned" to the lower surface of the flat flow of the molten glass and forms two streams of glass through the upper edge of the shaped body, the molten glass is Flows along each of the two sides t of the molded body. The viscosity of the glass in this area is 24,000 poise, which corresponds to the temperature of M 1255»C. Then, the two streams flowing down each side of the molded body are cooled to reach the lower apex with a viscosity of 1 〇〇, anchored, corresponding to a temperature of 1182 ° C; where the two glass streams are joined Together to form a sheet of molten glass. The vertical height of the molded body was 81 cm, and the glass temperature was 〇.9 per cm of the molded body. The rate of sputum is reduced. In the apex below the shaped body, the molten glass flakes are stretched by a pulling roll to form a continuous solid sheet glass which is then divided to obtain a predetermined flat sheet glass. • [Simplified Schematic] • The view is based on the view and cross-section of the “closed insulated pipe” of the molding tool used to manufacture the “overflow pull-down” of sheet glass. 02. - Perspective view of a device for making sheet glass in accordance with the method of the present invention.
