Background The main technical field The present invention relates to the field of continuous method. ^ 1-_ 阚 Explanation of Craftsmanship “In the continuous steel casting method, molten metal is poured into a large container called " feed tank " through a hidden nozzle (SEN). A water-cooled copper I can be in the mold. When the steel casting contacts the wall end of the copper mold, it will begin to solidify, and the child steel plate (sheet) will continue to reduce its casting rate. The thickness of the mold is about 9 to 2 inches, but the thickness of a thin steel plate (sheet) casting is only about 2 to 4 inches. The width of the steel plate (sheet) is generally quite large, which is basically 60 to 72 inches. A mold flux layer is maintained at the free surface end of the metal, which can protect hot metal from being oxidized by gas and can provide a thin lubricating layer between the lowered steel plate (sheet) and the mold wall surface. The results of several studies on the phenomenon of fluid flow in the mold of a steel plate (piece) show that the molten metal fluid in a casting mold has a considerable influence on the quality of the surface and subsurface of the metal casting it produces. The molten metal discharged by the spray injection is equivalent to It is discharged at a flat angle and sprayed on a narrow wall surface. This will cause the phenomenon of upper and lower reflows to be formed. This is shown schematically in the general flow pattern in Fig. 1. The upper reflow phenomenon is caused at the free surface end. _Standing wave. Basically, its fluctuation height changes with the passage of time. Standing waves and related turbulences that constantly change at the free surface end are considered to be steel plate castings when performing this process The main cause of most of the defects. This paper size applies the Chinese National Standard (CNS) A4 specification (210X297 mm) 555607 A7 __ B7 V. Description of the invention (2) Due to other physical factors (such as sliding The non-uniform clogging phenomenon of the gate and the injection port) and turbulence, so not only cannot maintain a symmetrical flow pattern on the two sides of the mold, but it may continue to change over time. The fluctuation height must be determined by the SEN. It depends on the depth of the dive, because basically the fluctuation is higher than the shallow dive condition. The fluctuation height must also depend on the angle of the orifice end and the opening range. The angle and the small opening range produce a high wave height. Surface turbulence and standing waves can affect the most important factors of the quality of the surface piece. The wave and recirculation phenomena on the two sides are constantly changing. Therefore, it adversely affects the quality of the rotating part. As the effect of the blocking phenomenon of the sliding gate or the spray inlet is felt, the flow will be further deflected. The phenomenon of deflection will increase the mold flux. The probability of mist. If the incident point is pushed deeper into the lower end of the mold, it can be sprayed downward from the horizontal end at a large angle and help reduce the surface turbulence and wave height. However The lower incidence point results in a thin solidified shell at the exit end of the mold and the risk of leakage of the mold itself will be combined. Another problem is the deeper back

The flow phenomenon brings the inclusion to a deeper position downward, thereby affecting the quality of the metal piece. A The purpose of this month is to provide a continuous metal forming device and a method '' which can provide a relatively flat and free surface with a small flow rate. In addition to providing effective melting fluid and more efficient Ground removal of 4 things = low risk of U leakage. This will predictably reduce the appearance of flaws in the casting surface and sub-surfaces, as well as surface fluctuations and -5-

Even though the content of the description here is similar to the field of inhibiting the surface = in the steel turning method, 'but De Derong, etc., can be the most effective in the present invention and other benefits that accompany it ^ Λ. Α, ,, and other Successfully obtained in the application project. According to the contents of 7F disclosed in the present invention or the smoke of the sister of each wear + 贝 贝 Betty one of the general skills in the art of this invention, then the political benefits of the β will be more prominent . The hair: I includes a metal container system of molten state which can be used to make this state, Wu Er and 14, casting method, which can provide molten metal flow. In general: the device of the present invention includes a molten state system for casting molten metal, the system includes: ⑷-a kind can be used to contain-molten state to t Γ Γ, which is suitable for containing and distributing the casting The molten metal s # device has several inner surfaces and the molten metal will form an upper surface; (b) a hidden nozzle that extends from below the upper surface, and (C) a set of flows A regulator member is disposed at a position between the at least one of the inner surfaces and the submerged nozzle. It is possible to arrange the inner / withdrawal member at a position very close to the upper surface end of the molten metal so as to prevent the formation of waves in the upper surface of the molten metal. At the same time, a submerged flow regulator member can also be used, which is completely submerged to a certain depth below the upper surface of the molten metal and a position very close to the submerged jet inlet so as to affect the upper and lower parts thereof. Recirculation mode and thereby trigger turbulence and fluctuations. The latent flow regulator also has an effect that it can be used in a continuous mold to attenuate standing waves at the surface end of the molten metal. -6-555607 A7 B7 Take it is' set the surface or the submerged film, & 欤 / / Erliuqiuqiu member on each side of the submersible spray inlet, in order, ^ And a hand-held device on either side of the submerged jet inlet, and the surface or submerged flow regulator component. Basically, the surface flow regulator members extend into the molten metal, even though they can stop just above the free surface of the molten metal so as to prevent the formation of waves in the upper surface of the metal. Basically, the submerged flow regulator member is disposed at a position below the surface of the molten metal so as to prevent the molten metal flow flowing from the submerged nozzle from flowing up and down. Usually, the molten metal surface will have a melting layer. In a particular embodiment, at least a portion of the surface flow regulator member or bracket can thus extend through the melting layer and / or the beta dissolution metal. In other embodiments, the entire set of latent flow regulator members may be disposed within the molten metal and at positions below the melting layer. In general, the present invention does not place any restrictions on the geometry of the surface or submerged flow regulator member. For example, in one embodiment, the surface flow regulator member may have a special shape so as to provide a thinner shawl to extend through the dissolution layer and a wider portion to extend into the molten metal. . In another embodiment, the surface flow regulator member includes a plurality of tines so as to extend through the melting layer and a wider portion so as to extend into the dazzling metal. In still another embodiment, the surface flow regulator member includes a lower end portion which is not only gradually sharpened by the submerged nozzle inlet end but also faces the inner surface end so as to form an approximately trapezoidal shape. In an alternative embodiment, wherein the flow regulator member can be submerged to the fifth, the description of the invention (5) the molten metal is located at a position below the melting layer, and various geometries can be configured so that Reducing turbulence and fluctuations caused by the molten metal exiting the latent j-jet nozzle. In the only embodiment described above, the latent flow regulator member may have, for example, a ' even-angled, trapezoidal, or tapered geometry. However, we should understand that the geometries disclosed in the present invention are just a few examples of different geometries, which can smoothly prevent turbulence when it allows as much as possible on the free surface of the metal Produces a free flowing and consistent melt flow. Similarly, other geometries can be successfully used to form a surface or submerged flow regulator member. The surface flow regulator member may be supported by any suitable mechanical means, such as by a bracket attached to the mold, so as to be able to touch the free surface of the metal or be functionally accessible to the metal Free surface. Attachments attached to the structure other than the mold can also be used to support the surface flow regulator member. In a specific embodiment of the present invention, the submerged flow joint member can also be assembled at the submerged jet inlet end. Based on the material and accessory records, it can use any suitable heat-resistant material, such as refractory ceramic materials. A preferred method is that the surface or the hidden regulator member does not contact the inner surface of the mold to prevent the solidification of the metal and the melting " the movement of the tile liquid mud into the rotary mold is interrupted simultaneously. Another aspect of the present invention is that the flow regulator member or other turbulent and / or fluctuating impedance allows the submerged nozzle to selectively guide the molten metal at two degrees or above the horizontal plane. The flow of fluid (not the angle of the downward flow of Lu Er). This item is helpful in # making process. 555607 A7 ------------ B7____ V. Description of the invention (6) '- It can remove inclusions more efficiently, and can reduce the risk of casting leakage in the newly solidified layer when the temperature is lower than high temperature. When the hot molten metal is introduced to a too low position and too close to the mold The position of the downstream end thus causes it to come out of the mold end. The molten metal container system for casting molten metal of the present invention also includes (a) a container that can be used to contain molten metal, It is suitable for containing and distributing the molten metal for casting, the container has several inner surfaces and the molten metal forms an upper surface; (b) a hidden spray inlet extending from below the upper surface ; And (c) available to stop in the molten gold The method of forming the wave in the upper surface of the metal.

As described above ', the purpose of preventing the formation of waves in the upper surface of the molten metal can be achieved smoothly by applying mechanical means, hydraulic force, or electromagnetic force. The submerged spray nozzle can guide the molten metal at an angle higher or slightly lower than the horizontal plane, even if the angle is preferably lower than the horizontal plane (that is, U0 degrees below the horizontal plane). Therefore, the present invention can provide a simple method to reduce the turbulence and wave effect that must occur in the continuous metal prayer process. In one embodiment, 'a time-fired material or other heat-resistant member (commonly referred to as a "surface flow regulator") is inserted, otherwise it is engaged to the free surface end, preferably from the free surface end. The top starts and approaches, preferably on either side of the submerged nozzle. The surface flow regulator can smoothly prevent the backflow and fluctuations that occur at the top, and in turn, slow the surface significantly. Flow rate, and can be made into a nearly flat free surface. This structure is shown schematically in Figure 2. In other embodiments of the invention, there is a piece of refractory material or other heat-resistant member (usually Called a "submerged flow regulator,") is placed at a position below the surface of the molten metal, and can interrupt the normal reflow mode of the molten metal when entering from the submerged jet inlet end, The standing wave intensity can be generated by this. Various: The g's set of this force is as shown in Figure 9 and i 〇. By using the method and device disclosed in the present invention, it can effectively reduce or even can Do not worship defects caused by free surface fluctuations or turbulence. = It will solidify when it comes into contact with the mold wall surface end, so it is best not to let the salty surface or the hidden flow regulator directly contact the wall surface end of the mold -10-

It is therefore necessary to maintain a gap between the surface or the hidden flow regulator and the wall end of the mold. Shown in Fig. 3 is a side view of the mold as described above, which has a surface " inverter. This view has been tested and proven to work smoothly in a small hydraulic model. The shape, size, and location of the surface flow regulator must depend on the particular system. Neither the surface nor the hidden flow regulator will slow down the flow velocity of the fluid to the area near the free surface, where the metal will strike in large quantities. A general three-dimensional schematic diagram of the surface flow regulator system is shown in Fig. 3a. Because the surface flow regulator is the flow of the P low free surface, the flow can be evenly distributed on both sides of the submerged spray population and greatly reduce the phenomenon of bias flow. The method and apparatus disclosed in the present invention are expected to provide better control of the continuous casting process and to greatly improve the quality of the metal rotating parts produced thereby.

Patent application model refers to the intense reflow mode 4, which is usually generated by the submerged nozzle in a continuous casting process, even if the molten metal flow 4 was compared with It is not desirable to be guided, that is, to exit from the end of the submerged nozzle 3 at a very horizontal angle. The position of the hidden flow regulator 22 can be fixed in various ways. As shown in Figs. 9a and 9b, the submerged flow regulator 22 can be fixed to a part of the submerged nozzle 3 by any suitable coupling means 23 sufficient to resist the high temperature of the molten metal 2. For example, high melting point steel castings or pottery brackets can be used.

In each example, it is desirable to maintain a gap between the inner surface 8 of the die 1 and the submerged flow regulator 22 for reasons discussed above. 10a-10c show still another embodiment of the present invention. In addition to the submerged nozzle 3 shown in Fig. 2c, this embodiment of the present invention utilizes a submerged flow regulator 22 and an additional device 23 as shown in Figs. 9a-9c. As mentioned before, in order to minimize the standing wave and turbulence energy, it is usually best to provide a slightly downward passage 4 so that the molten metal can smoothly flow out from the end of the submerged jet inlet 3.

The inlet 3 'can discharge the molten metal flow 4 and can reduce or eliminate the current or standing wave. At the same time, the submerged flow regulators 22 are not limited to a particular size, but it is best to select them according to the specific application project they are engaged in. Similarly, it must depend on the parameters of its application, and the exact position of the submerged flow regulator 22 and the submerged jet inlet 3 and the free surface 1 of the molten metal can be changed so that For best results. For example, even though the hidden flow rate controller 2 2 shown in the figure is entirely parked below the upper surface 10 of the molten metal 2 and at a position below the melting layer 9, the hidden flow rate A part of the regulator can also contact the melting layer and / or the upper surface of the molten metal.
