Thus, the "first" and "second" constituent elements can each be used selectively or interchangeably. 1 is a perspective view of a thin plate casting apparatus according to an embodiment of the present invention, the thin plate casting apparatus according to this embodiment including an upper casting roll 111 and a lower casting roll 112 which are arranged up and down and rotated in opposite directions, and 7 The inflow portion of the upper casting roll 111 and the lower casting roll 112 is used to supply the nozzle assembly 113 of the melt. The upper casting roll 1U and the lower casting roll 112 are disposed to be spaced apart by a predetermined interval. The melt supplied into the nozzle assembly 113 is dispersed in the nozzle assembly 113 and passed between the upper casting roll 111 and the lower casting roll 112. Thus, the molten metal discharged from the inside of the nozzle assembly 113 is cooled and solidified in the process of passing between the upper casting roll lu and the lower casting roll 112, and then discharged from the upper casting roll 111 and the lower casting roll 112 in the form of a thin plate of a predetermined width. 2 is a block diagram for explaining a control system of a thin plate casting 4 apparatus according to an embodiment of the present invention, and a thin plate casting apparatus according to an embodiment of the present invention includes: for measuring formation of an upper casting roll 1U and a lower portion An oxide film thickness measuring unit 12 for measuring the thickness of the oxide film on the surface of the casting roll 112; a thin plate defect measuring unit 14 for measuring defects on the thin plate S; and a control unit for receiving signals from the oxide film thickness measuring unit 120 and the thin plate defect measuring unit 140 13〇; the brush assembly 150; and a drive unit 丨6〇 that operates in accordance with the control of the control unit 130 to operate the brush assembly 150. The structure and function of each component are as follows. The oxide film thickness measuring unit 120 includes a first sensor 121 disposed at a position adjacent to the upper casting roll lu, a second sensor 122 disposed at a position adjacent to the lower casting roll 112, and a first sensor 121 and a second, respectively The oxide film thickness calculation unit 123, 124 to which the sensor 122 is connected. The first sensor 121 and the second sensor 122 correspond to the edge portions of the upper casting roll Π1 and the lower casting roll 112, thereby generating signals corresponding to the oxide films formed on the surfaces of the edge portions of the upper casting roll 111 and the lower casting roll 112. The signals generated in the first sensor 121 and the second sensor 122 are respectively transmitted to the oxide film thickness calculating units 123 and 124, and in the oxide film thickness calculating units 123 and 124, the upper casting rolls 111 are calculated based on the transmitted signals. And the thickness of the oxide film on the surface of the edge portion of the lower casting roll 112.

In other words, when an oxide film having a predetermined thickness or more is formed on the surface of the edge portion of the upper casting roll 111 and the lower casting roll 112, the control unit 130 determines the brush unit to operate the upper and lower casting rolls. The oxide film on the surface of 丨, 112 is removed so that it reaches a predetermined thickness or less. By this process, when it is judged that the oxide film formed on the surface of the edge portion of the upper casting roll 111 and the lower casting roll 112 is reduced to a predetermined thickness or less, the control portion 13 stops the action of the brush assembly. According to the signal transmitted from the sheet defect measuring unit 14A, it is judged that there is a thin plate edge portion formed on the surface of the thin plate s as a result of an excessively formed oxide film on the surface of the edge portions 9 of the upper and lower casting rolls U1, 112. In the case of a defect such as a defect, the control unit 130 operates the brush unit to remove the oxide film on the surfaces of the upper and lower casting rolls 111 and 112 to a predetermined thickness or less. Further, by the brush assembly 150, the oxide film formed on the surface of the edge portion of the upper casting roll 111 and the lower five casting rolls 112 is reduced to the set thickness or less, and thus the defect of the surface of the thin plate cannot be measured by the thin plate defect measuring unit 140. At this time, the control unit 130 stops the operation of the brush unit 150. The structure of the brush assembly 150 will be described using FIG. Brush assembly 150 includes first and second brush assemblies 151, 152. The first and second brush assemblies 151, 152 are respectively disposed at positions adjacent to the upper casting sheet 111 and the lower casting rolls 112, and are provided to be movable toward the upper casting roll 111 and the lower casting roll 112. The first and second brush assemblies 151, 152 are respectively driven relative to the corresponding upper and lower casting rolls 111, 112. Hereinafter, for convenience of explanation, only the 15th brush assembly 151 will be described. The first brush assembly 151 includes a rotating shaft 151a that is disposed to be movable toward the casting pro 111 and at least one brush 151b, 151C that is fixed to the rotating shaft 15la. The rotation of the brush assembly 151, i.e., the rotation of the brushes 151b, 151^, the surface of the casting roll 111 is ground by the brushes 151b, 151c. Here, 20 in Fig. 1 only shows one of the brushes 152b constituting the second brush unit 152. However, according to an embodiment of the present invention, there is no limitation on the number of brushes in the case where the surface of the cast edge portion is ground and the brush corresponds to both edge portions of the casting roll.

The overall operation of the thin-plate casting apparatus 10 according to an embodiment of the present invention thus constructed and the specific functions of the respective constituent units will be described using the respective drawings. The melt discharged from the nozzle assembly 113 flows between the upper casting roll lu and the lower casting roll 112, and during the passage of the upper casting roll 111 and the lower casting roll 1J 2, the melt is cooled and solidified to a thin plate shape of a predetermined width. discharge. 15 In the process of performing such a process, the first sensor 121 and the second sensor 122 disposed adjacent to the upper casting roll 111 and the lower casting roll 112 are transferred to the oxide film thickness early 123, 124 and formed in the upper scale. η and the information (signal) corresponding to the oxide film on the surface of the lower casting roll 112, in particular, the oxide film formed at the edge portion. The thickness of the oxide film formed on the edge portions of the upper and lower casting pros 111, 112 is calculated based on the signal generated in the first sensor 121 and the second sensor 122, and the thickness of the oxide film is measured. The control unit 13 transmits the calculated result. When the thickness of the oxide film on the surface of the edge portion of the upper prayer roll 11 1374065 111 and the lower build-up roll 112 transmitted from the oxide film thickness calculating units 123 and 124 is equal to or greater than the set value, the control unit 13 determines it. The driving unit is operated, that is, the first and second driving units 161a and i61b and the first and second fifth cylinders 162a and 162b connected to the rotating shaft 151a of the first and second brush units 151 and 152 are operated. . Therefore, the brushes 151b, 15ic of the first and second brush assemblies 151, 152 rotate while being in contact with the surface of the edge portions of the upper casting roll 111 and the lower casting roll H2, and as a result, are formed at the edges of the upper casting roll 111 and the lower casting roll 112. The oxide film on the surface of the portion is removed or the thickness thereof is decreased by β 10 . By the process, when the thickness of the oxide film formed on the surface of the edge portion of the upper casting pro 111 and the lower casting roller 112 is less than a set value, the control portion 130 stops the operations of the first and second driving portions 161a, 161b and the first and second cylinders 162a, 162b, separating the first and second brush assemblies 15i, ι52 from the upper casting roll 111 and the lower casting roll 112, and The rotation of the brushes 151b, 15 151c is stopped. On the other hand, the thin-plate defect measuring unit 14 provided on the transport path of the thin plate S transported by the upper casting roll lu and the lower casting roll 112 detects defects existing on the surface of the thin plate S, that is, due to the upper and lower portions. The defects of the edge portion of the thin 20-plate formed by the excessively formed oxide film on the edge portions of the aging rolls 111 and 112 are transmitted to the control unit 130. The control unit 130 determines whether or not there is a sheet defect based on the signal transmitted from the sheet defect measuring unit 14A. When it is determined that there is a defect, the control unit 13 causes the first and second driving units (6)a, the secret and the first and second gas red.上述· The above-described process is carried out to remove the rolled film on the surface of the edge portion of the upper and lower casting rolls 112, 112, 1,374065, so that it reaches a predetermined thickness or less. The thickness of the oxide film formed on the surface of the edge portion of the upper casting roll hi and the lower casting roll 112, which is the heat transfer barrier film that hinders the heat transfer of the liquid to the upper and lower prayers ill, 112, is reduced by such a grinding process. . 5 Therefore, the hot upper portion and the lower casting rolls 111, 1 12 of the bright liquid are particularly efficiently transmitted by the edge portions delayed in solidification due to the small cooling energy, so that the edges of the upper and lower casting rolls m, 112 are also uniform.

Further, cooling gas injection devices 221 and 222 for ejecting cooling gas are provided at both side portions of the discharge portions of the upper casting roll 211 and the lower casting roll 212, respectively. The cooling gas injection devices 221 and 222 receive the cooling gas from the outside and are electrically connected to a control unit to be described later. 2〇 Therefore, the cooling gas ejecting devices 22 j and 222 eject the cooling gas to both edge portions of the thin plate s discharged from the upper casting roll 211 and the lower casting roll 212 in accordance with the control signal from the control unit. 4 is a block diagram for explaining a control system of a thin plate sizing apparatus according to an embodiment of the present invention. As described above, the thin plate casting apparatus according to an embodiment of the present invention 13 1374065 includes: being disposed on a casting roll 211 The cooling gas injection devices 221 and 222 on both sides of the discharge portion of 212, the control unit 223 that controls the operation of the cooling gas injection devices 221 and 222, and the movement path provided on the thin plate S and measure the defects on the edge portion of the thin plate The thin plate lacks the measurement unit 224. The cooling gas injection devices 221 and 222 provided on both sides of the discharge portions of the casting rolls 211 and 212 respectively supply cooling gas from the outside corresponding to both edge portions of the thin plates 2S discharged from the casting rolls 211 and 212. According to the control signal of the control unit 223, the flow rate control unit such as a valve mounted inside the cooling gas injection devices 10 221 and 222 operates, whereby the injection amount of the cooling gas discharged through the cooling gas injection devices 221 and 222 can be controlled. And injection time. Here, the type of the cooling gas is, for example, nitrogen gas, argon gas or the like. The thin-plate defect measuring unit 224 is provided on a transport path of the thin plate s, which is a position corresponding to the thin plate S discharged from the upper casting roll 211 and the lower 15-part casting roll 212, and measures defects existing on the surface of the thin plate S, that is, both edge portions. . The thin plate defect measuring unit 224 that performs this function is, for example, a visual sensor. The control unit 223 electrically connected to the thin-plate defect measuring unit 224 is electrically connected to the cooling gas injection devices 221 and 222 to control the operation of the cooling gas injection devices 2 221 and 222. The overall operation of the thin-plate casting apparatus according to one embodiment of the present invention thus constructed and the specific functions of the respective constituent units will be described using the respective drawings. The molten metal discharged from the nozzle assembly 213 is supplied between the upper casting roll 211 and the lower casting 14 1374065, and the molten metal is cooled and solidified in the process of forming the pro-211 and the lower binding pro 212. The width of the thin plate is discharged. - The thin-plate defect measuring unit 224 on the transport path of the thin plate S transported by the upper casting report 211 and the lower-twisting report 212 measures the defect on the surface of the thin plate S, that is, the edge dam The damage causes the melt to leak excessively to the outside, and the edge portion of the thin plate protrudes outward from the predetermined width, and transmits the measurement signal to the control portion 223. The control unit 223 determines whether or not there is a plate defect based on the signal transmitted from the thin-plate defect measuring unit 224. When it is determined that there is a sheet defect, the control unit 223 10 operates the cooling gas injection devices 221 and 222. Therefore, the cooling gas is sprayed to both edge portions of the thin plate which is not completely cooled and solidified by the upper portion and the lower portion, and the two portions of the thin plate are cooled at a speed higher than that of the self-riding. By the cooling gas to be ejected, the molten material that has diffused through the edge portion of the damaged portion 15 to the outside of the predetermined width is cooled at a relatively high speed to prevent the edge portion of the thin plate from protruding outward to the width of the entire thin plate. Increase the problem above the predetermined width. For example, according to the defect width of both edge portions of the thin plate, that is, the degree of the portion which is smaller than the width of the ridge of the 4 plate, the adjustment unit in the body-adjusting cooling gas 20 body spraying device 221 222 adjusts the injection of the cooling gas. Fm can adjust the injection amount of the cooling gas if the degree of opening and closing of the valve is over.

Fig. 6 is a view showing an arrangement state of the mixing member constituting the regulating dam 5 in the nozzle unit when an excessive amount of molten metal flows toward the center portion. If you refer to Figure 6, the center of the sheet. The state in which the thickness Tc of p is thicker than the thickness □6 of both edge portions to a set value or more means that an excessive amount of solution flows to the central portion of the internal space 313c of the nozzle unit 313. Therefore, the operator rotates the agitating member 32 by the knob 323 of each of the adjustment fields 32, so that a larger amount of molten metal flows toward both edge portions of the internal space 313c of the nozzle 10 assembly 3?. According to the arrangement state of the adjustment dam 320, that is, the arrangement state of the agitation member 321, a larger amount of molten liquid flows toward both edge portions of the internal space 31 of the nozzle assembly 313, and the result is passed through the upper and lower casting rolls 3U, 312. On the other hand, the thickness of the edge portion of the discharged thin plate is increased, and the 15th optimum thickness distribution as shown in Fig. 8 is obtained. Fig. 9 is a view showing an arrangement state of the mixing member constituting the adjustable can in the nozzle unit in the case where an excessive amount of molten metal flows to the edge portion. Referring to Fig. 9, the thickness Tc of the central portion of the thin plate S is set to be equal to or smaller than the thickness Te of the both edge portions, or the thickness Tc of the central portion is equal to the thickness Te of the both edge portions. The both edges of the internal space 313c flow excess melt. In this regard, the operator rotates through the knobs 323 of the respective adjustment dams 32 搜. The jaws 321' cut off a portion of the solution flowing to both edge portions, causing a large amount of molten metal to flow toward the central portion of the internal space 313c of the nozzle unit 313. According to the arrangement state of the adjustment dam 320 shown in Fig. 9, a large amount of 18 stunners are made to the sputum assembly 31331 through the upper part and the lower qiu town. Therefore, the center "moves", and the thickness of the central portion of the thin plate s which is discharged by the rolls 311 and 312, has an optimum thickness distribution as shown in Fig. 8. For example, Maintaining the smooth flow of the bright liquid. At the time of L 贳k, each stirring dam 320 stirring member 321 is made streamlined. That is, 32H^ > as shown in Fig. 9, the two parts of the mixing part ^ have no width. (4) _ frequency, but having a shape whose width gradually increases toward the central portion. Industrial Applicability The thin plate praying device according to the present invention as described above is imposed on the (four) solidified fragile region, that is, the edge portion of each casting roll In the polishing process, the oxide film having the function of the heat transfer barrier film is removed or the thickness of the oxide film is reduced, so that a solidification angle of a uniform thickness can be formed at the edge portion of the cast fiber, thereby producing a thin plate having a good quality at the edge portion. Further, the thin plate praying apparatus according to the embodiment of the present invention injects a cooling gas toward the discharge (four) plate from the casting roll to forcibly cool the solution, thereby suppressing the solution from excessively leaking to the outside, thereby preventing the solution from being excessively leaked to the outside. Therefore, a thin plate having a width larger than the set width is manufactured. Further, according to the thin plate casting apparatus of one embodiment of the present invention, the flow adjustment _, the control solution is set in the sleek flow (four) nozzle assembly. Therefore, there is an effect of maintaining the shape of the cross-sectional thickness of the thin plate to be suitable for the shape of the rolling process. As a result, the final product obtained after the calendering process is of course maintained in a uniform thickness shape. [1] Simple description FIG. 1 is a view according to the present invention.
