Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a facility for manufacturing a thin metal plate by a molten metal quenching method, and particularly to a pouring control device suitable for appropriately guiding a molten metal onto a cooling surface. About. [Prior Art] In a method of manufacturing a thin metal plate, which is manufactured by quenching a molten metal typified by an amorphous metal, the molten metal is appropriately poured onto a cooling surface moving at an extremely high speed. In order to manufacture a good metal sheet, it is important to maintain a fixed amount of molten metal and control the pouring amount so that the specified amount is continuously discharged in accordance with the situation of the preceding and following processes. is there. In addition, this molten metal is prepared, melted,
Although smelting is performed, it is desirable that the molten metal in several units be continuously poured in this facility to produce a thin metal plate. The method of controlling the pouring of molten metal in the conventional molten metal quenching method, although the production volume was small in some cases,
As described in Japanese Patent No. 33062, a crucible for melting and holding is provided above a cooling roll, and the pouring amount is controlled by adjusting the internal pressure of the crucible. However, in this case, the molten metal can be poured only once in a dissolvable unit, and it is impossible to continuously pour multiple units. In this method, the molten metal is usually discharged. Since there is no stopper mechanism for controlling the amount, it has not been considered to perform the pouring control flexibly according to various operating conditions. In addition, some of the conventional continuous casting methods that employ a tandem device are also used.However, in this case, the pouring control such as rapid opening and closing and multi-stage opening and closing that are particularly required in the molten metal quenching method is taken into consideration. I didn't. [Problems to be Solved by the Invention] In the above prior art, in order to aim at mass production of a thin metal plate by a molten metal quenching method, pouring control by continuously supplying a multi-unit molten metal,
No consideration is given to the stepwise adjustment control of the nozzle opening degree at the start and end of pouring and the rapid opening / closing control of the nozzle, so that continuous pouring of multi-unit molten metal cannot be realized,
There were problems such as difficulty in obtaining good properties of the metal sheet formed at the start of production. An object of the present invention is to continuously cast a multi-unit molten metal in a pouring control device of a molten metal quenching facility for producing a thin metal plate by pouring a molten metal in a dissolvable unit onto a cooling surface,
A large amount of sheet metal can be manufactured continuously, and even at the start of pouring, the tip of a sound metal sheet having a good shape can be formed, and further, a stationary part following the tip of the sheet metal is formed. It is an object of the present invention to provide a molten metal quenching equipment pouring control device capable of performing the above-mentioned. [Means for Solving the Problems] The object is to provide a tundish having a pouring nozzle,
A pouring control device for a quenching equipment for molten metal, which comprises a stopper for adjusting an outflow amount of the molten metal to be poured from the pouring nozzle, and pours the molten metal onto a cooling surface to produce a thin metal plate. First and second stopper opening / closing control means for individually adjusting the opening / closing of the stopper, and the opening / closing degree of the first stopper opening / closing control means in a stepwise manner to the first opening / closing degree and the second opening / closing degree, respectively. And a slit nozzle having a space filled with a desired amount of the molten metal is provided in the pouring nozzle, and the first stopper opening and closing control means is provided with a space in the slit nozzle. This is achieved by providing means for adjusting the opening / closing speed at which the desired amount of molten metal is filled and the opening / closing speed at which a steady pouring amount is secured. [Operation] The continuous opening or closing function of the stopper is such that, at the start of the production of a thin metal plate, that is, at the start of pouring, first, the slit nozzle portion provided following the pouring nozzle relatively slowly and melts. After filling, the stopper is opened at a relatively high speed to operate so as to secure a steady pouring amount. Thereby, the tip of a sheet metal formed by being cooled rapidly on a cooling surface such as a cooling roll, and
Good products with good shape and properties can be obtained for the subsequent stationary part. Here, the speed of the continuous opening or closing function of the stopper is determined by taking into account various conditions such as the shape and dimensions of the slit nozzle, the properties and temperature of the molten metal, and the steady pouring volume, and the optimum opening or closing speed for each condition. It has a function that can be set. On the other hand, a continuously formed thin metal sheet is usually wound up in a coil shape after leaving a cooling surface such as a cooling roll. However, since the amount that can be wound as a coil is naturally limited, it has to be wound on a different winding machine for each coil equivalent amount. At this time, it is necessary to temporarily stop the formation of the continuously manufactured metal sheet. In this operation, the instantaneous pouring can be interrupted by providing and operating the quick opening and closing mechanism of the stopper separately from the continuous opening or closing mechanism, and therefore, the multi-unit molten metal can be continuously poured. This makes it possible to continuously produce a large number of metal sheets and process them as a large number of coils. [Embodiment] An embodiment of the present invention will be described below with reference to FIGS. 1, 2, 3, and 4. FIG. The molten and smelted molten metal 1 is conveyed by a container (not shown) such as a ladle and transferred into the tundish 2 by a predetermined amount. A pouring nozzle 3 is provided at the bottom of the tank 2, and a stopper 4 serving as a valve is combined with the pouring nozzle 3 to adjust the amount of the molten metal 1 flowing out from the pouring nozzle 3. Below the pouring nozzle 3, there is provided a slit nozzle 6 which is supported and fixed to the tundish 2 by a clasp 5 and has a space portion 7, and the molten metal 1 passes through the pouring nozzle 3 and the slit nozzle 6,
It is jetted into a minute gap G between the slit nozzle 6 and a cooling roll 8 rotating at a very high speed in the direction of the arrow, and is rapidly cooled to form a thin metal plate 9. The stopper 4 is provided with a core rod 13 on an arm 12 which moves linearly in the vertical direction along a guide rod 10 via a bearing 11.
Mounted via A male screw provided in parallel with the guide rod 10 and driven by the servomotor 14 through the coupling 15.
There are 16. A nut 17 is meshed with the male screw 16, and the nut 17 is housed inside the arm 12 and is stopped so that it cannot rotate in the circumferential direction of the screw.
When the nut 17 rises due to the rotation of the arm, the arm 12 is pushed up. Conversely, when the nut 17 descends, the arm 12 can be freely lowered without forcibly lowering the arm 12. The axial fitting with 12 is accommodated in a loose state. The upper and lower ends of the guide rod 10 and the male screw 16 are supported by a lifting frame 18. Lifting frame 18
Is engaged with a base 19 fixedly attached to the outer wall of the tandem 2 by a key-shaped guide 20 which is freely slidable in the vertical direction, and further, a liquid fixed to the base 19 below the base 19. Pressure or pressure cylinder 21 (hereinafter simply cylinder)
Is supported by the head 22 of the head. In addition, it is possible to extend the unit 23 on the opposite side of the arm 12 and engage with the stopper moving amount sensor 24 attached to the outer wall of the tandem 2 to measure and grasp the relative positional relationship between the pouring nozzle 3 and the stopper 4. it can. Further, a method of pouring control will be described with reference to FIGS. 3 and 4. The pouring control panel 25, which has received the pouring control signal b from the integrated control device (not shown) of the equipment, first operates the valve 26 by the signal b to operate the cylinder 21 to open the stopper 4 upward. At the same time, the motor 14 is driven by the signal C via the motor driver 27 to operate the stopper 4 in a direction to close downward. When each operation is completed, the pouring nozzle 3 is closed by the stopper 4, and the cylinder 21 is at the position where the full stroke has been raised (opening direction), and the pouring is ready. When the pouring start signal is received at t (t 2 ), the motor 14 is driven at the predetermined opening speed to open the stop α of the stopper 4.
(T 3 ), the molten metal 1 is discharged to the slit nozzle 6, and is held at that position for the time required until the space 7 is filled (until t 4 ). The stopper is opened up to the pouring opening β (t 5 ). By this operation, the molten metal is ejected from the slit nozzle 6 toward the cooling roll 8 to start forming a metal sheet, and the metal sheet 9 is continuously manufactured by being continuously poured. During this time, it is assumed that the amount of the molten metal 1 in the tank 2 is replenished from another container in an amount corresponding to the discharged amount, and a constant amount is always secured. The opening α of the stopper 4 and the steady pouring opening β are detected by the sensor 24, are compared with the command value by the signal d, and are closed-loop controlled so as to match the command value of the pouring control device 25. As described above, when the continuous production winding for one unit is completed as described above, the next winding must be performed without a break, but for this purpose, it is necessary to instantaneously interrupt the metal sheet. Becomes Therefore, for continuous pouring, the screw-side opening is set to 0 (that is, the stopper opening is 0) while maintaining the steady pouring opening β.
After the operation (t 6 ), a predetermined time (t 6 to t 7 ) (for example,
0.1~0.5Sec) Later, by increasing the cylinder stroke again to full stroke, a stop opening also maintains a steady pouring opening beta, production of sheet metal in the same pouring criteria and t 6 previous situation And the formed metal sheet is subjected to the second winding. By repeating the same operations as the third, fourth, etc. in this manner, it is possible to manufacture a large number of metal sheets while continuously supplying the molten metal. Here, the relationship between the stroke on the cylinder side and the stroke on the screw side is determined so as to satisfy the relationship of “cylinder 100% stroke> screw 100% stroke”. Is guaranteed. According to the present embodiment, after the space 7 of the slit nozzle 6 is smoothly filled with the molten metal at the start of pouring, pouring is started to form a sound metal sheet tip and a steady part following it. In addition, a large number of metal sheets can be manufactured by dividing a multi-unit molten metal into winding units. [Effects of the Invention] According to the pouring control device of the molten metal quenching equipment of the present invention, a multi-unit molten metal is continuously cast, a large number of thin metal sheets are continuously produced, and a good quality is obtained even at the start of pouring. It is an object of the present invention to provide a pouring control device for a molten metal quenching facility that can form a front end portion of a metal sheet having a sound shape and can form a steady portion following the front end portion of the metal sheet.
