    During continuous casting, in order to avoid a cessation of the casting operation which is caused by a narrowing of the flow channel of a tundish equipped with a sliding gate, two processes are utilized. A first process enables an automatic rinsing so as to flush away any obstructions causing the narrowing, and, if the rinsing process is unsuccessful, a second process is effected in which the obstructions are manually removed by an operator.

    The invention relates to methyl iron.
    The purpose of the invention is to improve the quality of the ingot.
    The drawing shows a block diagram of an apparatus for carrying out the inventive method, with a slide gate being in the throttling position.
    The device contains an intermediate ladle 1 with a metal melt and a gate valve 2, Kotopb regulates the flow of melt from the ladle through a common flow channel 3 through the injection pipe 4 into the mold 5. For this, the movable gate plate 6 is mechanically connected to the actuator 7, whose working position is determined 8 gauge position. Cast pipe 4 enters its
    the free end to the mold 5: Position 9 indicates the level of the melt, in which, during normal casting, there is approximately 80% of the level measuring section 10, which consists of the transmitter 11 and the measuring receiver 12. The ingot 13 is pulled out by the drive rollers 14 with 15 s controller 16. Next, the driver 15 has a meter 17 drawing speed, which is connected to the controller 16 and the processor 18, which, in addition, receives and processes information meter 8 position and the measuring receiver 12. Integral The control unit 19 implemented with the processor 18 transmits the corresponding control commands to the actuator 7 of the slide gate 2 and to the controller 16.

    Since the drawdown rate for the normal continuous casting process is set constant, only the normal level 9 in the mold 5 is controlled from the inflow side by means of the slide gate 2. For this, the slide plate 6 occupies the throttling position, which allows the slide gate to regulate the metal consumption, to maintain a balance between the flow rate of the melt and the ingot drawn from the mold. On the one hand, the plate 6 of the gate moves to closing, for example, when the passage opening is enlarged due to wear, and on the other hand,

    However, the plate moves to increase the passage as soon as the cross section narrows, for example, due to oxide deposits or freezing of the metal. Such constrictions become a problem, since the opening of the slide gate 2 ends when it is fully open, if the melt flow rate required by the current level of the metal in the mold 5 is no longer provided by the narrowed section.
    In order to first avoid the reduction in the rate of the ingot drawdown required, block 19, when 90% of the fully open state is reached, switches the gate to the closing position, so that the actual level 9 of the melt in the crystallizer decreases and a space is formed to the specified level 9. If, for example, the actual level reached the height of level 20 in the measurement area 10,
    Then, the executive unit 7 receives a command to fully open the slide gate 2 in order to obtain a powerful melt wave from the flow channel 3, which in this case is freed from constrictions. The increased melt flow rate entering the mold fills the specified artificially created cavity and raises the actual level to a predetermined level with the transition to the normal continuous mode.
