Abstract

1. Способ автоматического управления машиной непрерывного литья заготовок, включающий регулирование уровня металла в кристаллизаторе путем изменения расхода металла из промежуточного ковша, отличающийся тем, что, с целью повышения производительности разливки, уровень металла регулируют в зависимости от величины деформации корочки слитка в точке, лежащей посредине между кристаллизатором и первым поддерживающим роликом зоны вторичного охлаждения, причем при величине деформации, равной 0,05 - 0,08 расстояния между кристаллизатором и осью первого поддерживающего ролика, уровень металла повышают, а при иной деформации уровень металла снижают.2. Устройство для автоматического управления машиной непрерывного литья заготовок, содержащее задатчик постоянного сигнала, соединенный с первым входом первого блока сравнения, а также последовательно соединенные датчик уровня металла, преобразователь, второй блок сравнения, регулятор расхода металла из промежуточного ковша и исполнительный механизм привода стопора, отличающееся тем, что, с целью повышения производительности разливки, оно дополнительно содержит датчик деформации корочки слитка, расположенный посредине между кристаллизатором и первым поддерживающим роликом, соединенный со вторым входом первого блока сравнения, и триггер Шмидта, вход которого соединен с выходом первого блока сравнения, а выход - со вторым входом второго блока сравнения.1. A method for automatically controlling a continuous casting machine for billets, including adjusting the metal level in the mold by changing the metal consumption from the tundish, characterized in that, in order to improve casting performance, the metal level is adjusted depending on the deformation value of the ingot crust at the point in the middle between the mold and the first supporting roller of the secondary cooling zone, moreover, with a strain value of 0.05 - 0.08, the distance between the mold and the axis n The first support roller, the metal level is increased, and with a different deformation the metal level is reduced. A device for automatic control of a continuous casting machine containing a constant signal adjuster connected to the first input of the first comparison unit, as well as series-connected metal level sensor, transducer, second reference unit, metal regulator of the tundish and actuator of the stopper actuator, different that, in order to improve casting performance, it additionally contains an ingot crust deformation sensor located in the middle between the crystal an isolator and a first support roller connected to the second input of the first comparison unit, and a Schmidt trigger, the input of which is connected to the output of the first comparison unit and the output to the second input of the second comparison unit.
