Abstract
PURPOSE: To perform titled foreseeing and prevent breakout by subtracting the elastic force of an oscillation transmission mechanism from the intertia force of a mold, calculating the frictional force between the mold and an ingot and comparing the same with a set value.
CONSTITUTION: The speed acceleration signal of an acceleration detecting end 24 which is secured to one end of a mold 13 and detects the accelerations in the vertical directions of the mold 13 is inputted via an amplifier 25 to an arithmetic unit 30. The rates of elastic deformation of an oscillation transmission mechanism are detected with differential transformers 26, 28, and are inputted via amplifiers 27, 29 to the unit 30. In the unit 30, inertia force is determined by multiplying the acceleration of the mold by the mass of the mold, and elastic force is determined by multiplying the rates of elastic deformation by the spring constant of the oscillation transsion mechanism. From the difference therebetween, the frictional force acting between the mold 13 and the ingot is determined, and in a comparator 32, it is compared with the set value determined by the kind of steel and the size of the mold. When it exceeds the set value, an alarm emitting device 32 emits an alarm.
