Abstract

PURPOSE: To prevent the occurrence of backlash and improve ingot quality by unbalancing the load allotment of pinch rolls through controlling of the field currents of motors thereby eliminating zero torque cross.
CONSTITUTION: Pinch roll motors 100AW100F are connected to a thyristor gate circuit 101 via a power source 103. This is accomplished by thyristor gate controlling by the output signal of a speed control device 102. The signal of the pilot generator 106 of the motor 100F inputs to the device 102 and the gate signal of the circuit 101 is created by the signal of a speed commander 105. On the other hand, the output signal of a current detector 104 inputs to an AND circuit 107. The signal of casting drawing is inputted from the A terminal to the AND circuit 107 and the motor load unbalance control signal is inputted thereto from the B terminal. When the signal of the terminals A, B and the current detector 104 are inputted to the AND circuit 107, a relay 108 is operated, whereby the load unblance control is released.
