ABSTRACT:
Control system for electroslag remelting having a block for recording arc discharges, the input of which is connected to the current-carrying bus bar of a crystallization mold, while its output is connected to a block for switching over the rate of electrode feed, to the second input of which there is connected the output of a presetting block, and the output of the block for switching over the rate of feed of the electrode is connected via a regulator to an actuating mechanism. The current-carrying bus bar is connected to a block for recording the rectifier valve effect, the output of which is connected via a block for operation switch-over to a third input of the block for switching-over the rate of electrode feed.
