ABSTRACT:
A melt rate control system for consumable electrode remelting uses a closed loop control system to control electrical power and hence the electrode melt rate. The control equation is purposely adjusted to cause the melt rate to initially exceed the steady state melt rate in a controlled manner to take advantage of the higher permissible melt rate at the bottom of an ingot. Initially, the melting current is held at a steady level sufficiently high to cause the melt rate to exceed the steady state melt rate. The initial current is then reduced in a controlled manner to bring the melt rate to the steady state condition. The length of time and amount of excessive melt rate is matched to the higher permissible melt rate at the bottom of an ingot.
