ABSTRACT:
A safe and effected method of starting up operating and shutting down a plasma fired cupola. The starting up and shutting down procedures incorporated interlocks and warning signals that insure the safety of the operators and equipment and the controls utilize the temperature of the iron in the spout as a focal point to control the torch output by separately changing field current, arc current, and torch air supply, to compensate for changes in charge make-up, particulate feed, percentage of shroud air to shroud recirculating gases to produce different irons at various melt rates.
