ABSTRACT:
A method for melting machine chips characterized by a preheating zone, a prereducer zone, and a melting zone the latter of which is heated by an arc heater through which a reducing inert gas is introduced into the communicating zones, whereby metal chips entering the preheating zone move through the subsequent zones in counterflow to the reducing gas flow.
