<p>A method and apparatus for melting metal chips characterized by a preheating zone, a pre-reducer zone, and a melting zone in conjunction with an arc heater through which a reducing or inert gas atmosphere is introduced into the communicating zones, whereby metal chips entering the preheating zone move through the preheating, pre-reducing and melting zones in counterflow to the reducing or inert gas movement.</p> |
