Abstract
A heat processing furnace is provided with a bifurcated feeder which allows scrap steel to be introduced to the furnace from an associated preheater, and direct reduced iron, slag formers, carburizers, and other alloys to be introduced through a lower channel in the connecting car pan directly into the furnace. The feeder is arcuate which prevents collection of molten metal and slag splash and spatter in the corners. The feeder is mounted on a connecting car, which is preferably removable and interchangeable. Apparatus for accomplishing connecting car interchangeability is also disclosed.
