ABSTRACT:
A columnar stream of scrap particles having about 15-25 percent full density, is electrically inductively heated in a reducing atmosphere while being laterally confined by walls which are not made so hot as to become tacky or adhere to the confined column of scrap particles. The heated stream is laterally squeezed to increase its density to about 40-50 percent full density and is pulled downwards, out of extensive confinement by such walls. It is then inductively heated in a reducing atmosphere to a higher temperature than in the prior induction heating step, and squeezed to a greater extent, sufficiently to form a fully dense layer about the whole of the outer peripheral surface of the stream. By preference, insufficient heat and/or pressure are used to condense the stream to a fully dense condition right to its core. If this stream does not continue directly into another continuous process, it is severed into a succession of billets each end of which is sealed to prevent internal oxidation of the billets.
