Title: Novel apparatus and solid state method for converting small pieces of metal to a workpiece

Abstract: A method of converting scrap or other small pieces of metal into a useful, commercial product while maintaining the metal in a solid state. According to the process, the pieces are maintained together for further processing. They are impacted, while heated, to produce a metal body and thereafter subjected to continued impaction so that the pieces forming the body are welded together into a cohesive, homogeneous slab. There is also disclosure of a novel press and method of operating the press. The press is of the harmonic type. Its novel aspects include control of movement of novel platens during rotation of shafts which drive the platens and perimetral constraint of a workpiece being forged to achieve rapid impaction and self feed of a workpiece. There is also disclosure of a novel method for making flakes of steel, a novel furnace including seals for maintaining the furnace gas-tight, a novel method in which the pieces of metal are scrap steel and baled together into a bale in which the scrap pieces of random size and shape become intertwined together and novel processes and apparatus for cleaning scrap or other metal pieces.
