ABSTRACT:
A press for compacting scrap metal for subsequent melting, e.g. in an electric furnace, the press comprising a supporting bed, a chamber formed in the bed and open at the top for the introduction of scraps thereinto, a closing cover for the chamber lockable in a closed portion by locking means. Movable and stationary walls define the sides of the chamber and are associated with the bed. Control and guide means for the shifting movement of the movable walls are adapted to bring the movable walls close to each other until there is defined therebetween a cavity. The distances between the walls are smaller than and proximate the distance between the inner walls of the furnace whereinto the compacted scraps are to be molten. A ram with related control means defines with its active face the base of the cavity and is movable in the bed to and away from the cover in order to press, against the cover, the scraps already compacted in the cavity. The active face of the ram has a cup-like configuration with a bottom and lateral walls surrounding the bottom and projecting towards the press cavity. In the rest position the bottom of the ram active face lies below the bottom surface of the press chamber.
