Abstract
A method for preparing scrap metal charges to be loaded into a smelting furnace comprises filling a loading container in stages with loose scrap metal and carrying the container on a carriage into a press for compressing the scrap metal directly in the container to a preset density. The compressed scrap metal is charged into the furnace directly from the container. An apparatus for this method comprises a gate press having rails for the carriage and a press die suitable for compressing the scrap metal as arranged in the container. The carriage can be adapted to receive containers of different diameter and the press die can be fitted with a detachable ring to increase the die area for compression.
Claims6
An apparatus for preparing scrap metal charges for smelting furnaces, comprising a press having a fixed press bed and a vertically movable press die, rails arranged adjacent and in said press, said rails having rail sections arranged below said press die, a carriage having wheels movable on said rails and rail sections into a position below said press die, a container for scrap metal to be compressed by said press die, said container being removably supported by said carriage and having cross dimensions substantially corresponding to the cross dimensions of said press die for allowing said press die to compact scrap metal in said container, and further comprising means for lowering said rail sections during the pressing operation, wherein said carriage has a carriage base frame and said press bed has a beam structure for supporting said carriage base frame when said rail sections have been lowered and the scrap metal is compressed by said press die.
