ABSTRACT:
An improved drop hammer or slag breaker is disclosed for use with cranes equipped with electromagnets. The breaker combines a working end made of a specially shaped manganese steel body, which is non-magnetic, with a rounded magnetic metal lifting end or head made of high strength wear resistant steel. The extremely tough manganese steel body is secured to the head by wedges forced through head lug openings and adjacent openings in the body portion. Bolted slidable keepers connected to the head retain the wedges tightly in place. The device is particularly useful for breaking up iron or steel furnace slag into smaller pieces and into magnetic and nonmagnetic pieces, the former of which can then be separated and removed by the crane's magnet. Increased wear performance is afforded by the cast manganese steel body. Increased breaking performance is gained by use of the specially shaped body and/or body working end.
