Investigation and Application of High Silicon Abrasion Resistant Cast Steel Hammers
A new high silicon cast steel hammer whose main composition was inexpensive silicon alloy was designed to overcome the shortcomings of high manganese steel, white cast iron and low alloy cast steel. High manganese steel hamper had low hardness and poor working-hardening, white cast iron hammer had low toughness and was easy to fracture and low alloy cast steel hamper had low hardenability. The manufacture process of high silicon cast steel hammer was particularly introduced. The filtrating process of motel steel, pre-quenching treatment and compound heat treatment that used to improve hardenability were thorough investigated. The servicing property of high silicon cast steel hammer is more excellent than that of traditional hammer materials. When high silicon cast steel hammer is used, the production rate of crusher can increase, and the crushing cost of raw material decreases. There is a good economic benefit.
