高硅耐磨铸钢锤头的研究

Investigation and Application of High Silicon Abrasion Resistant Cast Steel Hammers

高锰钢锤头硬度低,加工硬化效果差,白口铸铁锤头韧性低,易断裂和低合金铸钢锤头淬透性低等缺陷,以廉价的硅合金为主要合金元素,研制了高硅耐磨铸钢锤头介绍了高硅耐磨铸钢锤头的生产制造工艺,并对锤头生产过程中的钢液过滤处理工艺,淬火预处理工艺和改善淬透性的复合热处理工艺进行了深入研究。高硅耐磨铸钢锤头的使用性能明显优于传统锤头材料,使用高硅耐磨铸钢锤头可以明显提高破碎机作业率,降低物料破碎成本,具有较好的经济效益。

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.
