摘　　要：通过对消失模铸造钢爪生产工艺的改进,采用顶注式,配以在钢爪两臂与爪交界处设置暗冒口的工艺,不仅简化了铣工序的复杂性,提高了生产效率,而且还降低了生产成本,提高了企业的经济效益和市场竞争力。Production process of lost foam casting steel claw was modified including adopting top pouring and setting blind riser at interfacial position of two arms with claw of the steel claw,which not only simplifyied the complex milling process and increased product efficiency but also decreased product cost and enhanced economic profit and market competition.Meanwhile,the technology could meet the requirements of save-energy and environmental protection for foundry trade.The practical production verifies the feasibility of the method.
