Abstract
This paper briefly describes the current technologies of removing lead from lead brass at home and abroad.Based on the theoretical analysis of compound separation method,it was inferred that Ca element had the potential of removing lead.The effects of Si-Ca and Mg-Ca on removing lead and properties of alloys without lead were summarized.The lead removal rate of brass melt reached 83% with Si-Ca as deleading agent and the Si content in brass substrate after deleading exceeds the limit;the lead removal rate of brass melt reached 77.3% with Mg-Ca as deleading agent and Mg added to the substrate reacts with Cu and generated metal compound Cu2 Mg,which possessed the ability of lubricating and chip-breaking similar to free lead in the process of cutting and removed lead from lead brass and developed a kind of brass that was environmental-friendly and easy-to-cut.关键词
