摘要
介绍了采用硅热法回收高速钢磨屑中的W.Mo.Cr.V并冶炼再生合金基料的原理及工艺过程,对原料粒度、还原剂、石灰及单位热效应对回收率的影响进行了分析研究。研究结果表明:采用硅热法回收工艺是可行的WMo回收率在95%以上,Cr回收率大于55%,V质回收率不低于20%。冶炼出的产品量稳定,可满足炼钢使用要求。充分做到了废物利用,具有明显的经济效益和社会效益。
The principle and process to recover W, Mo, Cr and V in H.S.S. abrasive dust with silicon-thermal method and produce regenerated alloy base material are introduced. The effect of raw material grain size, reducing agent, lime and unit thermal effect on recovery ratio is analyzed. It is showed from the results that the process is feasible, the recovery ratio of W and Mo is more than 95 percent, of Cr over 55 percent, of V no less than 20 percent. The quality of product is stable and can meet the demands for steelmaking. The waste of tool abrasive dust is fully used and remarkable social and economic benefit achieved.
