用蠕墨铸铁制造齿轮的试验研究

本文叙述了用Mg—Ti—Ca—Re—Si—Fe单一合金作蠕化剂,用冲天炉铁水制造纺织机齿轮的试验研究工作。试验结果表明,蠕铁齿轮达到了设计者对机械性能的要求,不要热处理,切削加工性能好,废品率低。

An Expermental Research on the production of Compacted Graphite Cast Iron Geas

Using Mg-Ti-Ca-Re-Si-Fe single alloy as a modifying agent, the experimental work for producing compacted graphite cast iron gears with cupola melting iron is described. Produced gears have reached the mechanical properties required by the designer. They need not be heat-treated, have good machinability and very low reject rate.
