本文论述了用不同配比的稀土、稀土复合剂对ZG35CrMo钢进行变质处理,从而确定了一种最佳稀土-硅钙复合变质剂,采用这种复合变质剂处理的ZG35CrMo钢,具有较高的综合性能,它克服了一般低合金钢所具有的裂纹倾向大的缺点,使这种钢的铸造性能优于普通碳素钢,除用于砂模铸造外,还可用于铁模铸造。对该钢采用稀土-硅钙复合剂比单独采用稀土处理能获得更明显的效果。
In this paper, ZG35CrMo steel was treated with different proportions of rare earths and rare earth compounds to degrade the ZG35CrMo steel, so as to determine one of the best RE-Si-Ca composite degenerators. The ZG35CrMo steel treated with this compound modifier has high Comprehensive performance, it overcomes the general low alloy steel has the disadvantage of the tendency of cracks, so that the cast steel performance superior to ordinary carbon steel, in addition to sand casting, but also for iron casting. The use of rare earth steel - calcium silicate composite than the rare earth treatment alone to obtain more significant results.
