6LS型采煤机截齿材料和工艺的改进

Materials and Heat Treatment Process of Pick in 6LS Cong Wall Shearer

对传统的采煤机截齿材料和工艺进行优化设计 ,实际应用表明 ,用 42CrMo的亚温淬火代替3 5CrMnSi等温处理 ,不仅生产成本降低 ,而且在矿山工作条件下 。

Through optimizing design of the chemical composition and heat treatment, the actual application shows that 42CrMo sub-critical quench has low cost and a long service life and can replace 35CrMnSi.
