采煤机截齿
采煤机截齿产品介绍
U 系列截齿是用于采煤机上的截齿,包括 U47,U62,U765,U76, U82,U84,U85,U92,U94,U95,U100,U119,U138,U170 等。
采煤机截齿可分为普通截齿,耐磨截齿,硬岩截齿,无火花截齿,超硬岩截齿和砂岩截齿。
采煤机耐磨截齿就是加耐磨层的截齿,硬岩截齿和超硬岩截齿都是用于坚硬岩上的截齿,砂岩截齿就是带有合金条的截齿,无火花截齿是用等离子激光技术在截齿上焊接一层合金耐磨层,这款最适用于瓦斯煤矿。
采煤机截齿加工工艺
42CrMo材质刀体的常规热处理工艺为:840℃油淬+360~400℃回火。 35CrMnSi材质刀体的常规热处理工艺为:880℃油淬+380~430℃回火。有条件的生产厂家也可采用880℃加热保温+280~320℃等温淬火,然后空冷的热处理工艺。
