采煤机截齿是由不同的材料构成的,截齿的性质也是由不同的材料性质决定的,只有选择正确的材料,才能保证采煤机截齿的质量。完成截齿的选材工作后,则进入了采煤机截齿的加工制造阶段,这项工作对截齿制造的工艺有着较高的要求。本文分析了采煤机截齿的失效形式以及加工需注意的问题,介绍了截齿材料的种类以及特性,并对截齿的制造工艺进行了叙述,希望可以为提高采煤机截齿的质量,延长采煤机使用寿命提供帮助。
Shearer pick is composed of different materials, the nature of the pick is also determined by the nature of different materials, only the correct choice of materials, in order to ensure the quality of shearer picks. After the completion of the selection of picks, then into the Shearer pick processing and manufacturing phase, this work on the manufacturing technology of picks have higher requirements. In this paper, the failure modes of shearer picks and the problems needing attention are analyzed. The types and characteristics of picks materials are introduced. The manufacture technology of picks is also described. It is hoped that this method can improve the quality of shearer picks , To extend the life of the shearer to provide help.
