介绍了采煤机摇臂壳体材料对采煤机摇臂结构及整机性能的影响,通过对国外采煤机摇臂壳体材料进行成分分析、硬度分析和金相分析,比较了国内外壳体材料性能的优缺点,为国内采煤机摇臂结构形状优化及整机稳定性的提高提供了一定的参考。
The influence of shearer shell material on the rocker arm structure and overall performance of the shearer is introduced. The composition, hardness and metallographic analysis of the shearer shell material of shearer are introduced. The advantages and disadvantages of the material properties provide some references for the optimization of the rocker arm shape and the stability of the complete machine in the domestic shearer.
