研究了国外煤矿机械重负荷齿轮用钢及其加工工艺,并和国产重负荷齿轮钢做了性能对比,找到了可替代国外煤矿机械重负荷齿轮用钢,降低了煤矿机械制造成本。
The foreign coal mine machinery heavy duty gear steel and its processing technology are studied. Compared with the domestic heavy duty gear steel, the performance comparison is made and the steel used for replacing the heavy duty gear of the foreign coal mine machinery is found to reduce the manufacturing cost of the coal mine machinery.
