采煤机大型焊接结构件的研究

The research on the large welding part of shearer

针对大功率综采采煤机主机身传统的铸造结构 ,提出了用铸焊、锻焊结合的焊接结构替代铸造结构 ,进行了可行性、经济性、合理性分析 ,并从工艺、设计角度作了进一步说明。

This essay advances the new idea of combining casting with welding as to the casting structure of high_powered shearer's main body.It carries out the feasibility and economy study,and further illustractes it from the design and craft.
