煤矿采掘机械铸钢截齿研究

Research of Coal Mining Machinery steel cutter

煤矿资源是我国现代化建设无可取代的一次性能源,高产高效开采是经济建设的有力保障。对于现代化采煤,采掘机械的截齿耐磨性直接影响煤炭生产,因此采用新材料,用"铸钢"代替焊接生产采煤机截齿,合理设计截齿布置及截齿结构具有重要意义。文章通过对采掘机械截齿性能影响因素的分析,提出应用铸钢截齿的优越性,提高了截齿的可靠性,降低齿耗占吨煤成本中的比例,提高采煤机有效工作时间。

The high -efficient modernization production, so coal resources are no substitute for China＇s modernization and one-time energy, exploitation of the economic construction of effective protection. For the of coal mining, mining machinery, pick a direct impact on wear of coal the use of new materials, with the ＂cast＂ instead of welding shearer, and the design layout and cutting tooth pick structure of great significance. Based on the mining machine cutter performances for analysis, application of the superiority of cast cutter, the cutting teeth to improve the reliability of patients and reduce the cost of tooth tons of coal consumption accounted for the proportion of working time to improve the effective shearer.
