摘　　要：通过对进口液压支架连接头的材质化学成分、金相组织分析、力学性能的测定,依据国内情况研究开发了液压支架连接头用新材质。经过铸造试棒以及零件试制,热处理试验、检测、对比、型式试验,最后取得了可靠数据,并确定合理的工艺参数。在矿山井下现场批量使用,效果良好,满足设计要求。The new material is developed and produced, through chemistry composition analysis, metallography analysis and mechanical property measuring of the materials used in manufacturing the imported powered support connector. Have made some technology tests such as casting test bars, parts trial -produce and heat treatment, finally have got reliable data and confirmed reasonable technology parameters by testing and contrasting. They have been used in batch at underground mines, and got effective result and meet the design requirements.
