炮钎是矿山钻眼、凿岩不可缺少的工具之一。它在掘进,采矿中是主要消耗材料,直接影响着巷道成本、进度,是目前凿岩设备中最薄弱的环节。在不同硬度的岩层中,炮钎折断的现象也特别严重。为延长钎子寿命,该厂对55SiMnMo炮钎进行了钎子整体回火与复回火的热处理工艺试验,利用空压机的废机,柴油混合,给空心钢钎子进行整体回火和二次回火的热处理工艺。在试验中总结出对本单位加工的钎子进行回火、使用、再回火、再使用。对外厂或进口的成品钎子进行使用、回火、再使用两种方
Gun drill is mine drilling, drilling one of the indispensable tools. It is in driving, mining is the main consumption of materials, directly affect the cost of the roadway, the progress is the weakest link in the current drilling equipment. In different rock formations, the phenomenon of gun drill broken is particularly serious. In order to extend the life of the brazing alloy, the factory carried out the heat treatment process test on the 55SiMnMo gun braze for the overall tempering and complex tempering of the brazing alloy. By using the waste air compressor and diesel oil mixture, Secondary tempering heat treatment process. In the experiment concluded that the processing of the unit of the solder tempering, use, and then tempering, and then use. To the factory or imported finished product, the use of solder, tempering, and then use two parties
