| 摘 要： | 通过对国产与瑞典产液压凿岩钻车用钎杆的化学成分、渗碳硬度以及金相组织等分析,初步认定两种产品在材质和生产工艺上存在差异。认为在冶炼时提高钢的纯净度,在中空钢材生产时进行轧制与冷却控制,在制钎过程中进一步优化热处理工艺,将会改善钢材的组织状况,优化钎杆的综合机械性能,提高凿岩进尺的寿命。

| Abstract: | After analyzing homemade and Sweden-made drill rods for hydraulic rock drills in their chemical composition,carburization hardness and microstructure,it was confirmed that the two drill rods were different in material and manufacturing technology.It was considered that enhancement of steel purity in the process of smelting,control of rolling and cooling process during producing hollow steel as well as further optimization of heat treatment in the process of producing drill rods would improve the steel micro... |
