目前在我国矿山所使用的各种耐磨件,主要是高锰钢材质。为了提高其使用寿命,降低消耗,由首钢矿山公司、鞍钢矿山研究所和中国科学院力学研究所共同进行的矿用高锰钢件爆炸硬化工艺的应用研究已取得成功。对WK-4型电铲铲齿,粗、细碎机衬板和球磨机衬板进行的试验和使用表明,采用厚为4cm的板状炸药进行高锰钢件的爆炸硬化处
At present, all kinds of wear parts used in mines in our country are mainly made of high manganese steel. In order to improve its service life and reduce the consumption, the research and application of blasting and hardening technology for mining high manganese steel parts jointly undertaken by Shougang Mining Company, Anshan Iron and Steel Research Institute and Chinese Academy of Sciences Institute of Mechanics have been successful. The test and use of the WK-4 shovel shovel tooth, coarse, fine liners and ball mill liners showed that the explosive hardening of the high manganese steel pieces was carried out using plate-shaped explosives having a thickness of 4 cm
