本刊讯利用爆炸硬化方法提高矿用高锰钢件(电铲铲齿,破碎机衬套和球磨机衬板)使用寿命的应用研究取得成功,最近通过部级技术鉴定。冶金工业部于lg88年5月28—29日在首钢矿山公司召开了矿用高锰钢件爆炸硬化技术鉴定会推广会,来自24个单位59名代表参加了会议。为了提高矿山大量应用的高锰钢件的使用寿命,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承担矿用高锰钢件爆炸硬化提高使用寿命的应用研究。自1987年3月开始,在首钢矿山公司、鞍钢矿山研究所进行了WK-4型电铲铲齿
The Journal of explosion hardening method to improve mining high manganese steel parts (shovel shovel shredder bushing and ball mill liner) of the successful application of the research success, recently passed ministerial level technical appraisal. The Ministry of Metallurgical Industry held a promotion meeting of blasting and hardening technology for mining high manganese steel parts at Shougang Mining Company from May 28-29, l999, and 59 representatives from 24 units attended the meeting. In order to improve the service life of high-manganese steel parts used in a large number of mines, Shougang Mining Company, Anshan Iron Mines Institute and Institute of Mechanics, Chinese Academy of Sciences jointly assume the research on application of high-manganese mine steel parts for explosion hardening to improve service life. Since March 1987, the Shougang Mining Company and the Ansteel Mine Research Institute have carried out the WK-4 shovel shovel tooth
