【摘要】：凿岩钎钢钎具是传统钨工业的重要应用领域。总结了中国钎钢钎具产业的发展和现状,重点介绍了锥体连接钎头、硬质合金整体钎和凿岩钻车用中大直径螺纹连接钎头的特点,并分析了各系列产品应用中的问题,提出了钎头重磨再用和废旧硬质合金钎头残留刃齿回收利用方面的建议,并重点推荐了"一步法"生产硬质合金的新工艺。文章指出了当前我国钎钢钎具行业的进一步发展,急需解决钎具使用技术及配套机具研发相对滞后,以及废旧硬质合金片齿的回收利用等问题。
[Abstract]:Rock drilling steel drill tool is an important application field of traditional tungsten industry. The development and present situation of Chinese drill steel drill tool industry are summarized, and the cone joint bit is introduced emphatically. The characteristics of medium and large diameter thread connecting bit for cemented carbide integral drill and rock drilling vehicle are analyzed, and the problems in the application of each series of products are analyzed. Some suggestions on the regrinding and reusing of the bit and the recovery of the residual edge teeth of the waste cemented carbide bit are put forward. The new technology of producing cemented carbide by one-step method is recommended emphatically. The article points out that the further development of brazed steel and drill tool industry in our country at present, it is urgent to solve the problem that the application technology of drill tool and the research and development of supporting machine tool are lagging behind. And the recycling of scrap cemented carbide teeth and so on.
