钎杆是采矿的重要工具之一,它的使用寿命长短,直接影响矿山的建设。文化大革命前,我国主要靠进口钎杆和成品钎。在毛主席“独立自主,自力更生”的指示指引下,冶金部钎杆技术工作队,根据我国自然资源的实际情况,研制了适应于制造22毫米小钎杆的新钢种,自己生产钢钎。但是钢钎的使用寿命一直不稳定,特别在锻造领盘时形成的喇叭孔,在以后整形过程中,无法消除,极大影响着钎杆的寿命。为此,广东工学院锻压专业部分师生到新抚钢厂钎子钢车间进行领盘工艺的试验研究。经过三个多月的试验,找出钎子钢领盘出现喇叭口的原因,重新制定工艺,初步解决了长期未解
Rod is one of the important tools of mining, its service life, a direct impact on the construction of mines. Before the Cultural Revolution, China mainly imported rods and finished products brazing. Guided by Chairman Mao’s guideline of “independence and self-reliance,” the Task Force on Brazing Rod Technology of the Ministry of Metallurgy developed a new type of steel suitable for the manufacture of small 22-mm brazing rods and produced its own brazing steel according to the actual conditions in China’s natural resources. However, the service life of the steel rod has been unstable, especially in the forging of the speaker formed when the hole in the plastic process in the future, can not be eliminated, greatly affecting the life of the drill rod. To this end, Guangdong Polytechnic forging part of the professional teachers and students to the new plant steel plant Magnesium Welds pilot process of the pilot study. After more than three months of experimentation, find out the reason why the trumpet steel bell plate has a bell mouth, re-establish the process, and initially solve the long-term unsolved
