钎子鋼不僅是主要凿岩工具之一,其消耗量的多少又是决定鑿岩成本高低的主要因素。第三銅鑛1954全年共損耗用钎子鋼38噸,平均每天都有150～200公斤钎子鋼被折斷不能使用,这就不可避免地提高了生產成本。為了減少纤子鋼的浪費,除設法防止鑿岩斷钎外,还应該有效地利用廢钎。今年三月,本坑鍛纤工段長楊清國和工人李耀志兩同志在学習了第一鉛鋅鑛关於炭素鋼钎子接手的經驗後,根據硬質合金钎头錐孔联接的原理,結合自己工作的具体情况,製成了炭素鋼活钎头取得了良好的效果。
Drill steel is not only one of the major rock drilling tools, the amount of its consumption is the main factor in determining the cost of rock drilling. The third copper mine, 1954, consumed a total of 38 tons of brazing steel with loss of 150-200 kilograms of brazing steel per day, which could not be used. This inevitably raised the production cost. In order to reduce the waste of fiber steel, in addition to trying to prevent the drill cut off the brazing, but also the effective use of waste brazing. In March this year, two chiefs of Yangkengguo, a forging section of the forging section of the pit, and Li Yaozhi, a worker, learned about the experience of the first lead-zinc mine in taking over the carbon steel brazing rods. According to the principle of joining the brazed carbide rods and taper holes and the specific work of their own Situation, made of carbon steel drill bit has achieved good results.
