提高锻钎工作质量、保证钎子供应及时,是降低鑿岩成本、提高鑿岩效率的重要途径。第一锡矿松树脚矿在改造锻钎工作中充分发挥了锻钎机的效能,自每班生产60根提高到134根,改用聚热炉烧钎,掌握了淬火和冷却的适宜方法,使钎子的掉角、裂纹现象大大减少,提高了钎子质量,取得了很大的成绩,是值得其他各矿学习的。但是,该矿锻钎工作中还存在以下问题,希该矿和其他各单位进一步研究解决。一、锻钎所用燃料按照採矿规程规定不放纯用焦炭,而应配以70％木炭。二、根据热处理理论,可採用快速加热法加热,这样也不会使制件发生裂纹。
Improve the quality of forging work, to ensure timely supply of brazing is to reduce the cost of drilling, an important way to improve the efficiency of drilling. The first tin ore pine footing in the transformation of forging work to give full play to the effectiveness of forging brazing machine, from the production of 60 per class to 134, switch to the use of brazing furnace, the quenching and cooling to master the appropriate method, So that the brazing angle of the child, greatly reduce the crack phenomenon, improve the quality of the solder, has made great achievements, it is worth learning from other mines. However, the mine forging work there are still the following problems, Xi iron ore and other units to further study and solve. First, forging brazing fuel used in accordance with the provisions of the mining regulations with pure coke, but should be accompanied by 70% charcoal. Second, according to the theory of heat treatment, rapid heating can be used to heat, it will not crack parts.
