我矿钢焊未经热处理前,在凿岩过程中,焊子中断率很高。这样大大降低了纯凿岩时间,对工人也极不安全。经我矿工人建议使用退火热处理,获得了解决。1.处理过程:加热方法,钢焊加热时,一定要使钢焊各部温度均匀。加热到一定温度以后,要徐徐进行,并使焊子转动一下,使焊子受热均匀在炉子内要保持有还原性气体 CO,使其不受氧化,退火温度在760°～850℃之间。
My mine steel without heat treatment prior to drilling process, the solder break rate is high. This greatly reduces the pure drilling time, is also very insecure to the workers. After miners suggested using annealing heat treatment, was solved. 1. Process: heating method, steel welding heating, the temperature must be uniform so that the Department of steel welding. After heating to a certain temperature, to be carried out slowly, and make the welding torch rotate so that the welding torch is heated evenly in the furnace to maintain a reducing gas CO, so that it is not oxidized, annealing temperature between 760 ° ~ 850 ℃.
