我厂所用FN_1—150—1型和FN_1—150—2型缝焊机的电极,材料为QCr0.5—0.2—0.1(含Cr0.4～1.0％,Al0.1～0.25％,Mg0.1～0.25％,其余为Cu,[1],相当于苏联牌号Mц4[2]),历来外购,价昂且来源困难。由于缝焊机结构本身的限制,电极只能用到外径φ120～φ130mm,就分解改作点焊电极或作废铜处理。为了节省昂贵的电极和缓和材料来源的困难,我们作了重熔回用试验。具体做
The electrodes of FN_1-150-1 and FN_1-150-2 seam welder used in our factory are made of QCr0.5-0.2-0.1 (containing Cr0.4 ~ 1.0%, Al0.1 ~ 0.25%, Mg0.1 ~ 0.25%, the rest is Cu, [1], equivalent to the Soviet Union brand Mц4 [2]), traditionally purchased, expensive and difficult source. Due to the structure of the seam welder itself, the electrode can only be used outside diameter φ120 ~ φ130mm, to break down into spot welding electrodes or scrap copper treatment. In order to save expensive electrodes and ease the source of the material difficulties, we made remelting reuse test. Specific to do
