龙烟铁矿利用旧电焊接机焊接短尺钢釬子,对克服钢釬使用上的浪费,提出了一项新的经验。1.焊接方法:(1)釬子钢回收后,先将中空眼用风吹通,并调直弯度。(2)接口两端用砂轮磨去污锈,并磨正接口。(3)焊接时先将两接口六方楞角对正,再用风吹通,并吹出铁渣,然后进行焊接。(4)焊接时电流量要掌握准确,一般是3～4个字,不宜过高,并须保持机温70℃,温度过高则易烧毁变压器,为防止接口断裂,给风不宜过猛。
Longyan iron ore welding using the old electric short-cut steel brazing son, to overcome the use of waste on the use of brazing, put forward a new experience. 1. Welding method: (1) after the recovery of the brazing steel, the hollow eye is blown through the wind and the straightness is adjusted. (2) both ends of the interface with a grinding wheel to remove rust, and grinding positive interface. (3) When welding the two interface first six Leng Leng angle alignment, and then blowing through the wind, and blowing iron slag, and then welding. (4) When welding, the current should be accurate, usually 3 ~ 4 words, not too high, and to maintain the machine temperature 70 ℃, the temperature is too easy to burn transformers, to prevent the interface fracture, the wind should not be too much.
