过去,我厂采用氧乙炔焊接法生产钢管,工艺落后,劳动强度大,产量低,质量差。为了迅速摆脱落后的生产面貌,我厂自制成功100kw 小型高频焊管机组。100kw 小型高频焊管机组是参照从西德引进的φ32机组,通过对上海自行车厂、上海自行车三厂和上海延安钢管厂等使用单位调查,作了改进、提高,该机组投产以来,电气与视械部分运转都很正常,产量、质量达到要求。目前,可以加工制造吹氧钢管、电线套管、家具钢管、自行车钢管以及0.7毫米厚的阳伞管(表一),产量三班可达3000吨左右。
In the past, our factory used oxygen acetylene welding production of steel pipe, backward technology, labor-intensive, low output, poor quality. In order to quickly get rid of the backward production outlook, I successfully made 100kw small high-frequency welded pipe unit. 100kw small high-frequency welded pipe unit is a reference to the φ32 unit imported from West Germany, through the Shanghai Bicycle Factory, Shanghai Bicycle Factory and Shanghai Yan’an Steel Works and other units using surveys, made improvements to improve the unit put into operation since the electrical and visual Mechanical part of the operation are normal, yield, quality requirements. At present, it is possible to process and manufacture the oxygen-blown steel pipe, the electric wire casing, the furniture steel pipe, the bicycle steel pipe and the 0.7 mm thick parasol pipe (Table 1). The output can reach about 3,000 tons in three shifts.
