邯郸冶金矿山公司符山铁矿机修连电工班,针对焊接效率低,打眼用的钎头供不应求,不适应矿山生产建设飞跃发展需要,靠毛主席的哲学著作指航,发扬“自力更生,艰苦奋斗”的革命精神,经过一百五十次试验,自制成功一台六十千瓦高频焊设备。它的自制费用比同类产品造价降低三分之二,比气焊和烘炉焊接各种钎头提高效率二十八倍,还可用作机械零件淬火和小型炼钢。这台高频焊设备的主要规格数据是:
Handan Metallurgical Minerals Co., Ltd., Fu Shan Iron and Steel Company repair electrical work class, for the welding efficiency is low, drill bits used in demand, is not suitable for the rapid development of mine production and construction needs, rely on Chairman Mao’s philosophy book pointing navigation, promote “self-reliance and arduous struggle” After a hundred and fifty tests, a homemade 60kw high frequency welding equipment was successfully made. Its self-made cost lower than similar products by two-thirds, compared with gas welding and ovens welding all kinds of bit improve efficiency twenty-eight times, but also can be used as mechanical parts quenching and small steelmaking. The main specifications of this high-frequency welding equipment data is:
