1979年上海钢铁研究所首先在6吨钢包实现深喷取得成效,1980年初与上钢三厂合作,建立了转炉30吨钢包的简易喷粉装置,其后两单位又进一步合作,于1982年6月在电炉车间建成了22吨级带有自动顺序控制的钢包喷粉装置。经喷吹120炉,设备运转正常,输送稳定。对16MnR、50CrVA 两个重 In 1979, Shanghai Iron and Steel Institute firstly achieved the effect of deep-spray in 6 tons of ladle. At the beginning of 1980, it cooperated with No. 3 Steel Plant and established a simple dusting device of 30-ton ladle. Afterwards, the two units further cooperated. In 1982, Month 22-ton ladle dusting device with automatic sequence control was built in the electric furnace plant. After blowing 120 furnaces, the equipment is operating normally and the transportation is stable. For 16MnR, 50CrVA two weight
