众所周知,在苏联率先掌握不放上渣操作的,是西西伯利亚钢铁公司3号高炉。那时事先的计算表明,该操作法是不合理的,因此,该炉开炉时未立即实现不放上渣。1971年10月起,切列波威茨钢铁公司4号高炉开始才实行不放上渣操作;1973年,马格尼托哥尔斯克、下塔吉尔、新里别获克和切列波威茨钢铁公司的许多高炉都改用不放上渣操作法;七十年代末,南方的钢铁厂也采用了这种操作方法。 It is a well-known fact that in the Soviet Union, the No. 3 blast furnace of the West Siberian Iron and Steel Company was the first to hold the slag operation. The prior calculations at that time showed that this method of operation was unreasonable and therefore the slag was not immediately realized when the furnace was opened. Since October 1971, the Cherepovez Iron and Steel Company’s No. 4 blast furnace was put into operation on the blast furnace. In 1973, Magnitogorsk, Nizhny Tagil, and Clyde Waverley Many of the Steelworks blast furnaces switched to Slag Operations; in the late seventies, steel mills in the South also adopted this method of operation.
