武钢1979年先后在一座500吨顶吹氧平炉,和一座500吨重油平炉大修时,采用高铁高钙镁砂以轻柴油作结合剂打结炉底获得武钢前所未有的成果. 1.试验情况油浸高铁高钙镁砂打结料分批翻入炉内、用电夯打结。每层压实比为15～20％,用直径5mm插尺插入深度小于15mm。 WISCO successively obtained the unprecedented achievements of Wuhan Iron and Steel Company when using a 500-ton top-blown oxygen furnace and a 500-ton heavy oil hearth furnace overhaul in 1979. Using high-speed railway magnesia with light diesel oil as a binder to knot the bottom of the furnace, High-speed high-calcium magnesia to tie knot into the furnace in batches, with electric ram knot. Each compaction ratio of 15 to 20%, with a diameter of 5mm inserted into the depth of less than 15mm.
