摘　　要：从1995年元月开始,马钢二铁厂4座300m^3级高炉实行富氧大喷煤操作,喷吹煤种为无烟煤。在富氧率1％～2％,风温1070℃的条件下,1～5月份全厂平均煤比达130.2kg/t铁,置换比0.828,高炉操作稳定顺行。The high pulverized coal injection with oxygen-enriched blast has been carried out at four 300m3 blast furnaces of the Second Ironmaking Plant of Maanshan 1 & S Co.from January,1995-The injected coal was anthracite-Average coal injection rate for four BFs of 130-2kg/tHM and replacement ratio of 0.828 have been reached,and also a stable and smooth blast furnace operation has been achieved in period from January to May on condition that the oxygen enrichment percentage was 1 %~2%,the blast temperature was 1070℃
