一个已知炉缸直径或炉容的高炉,只有在料柱的煤气分布均匀时才能获得最高的生产率。因而长期以来高炉工作者就致力于改善炉料和焦炭的物理化学性质,使其在下降时能承受高负荷。通过严格的分类和提高炉料的质量可减少煤气的压力损失,并又可在同样供风情况下使之含有较高的煤气量。尽管炉料和焦炭经过细致的准备,然而特别在 A blast furnace with a known hearth diameter or furnace capacity achieves the highest productivity only when the gas distribution of the feed column is uniform. As a result, blast furnace operators have long been dedicated to improving the physicochemical properties of charge and coke to withstand high loads as they fall. Through strict classification and improve the quality of charge can reduce the pressure loss of gas, and in the same case of the wind to make it contain a higher gas volume. In particular, the charge and coke are carefully prepared
