摘要
攀钢4号高炉从1994年5月开始采用中心加焦技术，在一定程度上改革了高炉顺行，改善了中心料柱的透气性，发展了中心气流，悬料次数明显减少，焦比明显降低，对改善各项技术经济指标取得了一定效果．
The central core charging technology has been applied to No. 4 BF at Pan Gang since May, 1994,which to a celtain degree achieved a more smooth operation of BF, improved the gas permeability of central stock column, developed central gas flow, leduced the times of fueling obviously, decreased coke ratio,achieved a certain effect on improvement of various technological economical targets.
