1 前言为降低生铁成本,挖掘企业内部潜力,合理利用焦炭资源,唐钢于1997年3月开始在二炼铁厂1260m~3高炉炉料中试加一定量的焦丁。经过一段时间工业试验,逐步摸索出高炉加焦丁生产的操作规律。结合本地焦丁资源情况,于1997年9月高炉开始批量加入,吨铁焦丁加入量最高达31.88kg/t。实践证明,高炉加入一定量的焦丁,既节约冶金焦又给高炉生产带来可观的经济效益,同时促进了高炉的顺行,改善了高炉料柱的透气
1 Introduction In order to reduce the cost of pig iron, tap the internal potential of enterprises and make rational use of coke resources, Tangshan Iron and Steel Co., Ltd. started trial adding a certain amount of coke in the furnace of 1260m ~ 3 blast furnace in March 1997. After a period of industrial tests, and gradually found out the operation of blast furnace plus coke production. Combined with the local Jiao Ding resources, in September 1997 the blast furnace began to join in batches, tons of iron coke added up to 31.88kg / t. Practice has proved that the blast furnace to join a certain amount of coke Ding, both metallurgical coke savings and blast furnace production to bring considerable economic benefits, while promoting the smooth blast furnace to improve the blast furnace column ventilation
