张钢有五座高炉(120m~3×3+100m~3×2),配有24m~2烧结机两台,1996年开始生产土烧球团。截止1998年5月各高炉生产时间分别如下:1号炉7年6个月,2号炉8年9个月,3号炉10年5个月,4号炉11年10个月,5号炉4年9个月。除5号炉生产时间稍短以外,其余各高炉均到了炉役后期。随着市场经济的进一步深化,张钢面临的形势越来越严竣,如何充分利用科学技术,实行内部挖潜,实现高产、优质、低耗,降低生铁成本,提高市场占有率,是张钢面临的重大课题。1997年通过采取各种措施,取得了良好的经济效益。 1 改变炉料结构在进一步理解“精料”方针的基础上,针对我厂的炉料结构进行剖析,我厂以前使用的炉料结构为高碱度烧结矿+酸性球团矿
Zhanggang has five blast furnaces (120m ~ 3x3 + 100m ~ 3x2) equipped with two sintering machines of 24m ~ 2. In 1996, it started producing indigenous burning pellets. As of May 1998 blast furnace production time as follows: 1 furnace 7 years and 6 months, 2 furnace 9 years 8 years, 3 furnace 10 years and 5 months, 4 furnace 11 years and 10 months, 5 Furnace 4 years and 9 months. Except for the shorter production time of No. 5 furnace, the rest of the blast furnaces reached the later stage of the furnace service. With the further deepening of the market economy, Zhang Gang is facing a more and more serious situation. How to make full use of science and technology, implement internal tapping to achieve high output, high quality, low consumption, reduce pig iron costs and increase market share A major issue. In 1997, through various measures, it has achieved good economic benefits. 1 change the charge structure In further understanding of “concentrate ” principle, based on the analysis of the charge structure of our plant, the structure of the charge I used before the plant is high alkalinity sinter + acid pellets
