摘要
对首钢迁钢1号高炉实现300kg/t以下焦比的冶炼实践进行了总结。首钢迁钢1号高炉通过完善高炉操作制度,改善焦炭质量,提高富氧率和风温,达到了焦比288.35kg/t、煤比162.4kg/t的生产指标,有效降低了炼铁成本。
The essay summarizes the practice on pulverized coal injection and reducing coke consumption in No. 1 blast furnace of Shougang Qian＇an Iron ＆ Steel Co. Ltd. By the means of optimizing operation system of blast furnace, beneficiating coke quality, increasing oxygen enrichment ratio and blast air temperature, No. 1 blast furnace of Shougang Qian＇ an Iron ＆ Steel Co. Ltd. realized the production target of 288.35kg/t coke ratio and 162.4 kg/t coal ratio and energy consumption of ironmaking is effectively reduced.
