面对国内钢铁企业经营形势日益严峻,中南股份高炉迫切需要炉料结构优化尤其是配用部分低品位块矿降低生铁成本.在对低品位块矿冶金性能综合评价的基础上,采用长协主流PB块矿与低品位块矿搭配使用的方法,先小比例配加,后根据高炉顺行情况调整比例,经过高炉作业的精心调剂,确保了炉况顺行.生产实践证明,通过加强筛分、布料调整等措施,配用低品位块矿代替长协PB块矿,达到降低铁水成本的目的.
Production Practice of Using Low Grade Lump Ore in BF to Reduce Cost at ZNIS
Faced with the increasingly severe situation of domestic iron and steel enterprises,blast furnaces urgently need to reduce the cost of pig iron by optimizing the structure of the charge at ZNIS,especially by using some low-grade lump ore.On the basis of the comprehensive evaluation of the metallurgical performance of low-grade lump ore,the technical personnel of ZNIS adopted the method of the combination of Changxian main lump PB lump and low-grade lump ore in the production.The small proportion of PB lump was used first,and then the proportion of PB lump was adjusted according to the running condition of the blast furnace.After careful adjustment of the blast furnace operation,the condition of the fur-nace was ensured.The cost of hot metal was reduced by replacing Changxian PB lump ore with low grade lump ore by strengthening screening and adjusting material.
