大矿批在莱钢2~#1880m^3高炉上的应用

Large Batch of Ore for Laigang 1880-m^3 B.F.#2

莱钢2^#1880m^3高炉通过煤比的提升将矿批逐渐扩大至50t／p。大矿批操作保证了高炉的长期稳定顺行，入炉焦比达到380kg／t，煤比140kg／t，利用系数达到了2．6t／（m^3·d）。

Abstract： Through enhancing the coal ratio, Laigang 1880 -m^3 blast furnace #2 gradually expanded ore weight to 50 t/p, which ensured its steady and smooth operation. With its charge coke ratio reaching 380 kg/t,coal ratio 140 kg/t and utilization factor up to 2.6 t/（m^3 · d）.
