大型高炉开炉初期渣铁分离性能的研究及应用

Study and Application of the early Separation performance of large-scale blast furnace slag and iron

本文根据高炉炼铁渣铁的物理、化学性能，分析了高炉开炉初期渣铁流动性差，甚至不分离的原因。同时依据理论研究寻找到开炉初期，尤其是前几炉铁，渣相极不合理、不均匀、物理热严重不足的情况下，使渣铁自由流动、有效分离的关键技术。并在重钢新区2500m^3高炉上得到应用，取得了第一炉铁渣铁分离的效果，促进了高炉顺利开炉。

This article introducing the physical and chemical properties of blast furnace iron slag, analysis of the early blast furnace slag iron poor mobility, and even the reasons for separation. Meanwhile, according to theoretical research to find furnace early, especially the first few furnace iron slag extremely unreasonable, uneven, physical heat seriously inadequate, so that the fi＇ee flow of iron slag, the effective separation of the key technologies. 2500m^3 in Changshou blast furnace has been applied, made the first iron furnace slag separation effect, promoting a smooth blast furnace.
