摘要

铁水预处理KR法脱硫产生的脱硫渣具有污染大

毒化性明显

渣处理工艺单一

可选择的处理工艺有局限性的特点

资源化利用难度较大。第二炼钢厂开发了加快脱硫渣冷却速度

促使渣罐内铁液急剧降温

CO快速析出和燃烧的KR脱硫渣去毒化工艺和用转炉液态渣-KR脱硫渣的改质热闷渣工艺

明显改善了工作环境

有效转化回收转炉渣中的氧化铁和实现KR脱硫渣的资源化利用。

Abstract

The characteristics of desulphurized sludge produced from hot metal pretreatment KR desulphurizing process are high pollution

obvious poisoning

unitary slag treatment process

limitations of selectable treatment process

and difficult recycling of resources. The de-poisoning process of KR desulphurized sludge by quick cooling desulphurized sludge

promoting hot metal in cinder pot quick dropping in temperature and CO fast escaping and burning

and the modified sealed hot slag process of KR desulphurized sludge by using converter liquid slag are developed at No2 steelmaking plant

It is obvious to improve working environment

available to translate and retrieve the iron oxide in converter slag and realize the KR desulphurized sludge recycling and utilizing of resources.
