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.
