介绍了钢渣池式热闷新工艺应用于新余钢铁集团钢渣处理工程的情况,并将其与原有钢渣处理工艺在处理效果上相对比,发现应用钢渣热闷处理工艺,最大限度地消除钢渣的不稳定因素并实现金属铁与其他连生体的充分解离和尾渣充分利用是钢渣资源化处理利用的最佳途径,采用钢渣热闷处理工艺后钢渣产品中渣钢品位在85%以上,磁选粉铁品位达到40%以上,尾渣铁品位降至1.6%,钢渣中f-CaO含量小于3%,且钢渣粉化效果较好,满足用于生产钢渣微粉的原料要求,为钢渣的资源化利用提供了良好的前提条件。
This paper introduces the new technology of steel slag pool hot stuffy used in the steel slag treatment project of Xinyu Iron and Steel Group, and compared with the original steel slag treatment process in the treatment effect, found that the application of steel slag hot boring treatment process to minimize the slag Unstable factors and to achieve full dissociation of metal iron and other organisms and the full utilization of tailings is the best way to deal with the use of steel slag resources, the use of slag heat nauseating process steel slag slag grade more than 85%, magnetic The grade of iron powder is more than 40%, the grade of tailings iron is reduced to 1.6%, the content of f-CaO in slag is less than 3%, and the effect of slag powdering is better, which meets the raw material requirements for the production of slag powder, Utilization provides a good prerequisite.
