Classification treatment and resource utilization method for steel slag
The invention discloses a steel slag classification treatment and resource utilization method, and relates to the technical field of comprehensive utilization of resources. The steel slag classification treatment and resource utilization method specifically comprises the following steps: S1, conveying a slag tank containing high-temperature steel slag discharged by a rotary furnace to a wind crushing treatment line, performing wind crushing treatment on the high-temperature liquid steel slag at the upper part of the slag tank, and performing hot disintegration treatment on the residual steel slag; according to the classification treatment and resource utilization method for the steel slag, the characteristics of the high-temperature molten steel slag are combined, a subsequent full-amount efficient resource utilization system of the steel slag is considered, and classification treatment is conducted by reasonably applying a steel slag cooling and granulating treatment process according to the characteristics of mineral phases in the steel slag and the occurrence form characteristics of P; and the steel slag with high P content is subjected to granulation treatment by adopting a wind crushing treatment process, and the treated wind-crushed steel slag is reasonable in granularity and can be directly used as fine aggregate in concrete products such as roads and building materials after stabilization treatment.
本发明公开了一种钢渣分类处理及资源化利用方法，涉及资源综合利用技术领域。该钢渣分类处理及资源化利用方法，具体操作如下：S1、将盛装转电炉排出的高温钢渣的渣罐运至风碎处理线，将渣罐上部的高温液态钢渣进行风碎处理，剩余钢渣采用热闷处理。该钢渣分类处理及资源化利用方法，结合高温熔融钢渣特性，结合钢渣后续全量高效资源化利用系统考虑，根据钢渣中各矿物相的特点及P的赋存形态特点合理运用钢渣冷却粒化处理工艺进行分类处理，从而在源头实现钢渣中不同P和Fe含量的分级，对于含P高的钢渣采用风碎处理工艺进行粒化处理，处理后的风碎钢渣粒度合理，经过稳定化处理后可以直接作为细骨料用于道路、建材等混凝土制品中。
