Steel slag modifier and steel slag modification treatment process
The invention discloses a steel slag modifier and a steel slag modification treatment process. The steel slag modifier comprises the following chemical components in percentage by weight: 2-50% of Al, 10-50% of SiO2, 10-30% of Al2O3, 5-25% of CaO, 0.5-3% of MgO and 0.1-5% of Fe2O3. And the particle size of the steel slag modifier is 3-10 mm. The steel slag modifier is used for modifying the high-temperature steel slag, the problems that an existing modified material and the high-temperature steel slag are not uniformly mixed and are not fully modified, and an existing steel slag modification process is large in investment, high in operation cost and the like are solved, f-CaO in the steel slag can be greatly eliminated by utilizing the process, and the whole process is economical and practical.
一种钢渣改质剂及钢渣改质处理工艺，其化学成分重量百分比为：Al：2‑50％、SiO2：10‑50％、Al2O3：10‑30％、CaO：5‑25％、MgO：0.5‑3％、Fe2O3：0.1‑5％；且，所述钢渣改质剂的粒径为3‑10mm。本发明钢渣改质剂针对高温钢渣进行改质处理，解决现有改质料与高温钢渣混合不均、改质不充分和现有钢渣改质工艺投资大、运行费用高等问题，利用本发明工艺可以大幅度消除钢渣中f‑CaO，整体工艺经济实用。
