High-temperature steel slag modification treatment method, modified steel slag and application of modified steel slag
The invention provides a high-temperature steel slag modification treatment method, and belongs to the technical field of comprehensive utilization of industrial solid waste. The method comprises the following steps: mixing liquid steel slag, a simple substance carbon substance recovered substance and a steel slag online modifier to obtain a mixture; and performing constant-temperature treatment on the mixture to obtain modified steel slag, wherein the mass fraction of the simple substance carbon substance recovered substance in the mixture is 2.0%-5.0%; and the mass fraction of the steel slag online modifier in the mixture is 7.0%-40.0%. The method can effectively improve the recovery ratio of Fe in the steel slag, and is simple and efficient in process and low in investment cost. The invention further provides the modified steel slag and application thereof.
本发明提供了一种高温钢渣改性处理方法，属于工业固体废弃物综合利用技术领域，所述方法包括：将液态钢渣、单质碳物质回收物和钢渣在线改性剂混合，获得混合料；将所述混合料进行恒温处理，获得改性钢渣；其中，所述混合料中所述单质碳物质回收物的质量分数为2.0％‑5.0％；所述混合料中所述钢渣在线改性剂的质量分数为7.0％‑40.0％。该方法能够有效提高钢渣中Fe回收比例，且工艺简单高效，投入成本低。本发明还提供了一种改性钢渣及其应用。
