Steel slag modifier and converter steel slag modification treatment method
The invention discloses a steel slag modifier and a converter steel slag modification treatment method, and mainly solves the technical problems of poor steel slag modification effect and high steel slag modification cost in the prior art. According to the technical scheme, the steel slag modifier comprises the following chemical components in percentage by weight: 3-11% of C, 10-50% of SiO2, 10-30% of Al2O3, 5-25% of CaO, 0.5-3.0% of MgO and 1-3% of Fe2O3, and the sum of the weight percentages of all the components is 100%. The raw materials of the steel slag modifier are industrial wastes and are wide in source, the preparation process is simple, and the production cost is low; the steel slag modifier is uniformly mixed with high-temperature steel slag, the mass content of F.CaO in the modified steel slag is less than or equal to 2.0%, the mass content of F.MgO in the modified steel slag is less than or equal to 0.1%, and the modified steel slag is stable in performance.
本发明公开了一种钢渣改性剂及转炉钢渣改性处理的方法，主要解决现有钢渣改性效果差、钢渣改性成本高的技术问题。技术方案为，一种钢渣改性剂，其化学成分的重量百分比为：C：3～11％，SiO2：10～50％，Al2O3：10～30％，CaO：5～25％，MgO：0.5～3.0％，Fe2O3：1～3％，各成分的重量百分比之和为100％。本发明钢渣改性剂原料为工业废弃物，来源广、制备工艺简单、生产成本低；钢渣改性剂与高温钢渣混合均匀，改性后钢渣中F.CaO的质量含量≤2.0％，F.MgO≤0.1％，改性后的钢渣性能稳定。
