| 摘 要： | 根据对高Al2O3(20%)炉渣性能的实验室研究结果分析,得出通过控制二元炉渣碱度1.15～1.20、四元炉渣碱度0.95～1.05,控制MgO含量10.0%～11.5%,渣温1 500～1 510℃,可以有效改善炉渣流动性,提高透气性指数和高炉稳定性。并提出了配入蛇纹石、上下部调剂、控制入炉原燃料等适合高Al2O3炉渣冶炼的措施,保证了高炉稳定顺行,提高了技术经济指标。

| Abstract: | Based on the analysis results of study on performance of high Al2O3 (20% ) slag in lab, results show that it is available to improve the flowability of slag, increase permeability index and improve stability of blast furnace ( BF) by controlling basicity of binary slag 1. 15 ~ 1. 20, basicity of quarternary slag 0. 95 ~ 1. 05, controlling MgO content in slag 10. 0% ~ 11. 5% and temperature of slag 1 500 ~ 1 510 ℃ , and the corresponding measures for smelting by high Al2O3 slag are proposed including adding serpentine, conditioning upper and lower parts and controlling charging crude fuel to ensure BF stability run and increase technical-economic indexes. |
