湘钢高Al_2O_3高炉渣脱硫能力的试验研究

Experimental Research on High Al_2O_3 BF Slag Desulphurization Ability in Xiangtan Iron and Steel Corp

根据湘潭钢铁公司的冶炼条件,以现场渣为基料,添加化学试剂,配制成高Al2O3渣系。研究在高Al2O3炉渣条件下的高炉渣主要成分、碱度等对硫分配比性能的影响。研究结果表明,在高Al2O3炉渣条件下,该高炉渣的wMgO为12%,二元碱度R为1.15最有利于脱硫。

Based on metallurgical condition of Xiangtan Iron and Steel Corp, the authors have prepared high Al2O3 dreg series by adding chemical agents into basic material made of slags found in the company. The influence of principal constituents and alkalinity of slags on sulfur distribution under the high Al2O3 slag condition is studied. It is found that, under the high Al2O3 slag condition, W（MgO） of the company is 12% and when the dual alkalinity R is 1.15, it is most advantageous to desulphurization.
