四元碱度对高炉炉渣冶金性能影响的研究

摘要

It is well known that the metallurgical property of the BF slag is determined by the slag composition;Therefore, extensive research on the influence of (CaO+MgO)/(SiO2+Al2O3) on the blast furnace of the vis-cosity, melting temperature and desulphurizing ability, based on the furnace slag. Based on comprehensive consideration of the blast furnace’s viscosity, melting temperature and deslfurizing ability, the (CaO+MgO)/(SiO2+Al2O3) in the slag should be 1.02.%高炉炉渣的化学成分直接影响了高炉炉渣的冶金性能，根据某钢厂现场生产情况，以现场炉渣为基体，探究了(CaO+MgO)/(SiO2+Al2O3)对炉渣粘度、炉渣熔化性温度和脱硫能力的影响。研究结果表明：炉渣的(CaO+MgO)/(SiO2+Al2O3)控制在1.02左右，炉渣的粘度，熔化性温度和脱硫能力较好。
