根据邯钢目前高炉的冶炼条件，以现场渣为基准，研究了炉渣碱度、MgO、Al2O3和TiO2含量对炉渣熔化性能的影响。结果表明，随碱度增加，炉渣粘度和熔化性温度先下降后提高。较高的MgO含量可降低炉渣粘度和熔化性温度，提高炉渣流动性。随渣中Al2O3含量增加，炉渣流动性变差。渣中TiO2含量对炉渣粘度和熔化性温度影响不明显。本试验条件下，合理的炉渣组成为：二元碱度为110~115，MgO含量为1119%左右，Al2O3含量为1439%左右，TiO2含量可根据现场原料变化情况而定。
According to the metallurgical condition of Hangang, the effects of R2, MgO, Al2O3, TiO2 content on slag melting properties were studied based on the slag found in the company. The results show that when R2 increases in BF slag the viscosity and melting temperature firstly decrease, and then increase. Higher MgO content can reduce slag viscosity and melting temperature which increases the fluidity. Slag fluidity becomes worse with the increase of Al2O3 content. The effect of TiO2 content on slag viscosity and melting temperate is not distinct. According to the experimental condition, the reasonable slag composition of Hangang slag is: R2 is controlled in the range of 11 to 115, MgO content about 1119%, Al2O3 content about 1439%, and TiO2 content changes with the Hangang material condition.
