摘  要:含钛高炉渣是高炉冶炼过程中的副产物,研究含钛高炉渣熔化特性对优化高炉冶炼过程和提高炉渣处理效率提供了理论依据。以四川省德胜钢铁有限公司含钛高炉渣为研究对象,采用Fact Sage^(®)热力学软件模拟研究不同含量的Al_(2)O_(3)对含钛高炉渣的熔化特性的影响。研究发现,Al_(2)O_(3)对含钛高炉渣开始熔化温度、完全熔化温度均有影响,其中对含钛高炉渣开始熔化温度影响效果不显著,开始熔化温度约为1164℃;对含钛高炉渣开始熔化温度影响效果较为显著,完全熔化温度约为1439℃,Al_(2)O_(3)含量每增加0.5%,含钛高炉渣完全熔化温度降低约3℃。研究结果为高炉冶炼过程中炉渣的管理提供了重要的理论依据。Titanium high slag is a byproduct in the blast furnace smelting process,and studying the melting characteristics of titanium high slag provides a theoretical basis for optimizing the blast furnace smelting process and improving the efficiency of blast furnace slag treatment process.Then the effect of Al_(2)O_(3) with different content was investigated.It is found that Al_(2)O_(3) has an effect on the initial melting temperature and complete melting temperature of high titanium slag,and the effect on the initial melting temperature is about 1164℃;on the initial melting temperature of high titanium slag,the complete melting temperature is about 1439℃.For each 0.5%increase of Al_(2)O_(3) content,the complete melting temperature of high titanium slag decreases by about 3℃.The results provide an important theoretical basis for the management of slag during blast furnace smelting.
