以攀钢高炉现行生产渣为基准,配制TiO_2-CaO-SiO_2-Al_2O_3-MgO五元渣系,比较系统地研究了钛渣还原变粘过程。结果表明,还原过程中钛渣熔化性温度的变化不是粘度增大的直接原因。实验发现,与粘度显著增大相对应的是渣中有一定数量的TiC,同时还有相当数量的TiO。TiC并非是钛渣变粘的唯一因素。试验结果充分证明:碱度CaO/SiO_2对钛渣还原变粘特性影响很大,在组成因素中起主导作用。
Based on the current production slag in the blast furnace of Panzhihua Iron and Steel (Group) Co., Ltd., a TiO 2 -CaO-SiO 2 -Al 2 O 3 -MgO ternary slag system was prepared. The reduction and visbreaking process of titanium slag was systematically studied. The results show that the change of melting temperature of titanium slag is not the direct reason for the increase of viscosity. The experiment found that there was a certain amount of TiC in the slag and a considerable amount of TiO, corresponding to the significant increase in viscosity. TiC titanium slag is not the only variable sticky. The test results fully prove: Alkalinity CaO / SiO 2 has a great influence on the reduction sticking characteristics of titanium slag, and plays a leading role in the composition factors.
