近年来,为了满足提高高炉利用系数等的需要,高炉炉缸铁水温度有所提高,这就导致了炉缸耐火材料内衬的极度磨损。虽然目前有很多关于炉缸耐火材料及其性能对比试验的报道,但几乎没有关于这些材料的反应机理和进一步变质方面的报道。对比了两种不同碳含量材料实验室实验结果,弄清了炉缸内衬耐火材料的各种反应机理和改善其恶化的措施。根据炉缸内衬的磨损机理,提出一些实际操作措施,以延长高炉寿命。
In recent years, in order to meet the need to improve the utilization factor of the blast furnace, the temperature of the molten iron in the blast furnace hearth has been raised, which leads to the extreme wear of the refractory lining of the hearth. Although there are a lot of reports on the comparative tests of furnace refractory materials and their properties, there are few reports on the reaction mechanism and further deterioration of these materials. The experimental results of two different carbon content materials were compared, and various reaction mechanisms of the refractory in the hearth and the measures to improve the deterioration were clarified. According to the wear mechanism of hearth liner, some practical measures are put forward to prolong the life of the blast furnace.
