为探索二元碱度、MgO和Al2O3含量对鲅鱼圈高炉炉渣性能的影响,进行了配渣试验研究及炉渣成分预测模型开发工作。结果表明,在采用高比例进口矿条件下,其合理的造渣制度为碱度小于1.17,渣中wMgO在9%左右,wAl2O3小于16%,wAl2O3/wSiO2小于0.45。通过炉渣成分预算可测算炉料结构发生改变,尤其是进口块矿比例和Al2O3含量波动大的矿种变化时预算炉渣成分。
In order to explore the influence of binary basicity, MgO and Al2O3 contents on the performance of the Bayuquan blast furnace slag, the slag allocation experiment and slag composition prediction model development were carried out. The results show that the rationality of slagging is that alkalinity is less than 1.17, slag wMgO is about 9%, wAl2O3 is less than 16% and wAl2O3 / wSiO2 is less than 0.45 under the condition of high proportion of imported ore. Through the slag composition budget can be measured structure of the charge changes, especially the proportion of imported lump ore and Al2O3 content fluctuations in the budget changes in the composition of the slag.
