MgO含量对高碱度烧结矿的影响研究
|
摘要
以萍钢原料为研究对象,使用烧结杯研究了不同MgO含量对高碱度烧结矿质量的影响。结果表明:随着MgO含量的增加,烧结矿各项指标都受到不同程度的影响,垂直烧结速度降低,成品率降低,转鼓指数略有升高,低温还原粉化指数升高,T_(10%)呈下降的趋势,T_(40%)呈上升的趋势,ΔT呈上升的趋势。综合考虑这些参数,确定了高碱度烧结矿适宜MgO含量为2.8%左右。
The effect of MgO content for the quality of high basicity sinter was studied by sinter pot tests using raw materials from Pingxiang steel Co., Ltd. The results show that, with the increase of MgO content, all the indexes are changed more or less. The yield and vertical sinter speed decrease, and the drum index increases gradually, and the low-temperature reduction powdering index increases. As for the load soft melt performance, the T10%rise, while the T40%go down, and the ΔT show a rising tendency. Considering these parameters, the suitable MgO content of high basicity sinter is about 2.8%.
