The influence of FeO content on the cold intensity and the reduction degradation index in low temperature(RDI+3.
讨论了FeO含量对烧结矿冷强度和烧结矿低温还原粉化率RDI+3。
Study on lowering Reduction Degradation Index(RDI) of sinter;
降低烧结矿低温还原粉化率的试验研究
With increase the rate of the import iron fine ores,the sinter ore RDI decline.
烧结大量使用进口矿粉后,烧结矿低温还原粉化率指标变差,而烧结矿低温还原粉化影响高炉的透气性及焦比,通过优化配料结构,合理控制烧结矿中 SiO_2、Al_2O_3、MgO、R_2、FeO,改进不合理工艺设备,加强操作等措施,改善烧结矿低温还原粉化率指标。
Spraying CaCl_2 solution on the surface of sinter can improve the property of sinter low temperature reduction degradation,but it can also increase corrosive speed of lining plate in the washing tower for dust setting system.
针对在采用烧结矿表面喷洒CaCl2溶液进行生产时,改善了烧结矿的低温还原粉化性能,却加快了除尘系统洗涤塔内衬钢板的腐蚀速度这一现象,研究采用含硼添加剂替代部分CaCl2外喷烧结矿,能有效抑制烧结矿的低温还原粉化,很好地改善了腐蚀状况,并阐述了其对转鼓强度这一重要冶金性能的影响。
Spraying CaCl2 solution on the surface of sinter can improve the property of low temperature reduction degradation for sinter.
在采用烧结矿表面喷洒CaCl2溶液进行生产时,改善了烧结矿的低温还原粉化性能,却加快了除尘系统洗涤塔内衬钢板的腐蚀速度。
