变碱度含镁球团矿工业试验 总被引:1,自引:0,他引:1
2004年包钢扩大产能,分别进行265m。烧结机、5^#高炉(1260m^3)的建设和2^#高炉(由1513m^3改为1780m^3)的扩建改造。7月中旬2。高炉改造完工投入生产。2^#高炉投产后,炼铁厂4座高炉投入生产,日产水平在16000t~16500t之间。由于265m^2烧结机尚未投产,烧结矿生产能力明显不足, 相似文献

2013年260m2烧结机使用杂矿烧结以来,平均转鼓指数为74.44%,不能满足高炉对烧结矿强度的要求,为实现保质保量供高炉的生产目标,烧结厂采取严格控制原料和燃料粒度、加强混合料水份控制、提高料层操作等措施之后,烧结矿强度得到改善。进入2014年后,烧结矿转鼓指数月均都达到75.5%以上,满足了高炉对烧结矿转鼓指数的要求,为高炉顺行作出了一定的贡献。 相似文献

AbstractFrom a sinter production point of view, it is important to optimise the sintering process with regard to both sinter quality and production rate. In sintering, airflow rate within the sinter bed decides the production rate and its physical and metallurgical properties. To study the influence of airflow rate (flame front speed) on sinter production and sinter quality, pot grate sintering experiments were conducted at sinter grate suction pressures ranging from 900 to 1700 mm water column over the sinter bed. During sintering, time–temperature data were recorded, and mineralogical studies were carried out. This study reveals that increase in sinter grate suction pressure through the sinter bed from 900 to 1700 mm water column significantly improved the sinter productivity from 34·37 to 48·90 t/m2/day; however, the physical and metallurgical properties of the sinter at higher suction pressure were not optimum with respect to blast furnace requirements. The maximum sinter productivity with desired physical and metallurgical properties was obtained at suction pressure 1300 mm water column. At this pressure, improvement in sinter quality was due to optimum firing temperature and enough retention time available for formation of mineral phases. At an airflow rate 1300 mm water column, sinter productivity was 41·0 t/m2/day, sinter strength (TI) was 73·10%, reduction degradation index was 25·0 and reducibility was 71·50%. 相似文献
