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。
In 2013 260m2 sintering machine using miscellaneous ore sintering, the average drum index of 74.44%, can not meet the requirements of the blast furnace for sintering strength, in order to achieve quality and quantity for blast furnace production goals, sintering plant to take strict control of raw materials and fuel particle size, After strengthening the moisture control of the mixture and improving the operation of the material layer, the strength of the sinter is improved. After entering 2014, the monthly average of the sinter drum index reached more than 75.5%, meeting the requirements of the blast furnace for the sinter drum index and making a certain contribution to the blast furnace forward.
