鞍钢多年来一直使用自熔性热烧结矿,强度低,粉末多,满足不了高炉冶炼的需要。近几年为了配合高炉冶炼,多次寻找改善炉料结构的途径。理论研究和冶炼试验表明,使用高碱度2.0的烧结矿和低碱度0.9的烧结矿比自熔性烧结矿强度好,粉末少,低温还原性能有所改善,焦比降低7kg 左右。高碱度烧结矿搭配低碱度烧结矿调节终渣碱度仍然是一种合理的炉料结构。 Ansteel has been using self-fluxing hot sinter over the years, low strength, powder, can not meet the needs of blast furnace smelting. In recent years in order to meet the blast furnace smelting, many times looking for ways to improve the structure of the charge. Theoretical studies and smelting tests show that sinter with high alkalinity of 2.0 and sinter with low alkalinity of 0.9 are stronger than self-fluxing sinter, less powder, and low temperature reduction performance has been improved, coke ratio decreased by about 7kg. Alkalinity sinter with low alkalinity sinter to adjust the final slag alkalinity is still a reasonable charge structure.
