铁矿石、烧结矿和球团矿冶金性能的好坏直接影响高炉生产的指标。过去人们把注意力放在原料的化学组成及其冷态下的物理性能方面(如粒度、耐磨性和机械强度等)无疑是重要的,但是只凭借这些指标还不能充分说明原料是否能满足高炉冶炼的要求。近年来国内外普遍认识到铁矿石高温状态下冶金性能也是评价炉料质量的重要指标。 Iron ore, sinter and pellet metallurgical properties of a direct impact on blast furnace production indicators. In the past, it was undoubtedly important that attention should be paid to the chemical composition of the raw materials and the physical properties under cold conditions (such as grain size, abrasion resistance and mechanical strength), but these indexes alone can not fully explain whether the raw materials can satisfy Blast furnace smelting requirements. In recent years, it is generally recognized at home and abroad that the metallurgical properties of iron ore at high temperature are also important indexes for evaluating the quality of charge.
