1　前言助熔性烧结矿是中钢公司高炉的主要铁料。在烧结机中 ,加入诸如石灰石、蛇纹石和硅砂等熔剂 ,以改进铁矿石的烧结特性 ,提供炉渣所需成分。理论上讲 ,如果能够达到这些目的 ,在烧结矿中减少熔剂耗量 ,不仅能降低成本 ,也能减少高炉的渣量 ,有利于降焦和喷煤操作。当然 , 1 Introduction Fusible sinter is the main iron of Sinosteel blast furnace. In sintering machines, fluxes such as limestone, serpentine and silica sand are added to improve the sintering characteristics of the iron ore and provide the desired composition of the slag. Theoretically, if these goals can be achieved, reducing flux consumption in sinter will not only reduce costs, but also reduce the amount of slag in the blast furnace, which is good for the operation of coal tar-lowering and coal injection. of course ,
