一般对烧结矿质量的要求是:细粒铁矿粉、精矿及高炉瓦斯灰经过烧结过程之后,应取得化学成分一致的、强度高的、气孔分布均匀的,还原性好的,块状的烧结矿。所以在烧结厂的技术条件中应包括下列必需的质量指标:(1)化学成分:包括含铁、二氧化矽(不熔解的残渣)及一氧化铁的平均指数以及报废界限。若制造特种烧结矿时,还应附有补充性的报废指标:如转炉烧结矿的含磷量,锰铁烧结矿的含锰量,熔剂烧结
In general, the requirements for sinter quality are as follows: after the sintering process, fine-grained iron ore powder, concentrate and blast furnace gas ash should be of uniform chemical composition, high strength, uniform distribution of pores, good reducibility, massive Sinter. Therefore, the technical specifications of the sintering plant should include the following necessary quality indicators: (1) Chemical composition: including the average index of iron, silicon dioxide (non-melting residue) and iron oxide and the scrap limit. If the manufacture of special sinter, should also be accompanied by supplementary scrap indicators: such as converter phosphorus content of sinter, manganese ferromanganese ore manganese content, flux sintering
