前言 硫酸渣的有效利用有很大意义,因它含铁量一般还较高,每年全国产量又很大但过去因为它含硫量过高,影响生铁质量而未能很好利用。 经过试验证明,如果掌握好适当的配料制度和工艺制度可以得到完全适合炼鉄的燒结矿,这样就解决了石景山钢铁公司烧结厂今后合理利用硫酸渣做为烧结原料的问题。 过去认为,只有烧结细的精矿粉时,加石灰才能加快燒结速度,烧结富矿粉时没有效果 Introduction The efficient use of sulfuric acid residue is of great significance, because of its high iron content is generally high, the national annual output is very large but in the past because of its high sulfur content, the quality of pig iron and failed to make good use of. After the test proved that if we master the appropriate ingredients and process system can be fully suitable for smelting sinter, so to solve the Shijingshan Iron and Steel Company sintering plant in the future the rational use of sulfuric acid residue as a sintering raw material issues. In the past that only sintered fine concentrate powder, plus lime to speed up the sintering speed, sintered ore powder no effect
