石钢烧结厂使用50%以上的高硫矿粉作为含铁原料,像金岭镇和矿山村等高硫矿粉,其硫含量分别在1.5和2.0%以上,从前金岭矿粉配用量增高到40%左右时,烧结矿硫份即达1.0%~1.5%,对高炉冶炼优质生铁和降低焦比很不利,虽然也曾试图从烧结制度方面设法予以改善,但是,一直没能获得较大程度的好转,烧结过程的脱硫率仍然停留在80~85%的范围,因此为了使烧结矿含硫不致过高,曾使高硫矿粉限制在较低的配比范围应用。
Shigang Sintering Plant uses more than 50% of high-sulfur fines as iron-bearing raw materials, such as high-sulfur ore powder in Jinling Town and Mine Village, with sulfur contents of 1.5 and 2.0% respectively. In the past, To about 40%, the sulfur content of sinter reaches 1.0% ~ 1.5%, which is very unfavorable for smelting high-quality pig iron and reducing the coke ratio in the blast furnace. Although attempts have been made to improve the sintering system, it has not been able to obtain larger The degree of improvement, the sintering process of desulfurization rate still remain in the range of 80 ~ 85%, so in order to make the sinter sulfur will not be too high, once the high-sulfur ore powder limited to a lower proportion of applications.
