石钢烧结厂从九月份开始进行了金岭高硫矿配比的试验,成功的解决了金岭矿粉的脱硫和合理使用的问题。金岭矿粉含硫平均在1.4%以上,烧结料中随着金岭矿配入量的提高,烧结矿含硫相应增高,当配比达到矿粉的40%时,烧结矿含硫达0.10～0.15%,同时烧结矿强度也随之变坏,仅从调整烧结操作制度着手一直难于改善,为了解决这个难题,八月份进行了系统的试验室试验,终于获得了金岭高硫矿和一部分精选粉配比的合适方案,显著的提高了脱硫效率,同时,保证了良好的烧结矿强度。
Shijiazhuang sintering plant started from September Jinling high-sulfur ore ratio test, the successful solution to the Jinling slag desulfurization and the rational use of the problem. The average sulfur content of Jinling ore powder is above 1.4%. With the increase of the amount of Jinling ore in the sintering material, the sulfur content of the sinter increases accordingly. When the proportion reaches 40% of the ore powder, the sulfur content of the sinter reaches 0.10 ~ 0.15%. At the same time, the strength of sinter also deteriorates. It is difficult to improve only by adjusting the sintering operation system. In order to solve this problem, a systematic laboratory test was conducted in August and finally gained some valuable information The selection of appropriate powder proportion of the program, significantly improve the desulfurization efficiency, at the same time, to ensure a good sinter strength.
