西钢450m3高炉投产后,2005年4月份利用系数为1.648t/(m3.d),焦比为632kg/t,其还有很大潜力可以挖掘。 1增产潜力 (1)精料。现高炉入炉铁料综合品位为 53.22%。烧结矿品位仅为50.56%,影响铁品位的因素有:①外购精矿粉品位低、SiO2含量高,且成分波动大;应制定相应的优质优价政策,拓展精矿粉采购资源,达到与供方互惠互利;从长远来
After the 450m3 blast furnace was put into operation in West Steel, the utilization factor was 1.648t / (m3.d) in April 2005 and the coke ratio was 632kg / t, which still had great potential for excavation. A potential increase production (1) concentrate. The blast furnace into the furnace iron integrated grade of 53.22%. The sinter grade is only 50.56%. The factors that affect the grade of iron are as follows: ① The grade of purchased concentrate powder is low, the content of SiO2 is high, and the composition is volatile. Corresponding policies of high quality and favorable price should be formulated to expand the purchasing resources of concentrate powder, Mutual benefit with suppliers; in the long run
