三明钢铁厂三座高炉(944m~3)上半年产铁372572t,同比多产铁64437t,增长21.91%,利用系数2.190t/(m~3.d),同比提高0.359t/(m~3.d),入炉焦比497kg,同比降低58kg,节焦21609t,节焦价值1309.53万元,上半年生铁成本1099.21元/t。为了提高铁前生产水平,为转炉多提供铁水,总厂上半年召开8次铁前生产协调会。主要采取以下措施: 1.增产烧结矿,提高熟料比,提高烧结矿品位上半年生产烧结矿664563t,同比多产55522t,增长9.12%。高炉熟料比达到92.77%。同比提高5.73%,5月份95.71%,6月份96.07%。上半年烧结矿平均品位达到54.59%,同比提高1.79%,5月份品位55.84%,6月份55.77%。上半年1、3号高炉
The three blast furnaces at Shaming Iron and Steel (944m ~ 3) produced 372572t of iron in the first half of the year, with a year-on-year increase of 64,437t and an increase of 21.91%. Utilization coefficient was 2.190t / (m ~ 3.d), an increase of 0.359t / (m ~ 3) d), into the furnace coke ratio 497kg, down 58kg, section coke 21609t, section coke value of 1309.53 million yuan, the first half of pig iron costs 1099.21 yuan / t. In order to improve the level of pre-iron production and provide more hot metal for the converter, the Plant held 8 pre-production coordination meetings in the first half of the year. Mainly take the following measures: 1. Increase sinter production, improve clinker ratio, improve sinter grade production sinter 664563t in the first half, 55522t more than the same period, an increase of 9.12%. Blast furnace clinker ratio reached 92.77%. Up by 5.33% from the same period of last year, from 95.71% in May to 96.07% in June. In the first half of the year, the average grade of sinter reached 54.59%, an increase of 1.79% as compared with the same period of last year; the grade of 55.44% in May and 55.77% in June. In the first half 1,3 blast furnace
