1961年以来,鞍钢炼铁厂认真执行了党的八字方针,特别重视了提高生铁质量和降低焦比。生铁合格率1961年为97.46%,1962年达到了99.44%,1963年1～6月平均达到99.93%,尤其制钢生铁含矽含硫显著下降,今年1～6月份平均矽0.731%,硫0.035%。两年来焦比也继续降低,1961年焦比702公斤,1962年降至649公斤,今年1～11月达到了608公斤。比历史上最低焦比的1962年又降低了41公斤。有三座高炉平均在595公斤以下,三高炉10月份达到489公斤。两年来,我厂大力恢复和改进了高炉热风炉等主体设备;积极改进热风炉操作技术,提高风温;不断的研究和
Since 1961, Ansteel Ironworks has earnestly implemented the party’s eight principles, with particular emphasis on improving the quality of pig iron and reducing the coke ratio. The passing rate of pig iron was 97.46% in 1961, reaching 99.44% in 1962 and 99.93% in January-June 1963. In particular, the sulfur content in the pig iron of the steelmaking industry dropped significantly. The average silicon 0.731% from January to June this year, sulfur 0.035 %. The coke ratio has also continued to decrease over the past two years. The coke burned 702 kg in 1961 and dropped to 649 kg in 1962, reaching 608 kg from January to November this year. A further 41 kg lower than in 1962, the lowest in history. There are three blast furnaces in an average of 595 kilograms, three blast furnace reached 489 kilograms in October. Over the past two years, I plant to vigorously restore and improve the main blast furnace stoves and other equipment; actively improve the operation of hot stove technology to improve air temperature; continuous research and
