一年多以来,鞍钢在强化高炉、改进炼铁各项技术指标上取得了较大的成就(见表1)。高炉焦比从1962年649公斤/吨降到1963年606公斤/吨,1964年上半年降低到554公斤/吨。10号高炉在545公斤/吨的基础上喷以重油(55公斤/吨),焦比降到486公斤/吨;利用系数从1962年1.219吨/米~3·日上升到1963年1.312吨/米~3·日,1964年上半年上升到1.52吨/米~3·日。3、10号高炉1.7～1.8吨/米~3·日(历史先进
For more than a year, Ansteel has made great achievements in strengthening the blast furnace and improving various technical indicators of ironmaking (Table 1). The blast furnace coke ratio dropped from 649 kg / tonne in 1962 to 606 kg / tonne in 1963, and dropped to 554 kg / tonne in the first half of 1964. The blast furnace No. 10 sprayed heavy oil (55 kg / t) on a basis of 545 kg / t and the coke ratio dropped to 486 kg / t; the utilization factor increased from 1.219 t / m 3 in 1962 to 1.312 t / Rice ~ 3 · day, the first half of 1964 rose to 1.52 tons / m ~ 3 · day. 3,10 blast furnace 1.7 ~ 1.8 tons / m ~ 3 · day (history is advanced
