苏钢自1957年筹建第一座日产百吨生铁的高炉以来,经过三十多个春秋的奋力拼搏和技术进步,已由单一的炼铁企业逐步发展成为能生产焦炭、烧结矿、生铁(27万t/年)、钢(22万t/年)、钢材(24万t/年)的中型钢铁联合企业。高炉由一座84m~3发展为84m~3×2+94m~3×2。35年来,累计生产合格生铁395.64万吨,各项技术经济指标得到改善,焦比由1000kg/t以上降到560kg/t。35年吨铁焦比共降低了500kg/t,平均每年降低14kg/t,利用系数由1.0提高到2.2,即
Since its founding of the first blast furnace of 100 tons of pig iron per day in 1957, after more than 30 years of hard work and technological progress, the company has gradually developed from a single iron-making enterprise into a coke, sinter and pig iron producer. Million t / a), steel (220,000 t / a), steel (240,000 t / a) medium-sized steel conglomerate. The blast furnace from a 84m ~ 3 to 84m ~ 3x2 + 94m ~ 3x2 35 years, a total of 3,956,400 tons of qualified pig iron production, the technical and economic indicators have been improved, coke ratio from more than 1000kg / t to 560kg / t. 35-year-iron-coke ratio decreased by 500kg / t, with an average annual decrease of 14kg / t, the utilization factor increased from 1.0 to 2.2, that is
