启示一:钢铁企业发展长流程(指高炉——转炉——轧钢工艺流程),提高长流程的产钢比,是近几年的发展方向,也是降成本的最大潜力;电炉——轧钢工艺流程应以冶炼高附加值产品为主要发展方向;为此,钢铁企业应完善铁前系统配套改造,提高铁前工序的产能,对传统的小烧结机、小高炉进行扩容 Revelation A: The long process of steel enterprise development (blast furnace - converter - rolling process), increase the long process of steel production ratio is the direction of development in recent years, but also the greatest potential for cost reduction; EAF - rolling process Smelting of high value-added products should be the main direction of development; Therefore, the iron and steel enterprises should complete the transformation of the pre-iron system to improve the production capacity of the pre-iron process, the traditional small sintering machines, small blast furnace capacity expansion
