近年来,马鞍山钢铁公司在9座300 m~3级高炉上,全面贯彻精料方针,改进高炉操作制度,积极采用先进适用技术,逐步提高装备水平,在建立与推行操作标准化条例等方面做了大量的工作,经过10年的努力,炼铁生产技术取得了较大的进步。1988年与1977年相比,高炉利用系数由1.524 t/(m~3·d)提高到2.213 t/(m~3·d),焦比由655 kg/t降至479 kg/t,9座高炉从1985年起,每年都达到全国特等高炉标准。
In recent years, on 9 300m ~ 3 blast furnaces, Maanshan Iron & Steel Co., Ltd. has fully implemented the principle of fine materials, improved blast furnace operation system, actively adopted advanced and applicable technologies, and gradually raised the level of equipment. In the course of establishing and promoting operation standardization regulations, A lot of work, after 10 years of hard work, made iron-smelting production technology has made great progress. Compared with 1977, BF utilization increased from 1.524 t / (m ~ 3 · d) to 2.213 t / (m ~ 3 · d) in 1988, and the coke ration decreased from 655 kg / t to 479 kg / t. Block blast furnace since 1985, every year to reach the country’s special blast furnace standards.
