钢铁工业是耗能大户。根据我国钢铁工业现状,国家经贸委资源司提出了钢铁工业“九五”期间节能技术政策(炼铁部分)。 1.全面实行精料方针,提高精矿品位,改进炉料结构,稳定炉料成分,提高辅料质量。强化高炉入炉料混匀设施。铁矿品位波动范围不超过±0.5%,碱度波动不超过0.05;改善燃料质量,推广应用铁水预处理技术,降低炼钢铁水S.Si含量;加强废钢分类加工,发展活性石灰生产。 2.继续推广低碳厚料层操作和混合料预
Iron and steel industry is energy-hungry. According to the current status of China’s steel industry, the State Economic and Trade Commission Resource Department proposed the steel industry “95 ” energy-saving technology policy (ironmaking part). 1. The full implementation of fine materials approach to improve the grade of concentrate, improve the charge structure, stabilize the charge composition, improve the quality of materials. Strengthen the blast furnace into the charge mixing facilities. Iron ore grade fluctuations of no more than ± 0.5%, alkalinity fluctuations of not more than 0.05; improve fuel quality, popularization and application of hot metal pretreatment technology to reduce the steelmaking molten iron S.Si content; strengthen the classification of scrap processing, the development of active lime production. 2. Continue to promote low-carbon thick layer operations and pre-mixed material
