中文摘要：

传统钢铁工业具有规模巨大、能源与资源密集、工艺路线曲折的特点.中国能源和资源的状况要求未来钢铁工业引入循环经济的理念,用创新的思维开发新流程,逐步向冶金材料制备、能源转换和社会废弃物处理三大功能方向转变.结合这一战略思路,近年来,上海大学现代冶金与材料制备重点实验室开始在铁矿微粉低温氢还原、碳-氢铁浴混合终还原、废钢中痕量元素脱除、时空多尺度冶金理论与建模等方面进行一些相关的基础研究和探索.

英文摘要：

The traditional iron and steel industry are characterized by its huge scale,heavy consumption of energy and resources,and complicated technical processes.Due to the limited energy and resource deposit,the concept of circulation economy needs to be introduced in the next generation iron and steel industry.New processes must be developed through technical innovation,and converted progressively to three main functions： metallic material preparation,energy conversion,and social wastes treatment.With this strategy,fundamental studies have been carried out at the Key Laboratory of Modern Metallurgy Materials Processing,Shanghai University.The researches involve hydrogen reduction of fine iron ore at low temperature,mixture end-reduction in iron bath with carbon and hydrogen,trace elements separation from scrap,metallurgical theory,and modeling with multi-scales of time and scope,etc.
