摘    要:简要回顾了20世纪钢铁工业生产总量、钢材质量、劳动生产率、原料及能源消耗的状况,介绍了氧气转炉炼钢、连续铸钢、炉外精炼及控冷控轧技术的特点及优势,指出了钢铁工业发展所存在的环境污染严重、能源及资源循环使用率低、钢材服役周期短等问题,描述了现代钢铁生产流程连续、高效、柔性、可控的发展特征。展望了21世纪先进钢铁生产流程中氢冶金、第2代薄板坯连铸连轧及铸 轧 材一体化等流程技术的实现。在此基础上,简要介绍了先进钢铁材料的特征及生产制造技术进展。

Abstract: The current status of iron and steel industry were summarily reviewed, i.e. gross production, quality, productivity, material and energy resources consumption. The characteristic amd advantages of oxygen converter steelmaking, continuous casting, secondary refining, controlled rolling and controlled cooling were introduced. Several problems in iron and steel industry, such as environmental pollution, low cycle availability coefficient of energy resources and service time of steels were referred. The characteristics pf up-to-date steel production process, i.e. continuous, high efficiency, flexible and controllable were described. Realization of the hydrogen metallurgy technology, secondary generation continuous thin-slab casting and rolling and integration of casting-rolling-product of the advanced steel production process in 21 century were prospected. Furthermore, the character of advanced steel products and the development of manufacturing technology were summarily recommended.
