Development of advanced steel production process and steel products manufacturing technology

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.
