钢铁工业的循环经济与自主创新

CIRCULAR ECONOMY AND INDEPENDENT INNOVATION OF IRON & STEEL INDUSTRY IN CHINA

综述了中国钢铁工业的现状,指出我国重点大、中型钢铁企业的生产工艺技术已经达到了一个“临界”的状态,继续努力即可形成自主创新的钢铁冶金工艺。阐述了在过去的五十年里,钢铁工业从工艺技术走向工程科学的进程,这包括了从平衡态的钢液还原和精炼到不平衡态的凝固和轧制方面的发展。钢铁工业在二十一世纪要生存、发展,就需成为循环经济的示范产业。在循环经济思想指导下开发新工艺、新技术、新型钢铁产品以及新型的冶金装备的设计能力和集成制造能力,把中国由一个钢铁大国建成钢铁强国。

rhe present situation of iron and steel industry in China is reviewed. It is pointed out that the manufacturing and processing technology in the key enterprises have reached a ＂critical＂ state, from which independently innovated metallurgical process of iron and steel can be obtained if efforts are continuously contributed. It is described that in the recent 50 years, iron and steel industry changed from processing technology to engineering science, including the searching for equilibrium reduction of liquid steel and steel refining as well as the searching for the un-equilibrium solidification and roiling. The iron and steel industry must be the model of circular economy so as to co - exist with other industries and develop further. Under the guidance of the principle of circular economy, new technology, new processing and new type of steel product must be developed and the ability of designing up to date metallurgy equipments and combined manufacturing must be raised. Through the way stated above, China can be developed from a country of steel with great quantity to a country of steel with great quality.
