12 钢铁冶金分学科发展——炼钢.pdf

钢铁冶金分学科发展——炼钢 包燕平 Development of Iron and Steel Metallurgy——Steel Making Bao Yanping Since the beginning of this new century, China’s iron and steel industry has been developed constantly and rapidly. As for steel-making technology, some progress has been made in both theoretical innovation and practice of production. The upgrade of the iron and steel products has been realized and major breakthrough has been achieved in structural adjustment of products. At the same time, an important result has been accomplished in energy saving, emission reduction and environmental protection. Further development of iron and steel technology is bound to create good conditions for structural optimization and sustainable development of China’s iron and steel industry. In this paper, the development and the main technological achievements of steel-making technology in China in past two years are systematically summarized. The deficiency and gap on the current technology of steel-making subject in China are analyzed by being compared with overseas advanced technology. The main development goals and outlook of China’s steel-making technology in new century are put forward. The production technology in the process of LD steelmaking, EAF steelmaking, refining and CC are summarized and analyzed to realize the high-effectiveness and cleanness of steelmaking. The steel-making process is systematically optimized by way of resolving and integrating of metallurgical functions of steel-making process. A new recyclable steel-making process technology is formed and the level of China’s steel-making technology will be further enhanced so as to realize the production of clean steel with high efficiency, low cost and cleanness. 一、 引 言 进入新世纪以来，我国钢铁工业
