Abstract
This paper expounds the important role and status of steel materials in the economic and social development, analyzes the development history and current situation of China’s iron and steel industry, and discusses the important role in promoting the development of science and technology progress for steel industry, and points out the future development orientation of China’s steel industry. Also this paper reviews the development course of Chinese metallurgical engineering design evolution, analyzes the relationship between engineering methodology and metallurgical engineering design method, metallurgical engineering design status and the function, and elaborates the physical essence of steel manufacturing process and modern steel manufacturing process of the "three functions" . From the physical essence of steel manufacturing process, characteristics and dynamic operating characteristics factors, path design method, dynamic and orderly operation of dynamic coupling process,etc., the identification and definition of metallurgical engineering design problem are proposed. The methodological system of concept design, top-level design, dynamic precision design for modern iron and steel metallurgy engineering method, as well as the systematic integration of modern steel manufacturing process and structure optimization, economic and social assessment are proposed.
