Metallurgical engineering through the study

As an important tool subject, metallurgical engineering is characterized by extracting metals or compounds from ores and other resources and making products with good performance and economic value. At the same time, metallurgical engineering is the foundation of national economic construction, is a sign of national strength and industrial development level, it for machinery, energy, chemical industry, transportation, construction, aerospace industry, national defense and other industries to provide the required material products. The development of modern industry, agriculture, national defense and science and technology constantly put forward new requirements for the metallurgical industry and promote the development of metallurgical science and engineering technology, in turn, the development of metallurgical engineering continues to provide a new material basis for the progress of human civilization.

According to the division of the Ministry of Education, the discipline of metallurgical engineering is divided into three secondary disciplines, namely metallurgical physical chemistry, iron and steel metallurgy and non-ferrous metal metallurgy. For relevant professionals, metallurgical physical chemistry is the theoretical basis for the application of metallurgical engineering, and iron and steel metallurgy and non-ferrous metal metallurgy are specific application directions. However, metallurgical engineering is a typical interdisciplinary science, and for modern metallurgical engineering, it is not enough for researchers and students to master basic knowledge such as metallurgical physical chemistry. In recent years, the field of metallurgical engineering and materials engineering, environmental engineering, mining engineering, control engineering, computer technology and other engineering fields as well as physics, chemistry, engineering thermal physics and other basic disciplines are closely related, mutual promotion, common development. Solve the key scientific problems in the whole process from basic research in the laboratory to industrial application, provide advanced industrialization technology and various functional products to meet the development of high-tech industry and improve the quality of people's life, and maximize energy conservation and emission reduction.

The development of China's metallurgical engineering discipline not only aims at the international frontier of the discipline at all times, but also keeps innovating and forging ahead closely around the medium and long-term planning and major needs of national scientific development. With the adjustment of the structure of traditional metallurgical industry and the rapid development of high and new technology in materials, nano, information, machinery and other disciplines, the basic research of metallurgical engineering in China has made great progress and development. At the same time, the research team in the field of metallurgical engineering is also growing, the research level is rapidly improving, the research ideas are constantly expanding and innovating, and the cases of successful industrialization are also increasing. With the continuous development of metallurgical engineering and the cross-integration with related disciplines, The new metallurgical physical chemistry disciplines include metallurgical thermodynamics and thermochemistry, metallurgical kinetics and process strengthening, metallurgical melts, basic theory of metallurgical electrochemistry and electrochemical engineering, secondary resource chemistry of non-ferrous metals, physical chemistry of materials and new energy materials, physical chemistry of nanomaterials, physical chemistry of resources and environment, physical chemistry of green metallurgy and physical chemistry of materials preparation, and metallurgical non-lines Sex theory, metallurgical physical chemistry of external field action, biological metallurgical physical chemistry, new methods of metallurgical physical chemistry research, new testing technology and new instruments, etc. This is the demand for the self-improvement and reform of the metallurgical engineering system, and also the demand for the development of the national basic industrial science and technology industry.

At the same time, as the pillar industry of China's national economic construction, the metallurgical industry is also an important source of environmental pollution. In order to promote the green and healthy development of the metallurgical industry and the progress of environmental protection, how to maximize the realization of "energy saving, consumption reduction and emission reduction" has become one of the main goals of the metallurgical industry. In the process technology, it is necessary to focus on the research and development of energy saving, environmental protection and clean production technology system solutions for the iron and steel industry, and focus on some weak links to strengthen research and development. It is necessary to study the comprehensive treatment of sintering flue gas, the rational utilization technology of coke oven gas, the systematic treatment of coking water, and the low-carbon smelting and short process technology that reduces CO₂ emissions, and strengthen the evaluation and comprehensive management of the whole life cycle of the product in the extension and management of the industrial chain, and organically combine the design, procurement, transportation, production, marketing and product recycling. To minimize the impact on the environment in line with the green development direction. The discipline of metallurgical engineering, as the pillar industry of the country and an important basic discipline, its important strategic position determines the key role to play in the realization of the above-mentioned planning objectives. The rapid development of Chinese economy and society also provides a broad space for the development of the discipline of metallurgical engineering in our country.

After decades of efforts, metallurgical engineering discipline in our country has initially formed a relatively complete scientific and technological innovation system from basic research to industrial application. China has approved the establishment of more than 10 first-level doctoral programs in metallurgical engineering, formed a large-scale metallurgical engineering higher education system, approved the establishment of 5 state key laboratories, covering new technology of iron and steel metallurgy, powder metallurgy, refractory materials, special steel metallurgy and preparation, advanced steel process and other fields.

In order to dedicate the achievements of metallurgical engineering from basic research to industrial application in the past 20 years to the researchers and teaching staff in the field of metallurgy in China, especially the young scholars engaged in basic research, and help them better condenze the core scientific problems of chemical engineering in recent years, Learn how China's outstanding metallurgical workers, starting from the domestic and foreign status quo of the research field to be launched in this discipline, find out the main scientific problems and technical bottlenecks, propose solutions, and how to make innovative discoveries and breakthrough progress through in-depth research and move towards the scientific inquiry method of industrial application. The Engineering Science Division 1 of the Engineering and Materials Science Department of the National Natural Science Foundation of China invites outstanding experts and discipline leaders active in the field of metallurgy in China, from basic research to industrial applications, to write their research ideas and results.

Through strict screening, 22 typical achievements in 3 fields were selected and compiled into this work, which reflects the latest progress in the frontier and cross fields of metallurgical engineering in China - Through Research in Metallurgical Engineering - from basic research to industrial application.

There are four chapters in this book, the first chapter is the introduction, focusing on the evolution of metallurgical engineering discipline, the important position in the national economy, the research status and development trend at home and abroad, and the development trend of iron and steel metallurgy and non-ferrous metallurgy industry in China. Chapter 2 to 4 introduces iron and steel metallurgy, non-ferrous metallurgy and resource utilization.
