Refractories belong to the category of inorganic non-metallic materials and are the key basic materials for high-temperature industries such as iron and steel. At the same time, as a highly applicable subject, refractories themselves are developed with the development of high-temperature industrial production equipment and technology such as iron and steel. Developmental. During the last 10 years of the 20th century, the steel, building materials, light industry and other industries, especially the iron and steel industry, quickly reached a major stage through the introduction of advanced technology and equipment. "Many varieties do not have them, and a small number of existing varieties have a significant quality gap compared with foreign ones. Therefore, we must rely on state support and organize the entire industry to tackle scientific and technological problems in accordance with the development needs of high-temperature industries such as steel. Through the digestion and absorption of imported products and technologies, and based on China’s abundant refractory resources such as high bauxite, magnesite, dolomite, quartz, graphite, etc., developed a series of high-quality refractory raw materials and high-quality products with Chinese characteristics. With independent process technology and forming production capacity, replacing imports and realizing localization, China is a country with large refractory resources, but the quality of raw materials is backward, the quality of refractory materials, production technology, and equipment are backward. Keep up with the continuous development of high-temperature industries such as iron and steel. Pace and meet demand.

With the support of the leaders of the Ministry of Metallurgy (Bureau) and the State Planning Commission and the State Economic and Trade Commission, driven by the rapid development of the iron and steel industry, and with the efforts and organization of the author of this article, we hold high the banner of "Mr. Zhong Xiangchong", Seizing the historical opportunities of the last two five-year plans of the 20th century, the refractory industry has won six major national scientific and technological projects (including industrial test projects, scientific and technological research projects, engineering research centers, and “one "Long" project, etc.) and the most financial support (financial appropriation + special discount loan for technological transformation). These items are:

(1) The national "Eighth Five-Year Plan" key industrial test project of the State Planning Commission-Qinghai brine magnesia industrial test project. 

(2) National "Eighth Five-Year" key scientific and technological research plan of the State Planning Commission-"Research on the production technology of high-quality refractory materials". 

(3) The "One-stop" sub-project of the "Eighth Five-Year Plan" of the National Economic and Trade Commission "Special refractory materials for external refining technology". 

(4) "National Engineering Research Center for Refractories" project of the State Planning Commission. 

(5) The State Planning Commission's National "Ninth Five-Year" Key Scientific and Technological Tackling Plan-"Development of Special Refractory Products". 

(6) The "One-stop" sub-project of "Ninth Five-Year Plan" of the National Economic and Trade Commission "Special refractory materials for dry quenching technology". 

In order to organize and implement the hard-won national refractory science and technology project and solve the problems of the whole refractory industry, the Ministry of Metallurgy attaches great importance to it. Breaking the departmental frame, organizing and mobilizing the power of the entire industry, led by the Ministry of Metallurgy, the United Nations National Building Materials Bureau and the China National Light Industry Council jointly organized and implemented two key scientific and technological projects in the "Eighth Five-Year Plan" and "Ninth Five-Year Plan". A leading group with Yin Ruiyu, an academician of the Chinese Academy of Engineering and Vice Minister of the Ministry of Metallurgical Industry as advisors (members of the chief comrades of the three departments), and an expert group with Mr. Zhong Xiangchong, an academician of the Chinese Academy of Sciences, as advisors have been established. The expert group is composed of well-known experts and professors in the refractory industry. Professor Wang Zetian and Yan Xingjian are the leaders of the expert group. Experts headed by Academician Zhong Xiangchong have done a lot of work and made important contributions to the outstanding completion of scientific and technological research projects.

These national science and technology projects are hosted by the Ministry of Metallurgical Industry (Bureau), the competent department of the industry, aiming at solving the products urgently needed by the industry (market), organizing superior forces in the entire industry including universities, scientific research, production, and users, and adopting the four "production, study, research and application" An integrated approach, aiming at the most advanced products and technologies imported and foreign, according to the characteristics of China’s refractory resources, realizing localization and forming production technology and key equipment with unique characteristics of China’s resources, and research in many important frontier fields Also made a breakthrough. Through the implementation, promotion, and application of these national scientific and technological projects, the overall level of China’s refractory industry has increased from the backward level in the 1960s and 1970s to the international advanced level in the late 1990s. Many of them were at that time. The international leading level of the company has achieved major development by leaps and bounds, kept up with the rapid development of high-temperature industries such as iron and steel, and achieved huge economic and social benefits. More than 95% of refractory materials used in steel, building materials, light industry and other industries have realized localization, ending the situation where most refractory materials are imported, and beginning to transform into a refractory powerhouse "from buying to selling". Well-known foreign refractory material groups (companies) have sold "bricks" to us at high prices in the past, and have begun to invest in China to establish production and research and development bases. During this period, China's refractory industry has achieved remarkable results in production equipment and technology, discipline construction, talent training, and the comprehensive strength of scientific research institutes and universities. Hundreds of units and hundreds of scientific and technological personnel in the industry have undertaken the tasks of these scientific and technological projects (projects or topics in the project, special topics, etc.), forming a batch of patented technologies, publishing papers, reports, and publishing works totaling more than one hundred articles (Ministry), has won hundreds of provincial and ministerial and national scientific and technological awards, and has cultivated a large number of industry-leading scientific and technological talents. It can be said that the "Eighth Five-Year" and "Ninth Five-Year" five-year plans are an important period of opportunity in the history of the development of China's refractory industry. The key turning period for the development of the link from the 20th century to the 21st century is a milestone. It has laid a solid foundation for the further development and improvement of China's refractory industry after entering the 21st century and to meet the continuous development needs of steel and other high-temperature industries.
