China's metallurgical industry will continue to develop steadily, the growth rate in quantity and scale will be slowed down, but in improving quality, developing varieties and reducing energy consumption are required to reach a higher level. Therefore, backward and old technology and equipment will be gradually eliminated, while the promotion and application of advanced technology and equipment will be accelerated. For example, in the iron and steel industry, basic furnaces and small blast furnaces, converters and electric furnaces will be phased out, while continuous casting and off-furnace refining will be developed and applied at a faster rate. Magnesia-chrome brick, magnesia-chrome brick, magnesia-pyroclay these conditions will provide new good opportunities for the development of refractory brick industry, but also put forward new and strict requirements for the quality of refractory brick, and will lead to more fierce competition among hundreds of refractory brick manufacturers in our country.
They all struggle for survival and development, and the decisive factors are as follows:
(1) the stability and reliability of product quality;
(2) to produce more efficient products with suitable price and competitive firebrick;
(3) Able to develop high-quality new products with better performance and provide good after-sales service.
It can be predicted that China's firebrick industry will adjust the product structure and increase the output of efficient products in the future. We should speed up the development of alumina - based high - efficiency products to further improve their quality and reduce costs. Competition between refractory bricks and amorphous materials, including prefabricated products, will continue in the future. The proportion of the production of amorphous materials will increase greatly, and the efficient castables will take the lead: in this respect, the micro-powder process; (preparation and application) should be a focus of research and development.
Considering the high temperature properties (mechanical properties, thermal shock resistance, corrosion resistance and oxidation resistance), the oxide and non-oxide composite is a promising new type of high quality and high efficiency firebrick, which may rise and develop gradually in the new century. This is a great area to explore, invest in, and develop. For China's firebrick industry, the beginning of the next century will be a period of structural optimization. Firebrick manufacturers will have to regroup and reorganize; Internal structure and management will be reformed; Variety structure will change; Process and equipment will be updated; The adaptability to the market economy will be improved. It is expected that by 2020, China's firebrick industry will catch up with the pace of the development of high-temperature industry and adapt to the pace of the international firebrick industry
