China’s metallurgical industry will continue to develop steadily, and the growth rate will be slower in terms of quantity and scale, but higher levels are required in terms of improving quality, developing varieties and reducing energy consumption. Therefore, backward and obsolete crafts and equipment will gradually be eliminated, and advanced technology and equipment promotion and application will accelerate. For example, in the steel industry, furnaces and small blast furnaces, converters and electric furnaces will be eliminated, while continuous casting and refining will be developed and promoted at a faster rate. These conditions will provide new and good opportunities for the development of the refractory brick industry, and also put forward new and strict requirements for the quality of refractory bricks, and will lead to more intense tens of refractory brick manufacturers in China. competition.
They must fight hard to survive and develop, and the decisive factors are as follows:
(1) Stability and reliability of product quality;
(2) Producing more efficient and competitive high-efficiency products for refractory bricks;
(3) Ability to develop high-quality new products with better performance and provide good after-sales service.
It is foreseeable that in the future, China’s refractory brick industry will adjust its product mix and increase the output of high-efficiency products. The development of high-efficiency products based on bauxite should be accelerated to further improve their quality and reduce costs. The competition between refractory bricks and amorphous materials (including preforms) will continue in the future. The production ratio of amorphous materials will increase greatly, and high-efficiency castables will take the lead: in this respect, the micro-powder process; (preparation and application) should be a focus of research and development.
Considering high temperature performance (mechanical properties, thermal shock resistance, erosion resistance and oxidation resistance), oxide and non-oxide composite materials are promising new high-quality and high-efficiency refractory bricks, which may rise in the new century. And gradually developed. This is an area worth exploring, investing in and developing. For China’s refractory brick industry, the beginning of the next century will be a period of structural optimization. Refractory brick manufacturers will be re-combined and adjusted; internal structure and management will be reformed; variety structure will be changed; process and equipment will be updated; adaptability to market economy will be improved, and it is expected that China’s refractory brick industry will catch up with high temperature by 2020 The pace of industrial development, and can adapt to the rhythm of the international refractory brick industry market.
