China's glass industry is developing rapidly, and has become the world's first glass production power. The rapid development of the glass industry naturally promotes the development and technological progress of China's glass furnace refractory materials. Compared with the traditional process, modern glass production technology has a qualitative leap which towards the direction of higher efficiency, lower energy consumption and better product quality. Accordingly, the technical level of glass furnace which is as the core equipment of glass production is also in constant progress, for instance, widely adopt new technologies to improve the combustion intensity, strengthen heat transfer effect, reduce heat loss and educe the pollution of products and environment.
The technological progress of glass furnace requires a variety of high quality refractory bricks as the guarantee condition which can withstand high temperature, resist to strong chemical corrosion and bear severe stress damage. In order to achieve the new furnace technology of high efficiency, energy saving and low pollution, it is very important to combine and use several kinds of high quality refractory in one glass furnace, for example, fused cast AZS brick 33# is mainly used in relatively low temperature and corrosive parts of glass furnace such as working ends, feeder channel; fused cast AZS brick 41# is especially applied to seriously corrosive parts of glass furnace such as throat, bottom budding, dam brick, electric brick corners, doghouse and also can be used in sidewalls; Zircon brick is mainly used in the superstructure of flame space and tank bottom of glass furnace; fused cast alumina brick (α-β brick) is mainly used as the ideal refractory material for feeder channel, spouts and working ends of glass furnaces.
Go through years of work and the efforts of all aspects, the glass refractory in China has made significant progress, greatly narrowed the gap with foreign, laid a more solid foundation for enterprise development. As long as the next step to strengthen macro management, concentrating in taro in error problem to solve, we can make greater contributions to the development of glass industry.

;D China's metallurgical industry will continue to develop steadily, in the number of scale growth rate will slow down, but in improving quality, develop varieties and reduce energy consumption are required to achieve a higher level. Therefore, backward, old technology and equipment will be gradually eliminated, and advanced technology and equipment to promote the application will be accelerated. For example, in the iron and steel industry, furnace and small blast furnace, converter and electric furnace will be eliminated, and continuous casting and furnace refining will be faster and development and application. These conditions will provide a new and good opportunity for the development of refractory bricks, as well as new and stringent requirements for the quality of refractory bricks and will lead to more intense use among hundreds of refractory tiles manufacturers in China competition.
They have to struggle to survive and develop, and the decisive factors are as follows:
(1) product quality stability and reliability;
(2) the production of more refractory bricks affordable, competitive and efficient products;
(3) the ability to develop a better use of high quality new products, and provide good after-sales service.
It is foreseeable that the future of China's refractory industry will adjust the product structure, increase the production of highly efficient products. We should accelerate the development of efficient bauxite products, further improve their quality and reduce costs. The competition between refractory bricks and unshaped materials (including preforms) will continue in the future. The proportion of production of amorphous materials will be greater growth, and efficient castables will lead the position: in this regard, the powder process; (preparation and application) should be a research and development as a focus.
Considering high temperature performance (mechanical properties, thermal shock resistance, corrosion resistance and oxidation resistance), oxide and non-oxide composite materials is a promising new type of high quality and high efficiency refractory bricks, which may rise in the new century And gradually developed. This is a field that is worth exploring, investing and developing. China's refractory brick industry, the early next century will be the structure of the optimization period. Refractory brick manufacturers will be re-combination and adjustment; internal structure and management will be reformed; variety structure will change; technology and equipment will be updated; the adaptability of the market economy will be improved by 2020 China's refractory brick industry will catch up with high temperature Industrial development pace, but also to adapt to the international market trend of refractory bricks.
