Reform and opening up more than 30 years, China's refractory industry has made great progress. China's refractory production ranks first in the world, refractory quality and variety has also been greatly improved and developed, refractory technology is also rapidly close to the international advanced level. However, China's refractory industry, there are still many problems, such as: high consumption of refractories; refractory production plants, low concentration; refractory product quality and poor stability; innovation is not enough; research and development work mainly concentrated in the material formula - composition - structure and performance, while the production process control and the use of refractory material is not enough attention.
At present, China's economic development has entered a transition period. Refractory users a large number of excess capacity, economic benefits, environmental requirements are increasingly stringent. These have caused great difficulties for refractory enterprises. The reasons for these problems are multifaceted, and the transformation of China's national economic development model, but also with the refractory industry itself is closely related to the problem. For example, the existence of a large number of small and medium enterprises that technological advantages and large-scale production advantages and did not give full play to the low level of small and medium enterprises to survive opportunities. The production of these problems and production management, scientific and technological progress and refractory workers thinking and other factors, can not be quickly resolved.
In the field of materials, refractories are a small, traditional branch, and it does not get enough attention. It is indispensable basic material of the national economy, but also the most complex microstructure of the material. It has the characteristics of multi-component, multi-particle and heterogeneous composite structure, and it is much more difficult to study the structure than other materials. Therefore, both from the number and depth of research than other materials behind, the development of science and technology is relatively slow. Looking back over the past half century, there are only two important technologies that affect the development of refractory materials.
