Analysis and Comparison of Refractory Bricks for Incinerators at Home and Abroad

Refractory material is essential basic materials in high temperature industrial. Its main users such as steel, cement, glass, non-ferrous metal industry, etc. In order to meet the energy consumption and environmental protection requirement, our need meet new type refractory material.

Refractory is an indispensable basic material for high temperature industries. The development of important pillar industries of the national economy such as steel, nonferrous metals, building materials, chemicals, and machinery are closely related to the development and progress of refractory materials. The development of refractory materials industry has become one of the basic conditions for the development of the national economy. The rapid development of high-temperature industries, especially the metallurgical industry, has led to the rapid development of China's refractories industry. This is not only reflected in the first production and consumption of refractory materials in China, but also reflected in the comprehensive improvement of China's refractory technology. China is a major producer of light-weight fireclay insulation bricks and its output is far ahead in the world.

The refractory industry in Europe and Japan has a similar situation: consumption is reduced, total volume is reduced, and quality and service life are still increasing. The Japanese steel industry is the main user of refractory materials, and its usage accounts for nearly 70% of the total. Affected by changes in recent years, such as restructuring, reducing staff, strengthening the development of high-grade steels and special steels to improve international competitiveness, the Japanese refractories industry is also adapting to the requirements and strives to improve the three properties of refractory use-durability, reliability, construction, at the same time, withstand price reductions and meet environmental protection requirements.

On the one hand, the technological development of the main users of refractory materials such as steel, cement, glass, non-ferrous metals and other industries has put forward higher quality and variety requirements for refractory materials. On the other hand, in these fierce quality and price competitions, these industries have imposed severe requirements on refractory materials to reduce the cost of refractory materials per ton of products, causing refractories companies to accelerate the development and development of new high-quality products with greater investment. Optimize and save raw materials and energy, develop new, high-efficiency, compact, low-emission, clean new production processes for unshaped and shaped refractories, and expand the production and development space of the insulating brick suppliers.

Facing the current status of China's refractory industry, China's refractory industry must be guided by domestic and foreign markets, meet the needs of high-temperature industrial development in terms of variety, quality and quantity, aim at the frontier science and technology of the world's refractories, and accelerate the improvement of the industry's independent technological innovation capabilities，and strive to build refractory production technology and variety series with Chinese characteristics, to better serve the steel, cement, glass, non-ferrous metals and other industries.
