Research significance and development trend of new refractory materials

 In recent years, the promotion of new processes and technologies in steel production, as well as the requirements for energy saving and environmental protection, have put forward more special requirements for new refractory materials. From the perspective of future development trends, new refractory materials will include high-performance structural refractory materials and functional refractory materials.

 The significance of studying new refractory materials

 The energy consumption of my country's steel industry is relatively high. The energy consumption per ton of steel produced is 20% to 40% higher than the international level and 320 kg of standard coal higher than Japan. It can be seen that my country's steel industry has high energy consumption and huge potential for energy saving and consumption reduction. Therefore, it is of great significance to do a good job in energy saving and consumption reduction to improve the competitiveness of my country's steel industry. 

In the past 20 years, the output and varieties of my country's steel industry have greatly developed. In order to adapt to this development, China's refractory materials continue to be updated and upgraded, and the variety has been added to more than 10 major categories with a total of more than 100 brands, changing the traditional traditional clay, high aluminum, silica, and magnesium products. The structure of the four major categories. According to the development focus of the iron and steel industry, although the steel output will not increase significantly, the continuous casting ratio and refining ratio of steel will continue to increase, and the equipment will continue to be large-scale and modernized. These characteristics of the development of the iron and steel industry have prompted refractory materials to continue to improve product quality and expand varieties. At the same time, around energy conservation and consumption reduction, some refractory materials with specific functions have been produced.

The development trend of new refractory materials

In recent years, the promotion of new processes and technologies in steel production, as well as the requirements for energy saving and environmental protection, have put forward more special requirements for new refractory materials. From the perspective of future development trends, new refractory materials will include high-performance structural refractory materials and functional refractory materials.   

1. Structural refractories

The general development trend of structured refractory materials will be high purity, densification, precision, the popularization of carbon-containing refractory materials, compounding and indefinite formation of oxide and non-oxide materials. In particular, unshaped refractory materials will have a large application market in the next period of time, because it has the advantages of short production cycle, energy saving, good integrity, strong adaptability, and good comprehensive use effect.  

2. Functional refractories  

Functional refractory materials include high-performance thermal insulation refractory materials, high emissivity energy-saving coatings, high thermal conductivity and high conductivity refractory materials, high-performance rapid heat storage refractory materials, etc.
