What should be paid attention to during the production process of refractory materials?

In the production of refractory materials, quality control and technical details are crucial. First, the selection of raw materials must strictly follow product performance requirements to ensure that the purity and particle size distribution of the raw materials meet the standards. This is the basis for ensuring the high-temperature stability and erosion resistance of refractory materials. Second, the mixing process must precisely control the ratio and mixing uniformity of each component to avoid performance degradation due to component segregation. During the forming process, appropriate forming methods such as pressing, isostatic pressing, or slip casting should be selected according to the shape and size of the product, and the forming pressure and temperature should be strictly controlled to ensure the density and uniform structure of the green body. In addition, sintering is a key link in the production of refractory materials. The sintering temperature and holding time must be precisely controlled to achieve the ideal phase composition and microstructure, thereby improving the refractoriness and mechanical strength of the product. Finally, product inspection and screening are equally important. Through strict physical performance testing and chemical analysis, it is ensured that each batch of products meets the specific needs and application scenarios of customers.

What are the standards for the use and testing of refractory materials?

The use and testing standards for refractory materials are crucial for ensuring that they can withstand high temperatures, resist erosion, and maintain structural stability in practical applications. In terms of use, the selection of refractory materials should be based on specific operating conditions, such as temperature range, atmosphere (oxidizing or reducing), mechanical stress, and chemical erosion. Different furnaces and processes have different performance requirements for refractory materials, so targeted material selection and design are necessary.

What are the characteristics of refractory materials?

Refractory materials possess diverse characteristics and exhibit unique properties under high-temperature conditions. Firstly, they demonstrate extremely high refractoriness, maintaining structural stability and integrity at high temperatures, resisting melting or deformation. This is crucial for high-temperature industries such as metallurgy, glass manufacturing, and ceramics. Secondly, they possess excellent thermal stability, withstanding rapid temperature fluctuations without cracking or damage, ensuring safe equipment operation. Furthermore, refractory materials typically exhibit good slag resistance and corrosion resistance, effectively resisting erosion from molten metals and slags, extending the service life of furnace linings. Simultaneously, their low thermal conductivity helps reduce heat loss and improve energy efficiency. In summary, refractory materials, with their superior high-temperature resistance and corrosion resistance, play an irreplaceable role in various high-temperature industrial fields.
