Industry Knowledge of Silicon Carbide Refractory Brick

Silicon carbide refractory brick is a type of special refractory materials made from silicon carbide raw materials using a special production process. This type of refractory products has a high temperature resistance and excellent abrasion resistance properties.

The classification of silicon carbide refractory brick is based on the content of silicon carbide in the raw material, as well as the composition of other materials. There are three main types: high-purity silicon carbide bricks, semi-graphite silicon carbide bricks, and graphite silicon carbide bricks. These three types differ in terms of their silicon carbide content and the addition of other materials, and each has its unique advantages.

The technical parameters of silicon carbide refractory brick include refractoriness, compressive strength, and thermal conductivity. Refractoriness refers to the temperature resistance of the bricks. It is determined by the melting point of the raw materials and the sintering temperature during production. The higher the refractoriness, the better the high-temperature resistance of the bricks. The compressive strength is the ability of the bricks to withstand deformation under compression, which is related to the raw material quality and sintering temperature. The higher the compressive strength, the better the wear resistance of the bricks. Thermal conductivity refers to the ability of the bricks to transfer heat, which is determined by the raw material properties.

The production process of silicon carbide refractory brick is mainly divided into raw material preparation, shaping, drying, and sintering. The high-purity silicon carbide bricks are produced using high-purity silicon carbide powder and ultrafine powder. Semi-graphite silicon carbide bricks are produced by adding graphite to the high-purity silicon carbide raw material. Graphite silicon carbide bricks are formed by adding graphite to the semi-graphite silicon carbide raw material.

In conclusion, silicon carbide refractory brick is an essential material in high-temperature industrial applications. Its various types and specifications provide solutions for different industrial needs, while its excellent technical parameters and production processes ensure its high performance and stability.
