The Application Value of Refractory Materials

Refractory brick, as the important industrial product, has the performances of good heat resistance ability, large volume density, strong shock resistance.

Usually, refractory brick generally is divided into two types, namely unshaped refractory materials and finalize refractory materials. According to different material ingredients, and can be divided

into five categories, namely silica alumina refractory brick, alkaline series refractory brick, carbonic refractory brick, zirconium refractory brick, thermal insulation refractory brick.

Refractory brick is to use refractory clay or refractory raw materials firing into the refractory materials. Light yellow or brown. Refractory brick has a certain shape and size of refractory materials.




According to the preparation process method, can be divided into the burnt brick, unburned brick, fused brick (fused cast brick), fire-resistant insulating brick. According to the shape and size, can

be divided into standard brick, ordinary brick, special-shaped brick, etc.

Refractory brick can be used as building kiln and high temperature construction materials and structural materials of many thermal technology equipment, and can withstand various physical and

chemical changes in the heat and mechanical action. Such as refractory fireclay brick, high alumina brick, silica brick, magnesia brick, etc. Refractory rick is one of the most widely used in

refractory products, and what features does it have?

1. Chemical composition: the main ingredient decided the quality of refractory brick and characteristics.

2. Volume density: unit volume weight, density is big, shows that the compactness of refractory brick is good, the strength is likely to be high, but the coefficient of thermal conductivity could be big.

3. Apparent porosity: without specific requirements, but must strictly control the porosity.

4. Refractoriness under load: also called high temperature load starting deformation temperature, this parameter is very important, sign resistance to high-temperature of refractory brick.
