The Application Value Embodiment of Refractory Brick

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.

5. Thermal shock resistance: resistance to the ability of rapid changes in temperature and not be damaged.

6. Compressive strength: bear (room temperature) the maximum pressure ability.

7. Flexural strength: bear shear pressure ability.
