Foshan XINJIAYUAN is-Refractory Brick Home

Foshan XINJIAYUAN has a wide variety of refractory bricks, including clay refractory bricks, high alumina refractory bricks and special-shaped bricks.Here is an introduction to the clay refractory bricks in Shengyuan refractory bricks.

Clay refractory bricks, also called sintered bricks, are small man-made blocks used in construction. Clay bricks are made of clay (including powders such as shale and coal gangue) as the main raw material, which is processed, shaped, dried and roasted. , There is a difference between solid and hollow.

Clay refractory bricks are mainly composed of mullite (25%-50%), glass phase (25%-60%), cristobalite and quartz (up to 30%).Usually hard clay is used as the raw material, the mature material is pre-calcined, and then mixed with soft clay, which is formed by semi-dry or plastic method, and the temperature is 1300～1400 C to burn clay brick products.It is a refractory brick commonly used in blast furnaces, hot blast stoves, heating furnaces, power boilers, lime kilns, rotary kilns, ceramics and refractory brick firing kilns.

The main application of clay refractory bricks: widely used in metallurgy, building materials, chemical industry, petroleum, machinery manufacturing, silicate, power and other industrial fields.
