We promise to provide you with high-quality refractory materials.
Product description of fire clay bricks
Fire clay bricks, also known as sintered bricks, are small artificial blocks for building. Clay bricks are made of clay as the main raw material through mud treatment, molding, drying and baking. They are solid and hollow.

Our company
On the basis of the production of ordinary clay bricks, the clay bricks produced by our company use good homogenizing materials as the main raw materials, add appropriate auxiliary materials and some additives, after fine grinding, mixing, high-pressure molding, and transform into mullite crystal phase at an appropriate firing temperature, so that the products have good mineral composition, so as to ensure that the products have high refractoriness, dense bulk density, low porosity Excellent high temperature creep property and good volume stability.
We support custom-made special-shaped clay refractory bricks, which can be customized according to drawings.
