Why Buy Kerui Refractory Bricks?

Strict Production Process of Refractory Bricks

Screening of Raw Materials

The first step is to obtain the necessary raw materials, including alumina, mullite, silica, and so on. These materials are carefully selected based on their purity and quality to ensure the desired properties of the refractory brick.

Bricks Raw Material


The raw materials are mixed together in precise proportions to achieve the desired composition. The mixture of the refractory bricks is then molded into bricks through a molding process such as extrusion or pressing.

Kerui Forming of Buying Refractory Bricks


After forming, the refractory bricks are dried to remove moisture and ensure dimensional stability. The bricks are gradually heated to evaporate the moisture by controlling the temperature and airflow conditions.

Drying Kerui Fire Brick


Dry refractory bricks are fired in a high-temperature kiln. The firing process involves heating the bricks to a specific temperature. This step helps to sinter and fuse the raw materials, which results in a strong and durable structure.

Firing Fire Brick


Heating and cooling of refractory bricks refer to the gradual cooling of the kiln after the brick’s heating and firing process is complete. The cooled refractory bricks are then inspected for quality control to ensure they meet the standards.

Kerui Cooling of Good Fire Bricks


The final step includes packaging refractory bricks for shipping and distribution to customers or end users. The bricks are generally carefully packaged to prevent damage during handling and transportation.
