The fire clay bricks manufacturing process includes seven steps.

fire ckay bricks

1) Obtain raw materials. The clay for manufacturing bricks is obtained from the ancient soil deep under the earth’s surface. The soil in this layer is slightly deeper in color than the topsoil and was formed about 80,000 to 120,000 years ago. At that time, the climate is warm and humid and plants are diverse and lush , which mades the soil in this period soft and sticky and a good raw material for fireclay bricks.

2) The clay is stacked in the open air for up to six months to make its inner structure loose. Then it is crushed and screened to get the pure fine clay.

3) Add water to the clay and then repeat kneading to make it into thick mud. This step is very important for the finished products.

4) Puur the mud into the mold. Compact it and then remove the remaining mud with a wire bow.

5) Release the green body from the mold and dry it in the shadow to avoid cracks and deformation caused by exposure to the sun.

6) After drying, fire bricks in the kiln. This process is the most important part of the brick-manufacturing process.

7) After ten days of firing, the green body is basically sintered. if stopping heating at this time, the outside air may come into the kiln and make the bricks oxidized into red bricks. in order to prevent oxidazing, seal the kiln roof with clay.

Fire clay brick accounts for an important position in the refractory industry. The most important feature of fire clay brick is that the raw materials can be obtainded locally.

Fire clay brick is cheap and durable. It can be used for fire protection, thermal insulation, sound insulation and moisture absorption. Therefore, it is widely used in industrial production. The scrap bricks can be reused as aggregate.

When purchasing fire clay bricks, some professional knowledge is needed and some principles should be followed.

1) Take your need into account, such as specifications and materials.

2) Select appropriate manufacturers. Shop around and capare the price before you buy. Also pay attention to the credibility of manufacturers, after sales service, product quality and service attitude.

3) After selecting a manufaturer, give a visit to the factory to understand the strength of manufacturers, scale, production qualification, production capacity and evaluation on the product from other customers.
