Fire clay bricks manufacturing process

Generality High Alumina Brick &Clay Brick

The fire clay bricks manufacturing process includes seven steps.

1)Obtain raw materials. tundish well block 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 Clay, High Alumina insulating bricks 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 zirconium sizing nozzle 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. tundish coating 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.
