Manufacturing Process of Alumina Silicon Carbide Brick

1. Raw Material Processing System

The first step is to select high-quality raw materials for Al-SiC brick. Kerui quality inspection department will check the raw materials carefully and store them in partitions. At the same time, the fully automatic batching machine can realize accurate ratio of raw materials. Next, the batching equipment mixes the raw materials and pours them into molds.

2. Molding System

The mixed brick pulp will be pressed and molded by more than 20 sets of high tonnage press machines. Molded Al-SiC fire bricks will be measured and weighed for the second time to control the product quality.

3. Drying System

Molded Al-SiC bricks will be put on kiln cars and entered tunnel kilns for drying. Then drying system can effectively remove the moisture in the aluminum silicon carbide bricks and avoid cracking in the subsequent sintering process.

4. Sintering System

Sintering system has higher temperature to promote bonding of alumina silicon carbide bricks. Intelligent PLC controls monitor the position and temperature of more than 100 kiln cars in real time. The temperature fluctuation in the kiln is small and the product quality is stable.

5. Packaging and Delivery System

After cooling down, Kerui workers will pack alumina silicon carbide bricks carefully with wood tray, high-quality plastic film and steel belt. Meanwhile, our efficient team ensures on-time delivery.
