Brief Introduction of Light Clay Refractory Brick

Lightweight clay refractory bricks are mainly used in industrial furnaces. They are made of clay and go through a series of processes such as batching, molding, drying and firing to create this porous and lightweight material.

What are the advantages of lightweight clay refractory bricks?

• Lightweight: Lightweight clay bricks have a volume density of 0.5-1.3g/cm³, which is more than 20% lighter than standard clay bricks. They can reduce the overall weight of high-temperature kilns and reduce transportation costs.
• High Strength: These bricks have strength grades of MU3.5-MU10, which can meet various construction requirements.
• Thermal Insulation: The microporous structure contains a large number of air pockets, which enhances thermal insulation by minimizing heat transfer.
• Easy to install: Lightweight clay tiles can be easily handled and installed using traditional building methods as they are similar in size and shape to traditional clay tiles.

Production process of lightweight clay refractory bricks

The production process of lightweight clay bricks involves several steps including batching, molding, drying, and firing.

1. Batching: This critical stage involves formulating the product based on product specifications and raw material properties. The main materials usually include clay, shale and gangue, with appropriate additives and modifiers added as needed.
2. Molding: Molding is an important stage in brick forming. Commonly used molding techniques include pressing, vibration, extrusion, etc.
3. Drying: After forming, the bricks are dried to remove moisture and volatile substances. Common drying methods include natural drying and heat-assisted drying.
4. Firing: The final step is to heat the dried bricks at high temperatures to achieve a stable crystal structure. The temperature and time need to be carefully controlled to meet the requirements of different products.
