Utilization Scenarios of Fire Clay Insulation Brick

Due to its excellent insulation and thermal stability, it is widely used for kiln insulation layers, linings, flues, pipes, and other high-temperature equipment. It is mainly used in the following fields:

• Steel industry: Steelmaking furnaces, converters, electric furnaces, refining units, etc.
• Non-ferrous metals industry: Smelting furnaces, aluminum electrolysis furnaces, heating furnaces, gas furnaces, homogenizing furnaces, annealing furnaces, etc.
• Building materials industry: Glass furnaces, cement kilns, lime kilns, building walls, etc.
• Chemical industry: Industrial kilns, reactors, pipelines, storage tanks, etc.
• Other industries: Boilers, chimneys, etc.

Kerui – Top Fire Clay Insulation Brick Manufacturer

• Factory: The factory covers an area of 20,000 square meters. The factory has a digital automation management system;
• Certificates: Multiple certificates (ISO, CE, etc.), patents and other enterprise certificate of honor;
• Rich production experience: 20+ years of production experience;
• Full export experience: Export experience in 50+ countries;
• Rich industry experience: Multiple kiln insulation solutions.

• Low thermal conductivity: Its thermal conductivity is between 0.23 and 0.65 W/(m·K). The thermal conductivity is much lower than that of ordinary bricks. This brick can prevent heat transfer.
• High porosity: The porosity is between 40 and 70%. This enhances the insulation effect.
• Strong thermal shock resistance: Its permanent linear change is between -2 and 1%. The clay insulation bricks will not crack under large temperature changes.
• Good insulation effect: Due to its low thermal conductivity, high porosity, and other characteristics, this brick has a good insulation effect. It can effectively improve energy efficiency.
• Low bulk density: Its density is between 0.5 and 1.5 g/cm³. Lightweight clay insulation bricks are lightweight. It can reduce the structural load of high-temperature buildings.
