Product Description
Product Overview
Leadsun supplies several grades of insulating fire brick for use in applications ranging from 1260 °C to 1760 °C. Each grade is formulated to meet specific thermal and physical requirements. After firing, every brick is machined to close dimensional tolerances.
Insulating bricks are manufactured using exceptionally high-purity clays and other ceramic materials. Carefully graded organics used during the manufacturing process burn out during firing to create a uniform pore structure.
Applications
- Primary hot face linings
- Back-up insulation for furnaces and kilns
- Flue insulation
- Sulphur recovery equipment
- Hot blast stoves
Key Features
- High insulating properties
- Strong compressive strength
- Low heat storage
- High purity
- Tight dimensional tolerance
- Energy saving
- Low impurities
