Product Description
Clay Refractory Bricks for Industrial Applications
Clay refractory bricks are high-temperature resistant products manufactured with alumina content ranging from 30% to 48%. These bricks utilize clay clinker as aggregate and refractory clay as binder, providing exceptional thermal insulation and durability for demanding industrial environments.
Material Composition & Manufacturing
The production process utilizes two primary clay types: hard clay (calcined as clinker) and light clay (used as binder for plasticity). Key clay minerals include kaolinite (Al₂O₃·2SiO₂·2H₂O), dickite, montmorillonite (Al₂O₃·4SiO₂·6H₂O), and mica minerals.
Industrial Applications
These refractory bricks are widely used across multiple industries due to their cost-effectiveness and reliable performance:
- High temperature furnaces and hot blast furnaces
- Ironmaking furnaces and ladle systems
- Foundry casting systems and soaking furnaces
- Reheating furnaces and non-ferrous metal melting furnaces
- Silicate and chemical industry kilns
- Industrial chimney systems and thermal equipment flues
