Low-porosity clay bricks
Description of low porosity clay bricks:
Low porosity clay bricks are made by firing refractory clay or charred gemstone clinker under high pressure and high temperature as the main raw materials. This product features high strength, low porosity, strong resistance to permeability and erosion. It is mainly used at the bottom of the regenerator in the glass melting furnace.
Advantage:
Low porosity and high density
Good dimensional stability
High mechanical strength
Strong wear resistance
Strong resistance to erosion
Good antioxidant property
High fire resistance
Good thermal shock stability
Good heat insulation performance
Application Scenarios：
| Industry | Specific Scenarios | Performance Requirements |
| Cement industry | Rotary kiln firing belts, cooler lattice bricks | Resistant to sulfate attack and thermal shock |
| Glass Furnace | Heat storage chamber latticework, melting section breast wall | Resistant to high temperature gas corrosion, anti-penetration |
| Iron and steel metallurgy | Ladle permanent layer, intermediate ladle working lining | Resistance to steel scouring, slag resistance |
| Waste incinerators | Furnace chamber lining, flue gas passages | Resistant to Cl-, SO₄²- corrosion |
