If you’re seeking a high-performance lining material, this guide covers the essential advantages, applications, and maintenance tips for Corundum Brick—and why leading industries choose it for operational excellence.

Why Choose Corundum Brick? Core Advantages

Manufactured from premium-grade aluminum oxide (Al₂O₃), Corundum Brick delivers exceptional performance in the harshest thermal environments:

Outstanding Thermal Endurance – Withstands temperatures up to 1800 °C (3272 °F), making it ideal for ultra-high-heat processes.

Superior Mechanical Strength – High compressive strength allows Corundum Brick to resist cracking and deformation under heavy loads.

Excellent Thermal Shock Resistance – Maintains stability through rapid heating and cooling cycles.

Chemical & Slag Corrosion Resistance – Resists acidic and alkaline attacks, extending service life in metallurgy, cement, and glass industries.

Extended Service Life – Reduces downtime and maintenance costs compared to standard refractory products.

Technical Index

Key Applications of Corundum Brick

Steel & Metallurgy – Blast furnaces, ladles, electric arc furnaces. Corundum Brick protects against molten metal and slag erosion.

Petrochemical & Refining – Cracking furnaces, reformers, incinerators. Resists corrosive gases and thermal shock.

Cement & Lime Kilns – Burning and transition zones. Handles extreme abrasion and clinker build-up.

Glass Manufacturing – Tank furnaces and regenerators. Prevents contamination in high-silica environments.

Power Generation & Waste Incineration – Boilers, chimneys, thermal reactors. Maintains long-term thermal insulation.

Installation & Maintenance Best Practices

Pre-Installation – Inspect each Corundum Brick for cracks; store in dry conditions.

Laying – Use high-temperature mortar and follow expansion gap guidelines (3–5 mm).

Curing & Heating – Gradually heat to avoid thermal shock; follow proper annealing schedules.

Ongoing Maintenance – Inspect regularly; replace damaged Corundum Brick promptly to maintain performance.
