Features

Features

High Alumina Content for Extreme Refractoriness

With Al₂O₃ levels ranging from 48% to over 85%, these high alumina fire bricks provide superior resistance to chemical corrosion and thermal distortion in oxidizing or reducing atmospheres.

Thermal Load Stability at Elevated Temperatures

Designed to perform under temperatures exceeding 1450°C, each high alumina refractory brick maintains mechanical strength and structural integrity even under prolonged heat exposure.

Exceptional Thermal Shock Resistance

Manufactured through optimized particle grading and high-temperature sintering, Laurel high alumina fire bricks resist spalling, cracking, and deformation under frequent thermal cycling.

Low Impurities for Enhanced Purity and Corrosion Resistance

Each high alumina refractory brick is produced using raw materials with minimal iron and alkali content, ensuring long-term stability in contact with slags, molten metals, or corrosive gases.

Precision-Formed for Perfect Fit

As a leading high alumina bricks manufacturer, Laurel ensures every brick meets tight dimensional tolerances for easy installation, better heat retention, and longer refractory lining lifespan.
