PRODUCT DESCRIPTION

Introduction

High alumina brick is a high-quality, cost-efficient refractory brick with an alumina (Al₂O₃) content of more than 48%. Produced from premium bauxite raw materials through fine grinding, high-pressure molding and high-temperature sintering, this refractory brick delivers reliable and consistent high-temperature performance. Thanks to its excellent thermal stability, superior mechanical properties and competitive pricing, high alumina brick has become one of the most versatile and widely used general refractory materials for medium to high-temperature industrial furnace applications.

Key Features

• Excellent High-Temperature StabilityFeatures high refractoriness and outstanding load softening resistance. It maintains stable structural integrity under long-duration high-temperature operating environments without deformation or structural failure.

• Superior Thermal Shock ResistanceEffectively withstands frequent temperature fluctuations and thermal cycling. It resists cracking, peeling and spalling, ensuring long-term lining stability during continuous furnace operation.

• High Mechanical Strength & Anti-Scour PerformanceBoasts a dense, uniform brick structure with high compressive strength. It provides strong resistance against high-speed airflow scouring, material abrasion and mechanical impact.

Applications

Widely used for the upper, middle and lower linings of hot blast stoves, industrial heating furnace walls, steel ladles, tundish linings and other medium and high-temperature thermal equipment in metallurgical, chemical, power and building material industries.
