Corundum Refractory Bricks
Ruitai Lianxin corundum refractory bricks are high-performance refractory materials manufactured using high-purity alumina (Al₂O₃ content ≥ 90%; for high-purity grades, content ≥ 99.5%) as the primary raw material, sintered at ultra-high temperatures through advanced production processes. As a critical refractory brick type, corundum refractory bricks are widely utilized across various high-temperature industrial sectors—distinguished by their exceptional performance—to provide reliable protective safeguards for industrial kilns and equipment.
Characteristics of Corundum Bricks
As a professional refractory bricks manufacturer, our corundum bricks have become the preferred choice for carbon black reactors, glass kilns, and petrochemical plants, thanks to the following four core performance advantages:
◉ Extreme Temperature Resistance;
◉ Exceptional Slag & Chemical Corrosion Resistance;
◉ Superior Mechanical Strength & Hardness;
◉ Excellent Volume Stability & Thermal Shock Resistance.
Widespread Application Scenarios for Corundum Bricks
As a versatile refractory brick product, corundum bricks are widely utilized across various high-temperature industrial sectors; Ruitailianxin consistently provides reliable refractory solutions to clients worldwide.
Metallurgical Industry
Primarily utilized for constructing the linings of electric arc furnace bottoms, ladle slag lines, RH vacuum degassing units, and the impact zones of continuous casting tundishes; it effectively withstands the erosion caused by molten steel, thereby significantly extending the service life of the equipment.
Glass Industry
Applied to components within glass melting furnaces, such as forehearths, risers, feeder channels, and charging ports. By virtue of its low-contamination characteristics and exceptional corrosion resistance, it helps minimize “stone” defects in glass products, thereby enhancing overall product quality.
Cement Industry
Corundum bricks are primarily utilized in critical areas such as the burning zone of rotary kilns, the high-temperature zones of coolers, and tertiary air ducts; if chrome-corundum refractory bricks are selected, they offer exceptional resistance to alkali corrosion.
Steel Industry
Corundum bricks primarily serve as lining materials for furnace equipment such as converters, electric arc furnaces, heating furnaces, and continuous casting tundishes. These corundum refractory bricks are capable of withstanding high temperatures ranging from 1600°C to 1800°C, as well as the erosive action of molten steel and slag, thereby ensuring the stable operation of the furnaces.
Other High-Quality Composite Corundum Bricks
In addition to standard corundum bricks, Ruitailianxin also manufactures a range of composite corundum refractory bricks, including corundum-mullite refractory bricks, chrome-corundum bricks, and sintered zircon-corundum bricks.
Corundum-Mullite Brick:
A composite corundum brick manufactured using high-purity corundum and mullite as primary raw materials, formed under high pressure, and sintered at high temperatures; its Al₂O₃ content ranges from 70% to 88%.

Long-term service temperature of 1650–1700°C;
Possesses excellent thermal shock stability (≥10 cycles of water quenching from 1100°C);
Exhibits strong resistance to acid and alkali slag corrosion.
Application Areas:
Metallurgical heating furnaces, glass melting furnace regenerators, and cement rotary kiln transition zones.
Chrome Corundum Brick
High-performance composite corundum bricks, composed of high-purity corundum (Al₂O₃ ≥80%) and chromium oxide (12%–20%), form a stable solid-solution structure after high-temperature sintering.
Product Features:
Possesses extremely high refractoriness (>1790°C);
Exhibits exceptional resistance to slag erosion;
High mechanical strength.
Application Areas:
Glass furnace tank walls, slag line zones of steelmaking converters, metallurgical flues and furnaces, and high-temperature zones of waste incinerators.
Sintered Zirconia-Corundum Brick:
A high-end composite corundum brick manufactured using high-purity corundum (Al₂O₃ ≥ 60%) and zirconia (15%–40%) as raw materials, produced through a process of precise batching and high-temperature sintering.
Features:
Refractoriness ≥ 1800°C;
Possesses excellent thermal shock stability;
Exhibits good volume stability at high temperatures.
Application Areas:
Glass furnace tank walls, steelmaking converter slag lines, metallurgical volatilization kilns, and waste incinerators.
