What are the Specifications of High Alumina Straight Refractory Bricks

Specifications of high-alumina refractory bricks. High-alumina refractory bricks refer to a type of aluminum silicate refractory material with an alumina content of 48% or higher. They are made from bauxite or other high-alumina raw materials through forming and calcining. They have high thermal stability and a refractoriness above 1770°C. They also have excellent slag resistance. Contact Rongsheng Refractory for detailed dimensions of high-alumina refractory bricks.

Introduction to Special-Shaped High-Alumina Bricks

High-alumina special-shaped bricks are refractory products with specific, non-standard shapes, made primarily from high-alumina bauxite clinker through meticulous processing and specialized molding techniques. Their alumina content varies depending on the grade, typically ranging from 55% or higher. They are designed to meet the specialized refractory shape and performance requirements of complex structural components in various industrial furnaces. They occupy a crucial position within the refractory system and are a key material for lining specialized furnace sections.

Features of Special-Shaped High-Alumina Bricks

Customized Shapes: Precisely designed and manufactured to meet the structural and functional requirements of specific parts of the kiln, such as special shapes with various curvatures, grooves, and protrusions. This allows for a tight fit within the kiln structure, effectively preventing heat loss and material leakage, ensuring optimized overall kiln performance.

Excellent Refractory Performance: High refractoriness, typically reaching 1700°C to 1790°C, allows for long-term stable operation in high-temperature environments. Maintaining high temperatures within the kiln ensures smooth production processes.

High Corrosion Resistance: Highly resistant to high-temperature slag, molten metal, and gases. This effectively reduces material loss and structural damage caused by chemical attack, extending the kiln's service life and maintenance intervals.

High Structural Stability: Despite its unique shape, it maintains high mechanical strength, including excellent compressive and flexural strength. It can withstand various forces during kiln operation, including thermal and mechanical stresses and material impact, while maintaining its shape and structural integrity.

Uses of Special-Shaped High-Alumina Bricks

Steel Smelting Furnaces: Used in blast furnace cooling staves, hot blast furnace burners, and hot blast duct elbows and reducers. They precisely conform to the shape requirements of these complex areas, protecting the furnace structure from the intense erosion and erosion of hot molten iron, slag, and high-temperature airflow, ensuring the efficiency and safety of the steelmaking process.

Glass Melting Furnaces: Used in specialized areas such as the charging port, flow hole, and kiln sill, which place extremely high demands on the shape and performance of the refractory material. High-alumina special-shaped bricks can withstand the high-temperature erosion and long-term erosion of molten glass, maintaining stable operation of the glass melting furnace and guaranteeing the quality and yield of glass products.

Ceramic Kilns: Used in areas such as the exhaust vents, temperature measurement holes, and burner bricks of ceramic tunnel kilns, their special shapes meet the requirements of kiln ventilation, temperature measurement, and combustion processes. Furthermore, their excellent refractory and erosion resistance provide a stable high-temperature environment for firing ceramic products, helping to improve the firing quality and yield of ceramic products.

Other high-temperature industrial furnaces: These include reactors in the chemical industry, nonferrous metal smelting furnaces, and other specialized structural components. High-alumina special-shaped bricks leverage their adaptable shape and excellent performance to ensure the proper operation of the furnace and the stable implementation of production processes. They play an indispensable role in numerous high-temperature industrial production processes.
