High-alumina mullite refractory bricks, produced by a leading global refractory manufacturer, are specifically designed for dry coke quenching systems and can withstand long-term, stable service in extreme temperatures exceeding 1200°C. Primarily composed of high-quality mullite (3Al₂O₃·2SiO₂), these bricks utilize advanced sintering or electrofusion processes to achieve high refractoriness, excellent refractoriness under load, low high-temperature creep, and outstanding resistance to thermal shock and acidic slag corrosion. These bricks meet the core needs of international customers for long-life, low-maintenance refractory materials. They are widely used in key areas such as steel mill dry coke quenching units, hot blast furnaces, converter ladle cars, electric arc furnaces, ceramic kilns, glass regenerators, and cement rotary kilns, helping customers improve energy efficiency, extend lining life, and reduce operational risks. Their stable and reliable quality, meeting export standards, makes them a preferred solution for customers in the global metallurgical, building materials, and glass industries.
1. The main crystal phase structure of mullite gives it extraordinary thermal shock resistance and adapts to frequent temperature changes;
2. High aluminum content (>75%) enhances high temperature strength and corrosion resistance;
3. Both electric melting and sintering processes are optional, flexibly adapting to different usage scenarios;
4. Low apparent porosity and high bulk density, reducing heat loss;
5. Strict quality inspection before shipment to ensure batch consistency and compliance with international certifications.
Suitable for high-temperature industrial equipment such as dry coke quenching systems in the steel industry, cement rotary kilns, glass melting furnace regenerators, ceramic firing tunnel kilns, and electric arc furnace linings. Primarily targeting global steel, building materials, and glass manufacturers, this product is particularly well-suited for buyers seeking energy conservation and consumption reduction, extended kiln life, and reduced downtime for maintenance.
