Fireclay refractory brick High temperature high refractoriness refractory materials

Product Description

Specifications
Al₂O₃: ≥ 36%
Size: 230 × 114 × 65 / 75 mm or customized dimensions

Fireclay bricks are dense shaped refractory materials with high refractoriness and excellent mechanical strength at elevated temperatures. They are essential materials for high-temperature applications and are widely used in industrial furnaces, kilns, and other thermal processing equipment.

Fireclay bricks have a wide range of applications in industries such as metallurgy, construction (cement and glass), petroleum, chemical processing, power generation, and machinery manufacturing.

Application

Fireclay bricks are available in various specifications and dimensions. They are widely used in glass furnaces, blast furnaces, hot-blast stoves, cement kilns, chemical furnaces, and other high-temperature thermal equipment.
