Product Description
High Strength Fire Refractory Bricks with Thermal Shock Resistance
Designed as anchor bricks for high temperature furnace applications, these specialized refractory components provide secure mechanical attachment with unique anchoring features.
Product Overview
Alumina anchor bricks are engineered with high aluminum oxide content (typically 70-85%) and incorporate integrated hooks, lugs, or dovetail designs that interlock with furnace structures and insulating linings. The specialized anchoring system eliminates the need for separate metal anchors, reducing thermal conductivity points and preventing localized heat loss.
With high cold crushing strength (80-100 MPa) and excellent thermal shock resistance, alumina anchor bricks maintain structural integrity during rapid temperature changes while their low porosity (15-22%) minimizes heat transfer and improves overall furnace energy efficiency.
Key Advantages
The primary advantage lies in the innovative one-piece construction that combines structural support and refractory properties in a single unit. By eliminating traditional metal anchors, these bricks prevent galvanic corrosion and thermal expansion mismatches that commonly cause lining failures in high-temperature environments.
The ceramic-based anchoring system provides superior resistance to oxidation and chemical attack compared to metal fasteners, significantly extending service life. Their high alumina content ensures excellent resistance to slag penetration and chemical corrosion, while the integrated design reduces installation time and labor costs by up to 40% compared to traditional anchor systems.
