1. What Is an Anchor Brick
Anchor brick, also known as hanging refractory brick, is a special-shaped refractory component designed for anchoring and suspending industrial furnace linings. Manufactured from high-purity bauxite through high-temperature sintering, it effectively solves common lining failures such as loosening and displacement on furnace tops, vertical walls, and flue systems. Unlike standard refractory bricks, its unique grooved and perforated structure provides strong clamping force to fix insulation layers and castables securely, serving as an essential structural part for all high-temperature furnace equipment.
2. Core Performance Advantages
Our high-performance anchor bricks are engineered for long-term service in harsh high-temperature environments. With an alumina content ranging from 55% to 75%, they deliver excellent thermal stability, spalling resistance, and corrosion resistance under continuous extreme heat. Made by mechanical pressing and high-temperature firing, these bricks feature high compressive strength and superior wear resistance. They effectively prevent lining cracking, peeling, and sagging caused by frequent temperature changes. Their adaptive structure accommodates furnace thermal expansion and contraction, extending lining service life and greatly reducing operational and maintenance costs.
3. Industrial Application Scope
Anchor bricks are widely used in various high-temperature industrial sectors. They act as core anchoring and supporting materials for cement rotary kilns, glass melting furnaces, industrial heating furnaces, and blast furnaces. They are also suitable for roof linings, furnace arches, side walls, and flue tops in metallurgical, petrochemical, and thermal power equipment. Ideal for both new furnace construction and old lining renovation, our anchor bricks provide reliable structural support and stable thermal insulation for high-temperature refractory systems.
