High-alumina anchor bricks are refractory bricks for heating furnaces. High-alumina anchor bricks are also called hanging bricks. They are mainly used to connect and support the structure of refractory bricks and ordinary sintered bricks and are used for heating furnace roof walls or other parts.
High-alumina anchor bricks are made of natural high-grade bauxite as the main refractory raw material, adding soft or semi-soft clay as a binder to the high-alumina clinker to start batching, mixing, molding, drying, and finally firing. Shaped high alumina refractory bricks. Generally, the alumina content of high-alumina anchor bricks is more than 55%. High-alumina anchor bricks can be produced and processed according to customer needs. The load softening temperature of high-alumina anchor bricks can reach 1550°C, which can meet the performance requirements of heating furnace roof lining.
Features of high alumina anchor brick for heating furnace:
1. Stable volume at high temperature.
2. Good corrosion resistance.
3. High softening temperature under load.
4. Anti-stripping and high compressive strength.
The high-alumina anchor brick is a special-shaped high-alumina refractory brick, which includes a column composed of a hanging end and an anchor body, and interval division grooves on the surface of the anchor body, along the length of at least one surface of the anchor body Ribs are set in the direction. Due to the reinforcement and pulling effect of the ribs, the tensile and flexural strength of the anchor is significantly improved. The stress generated at the groove is blocked by the ribs and cannot continue to be transmitted, so the high-alumina anchor bricks are not easy to break.
High-aluminum anchor bricks are refractory bricks for the furnace roof wall of the heating furnace. The size can be customized and processed according to the needs of the heating furnace to meet the needs of the lining of the heating furnace, ensure the service life of the lining of the heating furnace, and improve the economic benefits of the heating furnace.
