【Product Features】
Strong Structural Stability
The internal structure of the brick is dense, with a flexural strength of ≥10MPa and a compressive strength of more than 70MPa. It does not crack or deform during thermal cycles, ensuring the long-term stability of the lining structure.
High Refractoriness
Refractory anchoring bricks use more than 85% high-aluminum raw materials, sintered at high temperature, with a refractoriness of 1750℃, and can work in high-temperature kilns, heat treatment furnaces and other environments for a long time.
Accurate Size
The size error is controlled by CNC precision machining to ±0.2mm, and the installation alignment is tighter, effectively improving the sealing and safety of the overall structure.
Corrosion Resistance
Refractory anchoring bricks are made of dense corundum or mullite, which effectively resists furnace gas, slag and acid and alkali corrosion.
【Frequently Asked Questions】
Q: In which industries are refractory anchoring bricks mainly used?
A: Refractory anchoring bricks are mostly used in metallurgy, chemical industry, electric power and other industries. They are indispensable for the lining fixation of high-temperature equipment such as blast furnaces, kilns, boilers, etc.
Q: How to clean the surface of refractory anchoring bricks?
A: To clean the surface of refractory anchoring bricks, you can use a brush to remove floating dust, and use compressed air to blow stubborn stains. Avoid washing with water to prevent moisture from affecting performance.
Q: What preparations should be made before installing refractory anchoring bricks?
A: Before installation, check whether the brick body is intact, clean the impurities on the installation surface, determine the position according to the design, and prepare the matching adhesives or fixings.
Q: What should be paid attention to in the transportation and storage of refractory anchoring bricks?
A: Avoid collision damage during transportation, and store them in a dry and ventilated place to prevent moisture and stay away from corrosive substances such as acids and alkalis.
