Product Introduction
Alumina ceramic liners and guide rail components are specialized industrial ceramic products made from high-purity alumina (Al₂O₃). Through advanced forming and sintering processes, these products exhibit extremely high hardness, excellent wear resistance, and outstanding corrosion resistance. The surface precision can reach Ra0.2μm, with dimensional tolerances controlled within ±0.01mm, making them ideal wear-resistant components for heavy-duty equipment and precision machinery.

Main Applications

• Mining machinery: Conveyor guide rails, crusher liners, screening equipment wear parts

• Power industry: Coal mill liners, coal conveying system guide rails, fan blade protection sleeves

• Steel metallurgy: Roller guide rails, continuous casting machine liners, high-temperature conveyor belt supports

• Cement production: Raw material mill liners, elevator guide rails, cyclone inner liners

• Port machinery: Ship unloader liners, conveyor belt rollers, ship loader guide rails

• Chemical equipment: Reactor wear-resistant linings, agitator protection sleeves, pipeline linings

Product Advantages

• Exceptional wear resistance: Hardness ≥88 HRA, wear resistance is 10 times higher than that of high manganese steel

• Corrosion resistance: Resists acid and alkali corrosion, suitable for harsh working conditions

• High-temperature performance: Long-term use temperature up to 1500°C without deformation or softening

• Low friction coefficient: Dynamic friction coefficient of 0.1–0.15, reducing operational resistance

• Insulation performance: Volume resistivity >10¹⁴ Ω·cm, ensuring operational safety

• Easy installation: Can be installed via bonding, welding, or mechanical fixation

FAQ

Q: What is the service life of ceramic liners?
A: Under the same working conditions, their lifespan is 5–8 times longer than that of manganese steel liners.

Q: Can they be cut or modified on-site?
A: Yes, but diamond cutting tools must be used.

Q: How to choose the right adhesive?
A: Select based on the operating temperature—epoxy adhesive for room temperature and inorganic adhesive for high temperatures.

Q: What is the maximum size available?
A: The maximum single-piece size can reach 1000 × 500mm.
