Sleeve for Sink Roll, Stabilizer Roll, and Correcting Roll in CGL Lines
General Description
In Continuous Galvanizing Lines (CGL), rolls such as Sink Rolls, Stabilizer Rolls, and Correcting Rolls operate under extreme heat and corrosion conditions in molten zinc or aluminum baths. The sleeve is a critical component placed between the roll shaft and outer shell to protect against wear, thermal stress, and chemical attack. It ensures stable rotation and extends the lifespan of key roll components in high-temperature galvanizing environments.
Key Features
High-Temperature Alloy Composition:
Manufactured using cobalt- or nickel-based heat-resistant alloys for superior performance above 1000°C.
Precision Casting Process:
Produced using centrifugal or investment casting methods for uniform structure and dimensional stability.
Exceptional Wear Resistance:
Withstands high rotational loads and abrasive environments over long service periods.
Thermal Compatibility:
Engineered to accommodate thermal expansion, minimizing
the risk of slippage or deformation during operation.
Custom Design:
All aspects including dimensions, key slot geometry,
and material composition are adjustable based on customer requirements.
Benefits & Performance
Significantly reduces wear on roll shafts, increasing equipment life.
Maintains consistent performance under high thermal and mechanical stress.
Excellent resistance to corrosion from molten zinc and aluminum.
Helps reduce maintenance frequency and unexpected downtime.
Contributes to more efficient and reliable continuous galvanizing operations.
Function
The sleeve serves as a wear-resistant interface between the roll shaft and the outer roll shell, providing thermal and mechanical protection in high-temperature galvanizing environments.
