Cold Rolling Mill Machine Of The Transimit Side Work Roller Bearing Block
The functional role of the working roll bearing seat on the transmission side of the cold rolling mill
Support the work roll to withstand radial and axial forces during the rolling process.
Ensure precise positioning of the work rolls and maintain the thickness and surface quality of the rolled sheet.
Adapt to harsh working conditions such as high speed, heavy load, and high temperature (due to heat generated by rolling friction).
Typical applications
Precision rolling production lines for cold-rolled strip steel, stainless steel, aluminum foil, etc.
Continuous rolling mill (such as acid rolling combined unit), reversible rolling mill and other equipment.
Material selection for the bearing seat of the working roll on the transmission side of the cold rolling mill
Common materials
Cast iron:
HT250/HT300 (gray cast iron): Low cost, good pressure resistance, suitable for small and medium loads.
QT400-18/QT500-7 (ductile iron): It combines strength and toughness, with better fatigue resistance.
Cast steel:
ZG270-500/ZG310-570 (carbon steel castings): High load-bearing capacity, used for heavy-duty rolling mills.
Alloy cast steel (such as ZG35CrMo): Adding elements such as Cr and Mo to enhance wear resistance and high-temperature strength.
Forged steel:
42CrMo/34CrNiMo6: Higher strength obtained through forging process, used for high-end rolling mills.
Selection criteria
Load size (rolling force, impact force).
Wear resistance requirements (friction with the bearing mating surface).
Thermal deformation resistance (local temperature rise during rolling process).
Key processes:
Coaxiality (≤ 0.02mm) and cylindricity control of bearing holes.
The mating surface needs to be ground or scraped to ensure contact accuracy.
heat treatment
Annealing/normalizing: eliminating casting/forging stress.
Quenching and tempering treatment (quenching+high-temperature tempering): improves the comprehensive mechanical properties (such as the hardness HRC28-32 of 42CrMo after quenching and tempering).
Surface hardening (optional): Perform high-frequency quenching or carburizing treatment on the bearing mating surface.
