Wear Plates for Rolling Mills

Rolling Mill Wear Plates & Liners: Key Protective Parts

Core Functions

• Protect the Mill Housing: The mill housing is the most valuable fixed part of the rolling mill. Bearing chocks move often during rolling. Wear plates take the wear instead of the housing, so you only need to replace the cheap wear plates instead of repairing the expensive housing.

• Guide Bearing Chocks Precisely: To make rolled steel plates of even thickness, bearing chocks must move stably. Wear plates guide them, stop horizontal swing, and keep rolls in the right position under high pressure.

• Buffer Impact Energy: When steel billets enter the rolls, they cause vibration and force. Wear plates spread this force evenly to the housing and reduce impact, preventing cracks on the housing.

• Resist Corrosion & Aid Lubrication: Rolling mills have cooling water, emulsion and scale. Wear plates form a barrier to stop scale from causing wear, and keep water away to reduce housing corrosion.

Application Scenarios

• Hot and cold rolling mill housing windows (on work roll and support roll bearing chocks)

• Pushing and guiding systems (on push heads and guide plates, to resist billet impact)

• Roll changing devices (help heavy rolls slide smoothly without damaging the stand base)

How Quality Wear Plates Improve Efficiency & Longevity

• Strong Material: Made of high-quality alloy/bimetal, with surface hardness 52-55 HRC. Resists wear and impact well, even with scale and water.

• Precise Size: Ground to tight tolerances. Keeps bearing chocks aligned, reduces vibration, and improves steel product quality.

• Less Downtime: Lasts longer, so you replace them less often. Enables planned maintenance and fewer emergency stops.

• Custom-Made: Fits your mill’s unique needs (e.g., special oil grooves). Works with major brands like SMS Group, Primetals, Danieli.
