The CD process is a primary requirement for rolling mills work roll application. This process consists of electrolytic deposition of a metallic chrome layer which has specific and unique properties.
This layer has a micro-cracked structure providing low stress, high lubricity, low coefficient of friction and high reproducibility of the substrate roughness. High density micro-cracks act as lubricant reservoirs and effectively reduce the strip/roll contact area.
Benefits of chrome plating to cold mills :
- Increase rolls life
- Reduced stock removal
- Increase resistance to rolls damage
- Improve strip flatness and cleanness
- Improve mill reduction (energy savings)
- Reduce mills downtime
- Increase choice of rolls manufacturer and variety of inventory
