QUALITY SURFACE ENGINEERING & GLOBAL PROCESSING SERVICES
High quality roll surface is achieved by using high precision CNC grinders, on line roll surface measurement, cracks and bruise detection with NDT equipment (Eddy current, ultra sound & surface wave).
We provide :
High quality level and homogeneous roll surface,
Improved roll profile, within a range of 2 microns
Stock removal reduced to the optimum
We provide work roll body, journal repair and keyway repairing.
Electro-Discharge Texturing provides high quality textured surface in a range of 1,5 to 10mm Improved roll roughness consistency is achieved through high level process control of the EDT machine variables.
Benefits of EDT compared to shot blasting (SBT):
Ra variation within a range of +/-5%
High peak count (Pc)
Lower waviness (Wa)
Improved strip control
We provide chock maintenance program, including full inspection and repairing.
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
