QUALITY SURFACE ENGINEERING & GLOBAL PROCESSING SERVICES

SERVICES

Grinding

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

Rolls Hospital

We provide work roll body, journal repair and keyway repairing.

EDT Texturing

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

Chocks Maintenance

We provide chock maintenance program, including full inspection and repairing.

Chrome Plating

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
