Rolloilfree – Steel cold rolling with aqueous oilfree lubricants

Situation:

  • Oil-based lubricants are state-of-the-art in cold rolling of steel and hot rolling of aluminium. 2-phase character of emulsions and associated property profile requires condition monitoring to avoid process instabilities.
  • Increased effort and expenditure for care, control and losses compensation of lubricants.
  • High safety and environmental standards for conventional lubricants.
  • High expenses for recycling, therefore transfer to thermal recycling (down-cycling).

Solution:

  • Targeted development of oil-free lubricants by application of the tribological test chain
  • Consideration of environmental aspects with respect to application, safety, care and recovery of aqueous oil-free lubricants.
  • Testing and evaluation of an industrial implementation.

Operational benefit:

  • Use of oil-free lubricants with the same or improved property profile
  • Simplification of lubricant maintenance and control  efforts (improved handling)
  • Improvement of strip surface quality due to reduced surface contamination
  • Relief of the following processes
  • Reduction of operating, maintenance and recycling costs
  • Saving of environmental resources
  • Simplifying compliance with safety and environmental standards
