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
