Industrial warm forging of steel is carried
out at temperatures ranging from 650 to 950 degrees centigrade.
Conventional state-of-the-art methods have involved the application
of graphite mineral oil-based die lubricants. However, a high amount
of waste is produced through the use of these materials, resulting
in very high disposal costs and an unpleasant working environment.
The aim of this project was to develop of environmentally
acceptable lubricating systems for warm forging. The partners developed
mineral oil-free slug coatings and die lubricants displaying excellent
lubricating properties which can be used over the complete warm
forging temperature range.
The new products have been shown to increase
tool life by 30 to 50 % under industrial conditions. Further tests
concerning chemical and toxicological properties and environmental
effects with respect to emissions, waste water and other waste products
all confirm the superiority of the new lubricants.
Partners have already launched new products
on the market and at least one end user has attributed an important
increase in turnover and employment to the results of this Brite
