Advanced Method to Improve Work Roll Life Time and Surface Quality of Hot Rolled Strip by New Coupled Oil Free Lubrication and Chilling

Duration: 01.07.2008 — 31.12.2011

Funding resources

Ministerstvo školství, mládeže a tělovýchovy ČR - Výzkumný program Výzkumného fondu pro uhlí a ocel

- whole funder (2008-07-01 - 2011-12-31)

On the project

CHILLUB will gain detailed knowledge on the mechanism of heat transfer in front of the roll bite, the mechanism of friction and roll fatigue in the roll bite when applying new coupled oil free lubricant (water soluble) with strip cooling (chilling) during hot rolling. The mechanisms will be related to work roll deterioration and strip surface quality. Secondary the suppressing of scale formation is examined. Objectives of the investigations are: - Increase work roll life time - Improving strip surface quality - Enlarged process window when rolling high strength steels. Results are integrated into set-up and control models revealing into an industrial prototype.
