Objective
The development of new high strength steels (TRIP, Dual Phase etc¿) on cold mills significantly increases strip guiding troubles and related effects (degraded strip flatness, roll changes ¿).
This project first aims at developing mathematical models accounting for physical phenomena involved in these strip-guiding troubles. In a second time, these models associated with rolling trials will be derived in practical recommendations to improve cold mill productivity and product quality.
The related benefits would be:
- to facilitate the development of high strength steels by the possibility to achieve higher reductions without guiding troubles or flatness degrading effects.
- to advise equipment purchases required for strip guiding control on continuous tandem mills.
