Variable mechanical and physical properties arise in final cold coil from hot flat mills, that can degrade the performance of the product. A multi-national project, involving Arcelor Research SA, MEFOS and Corus UK, has been carried out to address this issue, by improving consistency via better...

The work in this project has involved work on the most important models in the plate rolling mills. The following subjects have been studied : - plate temperature model, - roll force model, - roll thermal expansion, - top-view plate shape, - plate warping and bending. Aceralia has worked with...

Modelling of some aspects of defect formation through different passes in a hot strip mill was conducted, but further work required characterisation of friction in the roll gap. Hot plane strain compression testing gave mean friction results of limited applicability. Tests using an experimental...

ln order to achieve an enhanced shape and thickness profile and reduce camber and ski during plate rolling, detailed area information about varying geometric features along and across the plate had to be measured and exploited by advanced command and control strategies, which had to be derived...

ln order to satisfy downstream and customer requirements referring to strip quality features such as thickness profile, camber, width and flatness, all influences on strip quality, such as inter-stand tension, strip tracking, roll bending and roll shifting, strip cooling and strip coiling, have...

This research project had the aim to demonstrate the proper operation of the advanced edge-masking technologies in the Hot Strip Mills (HSM) to improve flatness in strip edges. In order to control the lower temperature in the edges of the strip in the Run-out Table (ROT), edge masking devices...
