There is increasing demand for direct-supply hot rolled coil to be to the required flatness, without crossbow or longbow, and with minimal residual stress. In practice, strip leaving the finishing mill can be measured without flatness deviations and assumed to be stress free. However, the cold...

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...

The aim of the project was the reduction of shape defects and yield losses in heavy plate rolling by providing new operating strategies, ski-end control and optimised set-up adaptation for ski and control for camber/thickness profile. This approach encompasses the application of the new...

The claim to produce flat products in hot strip rolling lines strictly tailored to the demands of next step processes and final customers has been tackled for a long time only in terms of enhanced local flatness of the strip in the line. Thus the core aim of the project is the development of a...

Nowadays the flatness performance of plate manufacturing lines is still tackled in terms of enhanced local flatness of the plates in the line. The aims of this project had been to optimise local flatness approaches and to progress from this basis by taking the flatness requirements of the...

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...
