To improve cold rolling processes, it is necessary to understand and to optimise contact at roll–strip interface. Thus a simulation test has been developed in our laboratory. The upsetting rolling test (URT) enables to study friction and iron fines pollution by the reproduction of the main industrial contact conditions such as plastic strain, normal and tangential stresses and forward slip. On the...
A prototype testing device called upsetting rolling test (URT) was developed a few years ago and was recently optimised in our laboratory to simulate mechanical and thermal contact conditions in cold rolling. Moreover a new experimental protocol has been designed to reproduce the industrial quasi-boundary lubrication regime. Numerous experiments have been then carried out to study the influence of...
