In view of the torsional vibration problem main drive system F5 rolling mill in a steel plant, two sets torque monitoring sensors were installed on cross universal joint shaft site. Through online monitoring, it is found that frequency twice rotational system, and amplitude upper greater than lower shaft. Considering influence inclination angle shaft, transmission can be simplified as multi-bod...

in this article, the experiments carried out on making, rolling and measuring the physical and mechanical properties of iow - carbon ferritic steels of various phosphorus contents ranging from 0.0 11 to 0.085 percent are discussed • the results indicate that possibility of performance of both cold and hot rolling operations up to at least one fourth of the initial thickness exists through a seq...

in this study, the effects of nitrogen addition on the production of ultrafine/nano grained aisi 201l stainlesssteel by advanced thermo-mechanical process were investigated. cast samples were first homogenized at 1200 °c for 4 h, hot-rolled at 1100 °c and finally, solution-annealed at 1150 °c for 2.5 h. unidirectional and cross multipass cold rolling at 25 °c was carried out to 90% reduction in...

Abstract Intermediate roll shifting (IRS) is widely used for improving the strip shape in six-high tandem cold mill, but most related studies are limited to a single stand. To fill knowledge gap, three-dimensional (3D) multi-stand elastic–plastic finite element (FE) model was developed continuously variable crown (CVC)-6 mill using data transfer, which then validated by industrial experimental ...
