High-fidelity flatness defects in cold-rolled strip and sheet, arising from highly localized thickness strain variations, present an ongoing challenge to the metal industry. A primary cause of such defects, based on rolling practice, but for which effects have not been rigorously investigated, is transfer work-roll diameter deviations due roll grinding error. This study addresses high-fidelity ...

It has great significance to research the dynamical reliability probability of rolling mill rolls system for improving its stochastic dynamical reliability and products quality rolled. The fifth-octave vertical vibration stochastic dynamical model of rolls system was established, and the pseudo-excitation method was used to obtain the power spectral density and the variance variation characteri...

The crystallographic texture of Ti–29Nb–9Ta–10Zr alloy is studied after cold-rolling with different amounts of thickness reduction, up to 60%. The major texture components developed during cold-rolling were: γ-fibre components: {111}〈 〉, {111}〈 〉, {111}〈 〉 and {111}〈 〉; texture component: {112}〈 〉 and texture components: {001}〈 〉 and {010}〈001〉. Besides crystallographic texture the resulted mec...

In cold rolling of silicon steel strip, edge drop directly affects the side cutting and yield steel. To improve in process, a multi-stand coordinated control strategy model based on multi-objective optimization are proposed. The first step is to analyze influence each stand work roll shifting (WRS) through finite element (FEM), then determine effectiveness actuator. Meanwhile, fitting proposed ...
