Calculation Model for Thermal Crown of Work Roll in Hot Strip Rolling

Abstract:

The finite difference method model of temperature field and thermal crown of work roll on hot strip mill was researched. The temperature field and thermal crown were calculated, surface temperature distribution and thermal deformation were both reduced from center to edge. The computed and measured roll surface temperature were comparatively in good agreement with each other, practical application results show that the model has high calculating speed, high precision and can meet the needs of the strip shape on-line process control.
