Dynamic rolling simulation and stiffness of 1850 furnace coil rolling mill
The stiffness of rolling mill has an important influence on the control of plate thickness and shape and the stable operation of rolling.In order to study the stiffness of the rolling mill system and the change of rolling force during the actual rolling process of the 1850 Furnace Coil Rolling Mill,based on the finite element analysis,a thermal coupling model of the rolling process of the furnace coil rolling mill was established under the extreme rolling conditions while taking into account the influence of rolling temperature.Then,the stiffness,stress and strain of key parts during the operation of the rolling mill under the influence of multiple factors were calculated.Three sets of numerical simulation were carried out according to the maximum rolling force in the rolling schedule.The deformation of each part of the rolling mill fluctuates up and down with the change of rolling force.The real-time stiffness of the rolling mill system is calculated based on the rolling force and the total vertical deformation in the rolling process.Using the average rolling force and the average deformation,the stiffness of the rolling mill is 6078,6089 and 6077kN/mm,respectively.The results show that even though the average rolling force and total deformation in the three rolling procedures are different,the stiffness values are basically the same.
