A rapid calculation method for predicting roll deformation of
The method to predict roll deformation precisely and efficiently is vital for the strip shape control of a six-high rolling mill. Traditional calculation methods of roll deformation, such as the finite element method and the influence function method, have been widely used due to their accuracies. However, the required calculation time is too There is disclosed a method and apparatus to determine the proper unloaded screwdown setting for at least one stand of a rolling mill prior to a work strip entering that mill stand and in relation to the predicted flattening of the work rolls that will occur, when the required total roll-separating force is applied to that mill stand to obtain the desired delivery thickness ROLLING MILL STAND SCREWDOWN POSITION CONTROL

Full article: An investigation on the roll force and torque
3.1. Roll force and torque variations during the process. In this study, the experimental rolling programs of Hum, Colquhoun, and Lenard (Citation 1996) are used to investigate the rolling force and torque changes during HSR of commercial pure aluminum.Typical contact pressure distribution in the roll gap is given in Figure 1, in which an AA1100 strip with We use the concept of the limit inclination angle of the generatrix of the roll to the rolling axis, α G, at which the conditions for axial gripping of the billet cease to be satisfied, i.e., the resulting axial force acting on the considered section of the roll is F = 0.. At α < α G, the resulting axial force is F > 0 and acts in the rolling direction (pulling force).Modernization of Helical Rolling Technology in a Multi-Roll Mill

Vibration monitoring and analysis of strip rolling mill based
A vibration monitoring method of strip rolling mill based on the digital twin model was proposed which could effectively reduce the structure complexity and test cost of the traditional monitoring system. Firstly, the coupling vibration mechanism model of the dynamic characteristics of roll system and bearings of four-high mill was established. Given the complexity of the operating conditions of rolling bearings in the actual rolling process of a hot mill and the difficulty in collecting data pertinent to fault bearings comprehensively, this paper Sensors Free Full-Text Bearing Fault Diagnosis
