Abstract:
The back-up rolls of hot strip mills wear considerably under the conditions of high temperature and heavy load, which affects the roll service period and the stability of strip profile control. Serious uneven wear, short service periods, and spalling problems occurred on conventional back-up rolls of upstream stand CVC mills in 1500 mm continuous hot rolling production lines. Through finite element simulations, the problems are determined to be caused by the configuration of a flat roll contour of the back-up roll and the CVC roll contour of the work roll, which leads to uneven contact pressur

Abstract:
Rolling mills vibration is a key factor that hinders the production of thin-strip steel. Currently, vibration is mainly suppressed by adjusting rolling mill parameters which is not a common approach. Due to special working conditions, the information of work roll, such as displacement and velocity, cannot be directly measured. Therefore, based on extended state observer, new resonance ratio control method, which is a common approach, is proposed to suppress the rolling mill vibration. First, the equivalent mass of the back roll is identified. Then, the interaction force between the work roll a

Abstract:
The twisting of an erect round metal roller (beam, roll) has a place in many metallurgical processes. For example, in the rolls of a wide-band mill at rolling of metal slab, in the leading rolls of flattening machines, in the asymmetric three-roll machines at bending of metal sheet, and so on. Under the large external torques in an erect metal roll, the plastic deformations can occur, which lead to the large residual stresses after an unloading of round roll. These residual stresses can bend the axis of the roll or cause it to a collapse under the subsequent loads. To estimate the value of res

Abstract Three-point roll bending is one of the most common forming processes employed to obtain the desired radius of curvature in the sheet metal operations.
