METHOD OF IMPROVEMENT FOR A ROLLED PRODUCT MANUFACTURING PROCESS

摘要

A method for controlling the rolling process of a rolled product, such as a steel, aluminium or plastic product. Controlling the rolling process refers to the minimization of the periodic machine-direction gauge variation of a rolled product and/or the minimization of roll force fluctuation and/or the control of surface roughness and/or the reduction of vibration and/or the extension of a service life for a rolling apparatus and/or the control of thermal expansion. Rolls, such as backing rolls, are provided with a run-out by machining a desired shape in the roll shell and/or roll neck and/or bearing components, such as a bearing bush. Said desired shape is non-circular and/or it is established by varying the bush thickness and/or a desired path is provided for the centre of rotation of a workpiece.
