Patent ID: 10464118

Abstract:
A method for producing a contoured ring rolling product for a rotating application from a ring blank, with a ring rolling machine controlled in a process-monitored manner. At least one process window, extending over the rolling time, is defined in relation to preselected process parameters for the specific product on the basis of calibrating specimens brought into their final form by the ring rolling machine. The process window(s) monitored during the process is/are determined by the process parameters of calibrating specimens which produced rolled products meeting the requirements demanded of the ring rolling product. The preselected process parameters comprise at least two of ring growing rate, axial rolling force, radial rolling force, rolling time, and ring blank temperature. Ring blanks are subsequently rolled in a contoured manner with parameters of the rolled blanks being recorded with reference to the preselected process parameters and evaluated to ascertain whether they lie within the predefined process window(s), thereby determining whether they are accepted for further machining and/or processing.
