Method for reproducibly producing a contoured ring rolling product for a rotating application, with a ring rolling machine controlled in a process-monitored manner, in particular from a metal ring blank of such a nature that it is susceptible to cracking, comprising the steps: - defining at least one process window, extending over the rolling time, in relation to preselected process parameters for a specific ring rolling product that is to be brought into its final form by this ring rolling machine on the basis of calibrating specimens that have been brought into their final form by this ring rolling machine, wherein the process window or windows of process parameters monitored when carrying out the process is/are determined by the process parameters of those calibrating specimens of which the rolled product meets the requirements demanded of the ring rolling product to be produced, wherein the preselected process parameters comprise at least two of the following process parameters: - ring growing rate, - axial rolling force, - radial rolling force, - rolling time - temperature of the ring blank during the rolling process, and subsequently - ring rolling of ring blanks in a contoured manner to produce the ring rolling products, wherein the rolling parameters of the rolled blank at the time are recorded with reference to the at least two selected process parameters and then evaluated to ascertain whether these process parameters lie within the predefined process window, and only those ring rolling products that have been ring-rolled with process parameters that lie within the process window are passed on for further machining and/or processing. - defining at least one process window, extending over the rolling time, in relation to preselected process parameters for a specific ring rolling product that is to be brought into its final form by this ring rolling machine on the basis of calibrating specimens that have been brought into their final form by this ring rolling machine, wherein the process window or windows of process parameters monitored when carrying out the process is/are determined by the process parameters of those calibrating specimens of which the rolled product meets the requirements demanded of the ring rolling product to be produced, wherein the preselected process parameters comprise at least two of the following process parameters: - ring growing rate, - axial rolling force, - radial rolling force, - rolling time - temperature of the ring blank during the rolling process, and subsequently - ring rolling of ring blanks in a contoured manner to produce the ring rolling products, wherein the rolling parameters of the rolled blank at the time are recorded with reference to the at least two selected process parameters and then evaluated to ascertain whether these process parameters lie within the predefined process window, and only those ring rolling products that have been ring-rolled with process parameters that lie within the process window are passed on for further machining and/or processing. - ring growing rate, - axial rolling force, - radial rolling force, - rolling time - temperature of the ring blank during the rolling process, and subsequently - ring rolling of ring blanks in a contoured manner to produce the ring rolling products, wherein the rolling parameters of the rolled blank at the time are recorded with reference to the at least two selected process parameters and then evaluated to ascertain whether these process parameters lie within the predefined process window, and only those ring rolling products that have been ring-rolled with process parameters that lie within the process window are passed on for further machining and/or processing.
