Patent ID: 8718985

Claim:
A method for establishing machine code which can be executed directly by a computer to implement a rolling model for a rolling process of a rolling stock by a rolling mill train having at least one rolling stand, the method comprising: establishing or accessing a basic model based on a plurality of known mathematical functions that are not specifically adapted to the particular rolling process, for each of a plurality of different rolling stock conditions within a range of rolling stock conditions and a plurality of different rolling stand settings within a range of rolling stand settings: predefining a respective rolling stock condition and a respective rolling stand setting for the basic model, and using the basic model to determine an output condition corresponding to the respective rolling stock condition and the respective basic rolling stand setting using the basic model, wherein the output condition is defined by a number of weighting factors which each specify the extent to which a respective corresponding mathematical function of the plurality of known mathematical functions occurs in the rolling stock following the rolling process defined by the respective rolling stock condition and the respective rolling stand setting, analyzing all of the output conditions corresponding to the plurality of different rolling stock conditions and plurality of different rolling stand settings, determining adapted mathematical functions based on the analysis of all of the output conditions, wherein the number of adapted mathematical functions is significantly smaller than the number of the plurality of known mathematical functions of the basic model, establishing the rolling model using the adapted mathematical functions, and establishing the machine code based on the rolling model.
