A device and method for prediction and/or control of the profile and/or shape of rolled metal strip. The device and method are compatible with both cluster-type and non cluster-type mills. The device and method employ a customized deflection model of the rolling mill, thereby combining the advantages of well-known finite element method with other relevant methods to allow real-time operation of the rolling mill without the computational complexities of such methods. In one form, the customized deflection model helps to obtain a compact, linear, and flexible analytical model with non-iterative solution, multiple continuous elastic foundations, third-order displacement fields, simple stress-field determination, and capability to compute dynamic deflection characteristics.
An article of manufacture comprising a computer usable medium having computer readable program code embodied therein for determining at least one of a profile value and a flatness value of a metal strip, wherein said metal strip exists in a first state prior to passage through a rolling mill and a second state after passage through said rolling mill such that said second state is possessive of at least one surface dimension different than that of said first state, said code configured such that displacement values of said metal strip and at least one component of said rolling mill corresponding to said at least one of a profile value and a flatness value associated with said second state are generated based on input parameters that identify a relationship between said rolling mill and said metal strip, said code further configured such that said rolling mill and said metal strip are modeled as a combination of a plurality of beam elements and a plurality of continuous elastic foundations coupled between said plurality of beam elements.
