Patent ID: 7305271

Claim:
A computer program product for controlling an apparatus for continuous casting of metals, the computer program product comprising: a computer readable medium; and computer program instructions recorded on the computer readable medium executable by a processor for performing the steps of supplying current to windings operative to generate at least one magnetic field to exert an influence on a movement of molten metal, wherein the at least one magnetic field is controlled by supplying the current dependent upon a value of one or more predetermined casting parameters, wherein in generating the at least one magnetic field comprises: generating a stationary magnetic field with a variable strength across the elongated cross section of the casting mold in the vicinity of, or below, where the molten metal is supplied; and generating a variable magnetic field in an area of the upper surface of molten metal in a region that is centrally located with respect to the elongated cross section and in the vicinity of where the molten metal is supplied, wherein the stationary magnetic field and the variable magnetic field are generated independently of each other, wherein the stationary magnetic field and the variable magnetic field will have an appearance that is dependent on a value prevailing of one or more predetermined casting parameters, wherein the variable magnetic field is generated by sending electric current through electric conductor windings that surround magnetic cores, and wherein the supply of current to the windings is dependent on a value prevailing of one or more predetermined casting parameters for control of the magnetic fields.
