Abstract:
1. An apparatus for continuous casting of metals, comprising: a casting mold with an elongated horizontal cross section, through which a molten metal is intended to pass during the casting process, a member for supplying a molten metal to such molten metal already present in the casting mold in a region at a distance below the upper surface of the latter melt, and a device adapted to apply magnetic fields to the melt in the casting mold to exert an influence on movements of the molten metal, wherein the device exhibits members adapted to generate a stationary magnetic field with a variable strength across essentially the whole of said cross section of the casting mold from one long side to the other long side in the vicinity of, or below, the region for said supply of the molten metal, members adapted to generate a variable magnetic field in the area of said upper surface in a region that is centrally located with respect to said cross section and close to said region for supply of melt, measuring members operative to measure casting parameters, and wherein the apparatus comprises a unit adapted to control the magnetic members of the device to generate, independently of each other, magnetic fields with an appearance that is dependent on the value prevailing of one or more predetermined casting parameters, wherein said magnetic members comprise magnetic cores and electric conductor windings passed around these, wherein the apparatus comprises one or more sources for supplying electric current to these windings, and wherein said unit is adapted to control the supply of current to the windings in dependence on the value prevailing of one or more predetermined casting parameters.
