The present invention relates to a device for continuous or semi-continuous casting of a metal material. The device comprises a first arrangement comprising a coil () having an extension around the casting mould () in an area, which is arranged to comprise molten metal material. The coil () is arranged to be fed with alternating current such that a varying magnetic field generated and is applied to the molten metal material in the casting mould (). The device also comprises a second arrangement comprising at least two magnetic poles (), which are provided at opposite sides of the casting mould (). The poles () are arranged to supply a static or periodic low-frequency magnetic field to the molten metal material in the casting area. The poles () comprise at least a portion () which comprises a plurality of material layers which are electrically insulated from each other.

Device for continuous or semi-continuous casting of metal material

A device for continuous or semi-continuous casting of metal comprising a mould having a number of mould elements () which together form a mould adapted for receiving a liquid metal (), a mould supporting structure () surrounding the mould and mechanically supporting it, and an induction coil () arranged close to the mould for reducing the contact pressure between the melt and the mould. At least one of the mould elements is divided into at least a first () and a second () part arranged so that they are electrically insulated from each other, the first mould element part being arranged before the second mould element part relative to the casting direction and said induction coil is arranged close to the first mould element part ().
