摘要： A device for continuous or semi-continuous casting of metal comprising a cooled mold (22) and an induction coil (10) arranged at the top end of the mold. The mold comprises in its top end a plurality of hollow, old segments (22a, 22b, 22c, 22d, 22e, 22f, 22′b, 22′c, 22′d) separated from each other by partitions (26a, 26b, 26c, 26d, 26e), which all comprise an electrically insulating barrier. Both the mold segments and the partitions are oriented essentially in the casting direction. Each hollow top end mold segment comprises a core of a mechanically supporting bar or beam (25a, 25b, 25c, 25d, 25e, 25f, 25′a, 25′b, 25′c, 25′d, 25′e, 25′f) arranged within the hollow mold segment such that it is surrounded by the hollow mold segment. The core exhibits superior mechanical properties in relation to the mold.

摘要： A device for continuous or semi-continuous casting of metal has a cooled continuous casting mold assembly and an inductive coil arranged at the top end of the mold assembly. The mold assembly is divided into at least two mold assembly parts separated and electrically insulated from each other by partitions, which are oriented in the casting direction and where each partition is formed with an electrically insulating barrier. Each mold assembly part has a mold part associated with a corresponding mechanically supporting mold back-up structure part, and an electrical conductor, with an electrical conductivity higher than the electrical conductivity of the back-up structure. The conductor is arranged with the mold back-up structure part on the side of the mold back-up structure part facing away from the mold, the outside face.

摘要： A method for reducing vortex formation in molten metal when bottom tapping the molten metal from a metallurgical vessel in a metal making process. The method includes the steps of tapping the molten metal via a tapping hole in the metallurgical vessel, and providing a flow of the molten metal in the metallurgical vessel while tapping via a time-varying electromagnetic field applied to the metallurgical vessel, the flow of the molten metal being such that it constantly moves vortices in the molten metal away from a tapping hole region during the tapping to thereby prevent accumulation of the vortices for vortex formation over the tapping hole. It is also presented an arrangement for carrying out the method.
