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.

摘要： A method for melting steel in an electric arc furnace (EAF). A hot heel is provided in the EAF. Metal scrap is loaded into the EAF. The metal scrap is melted in the EAF. The mass of the hot heel in relation to the mass of the metal scrap that is initially beyond the surface of the hot heel is a certain minimum. This minimum is 0.75 times the relation between the heat required to melt the metal scrap beyond the surface of the hot heel and the heat that can be taken from the hot heel without it being solidified when a theoretical heat balance calculation is applied as defined in a formula.

摘要： An arrangement for a continuous casting process. The arrangement includes a vessel having a first opening for receiving molten metal in the vessel, a second opening for discharging the molten metal from the vessel, and a body extending between the first opening and the second opening, a first magnetic arrangement attached to the body, the first magnetic arrangement having a magnetic core with legs, and coils arranged around the legs, and a power system configured to provide an alternating current superimposed on a carrier current to each of the coils, each pair of alternating current and carrier current provided to a coil forming a flow control current, wherein flow control currents provided to adjacent coils are phase shifted relative each other, thereby creating a travelling magnetic field in molten metal in the vessel. A corresponding method is also presented herein.
