摘要： A device for continuously manufacturing a cast strand by continuous casting of liquid metal melt wherein the flow of the liquid metal in the non-solidified portions of the strand is controlled by means of a static or periodic low-frequency magnetic field. A mould adapted to be supplied with the melt includes copper plates (2a,2b) which form a casting mould space with a rectangular cross section, water box beams (3) which are arranged outside the copper plates to support and cool them, and a member (4) holding the mould together. Magnetic field-generating devices, i.e., magnets, are provided close to the mould to generate a static or periodic low-frequency magnetic field which acts in the path of the inflowing melt and divides the primary flow as well as checks any secondary flows arising. Each magnet comprises a front core (5), a rear core and a coil (7). The front core is a fully integral part of the water box beam and the rear core comprises a rear movable part (6b) which is movable in a direction which substantially coincides with the direction of the field.

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 apparatus for crystallization of silicon includes a crucible for containing silicon, a heating and heat dissipating arrangement provided for melting the silicon contained in the crucible and for subsequently solidifying the molten silicon, and an electromagnetic stirring device provided for stirring the molten silicon in the crucible during the solidification of the molten silicon. A control arrangement is provided for controlling the heating and heat dissipating arrangement to solidify the molten silicon at a specified solidification rate and for controlling the electromagnetic stirring device to stir the molten silicon in response to the specified solidification rate of the molten silicon such that the ratio of a speed of the molten silicon and the specified solidification rate is above a first threshold value.

摘要： A method for casting of metal. A mold is provided including two broad sides and two narrow sides. A molten metal is introduced into the mold. There is a meniscus at a top of the molten metal. Additional molten metal is supplied into the molten metal via a casting tube below the meniscus. At least one stirrer including an iron core and a coil applied around the iron core is arranged around the mold. A length of the iron core in relation to a length of the broad side of the mold is between 50% and 80% of the length of the broad side. An upper part of the iron core is positioned from 50 mm above to 195 mm below the surface of the meniscus. A magnetic field is applied to the molten metal with the at least one stirrer to stir the molten metal.
