摘要： Molten metal, or other electrically conductive material, in a vessel can be inductively heated, and simultaneously inductively stirred. A single-phase ac supply provides induction heating power to at least one set of three induction coil sections surrounding the vessel. A three-phase ac supply provides induction stirring power to at least one set of three induction coil sections surrounding the vessel. The single-phase ac supply is capacitively connected to the coil sections to form a heat resonance circuit, and the three-phase ac supply is inductively connected to the coil sections to form a stir resonance circuit. The heat circuit capacitive elements provide a sufficient impedance to the output of the three-phase ac supply to block power transfer from its output to the input of the single-phase supply. The stir circuit inductive elements provide a sufficient impedance to the output of the single-phase supply to block power transfer from its output to the input of the three-phase supply.

摘要： It is an object of the present invention to prevent oxidation during the metal melting, by suspending both heating and supply of metal material under the monitoring by measuring the oxygen concentration in the inactive gas atmosphere. A oxidation prevent method of melting metal material by a melting vessel 1 comprising inside a rotatable agitation member 8, having a weighing chamber 4 communicating with a nozzle member 2, and an injection member 9 advanceably and retractably inserting an extremity injection plunger 12 passing through the agitation member 8 in the weighing chamber 4, and the melting vessel being installed on a slant with the nozzle member 2 downside. The space area over the melted metal surface 15a of the melting vessel 1 is made into inactive gas atmosphere. The oxygen concentration in this space area is measured and monitored. It is judged as error when the measured oxygen concentration exceeds a predetermined reference value, and heating and material supply are suspended to prevent the melt metal from oxidizing.

摘要： An electric arc furnace (1), wherein solids are injected into the furnace chamber. The lances (9, 10, 11) are guided through the wall (12) of the electric arc furnace (1) and inserted into the wall of the furnace, whereby at least one lance is associated with each electrode (2, 3, 4), in order to enable a homogenous formation of slag and to inject as great an amount of solids as possible. The lances are distributed in an approximately uniform manner along the periphery of the furnace. The inclination of the lances and thus the angle of injection are selected in such a way that they form an angle of approximately 30-80° in relation to the flow direction of the melting bath and form an angle of approximately 10-30° in relation to the horizontal.
