  • Patent number: 6474404
    Abstract: The invention relates to a method for controlling the temperature of a melt (10), preferably of a steel melt, in a distributing vessel (11), whereby the temperature of the melt is measured, the measured result is compared with a predetermined temperature range in the form of specified values, and as much heat is supplied or withdrawn from the melt such that the temperature remains inside said range. In order to control the melt temperature, a fireproof shaped part (20) which is closed on both sides and which is provided for accommodating a liquid cooled induction coil (1) is immersed in the melt (10). The transmission of heat is carried out by means of thermal conduction out of the wall of the shaped part (20) which is coupled to the induced electromagnetic field and/or by means of a direct coupling to the liquid melt (10).

  • Patent number: 6279915
    Abstract: A tubular refractory channel (2) that can be inserted as a flowthrough for liquid metal into a thermally insulating outer lining (10) and can be connected with the outer lining (10) by a refractory mortar layer (9). In order to prevent liquid metal from penetrating into the mortar layer (9), even if the mortar layer contracts, the outer lining (10) overlaps the metal inflow-side of a front face (4) of the channel (2).

  • Patent number: 6226314
    Abstract: An assembly includes a tapping device for flow therethrough of molten material and a cooled inductor to be connected to an electrical source and mounted with respect to the tapping device to be inductively coupled to one of the tapping device and the molten material flowing therethrough. The inductor includes an electrically conductive induction coil having therethrough at least one cooling passage. Each cooling passage has connected thereto at least one supply line for supply thereto of cooling fluid and at least one discharge line for discharge therefrom of the cooling fluids.

  • Patent number: 6217825
    Abstract: In a process for splashing and/or teeming liquid metal, in particular steel, through a discharge in the wall or in the bottom of a metallurgical vessel, the discharge is electromagnetically coupled to the electromagnetic field of at least one fluid-cooled, in particular air-cooled, inductor. The inductor and the discharge are at least partially disposed in the wall or in the bottom of the metallurgical vessel. For teeming, the electromagnetic field of the inductor, or of the inductors, is coupled directly to the discharge and also the liquid metal. For this purpose, the frequency of the electromagnetic field or the electromagnetic fields, if appropriate, is adjusted correspondingly.

  • Patent number: 6210629
    Abstract: The invention pertains to a process and an apparatus for the discontinuous tapping of melts. An inductor surrounds a passage through which the melt is discharged from a vessel. The inductor applies radial electromagnetic energy to the passage to maintain the melt in a molten state. To stop flow of the melt through the passage, an outlet opening of the passage is closed and the inductor is electrically switched off while a cooling medium is flowed through the inductor. To begin flow of the melt, the outlet opening of the passage is opened and the inductor is electrically switched on.
