摘要： An induction heating system can comprise a furnace chamber comprising a non-magnetic and non-conductive furnace wall; at least one induction heating coil surrounding an outer side of the furnace wall in a length direction (z) of the furnace chamber; and a holding and pressing construction. The holding and pressing construction can be designed to hold an arrangement to be placed within the furnace chamber, and the holding and pressing construction can apply a pressure on a proximal end and a distal end of the arrangement in the length direction of the chamber.

摘要： The present invention relates to an arrangement for low-pressure casting of refractory metals, with a furnace chamber with one or a plurality of gas supply openings (6) and gas outlet openings (7), and a riser pipe (8) through a cover (5) of the furnace chamber, a melting container (3, 12) for the refractory metals arranged in the furnace chamber, and a heating device for heating the refractory metals in the melting container (3, 12). In the proposed arrangement, the melting container (3, 12) is formed as an exchangeable insert for a receiving mould (2) supporting the melting container (3, 12), which is arranged in the furnace chamber, wherein a thermally insulating layer (4, 17) is formed between the receiving mould (2) and the melting container (3, 12), or is integrated into the melting container (3, 12). With the proposed arrangement, a quick and easy exchange of the melting container for different alloys can also be carried out in the low-pressure casting of refractory metals.

摘要： A method for the recrystallisation annealing of a non-grain-oriented electric strip (2) in a continuous annealing and coating line (1) is presented. Therein, the electric strip (2) is heated in an induction furnace (5) to a temperature of at least 680° C. at a heating rate of at least 80 K/s and then, in an optional second continuous furnace (8), to a temperature of at least 820° C. at a heating rate of at most 20 K/s. The electric strip (2) is initially heated before the induction furnace (5) via a first continuous furnace (3) to a temperature of at least 300° C. at a heating rate of at most 60 K/s.

摘要： The transverse flux induction heating device is allows an alternating magnetic field to intersect the sheet face of a conductive sheet which is conveyed in one direction, thereby inductively heating the conductive sheet. The transverse flux induction heating device includes a heating coil disposed such that a coil face faces the sheet face of the conductive sheet; a core around which the heating coil is coiled; a shielding plate formed of a conductor and disposed between the core and a side end portion in the direction perpendicular to a conveyance direction of the conductive sheet; and a non-conductive 10 soft magnetic material which is attached to the shielding plate, wherein the shielding plate is interposed between the core and the non-conductive soft magnetic material.

摘要： A metallurgical system for producing metals and metal alloys includes a fluid cooled mixing cold hearth having a melting cavity configured to hold a raw material for melting into a molten metal, and a mechanical drive configured to mount and move the mixing cold hearth for mixing the raw material. The system also includes a heat source configured to heat the raw material in the melting cavity, and a heat removal system configured to provide adjustable insulation for the molten metal. The mixing cold hearth can be configured as a removal element of an assembly of interchangeable mixing cold hearths, with each mixing cold hearth of the assembly configured for melting a specific category of raw materials. A process includes the steps of providing the mixing cold hearth, feeding the raw material into the melting cavity, heating the raw material, and moving the mixing cold hearth during the heating step.
