摘要： A ladle or tundish has a side wall comprising a refractory lining adapted to be contacted by molten metal, and a concrete wall surrounding the lining and reinforced by metal wires, the side wall being free from a metal shell. Therefore the side wall is relatively permeable to the field of an induction heating coil on the outside of the side wall.

摘要： A direct induction furnace or device for melting a charge held in a cold sheath or shroud with electromagnetic confinement of the conducting portions of the charge. The cold shroud comprises a cylindrical sidewall, which is composed of a plurality of juxtaposed segments in the shape of a hairpin inductor, each formed by two parallel tubular conductors, which are insulated from each other along their entire interface with the exception of a transverse section which electrically and hydraulically connects one end of one of the sections to the adjacent end of the other section.The other ends of these two conductors are, respectively, electrically and hydraulically connected by tubular conductors to two tubular ring-shaped collectors which are respectively electrically connected to two output terminals of a second generator of alternating current of medium or high frequency, in such a way that the alternating currents which thus flow through the cluster of tubular conductors making up the cold shroud, flow alternately in opposite directions so as to generate forces of repulsion at the periphery of the conducting portion of the charge, which is thus kept away from the shroud sidewall, thereby ensuring a supplementary confinement thereof.

摘要： This invention relates to melting and refining apparatus and processes, and is concerned with the problem of obtaining the correct metallurgical conditions in coreless induction furnaces. The invention consists in using a furnace with a single work coil connected through switching means to one or more electric power sources arranged so that the frequency applied to the single work coil can be varied. The electric power may be supplied by a single variable frequency power source such as a static thyristor inverter device, or by a number of individual sources, each designed to produce electric currents alternating at a particular frequency. This arrangement enables material to be melted by supplying current to the work coil at high power and a high frequency and to be refined by using a low power and a low frequency.

摘要： A cold crucible induction melting furnace is provided with a plurality of segments separated by a plurality of slits that surround a bottom member which together form the melting chamber. Each lower end of each segment is overlapped with and spaced from a short part of a vertically extending side wall of the bottom member so as to form a horizontal gap there between. A radially and outwardly extending flange protrudes from the bottom member side wall below each segment lower end to form a lower gap there between. An induction coil is disposed around and spaced from an outer face of the segments with a lower end adjacent to each of the lower segment ends and an upper end adjacent to an upper part of each segment that is in turn connected with an adjacent upper segment part to form a short circuited part. The radial thickness of each segment from the upper end of the coil to the lower end of the segments is the same and the magnetic flux generated by the induction coil passing through the lower gap and the horizontal gap provides increased magnetic flux density at least adjacent to the region adjacent to the bottom member and the lower ends of the segments.

摘要： A device is provided for melting by direct induction substances which are dielectric when cold and whose temperatures of inductibility and melting are close to each other, such as glasses or vitreous enamels. This melting is carried out inside a receptacle whose sidewall comprises a multi-turn inductor made from metal tubing whose inward-looking faces are exposed and which combines the functions of heating the charge by induction and cooling the periphery thereof. Such a receptacle which is at the same time a heating inductor and a cooling surface is applicable more especially to industrial electric furnaces for the production of molten glass or enamel by direct induction.

摘要： An induction crucible furnace includes a housing having a bottom wall and side walls which define a furnace cage. A prefabricated refractory crucible made of a mixture of a dry ramming material, a sintering agent and a cold-curing binder is disposed within the furnace cage with a clearance which is filled with a non-sintering granular material sealed within the furnace with a patching compound. A plurality of induction coils are disposed within the furnace cage and are separated from a layer of the non-sintering granular material by a heat-protective layer. In a method of manufacturing of the induction crucible furnace a refractory crucible is placed onto a bed of a non-sintering granular material disposed on the bottom wall of the furnace housing. A non-sintering granular material is filled into an annular space between the furnace cage and the crucible, then this material is compacted, closed and the furance is started up to reach the temperatures causing sintering of the mixture of the prefabricated refractory crucible.
