摘要： The present invention relates to a method as well as to an induction furnace for continuously melting a metallic or metal-containing bulk material in the shape of small pieces. The metallic bulk material is supplied from the top onto the melt located in the vessel of the furnace. An stirring movement is applied to the melt located in the upper area using an alternating field produced by a first magnetic coil (induction coil 11) which is arranged around the furnace vessel. Heat is simultaneously supplied to the melt, used as a short-circuited secondary winding, in the lower region of the induction-furnace crucible (13) about the iron core (16) of a low-frequency transformer.

摘要： An induction heating furnace (10) comprises an induction coil assembly (16) and a ladle (12) having a metallic shell (14) that supports a crucible holding metal to be heated by the furnace. The ladle (12) is readily separated from the induction coil assembly (16) so that the heated metal may be conveniently and reliably moved among operational stations. The induction coil assembly (16) has a preselected length which is less than the length of the shell (14). The induction coil assembly (16) surrounds, but does not touch, the shell (14) and generates an electromagnetic induction field. The induction coil assembly (16) comprises a coil (20), upper and lower yokes (28 and 34) and an intermediate yoke (40) coextensive with the coil (20). The upper and lower yokes (28 and 34) are separated from each other and electromagnetically coupled together by the intermediate yoke (40). The upper, lower and intermediate yokes (28,34 and 40) preferably each comprise stacked laminates (72 and 74) formed of sheets of ferrous material.

摘要： A high frequency core and coil electric metal melting furnace is shown. This furnace has a channel (14, 16, 18) in its inductor for carrying the molten metal. The invention provides a lining (26) of the channel (14, 16, 18) such that the furnace is not subject to leakage of the molten metal from the channel into the rammed refractory support bed (24) for the channel which leakage otherwise shortens the life of the furnace. Also a method of lining the channel in the inductor for carrying the molten metal which forms the core is disclosed.

摘要： An improved refractory inductor block (20) is provided for channel induction furnaces (2) for melting aluminium comprising a hearth (6) and an inductor (10). The improvement comprises casting the refractory inductor block (20) from a refractory resistant to corrosion by molten aluminium comprising 9.5 to 40 wt.% calcium aluminate, 0.5 to 10 wt.% of a borosilicate frit, and 60 to 90 wt.% of an aggregate consisting of an alumina-bearing compound, a silica-bearing compound or mixtures thereof. The refractory is cast around a solid core pattern (80) made from a material capable of desolidifying upon the application of heat, such as a wax pttern. The channel core pattern (80) is shaped to provide the desired channels (30) within the refractory inductor block (20). After formation of the green refractory, the mold material, such as wax, may be melted off and the refractory cured by firing at a temperature to from 760 to 871 °C. (1400 to 1600°F), preferably about 815.5 °C. (1500°F), for from 5 to 20 hours and preferably about 6 hours. To ensure temperature uniformity during firing, the temperature is slowly raised from ambient up to the firing temperature at a rate of up to 5.6 °C. per hour.

摘要： A method and apparatus for using a channel induction furnace (10) in casting steel. In the method, material is charged directly into the furnace (10) to replenish a bath of molten steel therein. Preferably the material is steel scrap and the scrap is charged into the furnace (10) through a hopper located above the furnace which may also act to vent furnace gases thereby drying and preheating the scrap. Molten steel may be poured directly into a tundish (80) associated with a steel casting apparatus (12). Two inductors may be mounted on the furnace (10) and individually detachable to allow continuous operation of the furnace while one or the other inductor is being replaced. Two channel induction furnaces may be used as melting furnaces and a third used as a holding furnace fed from the melting furnaces. Preferably horizontal casting apparatus is used together with reheating and continuous rolling.

摘要： A channel induction furnace, particularly for melting aluminium has a pair of U-shaped channels (11, 12) extending downwardly from the bath (10). The channels have a radial width, measured outwardly from the axis of the core (13), which is several times the penetration depth in the molten metal for a current of the energising frequency and the channel section is tapered so that the channel is wider near the core and narrower away from the core. The planes containing the axes of the channels are skewed about an axis of skewing normal to the axis of the core. The large radial width gives a non-uniform current distribution resulting in flow patterns across the channel. The tapering provides an unbalanced electromagnetic pressure between the base of the loop and the bath and generates a further flow pattern whilst the skewing produces unidirectional flow through the channel. The combined effect enables high power to be put into the inductor without causing any pinch effect resulting in breaking of the metal path along the channel.

摘要： The invention comprises a double loop channel type induction furnace of which the floor has a base on a first side of its hearth and a ramp which rises from the base to terminate in a plateau above the passages at a location distal from the first side. The ramp and plateau extends at least partly between opposing end walls of the furnace, and the plateau includes a trench which extends at least partly between opposing ends of the plateau. The trench is in fluid communication with the passages and the bottom of the trench is located in a plane higher than the plane in which the furnace floor is located. The base of the furnace floor is in fluid communication with the central passage by means of a floor passage that extends from the base of the floor to the central passage through the ramp below the trench.

摘要： An induction furnace capable of drawing large diameter preforms of up to 130 mm is described, including top and bottom chimneys surrounding the entire preform during operation of the furnace with an inert conditioning gas; the latter is introduced into the top chimney and flows downward through the furnace body and bottom chimney without significant turbulence. A distributor ring inside the top chimney redirects flow from a circumferential direction to a downward direction. The top chimney also includes a resilient seal to releasably hold the top of the preform. The bottom chimney has a smoothly decreasing cross-sectional area preventing turbulence at the furnace exit. The furnace insulation is preferably a rigid self-supporting graphite cylinder. A method of drawing large diameter preforms either to an optical fiber or to a preform of smaller diameter using such a furnace is also claimed and disclosed.
