摘要： Disclosed is an induction furnace with improved circulation of the molten metal. The increased circulation and is achieved by positioning the greatest magnetic field strength in a location above one or more of the channel vertical legs. This arrangement is achieved by (a) using an angled core to position the field over the upper channel opening or (b) by positioning the upper channel leg opening by lowering the channel opening to within the magnetic core window.

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： A channel furnace for the inductive heating of metal includes a molten metal holding hearth and a core and coil assembly surrounded by a channel of the furnace for inducing heating current in the metal in the channel. The channel is separated from the core and coil assembly by a refractory insulator and a bushing interposed between the refractory insulator and the core and coil assembly. The bushing is comprised of a wall portion having a plurality of slits or gaps disposed in the wall for minimizing eddy current formation therein and correspondingly reducing power loss therefrom. The bushing can be configured as either a coil type comprised of a plurality of slits disposed to extend circumferentially or a cage type, wherein the slits are disposed to extend longitudinally for segregating the wall into a plurality of wall sections. Both types can be made of water cooled flat metal tubes instead of plates with slits.

摘要： A high frequency core and coil electric metal melting furnace is shown. This furnace has a lined channel in its inductor for carrying the molten metal. The invention provides an improved inductor for a core and coil furnace that is not subject to leakage of the molten metal from the channel into the rammed refractory support bed for the channel which leakage otherwise shortens the lift 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： The invention relates to channel induction furnaces employed for melting metals.A channel is arranged to extend downwardly from a bath and to form a loop whereby molten metal in the bath can pass into the looped channel to form a closed electrically conducting loop. A laminated iron core passes through a coil and forms a closed magnetic circuit linked with the coil and channel. Consequently, alternating current applied to the coil induces currents to flow in the molten metal in the channel, which metal is therefore heated. The molten metal is contained in the channel within a refractory lined vessel. With application of the alternating current to the coil electromagnetic forces are produced which are directed away from the walls of a channel. Thus a squeezing action is applied to the metal which produces an increase in static pressure towards the center of the channel relative to that at the wall. This pressure fluctuates from zero to a maximum value at twice the frequency of the induced current. For some value of these forces, the minimum wall pressure will be less than the vapor pressure of the most volatile species in the molten metal. Thus a vapor filled cavity can grow on the wall facing the core and upon collapse can damage the refractory lining of the channel. Therefore, to overcome this problem the channel wall nearest the induction core is shaped to follow a contour of constant current density or to follow a contour of constant static pressure.
摘要翻译：本发明涉及用于熔化金属的通道感应炉。通道布置成从浴槽向下延伸并形成环，其中浴中的熔融金属可以进入环形通道以形成封闭的导电环路。层叠的铁芯通过线圈并形成与线圈和通道相连的闭合磁路。因此，施加到线圈的交流电流引起电流在通道中的熔融金属中流动，因此该金属被加热。熔融金属容纳在耐火材料衬里容器内的通道中。通过向线圈施加交流电，产生远离通道的壁的电磁力。因此，挤压作用被施加到金属，其相对于壁处的静压力相对于通道的中心产生静压增加。该压力从零到感应电流频率的两倍的最大值。对于这些力的一些值，最小壁压将小于熔融金属中最易挥发的物质的蒸气压。因此，蒸汽填充的空腔可以在面向芯的壁上生长，并且在崩溃时可能损坏通道的耐火衬里。因此，为了克服这个问题，最靠近感应核心的通道壁被成形为遵循恒定电流密度的轮廓或遵循恒定静压力的轮廓。

摘要： Valve means for ladles or furnaces, preferably of channel type, provided with at least one bottom tap hole. This means comprises a magnetic circuit with an ''''air gap'''' in the hole and with a flux direction straight across the flow direction in said hole. Current conductors are also arranged to conduct electric current straight across the stream, perpendicular to the flux, and a force is thus produced in the melt in the hole directed upwards or downwards and depending on the law of magnetic force. The invention also includes an embodiment with similar means in a channel type furnace, but used for circulating molten metal in the channels of the furnace.
