摘要： An openable induction coil is provided. An electromagnetically shielded inductor assembly can be formed from the openable induction coil and an electromagnetically shielded enclosure into which the coil can be inserted. The induction coil can be pivoted open while in the shielding enclosure without complete disassembly of the enclosure. In some examples of the invention, a dynamic “curtain” of a gas is injected through spaces between opening portions of the coil and adjacent sections of the shielding enclosure, and into the interior of the induction furnace formed by the openable induction coil when it is in the closed position.

摘要： An apparatus and process are provided for inductively heating a workpiece to a desired cross sectional temperature. At least one pair of coils form a transverse flux inductor. The workpiece is located between the pair of opposing coils, which are oriented across the cross section of the workpiece. Each coil comprises a plurality of coil sections. The distance between one or more opposing coil sections is adapted to achieve the desired cross sectional induction heating temperature profile in the workpiece. Alternatively the distance between all opposing coil sections are equidistant from each other, and one or more flux concentrators, moveable at least in a direction perpendicular to the surface of the workpiece, can be used to achieve the desired cross sectional induction heating temperature profile in the workpiece.

摘要： An induction heating apparatus comprises a substantially gas-tight enclosure through which a workpiece passes. An induction means surrounds the exterior of the enclosure and an ac current flow though the induction means establishes a magnetic field that couples with the workpiece to inductively heat the workpiece. The gas-tight enclosure may comprise a non-electrically conductive material to permit passage of the magnetic field for coupling with the workpiece and an electromagnetic shield material for restricting the regions of the magnetic field. In alternate examples an electromagnetic shunt located around the induction means is used in place of, or in combination with, the electromagnetic shield material to restrict the magnetic field in a direction towards the workpiece. In other examples of the invention one or more flexible elements may be used with the non-electrically conductive material, for example, to compensate for thermal expansion of one or more process chambers adjacent to the gas-tight enclosure.

In a first embodiment, two coil sections each having a gap at one end for the strip material to pass edgewise into and out of the apparatus for heating wherein the coil sections are adapted for connection to two power supplies such that the first power supply connects through one half-turn of each of the coil sections, and thence to the second power supply, which is connected through the second half-turns of the respective coil sections and back to the first power supply, all in series. In a second embodiment, the coil sections are adapted for connection to four power supplies in series; each power supply connected to a respective half-turn of the coil sections, such that one half-turn is connected between each of the four power supplies. The series connection ensures uniform amplitude and phase of the electrical current applied to the induction heating coil apparatus.

摘要： A reinforced electric induction gas sealed tunnel furnace is provided. The assembled tunnel furnace has a tunnel wall that has the exterior wall transversely surrounded by structural reinforcing elements that give the tunnel structural strength to withstand a pressure differential between the interior and exterior of the tunnel, for example, when the tunnel interior environment is a vacuum and the tunnel exterior environment is at atmospheric pressure. One or more inductors form the induction coil system for the N tunnel furnace and can be located external to the tunnel wall, but within or adjacent to, the structural reinforcing elements. In alternative arrangements the structural reinforcing elements may be oriented with the length of the tunnel and installed either within or external to the tunnel. The tunnel and the structural reinforcing elements are sufficiently electromagnetically transparent to not interfere with inductive heating of a strip passing through the tunnel.

摘要： A variable width transverse flux electric inductor has a fixed powered coil section and associated box-like moveable passive coil sections that electromagnetically couple with magnetic flux generated by current flowing through the fixed powered section. The passive coil sections can be transversely moved across the workpiece to accommodate induction heating of workpieces having different widths or track movement of the workpiece. Alternatively the fixed powered coil section and associated moveable coil sections may be connected to each other through flexible connections, sliding contacts or other means, such as clamps, so that an electrical connection can be maintained between both in any relative position.

摘要： An electric induction gas-sealed tunnel furnace and process are provided. The exterior of the furnace's enclosure that forms a closed tunnel region is surrounded at least along its longitudinal length by a gas-tight barrier chamber that can be filled with a barrier gas to a different pressure than the pressure of the process gas in the closed tunnel region of the furnace. The inductors used to induction heat strips or plates in the closed tunnel region can be positioned within or outside of the gas-tight barrier chamber around the longitudinal length of the closed tunnel region.
