A coreless induction furnace that is automatically adjustable during assembly operations or melting operations. The furnace may include an outer shell, a set of adjustable shunt systems that operably engages with the outer shell, at least one cooling coil that operably engages with the set of adjustable shunt systems, and a power coil that operably engages with the at least one cooling coil and the set of adjustable shunt systems. The furnace is configured to automatically adjust at least one shunt of the set of adjustable shunt systems relative to at least one of the at least one cooling coil and the power coil. The furnace may also include an adjustable head system that operably engages with the outer shell. The adjustable head system is configured to automatically adjust a head of the adjustable head system relative to the at least one cooling coil and the power coil.

Methods of monitoring pressure on one or both of a shunt and a head of an induction furnace during a melting process. Methods include steps of engaging at least one shunt drive assembly with a support column and the shunt or engaging at least one head drive assembly with an apron and the head. Methods may also include steps of providing at least one load cell with the shunt at a first position and with the at least one shunt drive assembly or at least one load cell with the head at a first position and with the at least one head drive assembly. Methods may also include connecting a controller with the at least one load cell of the shunt system and/or the head system. Methods may also include connecting the controller with the at least one shunt drive assembly and/or the at least one head drive assembly.

An adjustable head system of an induction furnace and method of use thereof. The adjustable head system includes a head, an apron that operably engages with an outer shell of the induction furnace, and at least one head drive assembly that operably engages with the apron. The at least one head drive assembly is configured to automatically adjust the head along an axis angled relative to the apron upon assembly of the induction furnace, upon disassembly of the induction furnace, or during a melting operation of the induction furnace.

A magnetic induction furnace configured to heat solid or tubular metal billets, of various lengths and diameters, made of non-ferrous materials. The furnace includes a fixed body in which there is arranged an electric motor having an annular rotor rotatably disposed in a stator. The annular rotor is joined to a rotor body carrying a plurality of permanent magnets arranged so as to define a hollow magnetic cylinder having a cavity configured to contain a non-rotating billet to be heated. The permanent magnets of the rotor body comprise main permanent magnets magnetized in the radial direction with respect to such rotor body and auxiliary permanent magnets magnetized in the axial direction. The permanent magnets generate flux lines of a magnetic field directed inwardly, towards an interior of the cavity configured to contain the billet so as to improve the heating thereof.
