Abstract
An inductor to heat, by electromagnetic induction, an electrically conductive body, including an induction body, hollow inside, suitable to generate an electromagnetic field, the internal surface of which defines a containing seating, disposed through in a longitudinal direction.
Claims12
An inductor to heat, by electromagnetic induction, an electrically conductive body, wherein said inductor comprises:
- an induction body, provided with a coil suitable for the generation of an electromagnetic field inside it, wherein said coil is made as a hollow tube made by spirals,
- an insulating body conformed as a hollow tubular body disposed, during use, in a containing seating of said coil, suitable to be inserted into, and extracted from, said containing seating, and defining a transit channel for said electrically conductive body, and
- a containing body, configured to house said induction body and said insulating body, provided with apertures coherent with said transit channel, wherein said insulating body is removable from said induction body and wherein said inductor comprises a front head and a rear head, positioned respectively on a front face and a rear face of said containing body, provided with passage apertures aligned with said transit channel, wherein said front head and rear head are removable and are configured to be assembled onto and disassembled from said containing body to allow the insertion and extraction of said insulating body into/from said containing seating;
- and
- wherein said containing body comprises an upper aperture having a section suitable to allow the passage through it of said coil.

A method for the maintenance of an inductor, comprising:
- providing an inductor comprising:
- an induction body provided with a coil suitable for the generation of an electromagnetic field inside it, wherein said coil is made as a hollow tube made by spirals;
- an insulating body conformed as a hollow tubular body disposed, during use, in a containing seating of said coil, suitable to be inserted into, and extracted from, said containing seating, and defining a transit channel for said electrically conductive body, and
- a containing body, configured to house said induction body and said insulating body, provided with apertures coherent with said transit channel, wherein said insulating body is removable from said induction body and wherein said inductor comprises a front head and a rear head, positioned respectively on a front face and a rear face of said containing body, provided with passage apertures aligned with said transit channel, wherein said front head and rear head are removable and are configured to be assembled onto and disassembled from said containing body to allow the insertion and extraction of said insulating body into/from said containing seating;
- the method further comprising disassembling said inductor by removing the front head and rear head from said containing body;
- removing together said coil and said insulating body inserted inside it, wherein said coil and said insulating body are attached to one another and define an assembly which can be handled in its entirety;
- removing said assembly of said coil and said insulating body through an upper aperture of the containing body in a vertical direction;
- extracting at least said insulating body from said containing body;
- performing at least one maintenance operation on said coil, or a replacement of said insulating body;
- re-assembling said inductor by re-inserting the insulating body which had been removed, or inserting a new insulating body in said containing body;
- repositioning and attaching said front head and rear head to said containing body.
