Procedure for obtaining raw material resulting from waste material

Abstract

The procedure (1) for obtaining raw materials resulting from waste material comprises: the supply (A) of harmonic steel resulting from waste material and prepared in a skein to be treated (3); a heat treatment (B) of the skein to be treated (3) for obtaining a treated skein (3a);—a post-treatment (E) of the treated skein (3a) for obtaining steel reusable as raw material; where the heat treatment (B) comprises an inductive exposure step (B1) of the skein to be treated (3) to at least an alternate magnetic field for the induction in the skein to be treated (3) of alternate eddy currents adapted to raise the temperature of same.
