It is disclosed and induction furnace (1) comprising: a box-like housing structure (2, 6), which defines an internal chamber (3) of the induction furnace (1); an infiltration crucible (7) housed in the internal chamber (3) and comprising a first (10) and second (11) essentially mutually parallel and spaced away radiation plates, made of susceptor material, and an infiltration chamber (13), which is interposed between the radiation plates (10, 11) in order to be heated by the plates, the infiltration chamber being provided for housing a semifinished workpiece (14), to be subjected to infiltration, and infiltration material (15); at least an induction coil (L1, L2) housed in the internal chamber (3) to be supplied with at least an electrical current (i1, i2) for induction heating of the radiation plates (10, 11). The induction coil (L1, L2) comprises a first (L1) and second (L2) spiral induction coil, each of the spiral coils (L1, L2) being positioned at a relatively shorter distance with respect to a respective associated radiation plate (10, 11) and at a relatively longer distance with respect to the other radiation plate (10, 11). |
