Abstract
A shaping machine includes a melting vessel, an induction coil arranged on the melting vessel for inductively heating, in particular melting, a material, and a shaping cavity. The melting vessel has at least one irradiation region which is substantially permeable for an electromagnetic field, and the shaping machine is adapted to cool the material in the cavity in such a way that a substantially crystalline solid body is formed. A body with a higher magnetic permeability than the melting vessel is arranged overlapping the irradiation region, and the induction coil is arranged between the body and the irradiation region.
Claims26
A shaping machine comprising:
- a melting vessel having an irradiation region permeable to an electromagnetic field, the irradiation region being formed of an opening in the melting vessel;
- an induction coil arranged on the melting vessel for inductively heating a material;
- a shaping cavity;
- and
- a body having a higher magnetic permeability than the melting vessel, the body being arranged to overlap the opening forming the irradiation region of the melting vessel without surrounding the melting vessel, and the induction coil being arranged between the body and the irradiation region;
- wherein the shaping cavity is configured to allow the material in the shaping cavity to cool such that a crystalline solid body is formed, and
- wherein the induction coil is arranged between the body and the irradiation region, and the body is configured to concentrate electromagnetic flux generated by the induction coil onto the irradiation region.
A method of inductively heating and crystalline hardening a material, the method comprising:
- providing a melting vessel having an irradiation region permeable to an electromagnetic field, the irradiation region being formed of an opening in the melting vessel;
- arranging the material in the melting vessel and inductively heating the material by an induction coil;
- and
- cooling the material in a shaping cavity such that a crystalline solid body is formed,
- wherein the providing of the melting vessel includes arranging a body in an overlapping relationship with the irradiation region such that the body overlaps the opening forming the irradiation region of the melting vessel without surrounding the melting vessel, the body having a higher magnetic permeability than the melting vessel,
- wherein the providing of the melting vessel further includes arranging the induction coil between the body and the irradiation region and configuring the body to concentrate electromagnetic flux generated by the induction coil onto the irradiation region.
A method of using an arrangement comprising a melting vessel and an induction coil arranged on the melting vessel to treat a material, the method comprising:
- providing the melting vessel with an irradiation region permeable to an electromagnetic field, the irradiation region being formed of an opening in the melting vessel;
- arranging a body having a higher magnetic permeability than the melting vessel in an overlapping relationship with the irradiation region such that the body overlaps the opening forming the irradiation region of the melting vessel without surrounding the melting vessel;
- arranging the induction coil between the body and the irradiation region and configuring the body to concentrate electromagnetic flux generated by the induction coil onto the irradiation region;
- and
- inductively heating and crystalline hardening of the material by the arrangement.
