Title:

INDUCTION HEATING HEAD FOR MELTING AND SUPPLYING METAL MATERIAL

Document Type and Number:

WIPO Patent Application WO/2015/068936

Kind Code:

A1

Abstract:

The present invention relates to an induction heating head and, more particularly, to an induction heating head for melting and supplying a metal material. Specifically, the present invention relates to an induction heating head for locally heating a supplied metal material and supplying the same in the molten state. The induction heating head according to the present invention is applicable to various technological fields, including soldering, metal welding, and 3D printing using metal materials. The induction heating head for melting and supplying a metal material according to the present invention comprises: an induction heating coil to be electrically connected to a high-frequency power supply; and a magnetic core. The magnetic core is formed in the shape of a hollow cylinder using a magnetic substance so as to provide a path of a magnetic flux induced by the induction heating coil, and comprises an entry portion for supplying a metal material to the hollow interior and an exit portion for discharging the supplied metal material. The induction heating head according to the present invention, which comprises an induction heating coil and a magnetic core, can focus a magnetic flux for inducting heating and thereby melt and supply the exactly necessary amount of metal material.
