HOT-EXTRACT APPARATUS FOR HOLLOW INCONEL-BILLET BY CENTRIFUGAL CASTING

The present invention relates to a system for hot-extruding a hollow Inconel billet by centrifugal casting and, more specifically, to a system for hot-extruding a hollow Inconel billet by centrifugal casting, which comprises: a centrifugal casting apparatus manufacturing a hollow billet; a cutting processing apparatus removing impurities from the inner and the outer circumferential surface of the billet, which was manufactured by the centrifugal casting apparatus, by grinding the inner and the outer circumferential surface; a heating apparatus heating the billet of which the surfaces were processed by the cutting processing apparatus; an extruding apparatus extrusion-molding the billet which was heated by the heating apparatus; and a cutting apparatus cutting the billet, which was extruded by the extruding apparatus, at an appropriate size, wherein the heating apparatus as a high-frequency heating apparatus includes: a body; a through-hole installed in the body longitudinally, formed into a cylinder, and having the billet inserted thereinto; a pair of guide rails longitudinally formed on the lower inner circumferential surface of the through-hole, and guiding the transfer of the billet; and a coil installed to be inserted around the through-hole in the body, and heating the billet positioned in the through-hole, and the extruding apparatus for an extruding step of extrusion-molding the heated billet includes: a mounting unit having the heated unit mounted in a hollow hole therein; a discharge unit discharging the billet after extruding the billet, which is mounted in the mounting unit, at a desired diameter; and a push unit installed on the front side part of the mounting unit, and pushing the billet so that the billet mounted in the mounting unit can be discharged to the outside through the discharge unit.
