摘要:
An induction melting furnace having an asymmetrical sloping bottom. The melting furnace includes: an induction coil member provided on the melting furnace so as to melt waste contained in the furnace by vitrification; a bottom unit provided in a lower part of the melting furnace, the bottom unit asymmetrically sloping downward in a direction toward a glass discharge port that is formed through the bottom unit; and a cooling member integrated with the bottom unit. Due to the asymmetrical sloping bottom of the furnace, waste in the furnace can be completely melted and can be easily discharged to the outside and, accordingly, the time and cost required to treat the waste are reduced and this improves work efficiency when treating the waste. Further, due to the insulation material, the melting furnace can be protected from electric damage that may be caused by electric arc.

The present invention provides a metal sector and a cold crucible induction melter having the same. The cold crucible induction melter includes a wall formed of a plurality of metal sectors insulated by an insulator. Each metal sector includes an inner curved portion which forms an inner surface of the wall and is convex inward relative to the wall, an outer planar portion which forms an outer surface of the wall, and a side planar portion which connects the inner curved portion to the outer planar portion.

A molten glass discharging device provided in the bottom of a melting furnace of a waste vitrification apparatus so that the device can control the melting or cooling of a molten material. The molten glass discharging device, which is provided in the bottom of the furnace and controls discharging of a molten material, includes: an induction heating unit (110) having a discharging passage (10) along a discharging port formed in the bottom of the melting furnace; an induction coil (120) provided outside the induction heating unit (110); and a cooling unit (130) supporting the induction heating unit (110) and having a cooling conduit through which a cooling fluid circulates. The device can realize repeated discharging of the molten material by induction heating or cooling of the induction heating unit. Further, even when glass is adhered to the discharging port, the adhered glass can be easily discharged from the furnace.
