Problems solved by technology

[0006] Most of the above-mentioned melt discharge devices and methods are used to discharge melts with low viscosity or easy to maintain viscosity such as glass, and are not suitable for discharging melts with much higher viscosity.
[0007] In particular, in the case of a molten material or a glass-ceramic molten material, its viscosity characteristic is significantly different from that of a glass molten material, so in the case of performing discharge by an existing method, when the molten liquid is exposed to the outside through the discharge port, The viscosity of the melt will increase sharply, causing the discharge to stop or not proceed smoothly
[0008] In addition, there is a problem that even if the discharge operation is performed, the molten material storage container cannot be filled accurately, and the molten material grows up inside the container like a stalagmite

Abstract

A tapping device and method using induction heat for melt comprises melting furnace made of steel; heating unit disposed in the upper part in the melting furnace and made of graphite material; induction coil wound around the heating unit; insulator disposed adjacent to the bottom surface of the lower part of the melting furnace; supporter disposed outside the insulator; and firebricks disposed on the bottom surface of melting furnace and outside the supporter.

Description

technical field [0001] The present invention relates to an induction heating type discharge device and method for molten material, in particular to a method for disposing the molten material discharge port at the lower part of the melting furnace, and setting the molten material discharge port higher than the bottom of the melting furnace so that the molten material is partially discharged Induction heating discharge device and method for molten material. Background technique [0002] Generally, as a method of discharging the melt inside the melting furnace, a method of discharging the melting furnace itself by tilting (tilting) or over an upper dam is used. [0003] In addition, there is also a method of discharging the molten material inside the melting furnace by removing a plug attached to the molten material discharge port, or securing the discharge port by oxidation heat of an oxygen lance or oxygen welding heat. [0004] Recently, a method of discharging a melt by an...
