| 摘要 |
According to the present invention, a raw material melting apparatus includes: a melting furnace having an internal space for melting a raw material; a discharging passage which is installed in the furnace and discharges melt molten in the melting furnace to the outside; and an exhaust air duct which is connected with the melting furnace and exhausts air by making gas in the melting furnace to pass through an area in which the discharging passage is located. According to an embodiment of the present invention, the exhaust air duct is installed so that the high temperature gas generated from the melt is discharged to the outside through the area in which the discharging passage is located. Thus, the present invention can prevent the discharging passage from being lowered by heating the discharging passage by the heat of the exhausted high temperature gas. Therefore, the present invention can prevent the discharging passage from being blocked due to the coagulation of the melt. |
