Document Type and Number:
WIPO Patent Application WO/2010/032550
Kind Code:
A1
Abstract:
A melt refiner (1) which is for use in a ladling chamber (4) (holding chamber) that holds a metal melt (Y) therein and in which the metal melt is subjected to degassing and deslagging to heighten the degree of cleanliness of the metal melt and keep the amount of hydrogen gas small. With the melt refiner (1), the possibility that a slag generated is drawn up with a ladle or the like is low. The refiner is characterized by comprising: a cylindrical treating part (10) which is to be disposed in the ladling chamber (4) and has an opening (inlet hole) (13) through which the metal melt (Y) is caused to flow inward and an outlet hole (15) for discharging the melt outward; and a purifier (20) with which the metal melt (Y) inside the cylindrical treating part (10) is subjected to at least either degassing or deslagging. The refiner is further characterized in that the top of the cylindrical treating part (10) protrudes from the surface of the metal melt (Y) held in the ladling chamber (4).
