Patent ID: 6860317

Claim:
A method for producing a uranium foil, comprising the steps of: (a) charging a furnace installed in a sealed chamber with uranium alloy, forming a vacuum in the chamber, and heating the chamber by means of a high frequency induction coil so that the uranium alloy is melted in the chamber; (b) elevating a stopper installed in the furnace so that the molten uranium alloy is discharged from the furnace into a turn dish below the furnace, and gravitationally dropping the molten uranium alloy as a foil shape at a designated speed via a slot of a nozzle installed in a bottom surface of the turn dish; (c) feeding the foil into a gap between a pair of cooling rolls located below the slot within the chamber and rotated in opposite directions so that both sides of the foil respectively contact the cooling rolls to be rapidly cooled; and (d) collecting the cooled foil by a collection tray located below the cooling rolls at a bottom of the chamber.
