Abstract (en)
[origin: WO9835772A1] According to the method for avoiding contact between oxygen and molten metal, said molten metal pours into a casting chamber limited by walls (1, 2, 13) and flows out of it in the form of billet. In order to avoid any contact between oxygen and molten metal and thereby entirely prevent reoxydation, the oxygen trying to penetrate between the walls (1, 2, 13) and/or adhering to them (1, 2) is chemically reacted through possible splits (18) by using a compound with no adverse effect on molten metal (20).
