ABSTRACT:
The device for removing inclusions and especially oxides of the molten metal which is poured into a casting tundish comprises elements which are placed within the interior of the casting tundish and immersed in the molten metal. The elements are formed of heat-insulating material which is sinterable at the temperature of the molten metal. A duct is formed within the interior of the elements and connected to a supply of gas such as argon which is inert with respect to the molten metal.
