Abstract
An apparatus for direct casting of strip from a pool of molten metal includes a tundish having a feed chamber, a return chamber and a diverting chamber. A lip insert is inserted into the tundish and has an open front for cooperation with a casting surface. The apparatus includes a control mechanism configured to control the surface level of the pool of molten metal in the diverting chamber and in the lip insert, and a movement mechanism configured to move the casting surface upwardly through the pool of molten metal for the casting of metal on the casting surface. The casting surface is an aluminum surface of a cylindrical drum and has a coarse irregular surface formed thereon by biasing with crushed, angular silicon carbide or aluminum silicate.
