Abstract
A tundish consisting essentially of a rigid metallic outer casing having walls and a bottom at least one permanent layer of heat insulating material adjacent said casing, and a unitary, integrally formed expendable inner lining made of a hydrocarbon-free refractory composition and having at least one liquid metal flow control device integrally formed therewith, the lining being chemically compatible with the molten metal to be placed in the tundish. The invention also comprises the unitary integrally formed expendable lining and the method to form the same.
Claims6
A tundish consisting essentially of a rigid metallic outer casing, at least one layer of permanent heat insulating material adjacent said casing, and a unitary, integrally formed inner expendable lining and at least one expendable liquid metal flow control device of a hydrocarbon-free refractory composition said unitarily formed expendable lining and control device being structured so as to be removable from the tundish at the same time and, said composition being chemically compatible with the molten metal to be placed in the tundish.
A unitary, integrally formed expendable unitary tundish lining and at least one expendable liquid metal flow control device for the interior of a tundish consisting essentially of a hydrocarbon-free refractory composition, said composition being chemically compatible with the molten metal to be placed in the tundish.
