Abstract

A nozzle or tube (1) is useful for pouring molten metal, especially aluminum killed molten steel. The nozzle (1) is formed from a blend of doloma and graphite which is bonded together in a carbonized matrix. Nozzles or tubes (1) made in accordance with this invention have enhanced thermal shock resistance.
Furthermore, nozzles or tubes (1) of this invention resist the formation of aluminum oxide therein when they are used for pouring aluminum killed steel. Consequently, these tubes or nozzles (1) can be used in a continuous casting process for a long period of time without having to periodically stop the procedure and change the tubes (1) as they become blocked with aluminum oxide. As a result of the thermal shock resistance, the usual preheating step prior to contacting the nozzle (1) with the molten metal is greatly reduced.
