Abstract
An entry nozzle for transporting liquid metal from a tundish to a mould for the continuous casting of thin slab disposed therebelow, wherein the nozzle has a hollow channel therethrough, and at least at its lower outlet end, is, in plan section, of large aspect ratio of width to thickness, and is hollow substantially across its width, the entry nozzle being provided at positions at its lower outlet end arranged in operation to be submerged within the casting mould, with at least one exit port from the hollow channel disposed on each elongate side of the nozzle, and, with the nozzle in its operational disposition, so shaped as to direct metal into the mould from the nozzle transverse to its vertical disposition. With the process in its operating state the controlled effective liquid metal pressure head of the metal in the tundish provides a flow of such metal to the mould that, with the extraction rate of the solidifying metal from the metal forming means, creates a required level of metal within the mould.
