ABSTRACT:
A method for forming a nozzle employed in continuous casting is provided in which powder refractory materials are pressed with low hydrostatic pressure to produce preforms for an edge portion, an inner hole portion, and a powder line portion, these preforms are combined one after another in a rubber mold employing a mandrel while filling the rubber mold with a powdered refractory material for a body portion of the nozzle, and then a nozzle configuration is formed by pressing the rubber mold with a higher hydrostatic pressure than that used to produce the preforms.
