Abstract
The nozzle includes a chimney whose upper end is connected to the output nozzle of a vessel containing liquid metal and whose lower end is connected to a terminal part of the nozzle provided with outlets for distributing liquid metal into the casting space defined by the mold. The terminal part includes, in its upper region, at least one opening for allowing the reheating of the inside of the terminal part by a burner. The nozzle is particularly adapted for use with a bottomless mold having intensively internally cooled walls, and is preferably made of a refractory material.
