Abstract: An improved submerged entry nozzle is provided which is useful in the casting of aluminum killed molten steel. The nozzle has an improved slagline sleeve or collar which surrounds the outer portion of the nozzle to protect it from corrosion during the casting process. The slagline sleeve is made from resin bonded zirconia/graphite which has been formulated so that upon curing of the resin to form resite, there is a reduction in the contractile tendency which results in a reduction in stress fracturing. The reduction of the contractile tendency and the resulting resistance to stress fracturing is achieved by adding an effective amount of calcium oxide to the resin-zirconia-graphite mixture which is used to form the sleeve.

Abstract: A continuous casting machine is provided that includes a refractory tundish funnel. The tundish funnel has a tapered shape and is designed to sit on a tundish lid in order to channel steel from the ladle to the tundish bath. A collector can also be provided to channel the steel from the ladle. The collector has an opening with a cross-section that transitions from a cylindrical shape to a cross-shape.

Abstract: A refractory discharge device includes an immersion nozzle formed substantially of carbon-bonded magnesium oxide or carbon-bonded aluminum oxide or fused quartz. The immersion nozzle has therethrough a discharge passage and has an outer surface and an outlet end. An external reinforcement member is formed entirely separately from the immersion nozzle from a zirconium oxide material that is directly bonded without any carbon and by burning at a high temperature. The external reinforcement member is attached to the outer surface of the outer surface of the immersion nozzle at a position such that during use the external reinforcement member will extend above and below a casting powder covering of molten metal into which the refractory discharge device will be immersed.
