Production of nozzle for casting

Abstract

Abstract PURPOSE:To improve a nozzle for casting by calcining a nozzle material and interposing a ceramic fiber layer in the opposed parts of an outside peripheral part and inside peripheral part after consumption of a cylindrical flexible consumable material which is made thinner at the bottom end thereby forming the nozzle. CONSTITUTION:The cylindrical flexible consumable material 3 which is made thin at thickness at the bottom end and refractory powder 7 are thrown into a rubber mold 1 and the calcined after pressing. The ceramic fiber layer 7 is interposed in the opposed parts of the outside peripheral part 5 and the inside peripheral part 6 by the consumption of the flexible consumable material 3. The inside peripheral part 6 and the outside peripheral part 5 are thereby united again to one body. The inside peripheral part 6 and outside peripheral part 5 are simultaneously obtd. by the consumption of the flexible consumable material 3. The molding is made extremely efficient by using such nozzle for casting, by which the heat resistant nozzle by the intervention of the ceramic fibers is inexpensively produced. The thickness of the flexible consumable material is operated to be decreased, by which the intrusion of the molten metal is prevented.
