High-durability submerged fused silica nozzles for continuous steel casting machines : Design, fabrication and service

A procedure is developed for the manufacture of submerged fused-silica nozzles with a ceramoconcrete structure by centrifugal modling. Made in open-bottom and blind-bottom designs, the nozzles can withstand the casting of 6–8 heats of steel with 0.8–1.0% manganese. The proposed nozzles offer a level...

Description
Summary:A procedure is developed for the manufacture of submerged fused-silica nozzles with a ceramoconcrete structure by centrifugal modling. Made in open-bottom and blind-bottom designs, the nozzles can withstand the casting of 6–8 heats of steel with 0.8–1.0% manganese. The proposed nozzles offer a level of durability comparable with that of imported Vesuvius Co. nozzles at a quarter of their cost.
