Abstract

PURPOSE:To make stable operation possible through prevention of erosion of refractory plates by constituting the zone of a sliding nozzle where the generation of erosion owing to negative pressure or vortexes is anticipated of refractories contg. no free carbon. CONSTITUTION:In the case of performing continuous casting in a tundish using a sliding nozzle (SN) device consisting of a stationary plate 4 and a sliding plate 1, it is often the case the molten steel is throttled and charged into the tundish by regulating the opening of the SN device. At the time when the molten steel flows down in the nozzle part, the throttled flow expands in the hole of the lower plate and develops negative pressure under throttling, and voltexes are procuded by including air through sliding surfaces, etc. The refractory plates 1, 4 consisting of Al2O3-C, etc. and the parts 2 where joint materials consisting of tar, etc. are vulnerable to erosion are constituted of refractories 3 contg. no free carbon such as zirconia, whereby the erosion is prevented.
