A STRUCTURE OF REFRACTORY FOR SNORKEL OF RH-OB

摘要

The present invention relates to a refractory construction structure of the immersion pipe which is immersed in the molten steel in RH-OB device of iron and steel plant.; The present invention, shaped refractory Alpenblick which is mounted on the inner surface of blood iron forming a deposited tube;; The iron is attached the outer surface of blood multiple-sheet partition-like carbon-based Alpenblick in which the;; And; form a conical inclined surface corresponding to the top of the conical slope of the carbon-based Alpenblick and upper support fixed to the cheolpi to secure the dividing the carbon-based Alpenblick cheolpi; It provides the refractory construction of the structure RH-OB immersion tube containing; lintel member provided on the iron of the annular blood bottom to support a lower end of the carbon-based stepped Alpenblick.; According to the present invention, the thermal shock resistance to be applied by immersion of the tube from below the molten steel becomes excellent, the content property with respect to the acidic slags are the excellent effect is obtained is improved so as to greatly improve the durability of the immersion tube.
