からの空気吸入防止装置。 An inert gas chamber is formed between the two packings by interposing a double packing on the inner and outer peripheries between a pair of flanges that connect the reflux pipe and the immersion pipe of the molten steel vacuum degassing equipment. A molten steel vacuum connected to an inert gas supply pipe having a valve and provided with a pressure gauge for detecting the pressure in the inert gas chamber, and configured such that the inert gas flow valve is operated by a signal from the pressure gauge. Device to prevent air inhalation from the immersion pipe joint flange of a degassing device.
