溶鋼の真空脱ガス装置。 Fine powder desulfurization agent is injected from below the ascending immersion pipe and descending immersion pipe provided at the bottom of the vacuum degassing tank through a blowing lance, and the molten steel rises together with injected gas. In a vacuum degassing device for molten steel that is blown into a stream, the above-mentioned injection lance is supported on the lower side wall of the vacuum degassing tank via a bracket, and is placed along the vacuum degassing tank and the vicinity of the rising side immersion pipe. A blowing lance for molten steel is provided with a blowing lance having a shape with a large curvature without bending points, facing the lower center of the rising side immersion pipe, and having the tip nozzle of the blowing lance facing upward. Vacuum degassing equipment.
