摘要： PURPOSE:To recover Ar in high purity and at low cost and to reduce the cost of molten steel treatment by using water freed of dissolved air as the water for cooling a condenser of an evacuation apparatus wherein Ar is separated and recovered from the waste gas of the vacuum degasing equipment, and circulated and reused. CONSTITUTION:An inert gas 5' such as Ar is blown into suction pipe 2-1 at the lower part of a vacuum vessel 1, and molten steel 4 in a ladle 3 is successively sucked and continuously degasified. In this case, the inside of the vessel 1 is kept at 1-100mm.Hg, and the recovery of Ar is improved by reducing the N2 content in the waste gas from the vacuum degasing equipment. Namely, water freed of dissolved air in an evacuation apparatus is used as the water for cooling the condenser of the evacuation apparatus in order to reduce the N2 content in the waste gas. Besides, the waste gas condensed with the dissolved air-free water is stored temporarily in a storage tank, and then Ar is separated in an AR separator. The recovered Ar is circulated and reused as the gas for circulating molten steel, cooling the O2 lance, and sealing.
