摘要： A degassing apparatus having duplex vacuum vessels for removing impurity gases from molten steel by backflow of molten steel thereby homogenizing molten steel composition. The apparatus includes duplex vacuum vessels of first and second vacuum vessels fixedly arranged at a predetermined interval to a floor which is provided horizontally at a predetermined height from a bottom; first and second ladle carriages arranged to run on first and second rails, respectively, to reciprocate between a treatment position directly under the first and second vacuum vessels and a tapping position where refined molten steel is tapped, each of the first and second ladle carriage loaded with a corresponding one of first and second ladles; and first and second lifting cylinders each for raising and lowering each of the first and second ladles in the treatment position so that a bottom end of each of the first and second vacuum vessels is immersed by molten steel in each of the first and second ladles. The apparatus can remove limiting factors of suspending a continuous vacuum degassing refining process and thus prolong lifetime of the vacuum vessel and save manufacturing cost.
