The invention relates to a
continuous casting protection
casting device of high-quality steel, which belongs to
molten steel casting equipment, and particularly relates to a
continuous casting protection
casting device for the high-quality steel. The
continuous casting protection casting device is characterized in that an elastic corrugated
pipe is arranged on an iron casing, a water outlet is surrounded by the corrugated
pipe, and an annular
asbestos sealing
gasket is arranged on the upper end of the corrugated
pipe, is abutted below a steel
ladle and is opposite to a steel outlet; a conical
asbestos sealing ring is arranged in the
contact position of the water outlet and a long water opening, and the long water opening, the elastic corrugated pipe, the
asbestos sealing
gasket, the water outlet and the asbestos sealing ring form an elastic
argon gas sealing chamber. The continuous casting protection casting device has the advantages that the elastic
argon gas sealing chamber which is provided with an
argon gas inlet and is formed by the elastic corrugated pipe, the asbestos sealing
gasket and the asbestos sealing ring is arranged between the water outlet and the long water opening, so that
molten steel is effectively prevented from being contacted with air, the argon sealing effect is enhanced, secondary oxidation of the
molten steel is avoided, smooth continuous casting production is guaranteed, inclusions in steel are reduced, the quality of the molten steel is improved and improved, and the requirement of high purity of the high-quality steel is satisfied.
