Abstract

The invention discloses a submerged nozzle swirl generator, a tundish and its application, comprising a swirl generator body with a stepped hole at the center of the top of the swirl generator body, and a top center of the swirl generator body Several blades are provided, one end of the blade is consistent with the curvature of the outer circle of the swirl generator body, and the end of the blade away from the outer circle of the swirl generator body is consistent with the curvature of the wall of the stepped hole, Moreover, a swirl cavity is formed between two pairs of the blades. Beneficial effects: the structure is simple, the design is reasonable, and the uniformity of the flow field distribution inside the submerged nozzle is improved, thereby significantly improving the stability of the molten steel flow in the crystallizer, thereby helping to improve the quality of steel products.

Description

technical field [0001] The invention relates to the technical field of metal smelting and processing, in particular to a submerged nozzle swirl generator, a tundish and its application. Background technique [0002] With the development of society, the requirements for steel performance are getting higher and higher. Improving the flow of molten steel in the tundish and continuous casting mold is of great significance for improving the quality and productivity of steel products. In the continuous casting process, the tundish and mold are the last metallurgical vessels for removing inclusions from molten steel. The flow field distribution of molten steel in the mold directly affects the removal of inclusions in molten steel and the solidification of molten steel in the mold. Among them, generating swirling flow in the mold can significantly optimize the movement state of molten steel in the mold, improve the solidification of molten steel in the mold, and thus improve the q...
