Abstract

The invention discloses a swirl generator with a submersed nozzle, a tundish and application. The swirl generator with the submersed nozzle comprises a swirl generator body and a step hole formed in the center of the top end of the swirl generator body, wherein a plurality of blades are arranged on the top of the swirl generator body; the curvature of one end of each blade is consistent to the curvature of the excircle of the swirl generator body; the curvature of the end, which is away from the excircle of the swirl generator body, of each blade is consistent with the curvature of the hole wall of the step hole; and a swirl cavity is formed between every two blades. The swirl generator with the submersed nozzle has the beneficial effects that the swirl generator is simple in structure andreasonable in design, homogeneity of distribution of inner flow fields of the submersed nozzle is improved, thus, stability of flowing of liquid steel in a crystallizer is improved remarkably, and the quality of a steel product is improved favorably.

Description

technical field [0001] The invention relates to the technical field of metal smelting and processing, in particular to an immersed nozzle swirl generator, a tundish and applications. Background technique [0002] With the development of society, the requirements for the performance of steel 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. During continuous casting, the tundish and mold are the last metallurgical vessels to remove inclusions from molten steel. The flow field distribution of molten steel in the mold directly affects the removal of inclusions in the molten steel and the solidification of molten steel in the mold. Among them, generating a swirl flow in the mold can significantly optimize the motion state of molten steel in the mold, improve the solidification of molten steel in the mold, and thus improve the quality...
