A Turbulence Controller for Asymmetric Continuous Casting Tundish

Abstract

The invention discloses a turbulent flow controller for an asymmetric continuous casting tundish, and belongs to the technical field of ferrous metallurgy. The turbulent flow controller for the asymmetric continuous casting tundish comprises a cavity, wherein a rectangular cavity body is formed inside the cavity. The rectangular cavity body is communicated with the exterior of the cavity through an opening at the upper end of the cavity. An intracavity inclined surface is arranged between the bottom surface and one side surface of the rectangular cavity body. A front brim protruding inwards is arranged at the opening end of the portion, above the intracavity inclined surface, of the cavity. Front brims protruding inwards are arranged at the opening end of the portions, on the left side and the right side of the intracavity inclined surface, of the cavity. A cavity opening inclined surface is arranged at the opening end of the portion, not provided with the front brims, of the cavity, and the inclination angle of the cavity opening inclined surface is 10-80 degrees. By adopting the turbulent flow controller for steel production continuous casting, a production process is simple. The turbulent flow controller is especially suitable for the occasions where requirements for uniformity of molten steel temperatures and constituents of outflow ports are high, flow conditions of molten steel can be controlled effectively, and asymmetric distribution of the molten steel can be achieved.

Description

technical field [0001] The invention belongs to the technical field of iron and steel metallurgy, and in particular relates to a turbulent flow controller for an asymmetrical continuous casting tundish. Background technique [0002] The continuous casting tundish is the last refractory material reactor before the molten steel solidifies, and the metallurgical transmission behavior in it directly affects the quality of the continuous casting slab. [0003] A qualified continuous casting tundish should be able to realize the following functions: [0004] 1. Promote the mixing of molten steel composition and temperature, and realize the uniformity of molten steel temperature and composition at each outlet of the continuous casting tundish; [0005] 2. Promote the collision aggregation and floating removal of inclusions in steel; [0006] 3. When the ladle is pouring, changing the ladle or performing high-speed continuous casting, it can control the strong turbulent flow cause...
