Abstract

The invention provides a ladle bottom structure of a continuous casting ladle. The continuous casting ladle is provided with a cylindrical ladle (1) and a ladle bottom (2) sealing the bottom of the ladle (1), wherein the ladle bottom (2) is provided with a water port (3) penetrating the ladle bottom (2). The ladle bottom structure of the continuous casting ladle is characterized in that the ladle bottom (2) is provided with a slag baffling wall (4) adjacent to the water port (3), the height of the slag baffling wall (4) is equal to the critical height capable of producing a converging vortex at least, and the lower part of the slag baffling wall (4) is provided with a plurality of through holes (5) communicated with the water port (3). According to the ladle bottom structure of the continuous casting ladle, the formation of the converging vortex can be efficiently restrained, and the metal yield is enhanced. The ladle bottom structure of the continuous casting ladle has the advantages of simple construction, convenience in operation, long service life and low production cost.

Description

technical field [0001] The invention belongs to the technical field of iron and steel metallurgy, and in particular relates to a continuous casting ladle bottom structure capable of effectively suppressing the formation of converging vortices. Background technique [0002] During the continuous casting process, molten steel flows from the ladle into the tundish through the shroud protective sleeve. As the liquid level of molten steel drops in the later stage of pouring, converging vortices will be generated and intensified, which will promote the emulsification of slag and steel, and make the slag enter the tundish with the steel flow. The confluence vortex means that during the discharge process of the container, the liquid first descends vertically, and when it falls to a certain height, the liquid begins to converge toward the center line of the outlet, and forms a concave vortex on the surface of the slag layer. Generally known as "critical spin height" (hereinafter ref...
