Structure for preventing continuous casting tundish from producing rotational flows
The invention discloses a structure for preventing a continuous casting tundish from producing rotational flows. The tundish is internally provided with a liftable rotational flow controller, and the rotational flow controller mainly comprises flow guide plates, a round disk and a lifting and pulling rod for lifting, wherein the round disk is horizontally positioned right above a water supply port in the tundish; a plurality of flow guide plates are symmetrically arranged on the lower surface of the round disk along the center and face to the center of the round disk; and the lifting and pulling rod is fixed in the center of the upper surface of the round disk. The round disk in the structure has the effect of fixing the flow guide plates on one hand and can cut off a passage generating the rotational flows on the other hand so as to compel molten metal to flow into the water supply port in a way of parallelism instead of perpendicularity to the bottom of the tundish. Therefore, the structure can fundamentally stop the generation of the rotational flows, which stops molten steel slag rolling and can obviously improve the casting blank quality under an abnormal pouring state, and meanwhile, the yield of the molten metal can also be obviously improved.
