Furthermore, a feed hopper is arranged in the middle of the filter plate and is made of a heat-resistant metal material.

The utility model has the advantages that: the flow restraining plates are arranged in the tundish body and distributed in a V shape, so that the molten steel is stabilized under the action of the flow restraining plates, the convex blocks are arranged at the middle positions of the two flow restraining plates, meanwhile, the overflow holes are arranged between the flow restraining plates and the bottom end in the tundish body, and the molten steel is favorably and completely discharged under the action of the convex blocks and the overflow holes.

The stepped block is arranged at the bottom end of the inner part of the tundish main body, so that molten steel can be discharged under the action of the stepped block, and the molten steel allowance in the tundish main body can be reduced.

The opening of the tundish body is provided with the filter plate, so that scum suspended above molten steel can be taken out under the action of the filter plate, and meanwhile, the filter plate can be taken out by utilizing the fact that the inclined plates symmetrically arranged on the filter plate are matched with the inner wall of the tundish body and the inclined plates are provided with the hanging rings.
