The utility model provides a tundish clamping fixture. The tundish clamping fixture comprises a clamping fixture body, a lug boss is arranged on one side, close to the injection groove, of the mould body; a first groove perpendicular to the bottom face is formed in the side wall of the side, away from the protruding part, of the clamping fixture body, a first gap is formed between the protruding part and the injection groove, and a second gap is formed between the first groove and the inner wall of the tundish. In the working process, the mould body is suspended into a tundish to form a first filling space, the first filling space is filled with a dry material, and the dry material is heated to be hardened to form an erosion layer. By additionally arranging the first groove, the first gap has a larger size, so that a thicker dry material erosion layer is formed, it can be guaranteed that the overall thickness of the dry material erosion layer is larger than the critical thickness under erosion of molten steel
