The tundish dry vibrating material is used as the tundish working lining material, which is designed based on the principle of the most compact stacking, and is prepared by using high-quality magnesia, magnesia calcium sand, and magnesium olive sand as the main raw materials, and adding solid resin and other binders. The product is formed by dry method, and the construction is fast. After drying, the surface is flat and smooth, which can effectively reduce the pollution of tundish working layer materials to molten steel. The service life is 8 hours to 40 hours.
