The dry vibrating material for the tundish is used as the working lining material for the tundish. The particle grading is designed based on the principle of the closest stacking, and high-quality magnesium sand, magnesium calcium sand, and magnesium olive sand are selected as the main raw materials, and solid resin and other binders are added to prepare it. This 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 the working layer material of the tundish on the molten steel. The service life is between 8 hours and 40 hours. Manufacturer of fused magnesia
