Features: The product is dry-formed, quick in construction, smooth and smooth after construction, which can effectively reduce the pollution of molten steel in the working layer of the tundish. The product does not add water during the construction process, which can greatly shorten the time required for the tundish to be baked, thereby reducing fuel consumption. It is a new type of tundish lining material that has the potential to replace tundish coatings and insulation panels.
