The refractory materials used in the tundish include the body of the tundish, the cover of the tundish, the upper and lower water outlets, the plug bar, the slag retaining weir and dam, the steady flow plate and the impact plate. The refractory materials used in the tundish are divided into lining refractory materials, continuous casting and prefabricated refractory materials.
Tundish is a vessel which can hold molten steel and distribute molten steel to continuous casting after ladle equipment. It is one of the important equipment of continuous casting process, so it is also called tundish of continuous casting.

The refractory parts used in tundish include ladle body, lid, upper and lower water outlets, plug bar, slag retaining weir and dam, steady flow plate, impact plate, etc. the refractory materials used in tundish are divided into lining refractory materials (working layer, permanent layer and insulation layer), continuous casting and prefabricated refractory materials. The physical and chemical indexes and performance of the refractory materials used in tundish vary due to different parts and use requirements Same as. High quality refractory is the premise to ensure the service life of continuous casting tundish. Revo can provide you with various refractory materials for tundish according to your requirements.
(1) Convenient construction, mechanized operation and high work efficiency

(2) Compact sintering, erosion resistance, erosion resistance, long service life

(3) It does not pollute molten steel and can meet the needs of clean steel continuous casting

(4) The working layer does not crack during use, and it is easy to turn over the package.
