Monolithic Refractory Coating for Tundish as Working lining
The Description:
Coating is a material that is coated on the surface of an object to form a protective and decorative film. In addition to its protective and decorative functions, the coating can also have some special functions, such as being used as a color marker, lubrication, anti-slip, insulation, electrical conductivity, heat insulation, moisture-proof, etc.

Classification:
There are many varieties of light fire resistant spray coatings, mainly clay, ceramite and perlite fire resistant spray coatings. Clay refractory spray coating is divided into porous clinker, light brick sand and clay clinker and perlite mixed aggregate. This kind of material is widely used, mainly used in blast furnace, hot blast furnace and heating furnace and other thermal equipment insulation layer, and can be used in petrochemical pipe heating furnace, flue and chimney working layer.
