Product description

Tundish Covering agent :

   1) Thermal Insulation, Preventing Incrustation of Tundish Molten steel.

2)        Insolated from the air, Prevented Secondary Oxidization of Molten steel.  Reduce the Content of Inclusions in molten steel.

3)        Adsorbed No-Metallic Inclusions in Molten steel.

4)        fast spread the surface of Tundish ,Less consumption thus reduce the production cost .
