Tundish Covering agent


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.


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 .
