Rice Husk Ash Granules
Free-flowing, high-silica RHA granules engineered as an insulating tundish covering compound and ladle covering compound for the steel industry — supplied to a consistent, NABL-tested spec.
What are Rice Husk Ash Granules?
Rice Husk Ash Granules are a granulated, high-silica form of RHA with controlled granulometry and excellent flow, formulated for use as a covering compound on molten metal.
Spread over the steel surface in the tundish or ladle, they form an insulating, non-wetting layer that reduces heat loss, prevents re-oxidation and helps absorb inclusions — protecting metal quality and improving yield.
As a tundish covering compound and ladle covering compound supplier, Ambika Biotech ships a consistent, NABL-tested granule with reliable bulk availability and full export documentation.
