Overview

What are Rice Husk Ash Pellets?

Rice Husk Ash Pellets are uniform, extruded pellets of high-silica rice husk ash, engineered for steel mills that need clean, free-flowing insulation with minimal dust and easy mechanized handling. Compared to loose powder, the pellet form feeds evenly through automated systems, keeps the melt-shop floor dust-free, and packs at higher density for lower storage and freight cost.

Used as an insulating cover over molten steel in ladles and tundishes, the pellets retain heat and cut radiation losses, helping maintain consistent metal temperature. Their uniform size gives even coverage, while reducing skull formation and preventing re-oxidation of the metal — protecting metal quality and improving yield.
