INSULATING POWDERS

RICE HULL ASH

Drastically reduces radiant heat loss through reflective black cover practice
Thermal convection insulation
Physical barrier to air infiltration to molten metal or liquid slag
RHA is the most cost-effective insulator on the market today

Other Facts About Rice Hull Ash

Self-leveling and self-spreading ∙ Unrivaled ability to float on a molten surface ∙ Extremely low consumption rate due to high melting point and low bulk density ∙ Allows for a continuous casting sequence NOT limited by surface conditions ∙ Rice Hull Ash does NOT adhere to or coat to basic refractories ∙ Decreases adherence to splash skulls during tap process ∙ Reduces skulls and clean dumping ∙ Extends the fluidity and utility of the refining flux when used on an engineered slag
