Ladle & Tundish Insulation
RICE HULL ASH
Drastic reduction in radiant heat loss due to reflective black cover
Thermal convection insulation for steel- and iron-making
Physical barrier to open air exposure of hot metal or slag
The most cost-effective insulator on the market today
Rice Hull Ash Insulating Powder Benefits
Self-leveling and self-spreading ∙ Extremely low consumption rate due to high melting point and low bulk density ∙ Enables continuous casting sequence NOT limited by surface conditions ∙ No adherance to or coating of basic refractories ∙ Reduces skull formation ∙
Extends the fluidity and utility of the refining flux when used on engineered slag
