Applications of Rice Husk Ash
Application in continuous casting process
Rice husk ash (RHA), a byproduct rich in silica, is an effective insulation material in the continuous casting process, particularly as a tundish and ladle insulation agent. Its low thermal conductivity and lightweight, porous nature help minimize heat loss, maintain molten metal temperature, and prevent oxidation during metal transfer. RHA is cost-effective, environmentally friendly, and promotes energy efficiency, making it a sustainable alternative to synthetic insulators. While its effectiveness depends on controlled processing for high-purity ash, RHA significantly enhances metal quality and reduces industrial energy consumption.
