Rice Husk Ash For Steel Productions & Foundry

Ladle & Tundish Covering Compound


KVINSUL-XP is a Low Carbon Rice Husk Ash Powder widely used in steel production as Heat insulator. It is a free flowing, nonhazardous powder made from Rice Husk Ash as main source of silica. It is also known as a Ladle / Tundish covering compound.

  •       Prevenet Heat Loss
  •       Absorbs nonmetal Impurities
  •       Prevents Re Oxidation of Metal
  •       Better Metal Quality


How It works?


KVINSUL-XP is Rice hsuk ash powder, being spread over molten metal which is usually at temperature of 16500 C while in Ladle/Tundish. It will create a thick layer of about 1”- 2” over molten metal and helps maintaining temperature of molten metal in process.
