Innsulekx Insulating Powder is a new generation product (Radex) made from rice husk ash / rice hull ash. Insulating Powder (Radex – also called Ladle Covering Compound) is used in steel mills for insulation of molten metal in ladle and tundish.

The temperature of molten metal in the ladle is around 1650 degrees centigrade (3000 degrees F) and above. When this metal flows from ladle to tundish the temperature drops considerably. Without the use of insulation cover material, there may be breakdown in caster due to loss of temperature.

When Insulating Powder (Radex) – Innsulekx is spread as coating over the molten metal (about 1 inch to 2 inches thick blanket on the hot molten metal) in the ladle and tundish, it acts as a very good insulator and the temperature does not come down quickly in the tundish and ladle.
