Silica-Based Rice Husk Ladle/Tundish Covering Compound

This product is a silica-based ladle cover compound made from rice husk, specifically formulated for use in metallurgical applications. It boasts a silica content (SiO2) of at least 85%, making it ideal for high-temperature applications. The composition includes aluminum oxide (Al2O3) with a maximum of 5%, calcium oxide (CaO) at a maximum of 0.5%, magnesium oxide (MgO) not exceeding 1.0%, and iron oxide (Fe2O3) limited to 0.5%. The product has a moisture content of no more than 1% and a loss on ignition (LOI) maximum of 7%. The grain size specified is between 0mm, indicating a fine particulate form that enhances its coverage and insulation properties when applied. This formulation is preferable in metal casting, optimizing performance in the ladle process by providing effective thermal insulation and protecting the metal from oxidation.
