Permanent Layer Castable Refractory for Tundish

Permanent Layer Castable Refractory for Tundish. Permanent Layer Castable Refractory for Tundish is formulated with high-alumina hard aggregates, refractory fine powder and composite binders. It features good thermal insulation, high temperature resistance and superior strength, and is cost-effective and durable. This product is specially used as the base lining between the tundish shell and working layer. This tundish permanent layer castable is applicable to the permanent thermal insulation lining on the wall and bottom of continuous casting tundishes, as well as integral base casting for tundishes. It features low thermal conductivity and excellent heat preservation, effectively reducing heat loss of molten steel. With superior high-temperature resistance and good thermal stability, it will not loosen or pulverize during long-term service. The material boasts strong adhesion and tight bonding with the steel she. It also has excellent thermal shock resistance, resisting cracking and peeling under drastic temperature changes. It can firmly support the working layer, extend the service life of the overall lining, and greatly cut construction and material costs.
