Silplate Structural Insulating Board
Silplate® boards were specially developed by Unifrax for backup applications that require a very high-strength refractory insulating material. Common applications are for backup in ladles or tundishes that are used in molten metal transfer. Using Silplate boards for backup applications can significantly reduce steel shell cold face temperatures. Because of Silplate’s high use temperature limit, in many cases a thinner refractory cross section may be used and this practice results in increased vessel capacity.
