Low Cement Castable

FurnaCubed 70QT

FURNACUBED™ 70 is a 74% alumina, non-wetting to aluminum, low cement castable that can be heated without using the traditional ramp-and-hold heatup schedule. It can be vibration cast, self-flow cast, or shotcreted. This product has excellent thermal shock resistance to 2000ºF. It has been used for preformed blocks in an aluminum furnace and has been shotcreted in aluminum furnace upper and lower walls. Unlike other FURNACUBED™ products, this product is recommended for use only in aluminum furnace applications. Therefore, its maximum non-metal contact use temperature is 2500ºF.
