RR White Heat C
RR white heat range of conventions castable are scientifically designed ready mixed castable made from recon refractory best bond a high purity calcium aluminate binder and selected hard burnt grade refractory bauxite.
RR white heat castable are hydraulic setting and can be in-site cast or molded to any shape and also mixed for gunning of furnace lining.
The water content for rodding or vibrating should be 10 to 15 percent by weight of castable to obtain workable consistency.
