Note: This is a variation of Dense Castables.
Foundry Service sells only high quality, pure, high density castables (monolithic)suitable for high temperature structural applications. These dense castables are available in various grades suitable for a specific range of operational conditions. Our refractory castables are hydraulic setting and can be casted or molded to any shape. All of these castables can also be modified for gunning applications. Foundry Service can pre-cast and fire parts and shapes per customer suppliecell namerawings as well.
