Ceramic fiber castable
Ceramic fiber castable, this product is a kind of clay-like indeterminate refractory material, which is made of blown fiber cotton with low slag ball content as aggregate, with a certain proportion of binder, refractory filler and additives. It has the characteristics of low bulk density, low heat capacity, low thermal conductivity, high strength, and good air tightness. It is widely used in the lining of medium and low temperature thermal equipment and movable furnace covers. a good thermal insulation material. The product has good construction workability and strong integrity of the furnace wall after construction, and is especially suitable for wall linings with complex shapes.
