Description

ZIRCAR Ceramics’ Alumina-Silica Type RNKO is a combination of low-shot refractory ceramic fibers (RCF) and inorganic refractory binders. RNKO’s uniformly distributed binders work to create a structure that exhibits low thermal conductivity and at the same time gives RNKO high compressive strength and exceptional machinabilty. These unique properties combine to make RNKO a product of choice for the fabrication of baffles, side dams and other structural components built into hard, ceramic-fiber-based castertips and caster nozzle assemblies. RNKO can also be a very effective backup thermal insulation layer in conventionally bricked or cast refractory systems.
RNKO is 100% inorganic, does not outgas and is readily coated with non-wetting release agents such as Boron Nitride or Alumina-Silica mortars and Alumina Cements.
RNKO is free of organic binders and will produce no smoke or odors when heated. It has excellent resistance to chemical attack and is not affected by oil or water. It is, however, affected by hydrofluoric acid, phosphoric acid and strong alkalis.
