Service specifics of refractory lining in a float tank and tests of new heat-resistant composite materials

To avoid glass defects as a consequence of lining destruction in service and to preserve the operating conditions of a float tank equipment, it is necessary to use high-quality refractory materials which are developed taking into account their service specifics. Researchers at the Saratov Institute of Glass have identified maximum admissible fluctuation parameters for the gaseous atmosphere composition in the metal tank, which influences the destruction of refractory lining. New types of composites, namely, concretes on a refractory chamotte basis produced at the Semiluki Refractory Works, have been tested in the service conditions.
