Application Summary AI generated
This standard specifies the classification method for basic dense shaped refractory products that contain between 7% and 50% residual carbon. It is applied in the manufacturing and quality control of refractory materials used in high-temperature industrial furnaces, such as those in steelmaking, cement, and glass production. The classification helps engineers and procurement professionals select appropriate refractory products based on their carbon content and performance requirements.
