GB/T 18931-2002
AbolishedClassification of basic refractory products containing less than 7% residual carbon
残炭含量小于7%的碱性耐火制品分类
Application Summary AI generated
This standard specifies the classification criteria for basic refractory products with residual carbon content below 7%, categorizing them based on chemical composition and physical properties. It is applied in the manufacturing and quality control of refractory materials used in high-temperature industrial furnaces, such as those in steelmaking, cement kilns, and glass melting tanks. The standard ensures consistent product grading for procurement and engineering specifications in the refractory industry.
