GB/T 7322-2007
AbolishedRefractory products - Determination of pyrometric cone equivalent (refractoriness)
耐火材料 耐火度试验方法
Application Summary AI generated
This standard specifies the test method for determining the pyrometric cone equivalent (refractoriness) of refractory materials. It is applied in the manufacturing and quality control of refractory products, such as firebricks and ceramic fibers, used in high-temperature industrial furnaces, kilns, and incinerators. The standard ensures materials can withstand specific thermal loads without deformation or melting, critical for industries like steelmaking, glass production, and cement manufacturing.
