ActiveRefractory products—Determination of 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 refractoriness of refractory products, measuring the temperature at which a test cone deforms under specific heating conditions. It is applied in the quality control and material classification of refractory materials used in high-temperature industrial furnaces, such as those in the steel, cement, and glass industries. The standard ensures that refractory products meet thermal performance requirements for their intended application environments.
