ActiveRefractories—Determination of thermal expansion
耐火材料 热膨胀试验方法
Application Summary AI generated
This standard specifies the test method for determining the thermal expansion of refractory materials, including linear expansion and expansion rate. It is applied in the quality control and performance evaluation of refractories used in high-temperature industrial furnaces, such as in the steel, cement, and glass industries. The standard ensures materials can withstand thermal stress during heating and cooling cycles.
