GB/T 2 2459.7 - 2008 standard focuses on the test method of high temperature performance of refractory slurry. It specifies the test process for the performance of refractory slurry under high temperature environment, such as load softening temperature, high temperature flexural strength, thermal shock Stability, etc., including test equipment selection, heating system, Sample Handling and data measurement. High temperature performance is directly related to the actual application effect of refractory slurry in high temperature facilities such as industrial kilns. The standard provides testing basis for production enterprises and testing institutions to help ensure that refractory slurry maintains good performance under high temperature conditions and ensures stable operation of high temperature facilities.
