3 Terms and Definitions

The following terms and definitions defined in GB/T 18930 apply to this document. 3.1 pressure creep creepincompression The isothermal deformation of a refractory material over time under a constant load. 3.2 The temperature at which the creep rate of the specimen under load equals the expansion rate during the heating process.

4 principles

A sample of a given size is heated at a certain heating rate under a constant load and reaches the set temperature, and the temperature of the sample is recorded at a constant temperature. The amount of deformation in the height direction at temperature and the percentage change relative to the original height of the specimen over time. Note. The difference between the percentage change of the first 5h and the percentage change at the end of the test is usually recorded. ......
