GB/T 4513.8 - 2017 is the eighth part of the standard for amorphous refractories, focusing on special performance measurement. This part covers special performance testing methods such as abrasion resistance and thermal shock resistance. It specifies various types of equipment required for performance measurement, standardizes sample preparation and testing procedures, such as abrasion resistance testing needs to simulate the actual abrasion environment. Through these tests, the comprehensive performance of amorphous refractories under complex high temperature conditions can be fully evaluated, providing a basis for manufacturers to optimize product formulations and users to accurately select suitable materials, and helping to improve the operation Stability and life of industrial high temperature facilities.
