Refractory material thermal shock testing machine

Rzl- 14 / 16Thermal shock resistance of refractory materialstesting machine

The refractory material thermal shock testing machine is used to determine the thermal shock resistance of refractory products, and is manufactured in accordance with the requirements of YB/T 376.1 "Test Method for Thermal Shock Resistance of Refractory Products" for the equipment. The sample clamp can rotate horizontally to facilitate the observation of sample end face damage during loading. The instrument also meets the requirements of YB/T2206.1-1998 Test Method for Thermal Shock Resistance of Refractory Products. This instrument is suitable for conducting thermal shock resistance tests on refractory products, ceramics, glass and other non-metallic materials, graphite materials, and silicate products.
