RZL-14 Thermal Shock Resistance Testing Machine

Rzl- 14Thermal shock resistancetesting machine

RZL-14 Thermal Shock Resistance Testing MachineUsed to determine the thermal shock resistance of refractory products, manufactured in accordance with the requirements of YB/T 376.1 "Test Method for Thermal Shock Resistance of Refractory Products" for 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.

​

Maintenance and Precautions

1. When the electric furnace is used for * times or when it is used again after * shutdown, it must be dried in an oven. Slow heating can achieve the purpose of drying the oven.

2. When using an electric furnace, the furnace temperature should not exceed the rated temperature to avoid damaging the heating elements. The furnace should be regularly cleaned of iron filings, oxides, etc.

3. Regularly check whether the contact at each connection line of the electric furnace is good.

4. The instrument should be kept clean, tidy, and regularly oiled to prevent rusting of the mechanical parts of the equipment.
