Fully Automatic Refractory Thermal Shock Resistance Tester
Published: 5/22/2019
Automated tester for evaluating the thermal shock resistance of refractory products and other non-metallic materials. Designed to comply with YB/T 376.1 and YB/T 2206.1-1998 test methods with optional compressed-air or water quench cooling modes.
Product Description
The RZL-II-14 is engineered to measure the thermal shock resistance of refractories, ceramics, glass, graphite, and silicate-based non-metallic materials. It is built to the requirements of YB/T 376.1 and also conforms to YB/T 2206.1-1998, ensuring standardized, repeatable testing.
A horizontally rotating sample chuck facilitates easy loading and direct observation of end-face damage during cyclic heating and quenching. The system integrates Siemens PLC automation with manual override, providing a graphical HMI on a 12-inch touchscreen for parameter setting, process control, and real-time data display.
The instrument supports two cooling approaches—compressed-air impingement and water quench—enabling users to match the method to their material and standard requirements. The compact, integrated design emphasizes ease of operation and minimal footprint, with clearly labeled, brand-name electrical components and comprehensive protection features including over-temperature, thermocouple break alarms, and emergency stop.
