The automatic air-cooled thermal shock furnace (thermal shock test furnace) is a high-precision device used to evaluate the thermal shock resistance of materials. It simulates extreme temperature changes through rapid heating and cooling, and is widely applied in various fields such as ceramics, refractory materials, and metals. It can accurately test the crack resistance, fatigue life, and structural stability of materials under thermal shock, providing key basis for material research and development as well as quality control.
Automatic air-cooled thermal shock furnace (also known as thermal shock test furnace) is a high-precision equipment used for testing the thermal shock performance of materials. It is widely applied in fields such as ceramics, refractory materials, metals, coatings, and composite materials. By simulating extreme temperature change environments through rapid heating and cooling, this equipment evaluates the crack resistance, fatigue life, and structural stability of materials under thermal shock conditions.

| Heating Rate | Freely adjustable, maximum heating rate 20℃/min |
| Heating Elements | Silicon carbide rods |
| Furnace Body | Processed by CNC machine tools, through polishing, grinding, pickling, phosphating, plastic powder spraying, and high-temperature baking. It adopts a two-color design with a novel and beautiful appearance, and has advantages such as oxidation resistance, acid and alkali resistance, corrosion resistance, high-temperature resistance, and easy cleaning. |
| Refractory Materials | The furnace lining is made of vacuum-formed high-purity alumina lightweight materials |
| Insulation Materials | Three-layer insulation: aluminosilicate fiberboard, alumina fiberboard, and alumina (polycrystalline) fiberboard. The energy-saving effect is over 80% compared with old-style electric furnaces. |
| Furnace Shell Temperature | ≤45℃ during long-term continuous operation |
| Protection | Adopts integrated module control unit with accurate control precision, designed with dual-loop control and protection, featuring overshoot, undershoot, thermocouple break, phase loss, overvoltage, overcurrent, overtemperature, current feedback, and soft start protection. |
| Control Method | Uses closed-loop thyristor module trigger control (phase-shift trigger mode). Output voltage, current, or power is continuously adjustable with constant voltage, current, or power characteristics. The current loop is the inner loop and the voltage loop is the outer loop. When the load is suddenly applied or exceeds the current limit, the output current is limited within the rated range to protect heating elements from excessive current/voltage impact, ensuring safe and reliable control effect and precision. |
