1500 ℃ open type single-zone tube furnace adopts silicon carbide rod as heating element, providing a rated temperature of 1,400 ℃ and a maximum temperature of 1,500 ℃. With Yudian AI-3756P touch screen type temperature controller and S-type thermocouple, temperature control through 30 programmable segments with a temperature control precision of ±1 ℃ is realized. With a set of 316 L stainless steel open-quick flanges that adopt double-ring sealing technology, the equipment can be applied to various experiment environments such as sintering and substrate coating in vacuum or atmosphere. The built-in double-layer air cooling structure provides a surface temperature ≤60 ℃. Both ends of the flanges are supported to lighten the load of the furnace tube, thereby guaranteeing the service life of the furnace tube.
