OTF-1200X-VTQ-HG Vertical Hydrogen Tube Furnace with 4″ Stainless Steel Tube and Liquid Quenching Tank
The OTF-1200X-VTQ-HG is engineered for advanced material research requiring rapid thermal quenching from elevated temperatures. This vertical hydrogen tube furnace incorporates a vacuum-sealed stainless steel tube with a 101 mm outer diameter and 92 mm inner diameter, providing a controlled environment for heat treatment up to 1000°C. The design supports studies of phase transitions and microstructural changes by enabling samples to be swiftly quenched into ice water or oil.
The furnace features a split vertical structure with double-layer steel casing and air cooling to maintain external temperatures below 65°C. A liquid quenching tank is connected via a 4″ quartz tube and a manual gate valve, allowing automatic sample release through an electromagnet-controlled flange. This setup ensures precise and repeatable quenching processes while minimizing cable wear compared to traditional cable-cut methods.
Wichtigste Merkmale

Typische Anwendungsbereiche
This furnace is ideal for metallurgical and materials science research involving phase transition analysis, microstructural studies, and heat treatment processes requiring rapid quenching under controlled hydrogen atmospheres. It supports experiments that demand precise temperature profiles and safe handling of flammable gases.
Hinweise zur Konfiguration und zum Betrieb
The system includes an automatic electromagnet sample release flange and a manual gate valve connecting the tube to the quenching tank. Users must employ ice water or cooled oil as quenching media, especially under vacuum conditions. Optional gas purification and hermetic quenching tanks are available for enhanced atmosphere control. Safety features include hydrogen detection with automatic shutoff and over-temperature alarms. Proper installation of a two-stage pressure regulator on hydrogen gas cylinders is required to maintain safe operating pressures below 3 PSI.
