Description
1600°C High-Temperature Hydrogen Furnace
The high-temperature hydrogen furnace is an industrial-grade furnace designed for high-temperature atmosphere reduction, heat treatment, and special material experiments. Based on a two-layer steel structure furnace body, the equipment incorporates water-cooled sealing, a track-guided lifting mechanism, and a modular electrical control system upgrade, enabling stable operation in high-temperature hydrogen/inert atmosphere environments. It utilizes tungsten-rhenium thermocouple temperature measurement and a dual-zone temperature control structure, coupled with a multi-transformer power supply system and SCR power regulation control, to achieve stable high-power output. The system supports centralized control via PLC and touchscreen, and features oxygen content monitoring, exhaust ignition protection, and multiple safety interlocking mechanisms, making it suitable for high-end scientific research and industrial heat treatment scenarios.
Product Features
- Dedicated for Hydrogen Atmosphere, Equipped with Ignition Device
This equipment is specifically designed for high-temperature heat treatment processes in a hydrogen atmosphere. The exhaust port is equipped with a solenoid valve and ignition device to ignite unreacted hydrogen at the exhaust port, effectively preventing the risk of explosion due to hydrogen accumulation indoors. Two inlet valves and two flow meters (D22) ensure precise hydrogen flow control.
- Three Transformers with Independent Power Supply, Total Power 270kW
Equipped with three transformers, each 90kW, totaling 270kW. This allows for independent power supply and distribution to different zones, with flexible adjustment of heating power.
- Dual Protection with Yudian Temperature Controllers and Over-Temperature Alarms
Two sets of Yudian temperature controllers (top and bottom) provide independent temperature control. Two independent over-temperature alarms provide dual temperature protection. Automatic temperature switching uses Siemens chips for precise and reliable temperature control.
- Tungsten/Molybdenum Rod Heating Element, Excellent Ultra-High Temperature Performance
The heating element uses tungsten/molybdenum rods, installed on the left, right, and bottom to form a three-dimensional heating field. Tungsten and molybdenum materials have extremely high melting points and high-temperature strength, suitable for long-term stable operation in a hydrogen atmosphere at 1600℃.
- Lifting Furnace Door + Top Water-Cooled Seal
The furnace door uses a lifting mechanism controlled by a motor, reducer, and frequency converter, with positioning and locking at the lifting position. The top uses a water-cooled sealing structure, effectively reducing the temperature of the seals and extending their service life.
- Siemens PLC + 10-inch Touchscreen Centralized Control
Centralized control is achieved using a Siemens S7-200 PLC and a 10-inch touchscreen. Software programming enables fully automatic heating, heat preservation, and cooling. The IP54 protection-rated control cabinet is suitable for industrial environments.
- Real-time Oxygen Content Sensor Monitoring
Equipped with an oxygen content sensor (Shanghai), it monitors the oxygen concentration inside the furnace in real time, ensuring process safety in a hydrogen atmosphere.
