High Temperature Hydrogen Furnace, 1700℃ Hydrogen Gas Controlled Furnace
Hydrogen atmosphere furnace is specially designed for sintering or annealing materials in hydrogen or inert gas environment. The highest temperature can reach to 1600℃. Alumina fiber is used as a furnace chamber material and Mo wire is used as the heating element. The cooling water pipe is embedded in the sealing plate at the top of the furnace body to ensure the sealing performance during working.
This electric hydrogen box furnace is suitable for materials (such as fluorescent materials, titanium alloys, etc.) that need to be sintered in the environment of inert gas or reducing atmosphere.
Hydrogen Furnace Features
- The working temperature can be adjusted at 0 ℃ ~ 1600 ℃.
- Heating element: High purity molybdenum wire (molybdenum content 99.99%)
- Double-layer shell structure with air-cooling and water-cooling system to maintain the positive internal pressure of 0.02MP and negative pressure up to -0.1MP.
- Build a pressure sensor and a pressure controller. According to the set pressure limit, control the inlet and outlet valves to protect the high and low pressure.
- Hydrogen Furnace body is equipped with two large-flow flowmeters (N2: 0~3.5L / min, H2: 0~3.5L / min) float flowmeter, which can freely control the gas flow.
- Hydrogen Furnace H2 safety device: H2 tail gas is automatically ignited and burned. The flame detector will automatically ignite when the flame is extinguished. The H2 is automatically cut off when the ignition fails and then filling N2 for security.
