Technical description from the published product record
I. Equipment Overview The hydrogen reduction tube furnace is a special atmosphere heat treatment equipment. It takes the sealed tube cavity as the core, supports vacuum displacement + hydrogen/inert mixed atmosphere, uses strong hydrogen reduction to remove the material oxide layer at high temperatures, and is equipped with a complete explosion-proof, airtight, and temperature control system. It is mostly used in university laboratories, magnetic materials, powder metallurgy, and electronic powder reduction and sintering. Second, the core technical parameters (refer to the QLJZ series supporting tube models) temperature system is 1200 ℃ high, long-term stable use ≤ 1100 ℃; three-sided resistance wire surround heating, K-type thermocouple, temperature control accuracy ± 1 ℃; heating rate 1 ~ 20 ℃/min adjustable, recommended 1 ~ 10 ℃/min; 30 PID programmable temperature control, thyristor automatic adjustment. Furnace tube and cavity quartz/stainless steel sealed furnace tube, flanged high-temperature silicone seal; double-layer water-cooled furnace door, double-layer air-cooled shell of the whole machine, shell temperature ≤ 60 ℃. The vacuum path can be pre-vacuumed to - 0.08 MPa; hydrogen, nitrogen and argon can be introduced; an independent precision float flow meter is provided to maintain a micro positive pressure (< 0.02 MPa) in the furnace to prevent air backfilling of the oxidized sample; the oxygen content can be reduced by multiple vacuum displacements. Power supply power 380V, regular power 12kW, support multi-dimension furnace tube customization. 3. Whole machine structure heating furnace: high-purity alumina fiber splicing furnace,
Good thermal insulation, low heat storage, fast heating and cooling; sealed tube cavity: front and rear flange water-cooled sealing structure, strong air tightness, suitable for flammable and explosive hydrogen working conditions; special hydrogen atmosphere road: independent intake, exhaust, vacuum three pipelines, stainless steel valves, exhaust gas centralized discharge; cooling system: furnace door water-cooling + furnace body double-layer air-cooling double heat dissipation; intelligent electronic control: touch screen program control, with over-temperature, water pressure, air leakage, overflow acousto-optic interlock protection. Fourth, the core characteristics of deep reduction Deoxidation of high-temperature hydrogen can reduce the surface oxides of metals and powders to obtain high-purity non-oxidation samples, which are suitable for magnetic/rare metal powders such as neodymium iron boron, tungsten molybdenum, and nickel cobalt. The vacuum displacement washing furnace process can repeatedly pump vacuum filling protection gas, quickly reduce the oxygen content in the furnace, avoid the hidden danger of hydrogen and air mixing, and the process is stable. The complete hydrogen design furnace isolates the air under micro-positive pressure throughout the whole process; the water-cooled seal eliminates high-temperature leakage; the automatic shutdown interlocks with over-temperature, water cut-off, and abnormal air pressure, and the explosion-proof protection is perfect. The automatic process runs 30 stages of heating, insulation, reduction, and cooling curves for one-click storage. The entire reduction process is unattended, and the experiment is highly repeatable. Energy-saving, durable, easy-to-maintain lightweight fiber insulation, fast heating and cooling; easy disassembly and assembly of furnace tubes and seals, standard operating procedures for oven drying and washing. 5. Scope of application Magnetic materials: neodymium ferroboron magnetic powder, ferrite hydrogen reduction sintering;
Powder metallurgy: Tungsten, molybdenum, nickel, cobalt and other metal oxides are reduced to high-purity metal powders; new energy/catalyst: precursor reduction, catalyst activation, lithium battery powder heat treatment; scientific research experiments: CVD, atmospheric annealing, high-purity sintering of metal ceramics, oxide deoxygenation and purification. Sixth, the use of matching and after-sales factory equipped with high-temperature gloves, crucible pliers, a full set of operating manuals; the whole machine warranty of one year, heating wire, thermocouple, sealing ring and other consumables are not covered by the warranty, the manufacturer provides oven, hydrogen operation training.
