| Usage | Atmosphere furnace is designed for material synthesis under controlled inert gas atmosphere or mixture gases with better temperature uniformity. It is an ideal heating equipment for preparing new material which requires inert gas or oxidizing gas including hydrogen gas. | |||
| Furnace structure | 1. The furnace is consist of heating system, gas system, vacuum system 2. chamber is consist of insulation material and heating elements and atmosphere boxes 3. Temperature controller is consist of PID temp. controller, control elements and thermocouple 4. Integrated the furnace body and the temperature controller in one, the furnace is fixed on the temperature controller | |||
| Max. Working temperature | Air, Nitrogen Dioxide (NO2), Carbon Dioxide (CO2): 1700C degree Helium (He), Neon (Ne), Argon (Ar): 1650C degree Nitrogen (N2), Carbon Monoxide (CO), Hydrogen (H2) up to 5%:1600C degree Rough vacuum 1500°C | |||
| Heating Rate | ≤10ºC/min (suggest 8ºC/min for longer life using of furnace) | |||
| Heating Element | 1.High quality Molybdenum silicide rods (MoSi2, diameter 6X12mm) 2.High quality vacuum formed insulation ensure fast heat up, excellent temperature control and short cool down times 3.Vertical layout, distribute in two sides evenly, give an improved temperature gradient (each side 4 pcs, total 8 sets) 4.U shape non-metal high temperature heating element with high purity Mo and SI as main material. Fast rising speed and long service life. Easy for installing and replacement, max temperature can reach 1700°C | |||
| Chamber material | 1. Adopt high quality alumina polycrystalline fiber, which used Japanese technology (vac-sorb forming alumina polycrystalline fiber) with good insulation and durability properties 2. High quality 1800 degree fiber alumina as refractory lining, pure white color 3. Ceramic fiber insulation for fast heat-up and reduced energy consumption 4. Vertical layout of heating elements on the round chamber which give an ideal temperature uniformity | |||
| Temp. Uniformity | ±5°C | |||
| Thermocouple | type B | |||
| Temperature Controller | 1. Control system integrated in the furnace base, Defined application within the constraints of the operating instructions 2. Furnace temperature controller utilizes Intelligent PID 30 segments program 3. Feature single setpoint digital control, LED display of actual temperature VS set point 4. A high-precision digital microprocessor controller fitted with self-tuning and manual PID settings makes temperature and other parameters easy to control 5. Temperature controller Precision ±1ºC | |||
| Atmosphere perfermance | high temperature PTFE gasket is installed on the furnace door to ensure the reliable sealing of the furnace; Ultimate vacuum level for STQ furnaces is around 20000Pa with hose barb connections. Please keep in mind that our STQ series of atmosphere furnaces are NOT designed to be vacuum furnaces, the vacuuming part is mainly for users to pre-vacuum the chamber, before putting in inert or other protective gases. | |||
| inlet port and outlet | 1.The inlet and outlet ports are designed on the side and back wall of the furnace body and can be supplied with inert protective gas. The gas flow rate is controlled by a float flowmeter with a range of 1-10L/min. 2.Two ports on the back of the wall will make it accessible to water cooling. | |||
| Electronic component | air switch, buttons, solid-state relay, A.C contactor etc. | |||
| Furnace Shell | 1. High quality cold-rolled steel sheets CNC processing 2. Environmental electrostatic plastic-spraying on surface after deoiling, derusting, phosphating etc. nine processes 3. Energy efficient insulation keeps exterior safe to touch | |||
| Safety Precautions | 1. Overheating & Broken thermocouple protection 2. Leakage circuit breaker 3. Automatic power off when furnace door opens (optional function) 4. Over-temperature protection and alarm allow for operation without attendant(s) 5. Microprocessor-based PID control with self-tuning capability to prevent overshooting of set temperature | |||
| Optional Accessories | 1. Vacuum Gauge 2. Vacuum pump 3. Industrial chiller (to cool the furnace body during heat processing for safe and prolonged lifetime) 4. Mass flowmeter 5. Corumdum crucibles 6. Exhaust chimney | |||
| Certification | ISO9001 CE | |||
| Warranty | One year limited manufacturer's warranty (Consumable parts such as processing tubes, O-rings and heating elements are not covered by the warranty, please order replacements at related products respectively | |||
