    Specific Introduction:
        KJ-1700X-S60 tube furnace is a small-scale tube furnace that has passed CE certification. The heating and cooling are controlled by 30-segment programmable intelligent meters. The furnace tube size is 60mm (OD) × 50mm (ID) × 800 (L )mm. This high-temperature furnace can be widely used for sintering or annealing of materials (under vacuum or inert gas protection).
    The main parameters
    • · Maximum temperature: 1650 ℃ (<2h) (update: 19.12.10 - JS2)
    • ·Long-term working temperature: 800-1600℃
    • ·Recommended heating rate: below 1400℃: ≤10℃/min; 1400℃ to 1600℃: ≤5℃/min; after 1600℃: ≤2℃/min
    • ·Length of heating zone: 170mm
    • ·Maximum power: 2.5 KW
    • ·Voltage: Single-phase AC220V 50Hz (30A air switch required)
    Furnace structure
    • ·The furnace uses high-purity polycrystalline alumina fiber to minimize energy loss
    • ·The surface of the inner furnace is coated with 1750 degrees high temperature alumina coating imported from the United States, which can improve the reflectivity and heating efficiency of the equipment, and also extend the service life of the instrument
    Furnace tube
    • ·(Standard configuration) OD: 60 mm x 800 mm L
    • ·In order to ensure the uniformity of the temperature field and the tightness of the flange, it is necessary to plug alumina pipe plugs at both ends of the furnace tube before heating the instrument to prevent heat loss
    Vacuum sealed
    • ·Standard equipped with two stainless steel vacuum flanges (mechanical pressure gauge and stainless steel globe valve have been installed on it)
    • ·Optional: In order to obtain a higher vacuum degree faster, it is recommended to use KF25 stainless steel flange (as shown below), stainless steel bellows and digital vacuum indicator
    Flange interface
    • ·In order to get a better vacuum state, you can choose KF25 adapter to connect with bellows on the outlet flange
    • ·A variety of joints are available, please ask our sales department for details
    • ·The vacuum degree of double rotary vane mechanical pump can reach 10-3 torr (reference value)
    • ·If you want to get a higher vacuum degree (<10-5 torr or better), domestic or imported high vacuum unit can be selected (reference value)
    • The anti-corrosion digital vacuum indicator imported by our company has a measuring range of 3.8x105 to 1125 Torr. There is no need for coefficient conversion due to different types of measuring gases
    Temperature Control System
    • ·Contains a YD518P temperature controller
    • ·PID automatic temperature control system
    • ·Intelligent 30-segment programmable control
    • ·Temperature control accuracy: ±1℃
    • ·Default DB9 PC communication connection port
    • ·Passed MET certification
    • ·Computer temperature control software (for YD518P series controller) can be purchased to control the heating curve and export data.
    Heating element
    • 1800ºC grade silicon molybdenum rod
    • Furnace size: 1150 L×450 W×650 H mm
    • Furnace size: 170×130×120
    Net weight
    • 150 Kg
    • One year warranty and lifetime technical support.
    • Special tips: 1. Consumable parts such as heating elements, quartz tubes, sample crucibles, etc. are not included. 2. Damage caused by the use of corrosive and acid gases is not covered by the warranty
    Application note
    • ·The air pressure in the furnace tube cannot be higher than 0.02MPa
    • ·Because the internal pressure of the gas cylinder is relatively high, a pressure reducing valve must be installed on the gas cylinder when the gas is fed into the furnace tube. It is recommended to purchase a pressure reducing valve from our company. The range of our company's pressure reducing valve is 0.01MPa-0.1MPa. It will be more precise and safe to use
    • ·For the sample heating experiment, it is not recommended to close the exhaust valve and intake valve at the flange end of the furnace tube. If you need to close the gas valve to heat the sample, you should always pay attention to the indication of the pressure gauge. If the indication of the air pressure is greater than 0.02MPa, you must open the vent valve immediately to prevent accidents (such as furnace tube rupture, flange flying, etc.)
    • ·The flow of gas should be limited to <200 SCCM (or 200ml/min)
