    Specific Introduction:
        KJ-1600X-R-II is a high temperature double temperature zone rotary furnace. This equipment is specially designed to sinter the powder uniformly at high temperature.
    Furnace Construction
    • Double shell casing with three cooling fans
    • High purity Alumina fibrous insulation for max. energy saving
    • Dual heating zone with 1600ºC max. continuous working temperature
    • Electric motor to drive the tube at variable speed
    Heating Zone length
    Max. Working Temperature
    • Two zones heated separately
      • Zone 1: working temperature  800 - 1700ºC (heated by MoSi2)
      • Zone 2: working temperature  800 - 1700ºC
    • Constant temperature zone length: 10" (250mm) within +/-1
    • Max. Heating rate: 10 oC/minute
    Processing tube & Sealing Flange
    • 99.8% purity Alumina Tube
    • 60 mm stainless steel vacuum sealing flange with valve and meter is included
    • One ceramic block is installed on each side flange to block thermal radiation during rotation
    • 2-3/8" (60mm) O.D. x 2-1/8" (54mm) I.D x 48" (1200 mm)  Length with inside block
    Gas Fittings Inlet Fitting: Elbow Push-in connector for 6mm O.D tube; Outlet Fitting:  Elbow Push-in connector for 12mm O.D tube
    Temperature Controller
    • Two 30 segments programmable PID digital temperature controller 
    • Note: To achieve fully temperature computerization please order a set of MTS-02 control modules. If you order the control module with the furnace we will install and test it before we ship out the product. We recommend you order a computer (laptop) from us.

    • The tube furnaces with alumina tube are designed for use under vacuum and low pressure < 0.02 MPa / 0.2 Bar/ 3 PSI 
    • Attention: A two-stage pressure regulator must be installed on a gas cylinder to limit the pressure to below 3 PSI for safe operation.
    • Never heat the furnace while the gas release valve is closed and a positive pressure condition exists within the furnace chamber. The pressure gauge must be used to closely monitor the chamber condition at all times during the heating process; please open the gas release valve immediately once the chamber pressure has reached over 3 PSI to prevent unforeseeable damages.
    • The flow rate for gases should be limited to < 200 SCCM ( or 200ml/min )
    • limit definition for all alumina tube furnaces: * Vacuum pressures may only be safely used up to 1500°C
