Door sealing materialIt is ceramic fiber rope and gasket. No need cooling water.
Air circulation system
Mode of air circulationAir from bottom to up, forcing hot air circulation.
Air outlet positionFrom bottom of oven side
Air output amount controlUsing double air baffle (with holes) to control air outlet amount. To ensure temperature evenness.
Air input amount controlAt oven ceiling, using baffle (with holes) to control, ensure temperature evenness in oven.
BlowerUsing hot air blower, no need cooling water.
Heating System
Heating elementsAdopted star-connection; U-shape heating element
Location of heating elementIt is located on both sides of oven.
Oven body thermal insulation
Thickness of insulation160-200mm
Insulation materialHigh-grade aluminum silicate cotton is used. Temperature conducting coefficient is 0.048Kcal/mhºC.
Electrical system
Control cabinetAn independent control cabinet at side of oven. 
With main-air-switch in cabinet; with time-relay.
Main temp.controlUsing Xiamen Yuguang AI-518P program with PID digital displayer temperature controller. With RCR computer communication joint, with K-type thermal couple.
Over-temp. alarmUsing Xiamen Yuguang AI508 digital alarm, with K-type thermal couple.
K-type thermal couple socketWith 6 piece of socket on control cabinet for thermal couple connection.
DC power supplyWith SMER-WZY power supply, current is 2000A.
N2 input controlN2 input is controlled by solenoid valve. Input time is controlled by time-relay. With a LZB-4 flow meter.
Safety protectElectricity leak protection: to protect operator.
Over-temp.alarm: when oven inside temp. is abnormal, alarm rings and heating is stopped automatically.
Motor and heating is inter-lock. First blowing, then heating. To avoid heating element damaged.
Control protectionMotor over-current protection, avoid motor damaged.
Heater over-current protection, avoid heater short-circuit.
Temperature over protection (heater will stop when temperature over).
Breaker, avoid main circuit over loading.
Oven accessories
N2 inputBuyer provide N2 gas source.
With 2 input pipes (DN25mm). It is installed on top of annealing oven. One pipe insert into air channel, close to blower fan. The other input to furnace.
On the two sides-buttom of furnace, there is 50mm gas-ventilation holes. With cover plate (adjustable).
