| Structure division | See affix |
| Weight | About 3200Kg |
| Overall Dimension | 13425×1200×1350mm(L×W×H),(Exclude mounting feet and alarm lamp) |
| Furnace Appearance | Outside panel uses high temperature spraying coating and off-white color |
| Rate Temperature | 1050ºC |
| Max Temperature | 1100ºC |
| Heating element | Heating wire around ceramic bar |
| Heating power | 72kW |
| Insulation Power of Empty Furnace: | ≤25kW |
| Zone Number | 9 zones |
| Temperature Control Point | 9 point |
| Thermocouple | K type, Watlow |
| Surface temperature rise | <35ºC |
| Discharging Temperature | ±1ºC |
| Temperature Control Stability | ±3ºC(Flat-Temperature zone) |
| Belt width | 350mm |
| Belt Material | SUS314 |
| Max Load on the Belt | 50Kg/m2(exclude the belt weight) |
| Drive Mode | Big wrap angle friction drive. |
| Belt Speed | 30~200mm/min, stepless speed regulation control with frequency conversion |
| Drive Control | 20~150mm/min,typical speed: 60~70mm/min, stepless speed regulation control with frequency conversion |
| Drive System | Drive Control uses the frequency converter drive frequency variable motor to control the speed by gear box. The speed is adjustable continually. |
| Belt cleaning mode | Ultrasonic cleaning |
| Firing Atmosphere | 7 pipes N2, the flowmeter range is 12~120L/Min; each pipe flow can be adjusted (See affix) |
| 2 pipe H2, the flowmeter range is 5~50L/Min; the flow can be adjusted (See affix). | |
| Oxygen content test | There are 6 points to connect with oxygen analyzer that are Entrance transition part,Pre-heating part, high temp part, Heating preservation and cooling zone,cooling zone, and exit transition part. Detect the oxygen content in real-time. |
| Automatic oxygen content test | Oxygen analyzer online analysis, through the solenoid valve switching |
| Oxygen content index | 10ppm+ oxygen content from gas source. |
| Exhaust System: | Entrance and exit Vestibule jacket have 1 exhaust pipe separately. |
| Cooling structure | Water cooling jacket (SUS304) |
| Cooling mode | Use gas cooling plus water cooling |
| Cooling detection | 1 water temperature test point |
| Alarm instructions: | Low water pressure alarm, over temperature alarm |
| Belt button | One emergency stop buttons at the entrance and exit of the furnace ( for stopping the belt) |
| Alarm instructions | Over temp, thermocouple failure, low gas pressure, audible and visual protection. |
| power failure protection | UPS protect the computer |
| Equipment safety heating rate | ≤2ºC/min |
| Temperature Measuring: | Use K type thermocouple independent measuring and control on the temperature control point of each zone. |
| Control instrument | Use of intelligent temperature controller to control, with PID parameter auto tuning, high temperature upper limit alarm, thermocouple failure and other protective alarm functions. |
| Control Mode | Solid State relay zero cross trigger mode. |
| Over Temperature Alarm: | When over temperature occurred in some zones, over temperature alarm system in corresponding zones immediately send audible and visual alarm signal and meanwhile the heating of this zone is cut off, the buzzer sounds alarm |
| Computer Control System | Use DCS control system |
| SIEMENS PLC control, upper industrial control computer monitoring | |
| Industrial computer can carry out multiple programs saving | |
| Real-time temperature and alarm record,data saving and printing. | |
| The computer control system has a function of slope temperature rise, prolong the service life of the muffle tube | |
| It also can provide the temperature calibration function in the chamber for adjusting process requirement. | |
| Reserve the internet access for remote reading data |
