No. | Name | Description |
A | Entrance curtains | Prevent outside air from entering the furnace |
B | Burn off gas inlet | Used for gas supplement of heating zone |
C | Exhaust gas inlet | The manual valve on Venturi exhaust tube can be used for adjusting gas flow |
D | Firing gas inlet | Used for control gas flow direction and prevent colloid pollution the products |
E | Exit curtains | Prevent outside air from entering the furnace |
The actual gas flow of each pipe can be displayed by flowmeters. |
Cooling structure | Stainless steel cooling water jacket, there is cooling fan at the exit table. |
Emergency Stop Button | two emergency stop buttons at the entrance and exit of the furnace, one for belt and one for power |
Alarm instructions | over temperature, thermocouple failure, low gas pressure,low water pressure, low water pressure, belt stop alarm, ignitor alarm and other audible and visual protection |
Temperature measuring | use K type thermocouple independent measuring and control on the temperature control point of each zone |
Temperature control | use of imported 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, |
Intelligent temperature controller control, industrial computer monitor | |
Friendly human-machine interface, industrial computer can carry out multiple programs saving | |
Real-time temperature and alarm record, data saving and printing. | |
It also can provide the temperature calibration function in the chamber for adjusting process requirement. |
