Delivery method
1. Use Teflon mesh 0*0 air-permeable transmission network.
2. There is an automatic adjustment mechanism for grid deviation and limit protection
3. Adopt the frequency converter to freely adjust the speed without step, the speed range is 0.5~3 m/min.
4. High-grade fully enclosed gear reducer motor drive.

Structure distribution
1. The total length of the furnace body is 36000mm.
2. Feeding section 2500mm
3. Heating section 30000mm (Equally divided into 30 temperature zones, each temperature zone is 1000mm)
4. Cooling section 1000mm
5. Discharge section 2500mm

way to heat up
1. The heating section is 30 meters in total. Infrared irradiated electric heating and fin-shaped hot-air electric heaters can be heated by hot air, which can individually control the output of infrared and hot air systems.
2. Adopt PID temperature controller, with SCR component phase output control, fast temperature control speed and high stability.
3. The surface temperature of commonly used materials is 150℃, and the temperature uniformity of the material surface is within +/-1.5% across the left, middle and right.
4. The set temperature in the furnace is max 200℃. The usual temperature is 150℃.
5. The heating section is equipped with rock wool insulation and air insulation, which has the lowest impact on the cold room. surface temperature
5℃ higher than room temperature
6. The intake and exhaust air doors can be adjusted to effectively control the micro pressure in the furnace.
7. The front of the glass fiber insulation layer in the heating zone can be opened, which is the most convenient for cleaning and maintenance.
8. The furnace adopts a blast circulating return air method, and is designed with BY PASS pipelines as needed
It is necessary to adjust and supplement fresh air to reduce heat loss and save energy.
9. The hot air is designed in a convection type from top to bottom. Prevent material displacement
10. The air duct in the furnace is equipped with a high-efficiency filter with a filtration efficiency of 99.97%, Class 100, and a temperature resistant 280 degree filter to ensure the cleanliness of the furnace.

System control
1. MITSUBISHI programmable controller.
2. Digital Proface man-machine interface.
3. Three-color indicator light: red, yellow, green and orange head show the real-time status of the machine
