Importance of automation of continuous brazing furnace

The importance of continuous brazing furnace automation:

1. The spray body is a circular structure with passivation treatment on the surface, which not only ensures the beautiful appearance, but also makes the recovery effect of flux better. It can effectively prevent the flux accumulation in the spray room, and the cleaning is also very convenient. The circular structure adopts real high-pressure fan, the pressure can reach 280mbar, and with the special air nozzle, the wind speed can reach 50-200m / s, which can effectively blow off the residual flux on the surface.

2. Spray mixing system contains a lot of humanized design, flux recovery tank is installed with impurity filter, which can filter most of tiexu. The barrel is designed as a deep barrel structure, which can effectively prevent the flux from overflowing due to stirring and affect the appearance. The upper part of the barrel is equipped with Omron liquid level control, which can alarm the lack of liquid.

3. The brazing furnace adopts all fiber structure (all around cotton). After long-term verification, the furnace has better heat preservation performance, which can save 2-3 hours of heating time and 10-20% of electric energy during long-term operation. The main performance of the furnace is fast response speed, low heat storage capacity, good heat preservation performance and no expansion effect.

4. The main component of the brazing furnace is furnace liner, which is 12m one-time forming, that is, there are only two welding seams on two sides and two V-shaped grooves at the bottom.

5. The nitrogen preheating system is installed in the slag cleaning room. Since the slag cleaning room has a high temperature, at 500-600 ℃, when it is not used, these high temperatures also need to be discharged out of the room, resulting in a certain amount of energy loss. Now we Hengda furnace industry can preheat nitrogen to 350-400 ℃ through special process structure such as slag cleaning chamber, internal installation of loose belt, nitrogen circulation, etc., which indirectly reduces the energy consumption of brazing furnace due to nitrogen heating.

6. For the energy-saving design of nitrogen, the loss of nitrogen is mainly at the inlet and outlet. How to ensure the loss of nitrogen is the key to save nitrogen. The conventional design will make nitrogen overflow from both sides of the metal curtain, and the metal curtain will roll after long-term use, which can not achieve the expected effect. At present, our company has inserted metal curtain and high temperature polyester cloth from the top to make the connection between the two sides of the furnace and the metal curtain closer. The metal curtain will curl after long-term use, but we still have high-temperature polyester cloth on the outer layer, which will still block the nitrogen overflow.

7. Automatic electrical control system, program preset manual and automatic two undisturbed switching mode, can accurately record the temperature curve of each zone, at the same time can copy the computer and use Excel analysis. The programmed control of brazing furnace can set the required heating time conveniently and make contribution to the protection of furnace furnace. According to the different temperature requirements of different products, it has the function of one key switching process products. The touch screen can monitor the faults of each line, motor, temperature control and frequency converter in real time, timely detect and alarm, and display and store in Chinese.

8. Remote control function, in the case of equipped with network cable, can use computer, mobile phone and other real-time connection with touch screen, can view or remote control, also can be used for remote maintenance. The main parts of brazing furnace can also be viewed on the screen (optional).
