- The brazing oven is the critical part of the aluminum radiator brazing furnace line.
- To save electricity consumption, the furnace uses natural gas heating to preheat the stove to a temperature of 500℃, leaving more time for brazing.
Equipment Advantages
1) The CAB aluminum radiator brazing furnace adopts high-performance porcelain fiber cotton material for heat preservation.
The furnace can rise to 630℃ from the ambient temperature in around 2 hours.
2) The muffle of the brazing oven is once-formed by the large size bending machine and is made from Sweden 316L steel plate and
304 steel plate. A 10M muffle is formed by one-time bending, and only one v-slot is at the bottom. The one-time
Forming muffles could reduce the misshapen effect at welding and deformation during heating.
3) The furnace zones are divided based on the upper, lower, rear, and back areas. The heating power is adjusted through the PID
regulator so that the stove can achieve an ideal temperature uniformity of ±1℃. The brazing area could achieve a temperature
uniformity of ±2℃ to meet the brazing requirements.
4) The temperature controller has the PID regulation function to achieve a smooth temperature rise. Also, the temperature controller
has an over-temperature alarm. The mesh belt is steplessly regulated through the inverter. The driving mechanism is started up in
the acceleration manner and stopped in the deceleration manner to reduce the tension of the mesh belt.
5) the aluminum radiator brazing furnace (CAB) has a complete control system integrating intelligent control,
alarm, and protection systems. The real-time temperature recording function provides the process data of different products.
6) The area of the fluxing chamber which contacts the flux is made of stainless steel material. The two side walls of the fluxing
chamber are both set with an observation window to observe the fluxing performance. The fluxing nozzles have a 90º fan-shape
spraying to prevent nozzle blockage. There is a filtering net for recycling the flux to avoid damage to the fluxing pump.
7) The dry air cooling room is set with a slag-cleaning chamber. A side door of the slag cleaning chamber allows
the worker to clean the flux slags. Compared to the traditional water cooling chamber, the dry cooling room doesn’t risk corrosion because of water and deformation of the chamber because of cold and heat. There is no need for cooling water.
8) power at the temperature rising stage: 100%; power at the brazing stage: ≤60%
