Machine Introduction
This is a continuous production aluminum brazing furnace, which uses a mesh chain to transport aluminum products to achieve efficient production. It is one of the important brazing equipment for many aluminum products at present, and is suitable for battery cooling plates, automotive engine radiator, condenser, evaporators and other products
The maximum design temperature of the brazing furnace is 700 ℃, and there are nitrogen pipes in the tunnel. The atmosphere in the high temperature environment is control to meet the requirements of aluminum brazing, so as to prevent poor chemical reaction of aluminum materials during high temperature brazing, leading to oxidation and other defects
The control system of this brazing furnace adopts the most advanced components. PLC and electric drive are from Siemens and Mitsubishi brands. The entire operating system conforms to the intelligent operating specifications of modern industrial production, allowing engineers to preset temperature control methods and achieve remote access to equipment operating parameters
Advantages of aluminum brazing furnace
- The material of the tunnel is stainless steel 316L, which can remain stable at a temperature of 1350 ℃ and maintain temperature stability, ensuring a service life of up to 15 years for this machine.
- The tunnel in the brazing area adopts a multi-layer structure design, which not only maintains temperature stability and uniformity, but also prevents heat from spreading outward, ensuring that each kilowatt hour of electricity consumption is not wasted and reducing the cost of electricity use.
- Advanced temperature control system, temperature data collected by thermocouples will be converted into digital signals and displayed on the touch screen, so that engineers can clearly know the operating status of aluminum brazing furnace.
- This brazing furnace has the latest manufacturing technology. Compared with our competitors’ machines, its power consumption has decreased by 22%, and nitrogen consumption has decreased by 45%. This design is very consistent with the requirements of modern industry to reduce costs and increase efficiency, and also very consistent with the concept of energy conservation and emission reduction.
Aluminum brazing furnace technical details
Temperature control
The temperature control of aluminum brazing furnace is a complex process, and a small mistake may lead to the scrapping of a batch of products. In order to solve this problem, we upgraded its temperature control system. First, we useing more advanced thermocouples to collect temperature data, and all the temperature data were displayed in digital form. Second, we simplified the temperature operation process, and built in a number of preset temperature data formulas. Even novice engineers can master this brazing technology in a short time
Multiple temperature zones
We divide the temperature of a aluminum brazing furnace into several independent control areas. When the temperature changes in each control area, the brazing quality will not be affected. This method can effectively increase the temperature uniformity and improve the brazing quality
Steps for preset heating
The heating process is automatically control, and engineers can preset the temperature rise curve through the touch screen to control the slow temperature rise. This can effectively increase the uniformity of tunnel temperature, reduce the power supply pressure of factory transformers, and ensure stable current output of transformers
Independently displayed average temperature
There are two independently displayed average temperatures in the brazing zone. Engineers cannot control those temperatures. It is the average temperature of the temperature collected by multiple thermocouples converted by the central processor. With reference to this temperature, it can effectively make predictions. Engineers can quickly improve the operating speed of the brazing furnace and improve the quality of aluminum products

Aluminum brazing furnace flux spraying
Spraying flux is a very important step. Almost every aluminum part needs to be spraying with NOCOLOK flux, automobile radiator and condenser. These parts are spraying with flux after the aluminum core is assemble. The battery cooling plate of the battery car needs to be spraying with flux first, and then assemble,
This aluminum brazing furnace has an automatic flux spraying part, and has two storage tanks, two flux of different proportions. The flux of one tank is the surface of the aluminum core, and the flux of the other tank is the header plate of the aluminum radiator. Moreover, the excess flux will be recycled, and they will automatically flow to the storage tank, and then be reused again.
When the flux is spraying, the aluminum core will pass through an air duct, and the strong air pressure will blow away the excess water, making the aluminum core of the radiator easy to be drying. This process does not require manual participation, and the spraying device is automatic.
Aluminum brazing furnace optional configuration
The user can choose to install the oxygen content monitoring system in the furnace. It is an independent instrument that displays the oxygen content in the furnace online. If the oxygen content is higher than the preset value, the brazing furnace will give a warning sound,
If the oxygen content in the furnace is too high, it will affect the quality of brazing. It is one of the effective methods to prevent large-scale defects in aluminum cores during brazing. Due to the high price of this instrument, some small factories may not need it for cost reasons. Therefore, we have made this instrument an optional configuration, and users can choose whether they need it according to their own requirements,
In the normal production process, experienced engineers drive the aluminum brazing furnace. With or without this instrument, the quality of aluminum products produced is the same
