furnace brazing process

Controlled Atmosphere , Aluminum Brazing Furnace , Continous , Hard Brazing


Aluminum brazing furnace is designed for the continuous brazing of the following products such as aluminum water radiator, oil cooler, intercooler, serpentine type condenser, evaporator, parallel flow condenser, laminated type evaporator, air cooler of power station under nitrogen atmosphere etc.



  • High performance refractory material is adopted to ensure the superior insulation feature of the furnace with low energy consumption while empty load. The excellent designing and manufacturing of the gas distribution system and atmosphere curtain of the furnace ensure the low consumption of purified nitrogen and save the furnace atmosphere so as to decrease the production cost.
  • Fine and reasonable arrangement of heating zones of heating furnace, the selection of the hardware of high precision and advanced temperature control meters and the regulation of software data ensure the very high precision of temperature controlled of the furnace (±0.2℃) and temperature difference (≤±3℃) of the products in brazing section (575℃~610℃) .
  • Advanced frequency conversion mesh-belt speed control system realizes stepless speed change transmission and precise control runtime of workpieces in each heating zone so as to realize the precise heating curve of aluminum brazing.
  • High precision oxygen analyzer has provided an advanced means for measure the atmosphere of the aluminum brazing furnace timely and accurately.
  • The spray fluxer has the features of compact in design and straightforward operation. The spray nozzle insures adequate spray on the workpieces. Air blower insures that the extra flux can be blew off.
  • High speed circulating air and high heating ability of dry oven ensure the parts going to the furnace will not bring any moisture which will affect the brazing quality.
  • Water cooling section realizes the cooling temperature could be controlled and satisfies the requirement of process curve so as to make the metallurgical structure of the joints fine and compact.
  • The blower in air cooling chamber has the features of strong cooling capacity and low noise, the clean and comfortable working environment of the operators is guaranted.
  • Sophisticated controlling system, overall warning and protective system insure the safety of both furnace and operators.

About Aojie

Started in early 1990’s Xi’an Aojie designed and manufactured its first mesh-belt controlled atmosphere continuous brazing furnace. In the years that have followed, Xi’an Aojie has committed to independent research and development of advanced brazing furnaces and heat treat equipments. Nowadays, Aojie mesh-belt continuous controlled atmosphere brazing furnace has successfully replaced imported equipment due to its unique advantages. Aojie mesh-belt controlled atmosphere brazing furnaces are widely used for brazing parts of stainless steel, carbon steel, aluminum, brass and copper, etc. by the industries of automobile, aero-space & aviation, and household appliances, etc.

Xi’an Aojie is a full service supplier, beginning with initial technical services such as feasibility studies, facility analysis and planning, continuing through equipment manufacturing, system installation, furnace start-up and operator training.

Aojie is always untiringly seeking to provide dependable equipment and technical support for customers to manufacture high-quality and low-cost products.


Technical characteristics of aluminum brazing furnace


Process flow of aluminum brazing:Put on the parts - degreasing (heat degreasing or water cleaning degreasing)- brazing spray - drying - preheating - brazing - cooling (under protective atmosphere)- strong cooling – take down the parts


The atmosphere in the brazing furnace is significant during the brazing process, it requires that the Oxygen concentration should be below 10 ppm and the drew point is lower than -72°C. The temperature uniformity of the same product is especially important when the brazing temperature is reached, the general requirement is ±3℃. The requirements for some products are even higher


Main characteristics of aluminum brazing furnace


  1. From the stirring of brazing agent, spraying, drying, brazing to cooling are continuously and automatically operated, which ensures the mass production reliably and saves the cost to the greatest extent.
  2. The parameter related to the brazing quality like drying temperature, brazing speed, brazing temperature, warming up rate, nitrogen flow and pressure will be automatically controlled after setting the program which ensures the product stability.
  3. All key components are procured globally to ensure the reliability of aluminum brazing furnace.
  4. The muffle chamber in the furnace is made of imported stainless steel plate (SUS316L) with a thickness of 8mm or more.
  5. Aluminum brazing furnace adopts advanced automatic temperature control technology, temperature control accuracy is 1°C.
  6. The advanced atmosphere protection design of aluminum brazing furnace ensures that the N2 in the furnace is fully protected when the brazing furnace is in operation, and the amount of N2 is minimum.
