Gas-Electric Hybrid Alumium Brazing Furnace, Hydrogen Brazing Furnace , Refractory Material
In 2012, aojie began to work with the world's largest supplier of automotive air conditioners, Germany Behr. All the branch offices of Behr use gas eletric hybrid heating alumium brazing furnace produced by Aojie. It has been successfully accepted and put into operation.
The degreasing furnace is heated by natural gas or electricity. The oil on the core will be removed by stir fan through circulating hot air. During this process, the lubricating oil will be evaporated,then burning in the incinerator. The temperature control of this furnace is adjusted by PID. Within the width of mesh-belt, the temperature uniformity will be within ±10.
The final exhaust gas is below 300°C, the screw blades are designed in the muffle to acieve dwell time (1s at least) and 95% splitting efficiency. Before entering the combustion chamber, the exhaust gas from degreasing furnace must be transferred by heat exchanger, and the temperature of exhaust gas after heat exchange is not lower than 400°C. The heat efficiency is more than 50%.
The whole spray chamber is designed in a shape of "Rhino". Several windows are setting on both sides to observe the working status in different zones. Since the fluxes power will adhere to the window and influence the effect, each window is designed with manual cleaning and lighting function.
The dry oven is heated by natural gas. The wet core from spray chamber will evaporate moisture completely in the dry oven.
The pre-heating furnace is connected to the inlet curtain box and heated by natural gas. Within the width of whole belt, the furnace temperature uniformity will be within ±5°C(Based on the same section of the moving section). The temperture divation of core will be within ±2°C.
The inserted heating elements are arranged in multiple zones to heat up workpiece to brazing temperature. It is flexibly designed the heating speed as per different workpiece and process requirement. The individual SCR is used to balance heating demand in each zone. Within the range of whole belt width, the furnace temperture uniformity will be within ±3°C (Based on the measurement on the same section of moving workpiece)
Xi'an Aojie Electric Heating Equipment Engineering Co., Ltd.
Xi'an Aojie Electric Heating Equipment Engineering Co., Ltd. is a premier manufacturer of mesh-belt controlled atmosphere continuous brazing furnaces and industrial heat treat systems.
Started in early 1990s, 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.
To serve the aero-space & aviation industry, Aojie developed
high, intermediate and low temperature high precision electric
heating car bottom furnaces which meet temperature uniformity
requirements set by US Military Specifications.
Aojie also developed BAB production lines for the production of
stators and rotors of high efficiency and power economized motors.
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.
