Gas - Electric Hybrid Aluminium Brazing Furnace Refractory Material CE Certificate

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)
