Brightness Bluing and Blacking Treatment , Exothermic Gas Generator, Annealing

Exothermic gas generators produce either a lean or rich atmosphere composition depending on the chosen air-to-gas ratio. Exothermic gas is used for the thermal treatment of metals as a protective gas, which can be generated in an exothermic gas generator through burning natural gas. This process is taking place under heat emission.

For annealing and normalizing process, casting and forging parts, brightness annealing and quenching process should use thick exothermic atmosphere, For brightness treatment process , bluing treatment and blacking treatment can adopt thin thin exothermic atmosphere.

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.
