Speed Controller With Inverter , Furnace Brazing Equipment , High Temperature

Overview

The gas heating brazing furnace is based on the knowledge of our technicians as well as the advanced experiences of the overseas countries, such as Japan, Germany and so on. We integrate both parts and are innovate to create this new type of furnace.

Hard brazing

brazing solder has a melting point of more than 450°C and high joint strength,The strength of hard brazing joints is high, some kinds of brazing solders can be used in high temperature. There are many kinds of solder for hard brazing, the most widely used solder based on aluminum, silver, copper, manganese and nickel. Aluminum base solder is often used for brazing aluminum products.Silver base copper filler metal is often used for brazing copper and iron parts.

The gas heating brazing furnace is largely made of pre-heating zone, heating insulation zone, cooling zone, heat exchanger, gas heating system, mesh belt transmission mechanism, carrier gas supply, water cooling system and control system.

Advantages

The high precision micro-processor controlled thermometer and PLC are responsible for the control of furnace temperature. The variable-frequence governor is used for the mesh belt transmission control. Muffle adopts the heatproof material, specifically, the steel plate with rare earth elements. The fireproof with high thermal insulation performance material is used in the heating furnace . In order to guarantee the safety and effectiveness, the warning device is well equipped.

Brazing Classification

Flame brazing: The welding is carried out by using mix burning flame of combustible gas mixed with oxygen or compressed air as heat source

Dip brazing: Dip part or whole of the workpiece into a solder bath covered with soldering agent or the salt bath with moltan salt. This method ensures the uniform and rapid heating as well as accurate temperature control, it is suitable for the mass production and brazing of large components. The salt in the salt bath is mostly composed of flux. A large amount of soldering agent is usually left on the workpiece after brazing, and the cleaning work is heavy

Induction brazing: Welding method using high frequency medium frequency or power frequency induction current as heat source. High-frequency heating is suitable for welding of thin wall pipe fittings. It is especially suitable for welding of large components, such as pipe joints which need to be disassembled on rockets.

Furnace brazing: Put the workpiece assembled with solder into the furnace for heating and welding, brazing agent is often required, It can also be protected by reducing or inert gases. Continuous furnace can be used in mass production

Vacuum brazing: The workpiece is heated in a vacuum chamber and is mainly used for welding of high quality products and oxidizable materials

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.
