Advanced Temperature Control , Furnace Brazing Equipement , Mesh Belt Gas Aluminum
This mesh belt continuous gas aluminum brazing furnace is mainly used for aluminum and iron, stainless steel and aluminum plate, copper etc, . After such equipment treatment, the product surface becomes bright without oxidation.
The furnace boasts stylish design, rational structure, energy saving, high heat efficiency, stable production quality, safe and easy use, not generating industrial pollution.
Advanced temperature control manners: Intelligent thermostat and silicon controlled rectifier ensure temperature control precision of ±1℃. It’s advanced, reliable, practicable and cost effective as an industrial furnace.
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 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.
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.
About us
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.
