Heat treatment external processing manufacturer: How is the welding effect of vacuum brazing furnace
Heat treatment external processing manufacturer: Vacuum brazing furnace is a new brazing method under vacuum conditions without adding brazing flux. Due to the fact that brazing is carried out in a vacuum environment, it can effectively eliminate the adverse effects of air on the workpiece, thereby achieving flux free brazing. Mainly used for brazing difficult to brazing metals and alloys such as aluminum alloys, titanium alloys, high-temperature alloys, refractory alloys, ceramics, etc. The brazed joint is smooth and dense, with good mechanical properties and corrosion resistance. Vacuum brazing furnaces are generally not used for welding carbon steel and low-alloy steel needles.
Heat treatment external processing manufacturer: The vacuum brazing furnace technology equipment mainly consists of a vacuum brazing furnace and a vacuum management system, which are divided into two parts. There are roughly two different types of vacuum brazing furnaces: hot fireplace and cold fireplace. Two types of furnaces can be heated with natural gas or electric heating, and can be designed as side mounted furnaces, bottom mounted furnaces, or top mounted furnaces (kang type). Vacuum environment system analysis can be used as a universal approach. The main issues in the research of vacuum control systems include the use of vacuum processing units, vacuum pipelines, vacuum valves, etc. Vacuum unit personnel are usually composed of rotary vane mechanical pumps and oil diffusion pumps. Using a mechanical pump alone can only achieve a vacuum level significantly lower than 1.35 × 10-1Pa on its own. To achieve high vacuum, it is necessary to develop and use oil diffusion pumps simultaneously, which can achieve a vacuum degree of 1.35 × 10-4Pa. The pressure generated by the gas in the system is measured using a vacuum gauge.
