The composition, characteristics and classification of Kehua's brazing furnace
The brazing furnace may not be seen much in life, but you must know the things produced by it, such as small tableware, knives, etc., which are mainly used in the steel and metallurgical industries. The brazing of Kehua brought by the editor The composition, characteristics and classification of the furnace are introduced. Brazing furnace Application field Brazing furnace is used in steel industry, metallurgical industry, etc. Mainly used for filter refrigeration parts in the automotive industry, aerospace industry, but also for brazing and bright heat treatment of refrigerators, air conditioners, electronics, microwave magnetron industries and other stainless steel, carbon steel, brass, copper parts. Components The components of the brazing furnace are: degreasing furnace → spray system → drying transmission → drying furnace → drying passive, brazing passive → front chamber → brazing furnace → water cooling (dry cooling) → strong air cooling → brazing Furnace transmission. Features Fine and reasonable heating furnace partition of the brazing furnace, hardware selection and software parameter adjustment of high-precision advanced temperature control instruments, furnace temperature control accuracy is extremely high (±1℃), and temperature uniformity in the brazing area is within ± Within 2°C to ensure sensitive and critical temperature requirements for brazing. Brazed in a vacuum atmosphere to keep the workpiece clean and bright. In fact, there are many types of brazing furnaces, such as: copper brazing furnace, aluminum brazing furnace, mesh belt brazing furnace, vacuum brazing furnace, NB continuous brazing furnace, continuous drying furnace, power regulation and voltage control System, HB continuous brazing furnace, JNB periodic brazing furnace, XNB periodic box brazing furnace, etc. Vacuum brazing furnace is a large-scale heat treatment equipment, capable of vacuum brazing, vacuum annealing, vacuum aging and other processing. A number of different programs can be programmed, and hundreds of heat treatment curve points can be controlled and programmed, divided into upper, lower, left and right, front and rear temperature control zones, multi-point and single-point temperature recorders and over-temperature protection devices, uniform furnace temperature The temperature can be controlled within ±3℃, and it is also equipped with high-purity nitrogen and high-flow strong cooling device. The equipment has the advantages of large furnace loading and high efficiency, and does not require supplementary processing products for complex parts and parts with special requirements. Mainly used for vacuum brazing of aluminum products such as aluminum alloy heat exchangers, brazing of stainless steel, titanium alloys, hard alloys, high-temperature alloys, non-ferrous metals and vacuum return of high-speed steel, tool steel, bearing steel, stainless steel and other materials. Fire, aging and annealing treatment of non-ferrous metals and vacuum brazing of stainless steel heat exchangers, oil coolers, and stainless steel thermos cups. Working principle The vacuum system of vacuum brazing furnace equipment is mainly composed of vacuum chamber, pump system, various control valves and heat exchangers. The pump system consists of a mechanical pump, a maintenance pump, a Roots pump, and a diffusion pump. The valve consists of front stage valve (butterfly valve), bypass valve (butterfly valve), maintenance pump valve (butterfly valve) and high valve (plate valve). Brazing furnace The above is the composition, characteristics and classification of Kehua's brazing furnace brought by Xiaobian.
