Development and Application of Multi-chamber Continuous Vacuum Furnace

This article introduces the performance, structure, characteristics of the multi-chamber continuous vacuum furnace and its applications in the fields of vacuum brazing, vacuum sintering of powder metallurgy materials, vacuum heat treatment of metal materials, vacuum exhaust and sealing of electronic devices and stainless steel heat preservation containers. status quo.

Vacuum resistance furnace is an important industrial heating equipment developed in the 1940s. It is widely used in active metals such as titanium, zirconium, tungsten, molybdenum, niobium, refractory metals and their alloys, aluminum foil, electrical pure iron, soft Non-oxidation bright annealing of metal materials such as magnetic alloys and copper tube strips; bright quenching of high-speed tool steel and die steel; stainless steel, titanium, aluminum, copper, cemented carbide, high-temperature alloys, ceramics, etc. Flux-free vacuum brazing; vacuum sintering of powder metallurgy materials such as hard alloys, rare earth permanent magnet materials, neodymium iron boron, etc.; vacuum exhaust and sealing of electronic tubes, vacuum switches, and stainless steel heat preservation containers. It is increasingly playing an increasingly important role in industries such as aviation, aerospace, ships, vehicles, machinery, electronics, petrochemicals, tools, materials, and home appliances.

At present, the vacuum furnaces used in the above-mentioned industries in my country are basically single-chamber or double-chamber batch vacuum furnaces. The disadvantages are low efficiency, high energy consumption, high cost, small output, and not suitable for mass production. In order to overcome the above shortcomings of batch vacuum furnaces and meet the needs of mass production in modern industry, Shenyang Vacuum Technology Research Institute has developed single-chamber and double-chamber batch vacuum furnaces for many years to address the key technical problems of continuous furnaces. Tackling key problems, independent development, careful design, using a number of original key technologies, successfully developed the first domestically made multi-chamber continuous vacuum furnace, filling the technical gap in this field in China, and breaking the monopoly of developed countries in this field status. The equipment has been successfully tested at the user site in October 2002 and has been put into use steadily. This product is a fully automatic assembly line multi-chamber combined mechatronics vacuum heating equipment. Its structure is novel, easy to operate, advanced in performance, reliable in operation, domestically pioneered, and internationally leading. The overall technical performance of the equipment has reached and exceeded that of similar products in developed countries. Level, it is the ideal equipment for upgrading the traditional single-chamber batch vacuum furnace.

The multi-chamber continuous vacuum furnace is based on the successful experience in the development of single-chamber and double-chamber batch vacuum furnaces for many years, and comprehensively uses vacuum acquisition, pressure vessels, mechanical transmission, high temperature heating and heat insulation, pneumatic and hydraulic pressure, and programmable automation. Control and computer monitoring and many other engineering technologies; adopt modular combined pipeline type overall plan, roller bottom vacuum continuous transmission, pneumatic gate valve isolation gas and isolation high temperature composite technology, multi-zone PID closed-loop program temperature control, advanced touch screen + PLC+ A number of advanced technologies such as computer automatic operation control; a new generation of vacuum heating furnaces that are optimized and carefully developed for vacuum heat treatment, vacuum brazing, vacuum sintering, vacuum exhaust and sealing, etc. The ideal equipment for upgrading the single-chamber intermittent vacuum furnace and vacuum exhaust station; it will be used for vacuum heat treatment, stainless steel brazing, neodymium iron boron sintering, vacuum switch and stainless steel double-layer vacuum insulation container exhaust and sealing industries The majority of users improve product quality, expand production scale, improve work efficiency, and open up market space to provide strong technical support and reliable equipment support.
