Qingdao Furunde Microelectronics Co., Ltd.

/, - Vacuum sintering furnace is an energy-saving vacuum furnace, mainly used in aerospace, aircraft manufacturing industry, automobile manufacturing industry, petroleum machinery industry, precision machinery manufacturing industry, vacuum sintering of metal or non-metal materials and parts, and also It can be used for bright non-oxidation and non-decarburization heat treatment and spheroidizing annealing of precision parts or forgings. The product complies with the military standard vacuum sintering furnace of the Ministry of Aviation Industry of China.
< , -Furnace structure: /, -The vacuum sintering furnace is mainly made of steel plates rolled into a well-shaped furnace shell, and the furnace structure is made of profiled steel welded together. The furnace lining is made of typical energy-saving composite fiber, which saves 3-3% of electricity. The electric heating element adopts international standard new high-temperature resistant resistance element. The vacuum sintering furnace uses a rotary vane mechanical vacuum pump and a diffusion pump for continuous vacuuming or nitrogen protection. It is used for vacuum sintering, bright annealing, tempering, quenching and other non-oxidation heating.
< , - Vacuum tank: /, - The vacuum tank is rolled out of stainless steel plates, protected by automatic tight welding, and has been tested and suppressed by the large-scale optical flaw detection room of our factory. The furnace cover is made of stainless steel internal insulation furnace cover. The furnace cover panel and the tank are sealed with dark double water-cooled vacuum rubber. The furnace panel is equipped with a vacuum interface, a protective atmosphere supply interface, and a vacuum pressure gauge. The furnace cover and furnace tank can be lifted out by the workshop crane, and the two real tanks can be operated alternately and continuously to improve production efficiency.
