Product Description:
Well-type vacuum annealing furnace (hereinafter referred to as electric furnace) is mainly used for tempering and annealing of various workpieces in less or no oxidizing atmosphere.
The structure of the electric furnace is mainly composed of the furnace body, the furnace gallbladder, the furnace cover, the vacuum pumping device and the temperature control system.
The shell of the furnace is made of steel and steel plate, and the aluminum silicate refractory fiber module and ultra light high alumina foam brick are built in the furnace.
The corrugated strip heating element is fixed on the lining cotton by high alumina ceramic nails.
In the furnace, a heat-resistant plate is tightly welded to form a furnace gallbladder, and the treated workpiece is placed in the furnace gallbladder.
A fan is installed on the cover of a well-type vacuum annealing furnace to force air circulation so as to make the temperature and gas in the furnace uniform.
The furnace cover is sealed with the flange of the furnace biliary opening, and the vacuum device is connected with the furnace cover.
The temperature control system adopts PID programmable control, which has the functions of over-temperature alarm, fault self-diagnosis and so on.
 
Purpose:
Well-type vacuum annealing furnace is a national standard energy-saving industrial electric furnace. It is mainly used for vacuum annealing heat treatment of various mechanical parts. It is widely used in stress relief annealing, bright annealing, vacuum degassing of various metal materials, alloy materials, crystal materials, etc. Through different configurations, protective atmosphere can also be introduced for nitriding and carburizing heat treatment.
Operation mode:
Wellbore vacuum annealing furnace series products are operated by pre-vacuum atmosphere protection. The furnace is first pumped to a certain vacuum degree and then filled with high-purity nitrogen or ammonia decomposition atmosphere for protection heating, so as to achieve the goal of less oxidation-free heating and no decarbonization and brightness. Because of the use of agitating fan, the furnace has high temperature uniformity. It can be applied to bright non-oxidation annealing of mechanical parts, silicon steel sheets, copper, copper and wire rods.
 
Structural Introduction:
The shell of the well-type vacuum annealing furnace is of the well-type furnace body structure. The vacuum tank body is made of imported high-quality stainless steel. There is no leakage in X-ray inspection. All automatic control of well vacuum annealing has safety protection design. When the furnace cover is opened, the control power is automatically cut off. When the furnace cover is closed, the heating can start to ensure the safety of operators.
