All fiber bright annealing of full hydrogen bell type annealing furnace
Making making full fibre full hydrogen bell type bright annealing furnace is mainly suitable for brass, composite strip, bronze belt, all kinds of precision copper pipe,special-shaped copper strips, copper, minting material, precision strip steel, soft and hard magnetic alloys, standard parts materials, copper alloy wire, stainless steel belt, ten kinds of material annealing. The bell type furnace maximum loading diameter 3.2M, the loading height up to 4M, maximum loading capacity of 80T.
The fiber structure of full hydrogen bell type annealing furnace:
All fiber full hydrogen bell type bright annealing furnace is composed of a heatingcover, two furnace seat, two inner cover and the valve frame:
Heating cover is made of rolled steel ring by welding process, for the hook liftingexchange cover position on the upper cover body, a lower supporting foot three supporting furnace cover, bottom is provided with a sand sealing knife, when heated to a heating cover flange pressure can directly in the furnace cover to be sealed in effect, the other two guide rings, so that the heating cover can conveniently and accurately into the furnace seat.
The whole fiber lining of aluminum silicate needled felt folded block combination,so that greatly reduces the cover body weight, not only improve the heat preservation effect and reduces the energy consumption. The heating element adopts resistance with homogeneous suspension in the chamber around, and fixed with ceramic screws, sturdy and durable.
Furnace socket circular shape, made of heat resistant stainless steel plate welding and assembly in each furnace seat are placed in a circular piece of heat-resistant steel furnace bottom and furnace bottom below in several supportingtube welding for bearing the workpiece, the fan in the middle seat of furnace with a strong convection, by the operation of the motor to drive the impeller to strongconvection, so that the temperature inside the furnace to achieve uniform, motor of the fan for cooling sealed double speed motor, can achieve high speed and low speed conversion, pass into the cooling water can ensure that no motorbearing damage due to fever. In the furnace seat equipped with inner coverwater rubber seal ring, so as to achieve the sealing effect.
The furnace for the cover of the corrugated stainless steel into a cylindrical shape, the top is a circular head is welded on the lower part of a flangeconnected to the furnace seat sealing ring, the sealing space is formed inside the furnace, to charge in a protective atmosphere heat treatment.
Electrical control cabinet with PID zero trigger control regulator to adjust thefurnace power and temperature, and a temperature alarm function. According to user needs and making the PC configuration software of dynamic display.
