1) The role of the annealing furnace:
1. The amorphous alloy transformer core annealing furnace is specially designed for the
annealing and stress-relieving of amorphous transformer cores, and satisfies the stress-
relieving annealing treatment of the formed iron cores under the magnetic field. 2. During the annealing process, nitrogen protection is required to prevent the surface of the
iron core from being oxidized. It can obtain good loss characteristics, so as to achieve the
effect of energy saving and environmental protection of the amorphous transformer. 2)Technical parameters

Specifications: 8×80mm, installed at the bottom of the box and well insulated from
the oven body (low voltage). Furnace System Structure
Structure type Monolithic structure. Door opposite door
Door seal The door frame has three seals, and is sealed with ceramic fiber square rope, which
has good sealing performance. Furnace shell
skeleton
Q235 channel steel, made of angle steel welding, after anti-rust treatment, sprayed
with amino self-drying paint. Furnace shell After the Q235 steel plate is treated with anti-rust, it is sprayed with amino self- drying paint. Furnace skeleton Q235 channel steel, angle steel welding, after anti-rust treatment, sprayed with high
temperature resistant silver powder paint. Furnace inner liner Made of SUS304 stainless steel plate, connected by screws and argon arc welding, and treated with high temperature deformation prevention. There are expansion joints
between the liner board and the board, which is convenient for free expansion and
contraction at high temperature. Insulation Materials It adopts high-density high-quality aluminum silicate cotton + ceramic fiber blanket
double combination filling structure. Insulation effect The temperature of the outer surface of the furnace body, from the start of the
annealing furnace to the temperature of the furnace after the furnace temperature
reaches the working temperature, does not exceed 30 °C. Insulation layer

Blower impeller Using SUS700*25 multi-wing fan blades, blades and hubs are welded. And do anti- deformation treatment. Heating System
Electric Heaters
1. The electric heating rod is made of U-shaped stainless steel electric heating tube to
reduce deformation. The heating rod is fixed firmly and reliably. The joint is made of
stainless steel nut, and measures are taken to prevent thermal expansion and cold
contraction from loosening.
2. In order to prevent the local temperature of the electric heating tube from being too
high, the heating density of the electric heating tube is controlled at 2-2.5w/cm2. Nitrogen inlet
