Iron core is generally made of silicon steel sheet, which is commonly used in transformer. Silicon steel is a silicon-containing steel, and the silicon content is between 0.8% to 4.8%. The silicon steel can be made for transformer's iron core, which is because the silicon steel itself is a magnetic material with strong permeability. In the electrified inductor, it can produce a larger magnetic induction, which can reduce the size of the transformer.
Iron core transformer has the advantages of low no-load current, low noise and so on, which can receive more and more domestic users' favorite. In the production process of the iron core transformer, the annealing of the iron core is very important. Our super audio frequency annealing machine has main features of simple operation, easy to move and no need of professional technicians, etc. So it can be learned within a few minutes.
In general, iron core after the process needs to be heated for annealing with this machine. And the magnetic gap of iron core before and after annealing is relatively large. The original process will cause the material to increase stress, so it needs to cut the stress in order to make up for the lack of raw material organization. After annealing by this machine, it will obtain better grain structure, which can improve the low magnetic field of the magnetic induction, and reduce coercivity.
