The manufacturing process of thinner silicon steel sheet iron core
Generally speaking, when it comes to transformer iron cores, they are actually thinner silicon steel sheet iron cores. When it comes to silicon steel, it is a type of steel containing silicon (also known as silicon). In this regard, its silicon content will be between 0.8% and 4.8%. The thinner silicon steel core is largely due to the fact that silicon steel itself is a magnetic material with strong magnetic properties.
Beside the energized coil, the thinner silicon steel core itself will generate a relatively large magnetic induction intensity, which will greatly reduce the volume of the transformer.
Generally speaking, when using thinner silicon steel sheet cores for transformers, it is important to choose cold-rolled silicon steel sheets with a thickness of 0.35mm. According to the required size of the core, it is cut into elongated pieces, which are then directly overlapped to form a "Japanese" or "mouth" shape to a large extent. In theory, if it is to reduce eddy currents, the thinner the thickness of the silicon steel sheet, the narrower the spliced strips, and the better the effect.
In this way, for thinner silicon steel core sheets, not only will eddy current losses be reduced and its temperature rise be lowered, but materials used on the silicon steel sheets can also be saved. However, when it comes to actually making thinner silicon steel sheet iron cores. Not only does it start from the favorable factors mentioned above, but also because making the iron core in that way will not only greatly increase the working hours, but also greatly reduce the useful cross-section on the iron core.
Finally, when using silicon steel sheets to make thinner silicon steel sheet iron cores for transformers, we should not only start from specific situations, weigh the pros and cons, and choose the best scale. For its transformer, it is made according to the principle of electromagnetic induction, and there are actually two windings wound on the closed iron core column, one is the primary winding and the other is the secondary winding.
