Non oriented silicon steel coil, also known as non-oriented electrical steel, is a special electrical steel material. It is obtained on the basis of ordinary silicon steel by special rolling and annealing processes. The main feature of this material is that its grain structure presents a non-oriented state. That is, the orientation of the grain has no obvious orientation. So that its magnetic properties in different directions are basically the same.
How to Produce
1. Steelmaking: Using high-purity raw materials, smelting by converter or electric furnace, controlling chemical composition and temperature to obtain high-quality molten steel.
2. Continuous casting: The workers will continuously cast the molten steel into a certain specification of slabs to provide raw materials for the subsequent hot rolling process.
3. Hot rolling: Workers heat the slab and then roll it at high temperature to form a hot rolled strip with a certain thickness.
4. Pickling: Remove the oxidation scale on the surface of the hot rolled strip to provide a clean surface for the cold rolling process.
5. Cold rolling: at normal temperature, workers roll hot rolled strip steel several times to make the desired sheet.
6. Annealing: In order to eliminate the internal stress generated during the cold rolling process and improve the magnetic properties and processing properties of the silicon steel sheet, it is necessary to annealing.
7. Finishing: trimming and leveling the annealed silicon steel sheet to obtain a non oriented silicon steel coil that meets the requirements.
