Non-oriented silicon steel sheet is an important material used in the manufacture of power transformers, motors and generators. It is made of high-quality silicon steel material with low loss, high magnetic permeability and stable magnetic properties. This material is widely used in the power industry and can effectively reduce the energy consumption of equipment and improve overall efficiency.
Raw material preparation: First, high-quality silicon steel materials need to be prepared as raw materials for manufacturing non-oriented silicon steel sheets. These raw materials are usually cold-rolled non-oriented electrical steel sheets containing silicon.
Hot rolling: After the raw materials are heated, the raw materials are rolled into the required thin plates through the hot rolling process.
Annealing treatment: The thin plate is annealed to eliminate stress and improve the structural uniformity of the grains, thereby improving the magnetic properties of silicon steel.
Surface treatment: After cleaning, pickling, etc. to remove oxides and other impurities, and then insulating coating treatment, usually with organic resin or oxide coating.
Cutting: The surface-treated silicon steel sheets are cut according to the size required by the customer.
Packaging: Finally, after strict quality inspection, the non-oriented silicon steel sheets are packaged according to the specifications for easy transportation and storage.
