Silicon steel sheet, also known as electrical steel, is a special soft magnetic thin plate rolled with added silicon elements. It features excellent magnetic conductivity, low core loss, low energy consumption, low temperature rise and strong magnetic stability.
As an indispensable core basic material in the electric power, electrical and new energy industries, it is mainly used to manufacture iron cores for transformers, various motors and electrical appliances. It is widely applied in power grid distribution, industrial equipment, household appliances, new energy vehicles, photovoltaic power generation, wind power, charging piles and other fields.
As the core soft magnetic material for electric power, home appliance and new energy sectors, the insulating coating on the surface of silicon steel sheets determines the energy efficiency, insulation stability and service life of equipment.As the key equipment for surface insulation treatment of silicon steel sheets, the roller coating production line adapts to the characteristics of silicon steel sheets - ultra-thin thickness of 0.2-0.5mm and high flatness. It realizes fully automated closed-loop production from raw material pretreatment to finished product unloading, with precise control of every process to ensure stable and controllable coating quality.
First of all, silicon steel sheets are smoothly conveyed by the automatic feeding system and enter the deep cleaning process. Oil stains and impurities on the surface are thoroughly removed to ensure no water marks or residues remain on the sheet surface. This improves the adhesion of subsequent coatings and fundamentally avoids paint film defects.
In the core roller coating process, a high-precision multi-roller collaborative design is adopted, equipped with an intelligent closed-loop control system. It can accurately regulate paint consumption and coating thickness according to silicon steel sheet specifications and coating requirements, enabling uniform application of water-based, oil-based and semi-inorganic insulating paints.
After coating, the silicon steel sheets proceed to the curing process. The coatings are rapidly cured through heating in industrial ovens or ultraviolet irradiation by UV curing machines. Finally, finished sheets are stacked by the automatic unloading system.
The whole process requires minimal manual intervention, enabling 24-hour continuous and stable production and greatly improving production efficiency.
