Silicon steel thin plate is a kind of technical and economical material which is widely used in electrical industry and mechanical industry. It is a composite material made of metal and dielectric, with good electrical and magnetic properties, low power loss, high surface insulation resistance and high temperature for long-term use. The production of silicon steel thin plate is a complex process. There are several main steps involved in its production.
The first step is to use steel as raw material, the purity of which should reach more than 99%, the carbon content should be less than 0.04%, and the impurity should not be more than 0.02%. The raw material should be tested by testing instrument and then be cut into slender wire of 0.1-1mm and then annealed.
The second step is to make a steel lamination. A lamination is composed of a high permeability steel and an insulating material, and its purpose is to allow electrical current to flow through it more efficiently and reduce energy loss. Both the material and the manufacturing process for the lamination are very important, and it must be made with precise measurements and appropriate heat treatments.
The third step is to roll the laminated steel sheet into thin plate. This process needs to be carried out using advanced machines. The material must be rolled by precise speed and angle. At this step, its thickness can be reduced to 0.2 mm or even 0.1 mm. This process also allows for automating the production and ensuring product quality.
After the rolling process, the steel plate is flattened using an edger and cut into different sizes. The thickness of the plate is measured and the insulating material must be tested. It makes sure the electrical properties of the steel plate meet the requirements.
Finally, the silicon steel sheet is passivated and then the finished products are inspected and stored. Passivation is a chemical treatment that increases electrical resistance and corrosion resistance. It also prevents the occurrence of surface oxidation.
In summary, silicon steel thin plate production is a complex process, which involves many steps including steel as raw material, lamination, rolling, flattening, cutting, insulating material test, passivation and inspection. With the development of technology and machinery, the production cost of silicon steel thin plate has been greatly reduced. It is widely used in electrical and mechanical industries, and is an important part of modern technology progress.
