The production of silicon steel sheets is known as a handicraft among steel products due to its complex process, narrow process window and difficulty in production, especially oriented silicon steel sheets. Mainly used to make iron cores for various transformers, motors and generators. The world's silicon steel sheet production accounts for approximately % of the total steel production (see Precision Alloys).
Performance requirements
The performance requirements for silicon steel are mainly low iron loss, which is the most important indicator of the quality of silicon steel sheets. Countries all classify grades according to the iron loss value. The lower the iron loss, the higher the grade. The magnetic induction intensity (magnetic induction) is high under a strong magnetic field, which reduces the size and weight of the cores of motors and transformers, saving silicon steel sheets, copper wires, and insulating materials. The surface is smooth, flat and uniform in thickness, which can improve the filling factor of the core. Good punchability is more important for manufacturing micro and small motors. The surface insulation film has good adhesion and weldability, can prevent corrosion and improve film punching properties. Basically no magnetic aging. Typical electromagnetic properties are shown in the table
Generally, as the silicon content of silicon steel sheets increases, the iron loss, punchability and magnetic induction decrease, and the hardness increases. The higher the operating frequency, the greater the eddy current loss, and the thinner the silicon steel sheet selected should be.
Smelting and rolling
Silicon steel is mainly smelted in an oxygen converter (electric arc furnace can also be used), combined with vacuum treatment of molten steel and technology (see refining outside the furnace, using mold casting or continuous casting. Depending on the use, During smelting, the content of silicon (.~.%) and aluminum (.~.%) is changed to meet different magnetic requirements. The amount of silicon and aluminum in high-grade silicon steel sheets is increased accordingly. Carbon, sulfur and inclusions are reduced as much as possible.
The magnetism, surface quality, filling coefficient and punching properties of cold-rolled silicon steel sheets are better than those of hot-rolled silicon steel sheets, and they can be produced in rolls. Therefore, some countries have stopped producing hot-rolled silicon steel sheets since the 1990s. China adopts a low temperature of about ℃ Hot-rolled silicon steel sheets are manufactured by rapid hot rolling and stack annealing under hydrogen protection. The yield rate is high, and the surface quality and magnetic properties of the finished product are good.
The rolling of silicon steel is divided into two processes: hot rolling and cold rolling. The traditional process of directly producing silicon steel finished products by hot rolling is rarely used now. It is mainly produced in two processes: hot rolling and cold rolling, which are called cold-rolled silicon steel products. Depending on the product, the cold rolling process is divided into multi-stand rolling mills. Rolling and single-stand rolling, of which single-stand rolling mainly produces oriented silicon steel products.
