Silicon steel coil

Silicon steel coils are divided into non-oriented and oriented. In terms of chemical composition, the silicon content of oriented silicon steel is higher than that of non-oriented silicon steel (the silicon content of cold-rolled non-oriented silicon steel sheets is 0.5%-3.0%, and the silicon content of cold-rolled oriented silicon steel sheets is above 3.0%).
Non-oriented silicon steel is used in rotating equipment such as motors. It is divided into iron cores and rotors. In order to be easily magnetized during the rotation process, electrical energy is converted into mechanical energy. Therefore, it is required to be easily magnetized at every angle during the rotation process, so the grain orientation distribution in non-oriented silicon steel is required to be uniform; while for oriented silicon steel, high magnetic induction is required and no rotation is required, so its texture is basically Goss.
Use, oriented silicon steel is mainly used for transformers, and non-oriented silicon steel is mainly used for motors
Internal structure, the grains of oriented silicon steel are basically in one direction, so it is called oriented, and the grains of non-oriented silicon steel are arranged in a disorderly manner, so the heat loss of oriented silicon steel is small, and the heat loss of non-oriented silicon steel is large.
The manufacturing process is also different. Oriented silicon steel is much more complicated than non-oriented silicon steel.
Thickness: Oriented silicon steel thickness is 0.23-0.35 mm, and non-oriented silicon steel thickness is 0.35-0.65
A. Low iron loss. The most important indicator of quality. All countries in the world classify grades by iron loss value. The lower the iron loss, the higher the grade and the higher the quality.
B. High magnetic induction intensity. Silicon steel sheets with higher magnetic induction under the same magnetic field can make the motor or transformer core made of it smaller in size and weight, which can save silicon steel sheets, copper wires and insulation materials.
C. High stacking coefficient. The surface of silicon steel sheets is smooth, flat and uniform in thickness, and the stacking coefficient of the core is improved.
D. Good punching performance. This is more important for the manufacture of small and micro motor cores.
E. The surface has good adhesion and weldability to the insulating film, which can prevent corrosion and improve punching performance.
F. Small magnetic aging phenomenon
G. Silicon steel sheets must be annealed and pickled before delivery.

High magnetic conductivity: can effectively reduce hysteresis loss and improve electromagnetic induction conversion efficiency.
Low hysteresis characteristics: the change of magnetic induction intensity is small during magnetization and demagnetization, which can reduce the energy loss of the core material.
Reduced energy consumption: can effectively reduce the energy consumption of motors, transformers and power generation equipment, and improve energy utilization efficiency.
High saturation magnetic induction intensity: makes the output power of the motor higher and improves the overall performance of the equipment.
Silicon steel coil process: raw material preparation → cutting → longitudinal shearing → surface treatment (such as pickling, electroplating) → edge trimming → stamping → welding (if necessary) →cleaning and degreasing.
