GB Standard Non Oriented Electrical Silicon Steel Cold Rolled Silicon Steel Coil

Short Description:

The performance requirements for silicon steel are mainly: ① Low iron loss, which is an 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. ② The magnetic induction intensity (magnetic induction) is high under a strong magnetic field, which reduces the volume and weight of the cores of motors and transformers, saving silicon steel sheets, copper wires, and insulating materials. ③The surface is smooth, flat and uniform in thickness, which can improve the filling factor of the core. ④Good punching properties are more important for manufacturing micro and small motors. ⑤The surface insulating film has good adhesion and weldability, can prevent corrosion and improve punching properties.

Product Detail

Silicon alloy steel containing 1.0 to 4.5% silicon and less than 0.08% carbon is called silicon steel. It has the characteristics of high magnetic permeability, low coercivity, and large resistivity, so the hysteresis loss and eddy current loss are small. Mainly used as magnetic materials in motors, transformers, electrical appliances and electrical instruments. In order to meet the needs of punching and shearing when manufacturing electrical appliances, a certain degree of plasticity is also required. In order to improve the magnetic induction performance and reduce hysteresis loss, the content of harmful impurities is required to be as low as possible, and the plate shape is required to be smooth and the surface quality is good.

Features

Silicon steel uses core loss (iron loss for short) and magnetic induction intensity (magnetic induction for short) as the guaranteed magnetic value of the product. The low loss of silicon steel can save a lot of electrical energy, extend the operating time of motors and transformers, and simplify the cooling system. The power loss caused by the loss of silicon steel accounts for 2.5% to 4.5% of the annual power generation, of which the iron loss of the transformer accounts for about 50%, the small motor of 1 to 100kW accounts for about 30%, and the fluorescent lamp ballast accounts for about 15%.

Application

Silicon steel has high magnetic induction, which reduces the excitation current of the iron core and saves electric energy. The high magnetic induction of silicon steel enables the design of a high maximum magnetic induction (Bm), small size and light weight of the core, saving silicon steel, wires, insulation materials and structural materials, etc., which not only reduces the losses and manufacturing costs of motors and transformers, but also facilitates assembly and transportation.

Packaging & Shipping

silicon steel products needs to pay attention to moisture-proof and shock-proof during transportation. First of all, the packaging material should have a certain moisture-proof performance, such as the use of moisture-proof cardboard or the addition of moisture absorption agents; Secondly, in the process of packaging, the product should try to avoid direct contact with the ground and other hard objects, in order to prevent damage caused by vibration or extrusion during transportation.
