Silicon steel sheet
Classification :
Carbon steel plate
PRODUCT DETAILS
Product Description
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

Production Process
1. Pickling: Use a descaling machine and a hydrochloric acid tank to remove oxides from the hot-rolled steel strip to prevent surface defects of the cold-rolled finished product.
2. Cold stamping: In order to ensure the thickness and material for different uses, the deceleration ratio is set to 40%-90%, and advanced control equipment such as automatic thickness control and automatic shape control are implemented.
3. Annealing: It is a process to soften the steel strip material that has been hardened in the cold stamping process. Through metal heating and rapid cooling, we produce steel for deep processing and high-tensile strength steel, and adopt boxing (hood annealing) annealing and continuous annealing methods.
4. Insulating coating: When processing the silicon steel plate into an iron core, in order to improve its processing performance and prevent the loss of eddy current equivalent to the thickness of the steel plate, continuous coating equipment is used to spray the insulating coating liquid on the upper and lower sides of the steel plate
