Introduction
In order to meet the needs of punching and shearing processing when manufacturing appliances, silicon steel is also required to have a certain degree of plasticity.
In order to improve magnetic inductance performance and reduce hysteresis loss, the lower the content of harmful impurities in silicon steel, the better, and require a flat plate shape and good surface quality.
