Good Performance of Insulating Film Silicon Steel Sheet

Breif Introduction

Silicon Steel Sheet is steel with silicon added to it. The addition of silicon to steel increases its electrical resistance, improves the magnetic flux strength, and reduces the steel’s hysteresis loss. Hysteresis is the lag between the times when a magnetic field is first generated or applied to the steel and when the field fully develops. Through control of the grain size, the hysteresis loss of the steel can be accurately controlled. The direction of the grain in Silicon Steel can also affect its efficiency. The grain can be oriented in one or double direction (CRGO) through rolling to improve its density or the grain can be non-oriented and run in all directions (CRNGO), making the Silicon Steel less expensive.
