High Electric Resistance Silicon Steel Lamination For Motors And Transformers - China

1、 Brief Introduction for Silicon Steel Coil/ Sheet

( 1) Silicon Steel Coil/ Sheet, often called Electrical Steel Coil, 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.

The addition of silicon to steel makes the steel more

efficient and faster in terms of building and maintaining magnetic fields.

Thus, Silicon Steel Coil/ Sheet improves the efficiency and effectiveness of

any device using steel as a magnetic core material.

( 2) The percentage of silicon added to Silicon Steel Coil/ Sheet varies with

its intended use up to 6.5 percent.

For some items, such as high- efficiency

motors and transformers, silicon comprises approximately 3 percent of the

steel’s makeup.

In other items requiring less efficiency, such as certain

types of motor applications, the amount of silicon can be as low as 2 percent.

Though expensive when compared to regular carbon steel, Silicon Steel Coil/

Sheet can be produced with whatever percentage of silicon needed for a

specific application.

( 3) Silicon Steel Coil/ Sheet is produced in strips or rolls, cut into the

needed shapes and then heat- treated to control the size of the grain of the

steel.

Through control of the grain size, the hysteresis loss of the steel can

be accurately controlled.

The direction of the grain in Silicon Steel Coil/

Sheet can also affect its efficiency.

The grain can be oriented in one or

double direction ( CRGO Silicon Steel Coil/ Sheet) through rolling to improve

its density or the grain can be non- oriented and run in all directions (

CRNGO Silicon Steel Coil/ Sheet) , making the Silicon Steel Coil/ Sheet less

expensive.

( 4) Once the heat- treating process is completed, Silicon Steel Coil/ Sheet

is often coated or varnished, to further retard corrosion, then stacked to the

needed thicknesses.

These thicknesses are called laminations, and they may, or

may not, be physically attached or bonded to one another.

These stacked

laminations serve as the cores of almost all electromagnetic devices in modern

use, such as in transformers, magnetic coils and electrical motors.
