Abstract: Steels alloyed with Si and Al are used as core material in flux carrying machines, they are commonly called electrical steels, divided into grain oriented and non-oriented when a material without magnetic anisotropy or not is desired and used in transformer and electrical motors, respectively.

Hot-rolled wide strip. Hot-rolled steel strip with a width of >600 mm that is rolled directly from slabs in a semi- or completely continuous hot strip mill or - in the case of pure stainless products - in separate Steckel mills. Hot-rolled strips can be used for specific applications and especially as starting material for the cold-rolling process.

Specifications Non-oriented Silicon Steel: Non-oriented Silicon Steel is known as CRNGO, it is Electrical steel made without special processing to control crystal orientation, non-oriented steel, usually has a silicon level of 2 to 3.5% and has similar magnetic properties in all directions, i.e., it is isotropic.Cold-rolled non-grain-oriented steel is often abbreviated to CRNGO (Wiki ...

Dec 25, 2020 · The addition of silicon to steel increases its electrical resistance, improves the ability of magnetic fields to penetrate it, and reduces the steel’s hysteresis loss. This type of steel is used in many electrical applications where electromagnetic fields are important, such as in transformers, magnetic coils and electrical motors.

A transformer's core is manufactured from laminations of silicon iron, although it is generally referred to as silicon 'steel'. Silicon iron is used because it offers low hysteresis losses and has ...

Electrical steel explained. Electrical steel (lamination steel, silicon electrical steel, silicon steel, relay steel, transformer steel) is an iron alloy tailored to produce specific magnetic properties: small hysteresis area resulting in low power loss per cycle, low core loss, and high permeability.. Electrical steel is usually manufactured in cold-rolled strips less than 2 mm thick.

Transformer stamping – silicon steel. Permanent magnet – hard magnetic material (Al, Ni, Co) 5. Comment on the use of CRGOS strip wound transformer core. CRGOS means cold rolled grain oriented steel. This steel is manufactured by series of cold reductions and intermediate annealings.

Cold rolled grain oriented silicon steel (3%) i.e. CRGO is used for core material of protective CT. This material has high permeability, high saturation level and small magnetizing current. For very high value of fault currents nickel-iron alloy material is used for core.
