Electrical Steel Sheet
CRGO Joint Coil
CRGO Joint Coil is widely used to form transformer core, which is its main assembly. Abbreviated for cold rolled grain oriented coil, it is suitable for the applications where high amount of power is distributed and also in some audio output transformers. It is made from special type of steel, which has special magnetic properties having small hysteresis area which results in low power loss and high permeability. This coil is produced by cold rolling and is also utilized for manufacturing stator & rotor of electric motor.
CRGO Slit Coil
CRGO Slit Coil finds its application for distribution transformer, generator, steam turbines, water wheels, and ballast. Also known as electrical steel, it is highly appreciated for its saturation induction, good resistivity, magneto-crystalline anisotropy, and magnetostriction. Made from iron-silicon alloys, it is a soft magnetic material which is important for the production of energy saving electrical machines. This coil is made by secondary re-crystallization process which is done by accelerated growth of grains on already re-crystallized matrix.
Electrical Steel Sheet
Electrical Steel Sheet is made from iron alloy having about 6.5% silicone with small amounts of magnesium & aluminum. It is made in grain and non-grain oriented surface types that are specifically required for different purposes. This sheet has special magnetic properties, which make it suitable to be used for manufacturing of distribution transformer’s core and stator & rotor of electric motor. To assure its optimum performance, its magnetic property is checked by internationally followed Epstein frame method.
Electrical Steel Coils
Electrical Steel Coils are made from iron silicon based alloy with very low carbon content, having regularly oriented grains. They possess supreme electromagnetic properties, high insulation, and extreme strength. These coils are used in AC motors, audio & welding transformers, generators, and compressors. They can also be utilized for making magnetic switch cores, and ballasts. These coils are made by cold rolling from hot rolled coils having coated surface for increasing electrical resistance between laminations.
CRGO Coil is made of electrical grade steel which is suitable for making core of high power distribution transformers. Abbreviated for cold rolled grain oriented, it is known for low magnetic loss during operation due to its less hysteresis loop. The grains of this coil are larger and uniformly distributed over the surface as compared to normal steel. Manufacturing of this metal is done in a series of steps including hot rolled coil, pickling & cold rolling mill treatment, and final annealing & coating of insulating material.
