Study of Microstructure and Texture of Cold Rolled Grain Oriented Electrical Steels

Abstract

Silicon steel is known as electrical steel and it is extensively used for electrical applications such as preferred core material for equipment like transformer cores, motors, and generators. There are two types of electrical steels namely cold rolled grain oriented and cold rolled non grain oriented electrical steels. The properties required for these steels are a high perme-ability and high magnetic induction, low magnetic losses (watt losses), and low magnetostriction. The factors like high permeability and induction is effective in reducing the size and weight of the parts thus increases the effi-ciency; low magnetic losses reduce the generation of heat and energy consumption thus helps in minimizing energy; and a low magnetostriction reduces the noise in transfor-mers and high capacity machines helps in producing less humming sound.
