ELECTRICAL STEEL : Electrical Steel, also called lamination steel, silicon electrical steel, silicon steel or transformer steel is speciality steel tailored to produce certain magnetic poperties, such as small hysteresis area (small energy dissipation per cycle, or low core loss) and high permeability.
PRODUCTION PROCESS
1) Hot Rolled Coil-> Pre-Annealing and Pickling -> High Temperature Annealing -> Insulation Coating -> PH-Core & PG-Core
2) Hot Rolled Coil-> Pickling -> Cold Rolling -> Annealing -> Tempreture Rollling -> Insulation Coating -> PN- Core & PNS Core
1) CRGO: Core laminations are the main part of an electrical transformer, and this attribute to 70% of a transformer cost. These core laminations are required to be cut from special steel called as Cold Rolled Grain Oriented Electrical Steel or popularly known as CRGO. The CRGO is a special quality of steel which have a special grain surface and comes in a thickness of 0.23 mm, 0.27 mm, 0.30 mm, 0.35 mm. (generally called M3, M4, M5 & M6). Lower the thickness of material better is the quality of material.
