Textural and magnetic properties of cross-rolled silicon steels

Abstract

Silicon steels are widely used for their electrical applications in motors, generators, small transformer cores due to their high permeability, low core losses and their uniform magnetic properties in all directions of the material. The major processing steps involved for the production of silicon steels are hot rolling, cold rolling and annealing. The processing steps largely affect the texture of these steels which subsequently improves the electrical properties of these steels. The objective of the present study is to investigate the cross-rolling effect on texture development of silicon steels and its magnetic/electrical properties. X- ray Diffraction (XRD) method is carried out on the sample to understand the textural development. PC based Pulse Field Hysteresis Loop Tester is used to estimate the magnetic properties. It is observed that the steels have improved textural and magnetic properties.
