Effect of Vanadium on the Magnetic Properties of Oriented Electric Steel

The effect of vanadium on the magnetic properties of oriented electric steel was studied by testing and analyzing the iron loss P₁₇ and magnetic induction B₈ of the samples,with adding different content of vanadium in oriented electric steels.The results show that the average grain size and the iron loss P₁₇ of the oriented electric steel first decrease then increase while the texture grade and magnetic induction B₈ of the steel first increase then decrease with the magnetic properties of the steel improved first then declined,when the content of vanadium increases from 0.000% to 0.022%.The magnetic properties of the oriented electric steel will be deteriorated with more than 0.020% of vanadium content.The content of vanadium was optimized at 0.008%,and the average grain size and the iron loss P₁₇ of the steel respectively decreased by 14.29% and 15.32% while the texture grade and magnetic induction B₈ of the steel separately increased by 267.15% and 13.09%,comparing with those of vanadium-absence steel.
