在取向电工钢中添加不同含量的合金元素钒,并通过铁损P17和磁感风的测试与分析,研究了钒对取向电工钢磁性能的影响,发现:随钒含量从0增大至0.022％,取向电工钢的平均晶粒尺寸和铁损P17先减小后增大、织构等级和磁感最先增大后减小、磁性能先提高后下降.钒含量超过0.020％将恶化取向电工钢的磁性能.取向电工钢中钒含量优选为0.008％,较未添加钒相比铁损平均晶粒尺寸减小14.29％、织构等级增大267.15％、P17减小15.32％、磁感B8增大13.09％.
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 O.000％ to O.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.
