Effects of pulse electric fields on the magnetic properties and texture of oriented silicon steel

An automatic measurement system for silicon steel and an X-ray diffraction meter were used for measuring the magnetic property parameters and texture of ex-processed samples and processed samples.It is shown that under the condition of a lower voltage,9Hz,a longer processed time and an annealing temperature of 650℃,the decrease rate of iron loss can be increased;a lower voltage,a higher frequency and an annealing temperature of 650℃ are in favor of improving the increase rate of magnetic induction.The best test parameters for improving the magnetic properties are the frequency of 9Hz,the voltage of 500V,the processing time of 6min and the annealing temperature of 650℃.Through texture analysis,it is verified that the change in magnetic induction of oriented silicon steel depends on the 110 001 orientation degree and the 110 001 orientation degree can be regarded as a comprehensive value which reflects the situation of the overall average angle of divergence.
