RESEARCH AND DEVELOPMENT OF LOW IRON LOSS HIGH MAGNETIC INDUCTIVITY NON-ORIENTED SILICON STEEL SERIES

The present paper has probed into the law about influences of test samples consisting of different elements such as Si, Mn, P, Sn, Sb, B and N and main down stream process parameters on the magnetic performance by way of orthogonal plan and in the meanwhile advanced a process plan including the main chemical compositions and process parameters for large scale production of low iron loss, high magnetic inductivity and non oriented silicon steel series particularly suitable for iron cores of small and medium sized high efficiency motors. The range of P 15/50 for this steel series is 4.00 to 8.00 W/kg and B 50 of this steel is 0.1T Gs hgher than that of the common brand silicon steel sheets.
