This paper examines the magnetic properties of JFE Steel’s high silicon electrical steel sheets (Super Core series) as outstanding materials for high frequency reactors, which are important components for realizing energy saving in power equipment, and describes reactor performance when these materials were used in the reac-tor cores. 2.
Silicon is added to electrical steel sheets in order to increase their resistivity. In particular, because the eddy current loss in iron cores rises rapidly as the frequency increases, Si addition is extremely effective in improv-ing the high frequency magnetic properties of electrical steel sheets.
JFE Steel has developed two types of high silicon steel sheets suitable for high frequency applications, JFE Super Core “JNEX-Core” and “JNHF-Core.”
In particular, in the high frequency region, the new sheet possesses a low core loss property exceeding that of 6.5% Si steel sheets. As in the production of 6.5% Si steel sheets, this new magnetic gradient high Si steel sheet is produced by a process of siliconizing by CVD, followed by diffusion treatment using the continuous siliconizing line.
