CONTINUOUS SILICONIZING TECHNOLOGY OF 6.5 -PERCENT SILICON STEEL SHEET

It is wellknown that 6.5% Si steel has excellent soft magnetic propert ies, but high Si steel more than 4% Si are so brittle that it is impos sible to manufacture thin gauge steel sheets using the conventional ro lling process. Using the siliconizing method, we have succeeded in dev eloping the world's first non-oriented 6.5% Si steel sheets for commer cial production in coil form, with a thickness range 0.1-0.5 mm. The 6 .5% Si steel sheets have no void and exhibit excellent soft magnetic p roperties, a high frequency core loss W10/400 of 9.9 W/kg for a thickn ess of 0.3mm. In addition, the product has good workability.
