METHOD FOR MANUFACTURING A HIGH SILICON ELECTRIC STEEL SHEET FOR HAVING THE EXCELLENT ELECTRONIC PROPERTIES BY CONTAINING THE HIGH CONTENT OF SILICON, AND A SYSTEM FOR MANUFACTURING THE ELECTRIC STEEL SHEET

摘要

PURPOSE: A method for manufacturing a high silicon electric steel sheet and a system for manufacturing the electric steel sheet are provided to contain the high content of silicon, and to economically manufacture a second steel plate with the thin thickness.;CONSTITUTION: A method for manufacturing a electric steel sheet comprises the following the steps: providing a first steel plate (50); forming at least one silicon layer on at least one surface of the first steel plate by using a plasma chemical vapor deposition method; and forming a second steel plate (60) containing silicon by heat-treating the first steel plate so that the silicon of at least one silicon layer is diffused in the first steel plate. The first steel plate contains 0 to 4 wt% of the first silicon content, and the second steel plate contains 5.5 to 7.5 wt% of the second silicon content.;COPYRIGHT KIPO 2013
