Recent Progress on High Magnetic Induction Grain-Oriented Silicon Steel Sheets in Japan(Ⅱ)

收集整理日本2004年度硅钢专利文献152项,其中高磁感Hi-B取向硅钢专利文献34项。Hi-B钢最新技术涉及诸多方面,本文对开发高温退火隔离剂,改善最终高温退火工艺,无铬薄膜的形成方法,改善薄膜质量进行了分析、研究,以供借鉴。

152 items of silicon steels patent bibliography in 2004 in Japan are collected and sorted out, in which 34 items are high magnetic induction grain-oriented silicon steel sheets patent bibliography. For Hi-B silicon steels, recent technology includes a lot of aspects, this paper analyzed and explored on the development of new high-temperature annealing segregator, ultimate high-temperature annealing process improvement thin film chrome-less forming method and upgrade thin film.
