摘　　要：根据新日铁、JFE及浦项等国外钢铁公司2008年以来在日本专利局、欧洲专利局(EP)及世界知识产权组织(WIPO)申请公开的有关生产Hi-B取向电工钢典型专利技术,概述了近年来国外大型钢铁企业采用低温板坯加热(坯加热温度<1 280℃)技术生产Hi-B取向电工钢主要技术重点,即将调节关键化学成分Al、N、Sn及Sb等与工艺改进相结合。最后介绍了国外大型钢铁企业采用低温板坯加热技术生产Hi-B取向电工钢实例。The latest developments on technology for manufacturing Hi-B grain oriented electrical steel sheets developed by Nippon Steel Corp., JFE Steel and POSCO were described according to the patents published by World Intellectual Property Organization, Japan Patent Office and European Patent Office over the recent years. The low temperature slab heating process （particularly slab-heating temperature 〈 1 280 ℃ ） together with suitably adjusting key chemical elements such as A1, N, Sn and Sb elements was the key point of this technical development. The production reality of Hi-B grain oriented electrical steel sheets in some large size iron and steel enterprises abroad was introduced.
