| Abstract: | In 1985~2005, the patents of non-oriented electrical steel applied in China consist of 44 patents applied by abroad producers (main producers were JFE and Shin Nippon Seitetsu) and 48 patents applied by native producers (main producers were Baosteel and Wuhan Steel). The fields of patented technology of electrical steel applied by abroad producers mainly include high efficiency and painting technology, and that applied by native producers mainly include rolling process and painting technology. The typical patented technology of non-oriented electrical steel including high efficiency, thin strip casting, painting, shaping process and semi-process products is presented. The developed trend of non-oriented electrical steel is high efficiency production and special service products. |
