It has been found that the decomposition during heating and the precipitation during cooling start from 720 and 750℃ respectively. The shape and distribution of the precipitated carbides are markedly influenced by the cooling rate of the sheets after hot-rolling. If the cooling rate is high enough, saying up to 100℃/min, the carbides would be precipitated dispersely; while it slows down to about 1℃/min, they would be aggregated coarsely. The shape and distribution of the precipitated carbides are dependent on the efficiency of decarburization. In other words, the more disperse the carbide is, the more effective the decarburization will be. The results may provide leads for further improvement on the technology for hot-rolling Si-Fe sheet production. 收稿日期: 1984-06-18      服务 把本文推荐给朋友 加入引用管理器 E-mail Alert RSS 作者相关文章 罗阳 马黛 苏秀锦 李岫梅 孙立 王振琴 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1984/V20/I6/416 1 上海硅钢片厂,热轧硅钢片生产工艺改革,未发表资料,1980． 2 罗阳;马黛,钢铁18(1983) ,No.4,52． 3 Kissinger, H.
