It was Shown that by the slab reheated under an exceedingly high temperature,the hot rolled band of large elongated grain structure may be produced, and its {100}<011>-<001> components in the primary recrystallization texture enhanced.In these regions the primaries are enlarged and the lined grain structure is appeared after final annealing, while the slab reheated under lower temperature, the product in which the solution of the MnS and A1N has not be completed yet,may be obtained with mixed grain structure. In addition, it is presented that the lined fine grain structure could be reduced or prevented by increasing carbon content of the steel, by raising hot reduction or by adopting two stages in cold rolled process. 收稿日期: 1981-04-18      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 李军 陈煜廉 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1981/V17/I4/441 [1] Regits, L.
