用于从硅钢生产热轧钢带的工艺和装置

PROCESS AND DEVICE FOR PRODUCING HOT-ROLLED STRIP FROM SILICON STEEL
摘要：
A method and a combined casting/rolling installation for production/processing of high-quality hot-rolled strip into grain-oriented electrical steel strip at low cost, provides for: a) melting a steel having a chemical composition in wt % of Si 2 to 7%, C 0.01 to 0.1%, Mn 30% or the total true strain of all passes is >50%; d) heating the strip to a final temperature of 1050 to 1250° C., preferably 1100 to 1180° C.; e) finish rolling the strip in a second rolling train, then f) cooling and winding the strip.
摘要（中）：

一种用于以低成本生产/加工高质量热轧钢带的方法和组合铸造/轧制装置，其提供：a）将具有化学组成的化学组成为Si 2的重量％的钢熔化 至0.01％，S <0.05％，Al <0.09％，Cr <0.3％，N <0.02％，P <0.1％，C为0.01〜0.1％，Mn为0.3％，Cu为0.1〜 ，余量为Fe和杂质; b）在连续铸造设备上铸造具有25至150mm厚度的线材; c）在铸造线材之后直接轧制至多达4个轧制道次，其中至少在一个轧制道次中真实应变为> 30％，或者所有道次的总真实应变为> 50％; d）将条加热至最终温度1050至1250℃，优选1100至1180℃; e）在第二个轧制列车中完成轧制，然后f）冷却和卷绕带材。
