【摘要】 研究了薄板坯连铸连轧流程(TSCR)条件下热轧工艺对3.2%Si-0.7%Al无取向硅钢组织、织构演变及磁性能的影响规律。结果表明,提高均热温度和热轧温度有助于获得粗大的变形组织和强烈的{001}〈110〉织构,进而对后续的组织、织构演变进程及磁性能产生有利的遗传影响。与低温均热和低温热轧相比,高温均热和高温热轧得到的最终成品板的再结晶晶粒较粗大,λ纤维再结晶织构较强而γ纤维再结晶织构较弱,磁感应强度较高。
【Abstract】 It was investigated that the effects of thin slab cast rolling(TSCR) hot rolling processes on microstructural,textural evolution and magnetic properties of 3.2%Si-0.7%Al non-oriented silicon steel.The results show that much larger hot rolling deformed microstructure and much stronger {001}〈110〉 texture could be obtained by increasing the soaking and hot rolling temperatures,which had good heritable effects on subsequent microstructural,textural evolution and magnetic properties.The final sheets …
