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。
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~ A1 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 fabricated at higher soaking and hot rolling temperatures possessed much larger recrystallization grains, relatively stronger γ-fiber and weaker γ-fiber recrystallization texture and higher magnetic induction.
