【摘要】 为研究退火工艺对普通取向硅钢初次再结晶组织的影响,对经不同温度、保温时间和升温速率退火后的材料组织进行了分析。结果表明:在等温退火条件下,加热至600℃时开始发生初次再结晶,800℃以上初次再结晶组织发展完善;而在最终冷轧板直接进行最终高温退火的情况下,加热温度在500~700℃时,将升温速率提高到80℃/h,初次再结晶组织更易于发展完善。
【Abstract】 To investigate the influence of annealing process on the recrystallization of common grain oriented silicon steel,microstructures of sheets annealed at different temperature,soaking time and heating rate are observed.Results show that under the condition of isothermal annealing,recrystallization begins at 600℃ and fully develops above 800℃,while in the case that the final cold rolled sheets are directly thrown to final high temperature annealing,recrystallization is likely to develop with the he…
