摘要： 采用常规和异步轧制分别将0 3mm厚的成品取向硅钢板冷轧到0 10mm以下,然后在不同气氛的热处理炉中进行三次再结晶高温退火,研究同步、异步轧制条件下,热处理工艺参数(退火温度、保温时间、退火气氛、升温速度)对取向硅钢极薄带的磁性能和三次再结晶行为的影响·结果表明,相同的工艺参数下,真空退火的硅钢极薄带的磁性能优于氢气处理的;退火温度越高,保温时间越长,升温速度越快,磁性能越好,三次再结晶发展得越完善·

Abstract: The 0.3 mm commercial grain-oriented silicon steel sheets were rolled further under 0.1 mm in gauge by conventional rolling (CR) and cross shear rolling (CSR) separately, then the finished strips were annealed in furnace in different atmospheres for tertiary recrystallization. Effects of heat treatment parameters, such as annealing temperature, atmosphere, holding time and heating rate, on the magnetic properties and tertiary recrystallization behavior of the ultra-thin grain-oriented silicon steel strips were investigated. The results show that the magnetic properties achieved in vacuum are better than those in hydrogen atmosphere with other technological parameters kept the same, and the magnetic properties become higher with improved structure after tertiary recrystallization under conditions of higher annealing temperature, longer holding time, and higher heating rate.
