摘　　要：在实验室条件下采用薄板坯连铸连轧工艺制备了Fe-3%Si热轧钢板,采用EBSD和X射线衍射仪分析了不同热轧总变形量和压下制度下钢板的织构组织,分析了α、ε和γ取向线上织构密度的变化规律。结果表明:热轧总变形量由82.9%增大到97.1%时,A成分钢板表层和心部的组织和织构梯度出现,{001}〈110〉取向加强,并向{110}〈001〉和{112}〈111〉等方向发展;B成分钢板在不同压下制度下的织构分布基本相同,但是B1试样的高斯织构取向密度和体积分数较高,C1热轧压下制度有利于高斯织构组织的形成。Hot rolled Fe-3%Si steel plate was produced by thin slab continuons casting and rolling process in laboratory.The microstructure and texture of hot rolled plates with different total reductions and rolling schedules were analyzed using EBSD and X-ray diffraction.The change rule of the texture density along α,ε and γ fibers was analyzed.The results show that when the hot rolled total reduction increased from 82.9% to 97.1%,the gradient of microstructure and texture for the plate with A composition occured at the surface and center,{001}〈110〉 orientation was strengthened,and then changed to {110}〈001〉 and {112}〈111〉.The texture distribution with different reduction schedules for plate with B composition was basically similar,while the Goss texture orientation density and volume fraction for sample B1 were higher.The hot rolling reduction schedule of C1 was effective to the formation of Goss texture.
