借助电子背散射衍射(EBSD)及ZEISS-200MAT金相显微镜对某钢厂普通取向硅钢(CGO)进行研究,研究结果表明:热轧板组织、织构沿板厚方向存在明显的不均匀性,在热轧板表层及次表层发生再结晶,同时存在强度较高的Goss织构,中心层存在较强的{001}<110>变形织构。冷轧组织均呈纤维状条带组织,一次冷轧后,热轧板中的Goss织构消失,织构主要为α、γ织构,经中间脱碳退火后,α、γ织构强度减弱,并出现一定强度的Goss织构和利于Goss织构发展的{554}<225>、{332}<113>等织构,经二次冷轧后,二次冷轧织构类型与一次冷轧织构一致,但织构强度不同。
The research of normal oriented silicon steel (CGO) in a steel mill was conducted by means of electron backscatter diffraction (EBSD) and ZEISS-200MAT metallographic microscope. The results show that there are obvious inhomogeneities along the thickness direction of the hot rolled plate, In the hot-rolled sheet surface and subsurface recrystallization, while there is a high strength Goss texture, there is a strong center {001} <110> deformation texture. The cold-rolled microstructure was fibrous ribbon structure. After a cold-rolling, the Goss texture in the hot-rolled sheet disappeared and the texture mainly consisted of α, γ texture. After decarburization annealing, the weakened α, γ texture , And a certain intensity of Goss textures and {554} <225>, {332} <113> textures that are conducive to the development of Goss textures are obtained. After secondary cold rolling, Rolling texture consistent, but different texture strength.
