中文摘要：

以实验室模拟CSP连铸连轧工艺制备的热轧硅钢为基板,通过实验室常化、冷轧和初次再结晶退火实验,采用XRD和EBSD技术对样品从热轧到初次再结晶阶段的织构演变进行了研究。结果表明：GOSS晶粒起源于热轧的次表层,沿着次表层到中心层逐渐降低,热轧板中心层主要为{001}〈110〉织构。一次冷轧后,次表层存在强的{001}〈110〉和{112}〈110〉织构;1/4层存在强的{001}〈110〉和{112}〈110〉以及较强的{111}〈112〉织构;中心层则只存在强的{001}〈110〉织构。初次再结晶后,硅钢形成了强点{111}〈112〉织构的γ织构,GOSS织构再次出现,且分布在{111}〈112〉织构周围。GOSS晶粒周围以35°～55°大角度晶界为主,同时还有很高的Σ3和Σ5重合位置点阵。

英文摘要：

Taking hot rolled silicon steel prepared by CSP continuous casting and rolling process of the laboratory simulation as basilar plate, through laboratory normalization, cold rolling and primary recrystallization annealing experiments, the texture evolution of the sample from the hot rolling to the primary recrystallization was researched by using XRD and EBSD technique. The results show that： GOSS grains are originated from the subsurface of hot rolling and gradually decrease along the surface to the center layer. Hot rolled plate center layer is mainly {001 } 〈 110 〉 texture. After a cold rolling, strong {001} 〈 110 〉 and {112} 〈 110 〉 texture exist in subsurface; strong {001} 〈 110 〉 and {112} 〈 110 〉 texture as well as stronger { 111} 〈 112 〉 texture exist in 1/4 layer; strong {001 } 〈 110 〉 texture only exists in center layer. After primary recrystallization, the silicon steel forms γ/texture with the strong point of {111} 〈 112 〉 texture. GOSS texture appears again, and scatters around the {111} 〈 112 〉 texture. The large angle of 35° - 55° grain boundary is mainly around GOSS grains. At the same time, there are very high ∑3 and E5 coincidence site lattice.
