Abstract

Abstract

The effect of hot continuous rolling-cold rolling-annealing process on microstructure and texture of 50W1300 non-oriented silicon steel is investigated by the technology of EBSD and electron microscopy.The results show that during thermoplastic processing,all the grains in the surface layer of hot-rolled plates are equiaxed crystal and the grains in their cores are deformed flattened structure.The hot-rolled microstructure is transformed to flattened banded structure with characteristics of fibrous structure in the core after cold rolling.The annealed structure is composed of equiaxed ferrite grains with distinct and regular boundary.The texture distribution of hot rolled plates along the thickness are different while texture of cold rolled plate are basically the same,mainly consisting of α texture,γ texture and rotated cube texture of {100} ＜110＞.At the 1/4 thickness of the plate,the strength of α texture and rotated cube texture reaches the highest level while the strength of the γ texture decreases remarkably.The strength of γ-texture is weakened to some extent in the annealed plates.
