Texture of Hot Rolled Strip for Fe-3Si Steel Produced by Thin Slab Casting and Rolling

Abstract

Abstract Fe-3Si steel strip was produced by thin slab casting and rolling (TSCR) process in the laboratory. The microstructure and texture of hot rolled strip by different total reduction and rolling schedules were observed through EBSD technique and X-ray diffraction method. The rule of texture density for the α, ɛ and γ fibers was analyzed. When the total reduction was increased from 82. 9 % to 97. 1 %, the gradient of microstructure and texture for A steel surface layer and center layer was found, {001}<1 ▪0> texture had higher intensity, and {001}<1 ▪0> texture was changed to {110}<001> and {112}<111>. The texture distribution with different reduction schedules for B steel was basically similar, but the Goss texture orientation density and volume fraction for B steel were higher, the hot rolling reduction schedule of C1 was effective for the formation of Goss texture. The research work was useful theoretical basis and reference data to develop electrical steel by thin slab continuous casting and direct rolling technology.
