Effect of Ferrite Rolling Process on Texture of Ultra Deep Drawing Steel

In this study,the effect of process parameters on the varieties and evolution of texture during rolling process were investigated by controlling the rough rolling temperature,finish rolling temperature and the thickness of finished products.The result shows that as the rough rolling temperature declines from 923 ℃ to 855 ℃,the intensity of { 111} ∥ND texture increases.Besides,when the finish rolling temperature declines from 810 ℃ to 791 ℃,the intensity of the unfavorable { 113} ＜ 110 ＞ texture is markedly weakened.All of these adjustments benefit to the good performance of ultimate sheet.when the thickness of finished products is reduced from 4.0 mm to 3.0 mm,the responding annealed cold-rolled sheet have a increasing r vaule with r₉₀ exceeding 3.2 and |Δr| as low as 0.08.
