Influence of texture pretreatment on cold rolling texture of ELC-BH sheet

In order to further investigate how cold rolling texture is produced in an extra low-carbon and high strength bake-hardening sheet steel (for short, hereafter, coiled ELC-BH sheet) with r value as high as 2.67, texture change in texture pretreatment and its effects on the cold rolling texture are researched by means of Orientation Distribution Funchon (ODf) method. Experimental results show that the cold rolling texture which Produces very strong {111} annealing texture actually is caused by texture change in the texture pretreatment, and the strong {111} texture obtained rough this texture pretreatment is an essential condition of engendering the cold rolling texture, while the stability of {111} texture components in cold rolling is a sufficient condition of emerging thes one.
