Effects of a new technology which made r¯-value increase remarkably on the distributions of the cold rolling and annealing textures through the thickness of an extra low-carbon and high strength bake-hardening sheet steel have been researched by means of the method of ODF. The results are expressed as follows: (1) γ-fiber axis texture in the ELC-BH sheet obtained by the new technology develops so strongly and purely, especially within the sheet. This is the essential cause why r¯-value of the sheet remarkably increases. (2) The very strong γ-fiber axis texture of being completely different from conventional one is closely related to the cold rolled sheet supplied by the new technology which benefits to develop {111} annealing texture strongly. The inside of the cold rolled sheet is far more favorable than its surface to the development of the γ-fiber axis texture.
