Abstract

A feature of the texture of a sheet hot rolled below Ar//3 is inhomogeneous formation through the thickness. In the case of Ti-added extra low carbon sheet steel, the recrystallization texture of the surface layer is characterized by a high intensity of Goss orientation. A calculation deriving r values from data of a three dimensional analysis shows that the surface layer deteriorates the deep drawability of the sheet. With the aid of a computer program calculating the strain distribution in the roll bite and a crystal rotation model the cause of the inhomogeneous texture formation has been studied. The calculation result shows that the surface texture is influenced by the friction between roll and sheet. With decreasing friction, the surface texture gradually becomes similar to that of the midplane.
