説明

Residual stresses in the steel sheet specimens cold-rolled from 20 to 67% total sectional reductions were measured. Used specimens were hot-rolled sheets which had the thickness of 5.0 and 3.2 mm. In cold-rolling, two different roll sizes, 250 and 75 mm in diameter, were used and the reduction per pass was 20%. Textures in the sections of these specimens were measured. Normal residual stresses along the rolling and transverse directions are tension in the outer parts and compression in the inner parts of these specimens, and the residual stresses in the surface is compression in the case of the rolling condition with large diameter rolls. On the residual stress distribution in the specimens rolled with large diameter rolls, the effect of the residual stress existing before rolling vanished over 40% reduction, and the same tendencies were observed in the specimens by heavy reductions. The residual stress distribution in the sheet after rolling by large diameter rolls differ from the one by small diameter rolls. The residual shearing stresses in the section of these specimens vary depending on the increasing reduction. The influence of the structure for the generation of residual stress on rolling was discussed.
