Abstract
We describe the effect of varying tension leveling parameters on the microstructure and mechanical properties of steel strips. We found that, when the tension leveling elongation was constant, an increase in the screw-down value resulted in an initial decrease in the cross-sectional grain size of the strip, which was followed by an increase. However, the longitudinal grain size remained constant, and the yield strength and tensile strength increased gradually. In addition, with a constant screw-down value, an increase in tension leveling elongation resulted in refining of the cross-sectional grain size, elongation of the longitudinal grain size, and small increases in both yield and tensile strength. This study therefore provides an insight into the optimal configuration of tension leveling parameters to improve steel strip properties.
