Abstract

The drawing properties of cold sheets rolled with CSP hot-bands (CSS) are not so good compared to cold sheets rolled with conventional hot bands (CSC). Therefore, influences of annealing technology on drawing properties of CSS have been studied in the paper. Research works included (1) drawing properties of cold sheets rolled with different CSP hot-bands, (2) drawing properties of CSS and CSS, and (3) influences of annealing technology on drawing properties of CSS. The results of annealing experiments, microstructural examinations and drawing property tests have shown that the drawing properties of CSS at higher finish deformation temperature (FDT) and lower coiling temperature (CT) are superior to those of CSS at lower FDT and higher CT. It was also found that the drawing properties of CSC are superior to those of CSS after heat treatment with same annealing technology. The annealing temperature for experimental steel grade (DC03) should be higher than 680°C.
