Abstract

The deep drawable cold sheets rolled with conventional hot bands and thin slab casting and rolling (TSCR) hot bands have different drawing properties. Samples of two kinds of cold sheets were taken in an automobile plant, and tests and analyses were conducted in chemical compositions, microstructures, cementite distributions and inclusion types etc. The investigation results have shown that the deterioration of drawing properties of cold sheets rolled with TSCR hot bands were caused by the differences in chemical composition, microstructure, cementite distribution and inclusion type. The suggestions are given to improve the drawing properties of TSCR hot-bands based cold sheets.
