EFFECT OF CHEMICAL COMPOSITION AND PROCESSES ON THE TEXTURE OF HOT-ROLLED DEEP DRAWING STEEL SHEET

A hot-rolled deep drawing (HDD) steel with high r-value and uniform distribution of{ 111} texture in thickness was developed by hot rolling in ferrite region with lubricatingbetween the roller and the steel. The experimental results show that the carbon contentand finish rolling temperature have significant effects on beneficial texture {111}, andlubricating during hot rolling at low temperature in α-region makes the distributionof the texture uniform. Three basic requirements needed to meet for HDD steel wereconcluded by comparing different carbon contents and hot rolling processes.
