The Influence of Cold Rolling on the Microstructure for Drawing Steels
Abstract
The paper presents the structural changes that appeared in steel for deep drawing, as a result of cold rolling and of recrystallization thermal treatment. The research was conducted on samples taken from the rolled strap, treated and rerolled after the present technology in Arcelor Mittal. For comparison samples sampled from the steel strap before cold deforming (hot rolled) were used as blank tests. The thermal processing was done under industrial conditions in bell furnace. For the chosen steel the critical deformation degree was around the value of 6.5%.
