Effect of hot rolling conditions to produce deep drawing quality steels for continuous annealing process

Most of cold rolled deep drawability steel sheets finds application in areas where forming is critical. Deep drawing sheet steel requires good mechanical properties and microstructures, as well as sufficient anti-aging characteristics. Therefore, deep drawing steels are produced by controlling these metallurgical factors and optimizing steelmaking, hot rolling, cold rolling and annealing processes. This paper explains the effect the microstructure and mechanical properties of hot rolling conditions on continuously annealed sheet properties in certain chemical composition. Experiments have been conducted to investigate the effect of hot rolling conditions. Consequently, it became clear that hot rolling conditions play an important role in producing continuous annealed deep drawing quality steels.
