Abstract��The transformation production and recrystallation for X70 pipeline steel has been carried out on the Gleeble��3800 simulating machine. Based on the schedule with two stages, multi��pass controlled rolling and moderate cooling rate was applied to hot rolling experiments, The effects of the technological parameters such as the refine start rolling temperature ,the finish rolling temperature, the cooling rate and the time on microstructure and mechanical property were analyzed. The result shows that the ideal volume fraction of the acicular ferrite would be obtained under good technological parameters.
