| Abstract: | Based on the analysis of the effect of controlled rolling/controlled cooling process parameter changes on mierostructure and mechanical properties of X70 steel plate, many parameters such as the start rolling temperature, finish rolling temperature at finishing stand, and ACC which affect the microstructure and mechanical properties of X70 pipeline steel have been optimised. The results show that XT0 pipeline steel attains desired refined microstructure of acieular ferrite as majority and good mechanical properties. |
