在本钢薄板坯连铸连轧生产线上进行了X60管线钢的试制。结果表明,成分为铌、钒、钛复合微合金化的低碳锰钢采用合适的控轧控冷工艺,可以保证钢的力学性能符合X60管线钢的要求。试制钢具有优良的强度和塑性配合,并具有很好的低温韧性水平。试制钢的显微组织为铁素体和珠光体,平均晶粒尺寸细小,铁素体、珠光体分布均匀,没有明显带状组织。 In the Benxi thin slab casting and rolling production line X60 pipeline steel trial. The results show that the suitable controlled rolling and controlled cooling process for the low carbon manganese steel with the composition of niobium, vanadium and titanium composite microalloyed can ensure the mechanical properties of the steel meet the requirements of X60 pipeline steel. Trial steel has excellent strength and plasticity, and has good low temperature toughness level. The microstructure of trial steel is ferrite and pearlite, the average grain size is small, ferrite and pearlite are evenly distributed, and there is no obvious banded structure.
