摘　　要：在安钢1780热连轧机组上,用普碳钢成分生产出了抗拉强度和屈服强度分别达到500MPa和400MPa以上的超细晶粒热轧钢板,其显微组织为铁素体和珠光体,铁素体晶粒尺寸为5μm左右,热轧钢板各向异性小,具有良好的冷弯性能,实现了在安钢1780普通热连轧机上生产超细晶粒钢的技术创新。UItra-fine grain hot-rolled sheets were produced in 1780 hot rolling miII at Anyang SteeI,their composition is the same as Q235B,and the tensiIe strength and yieId strength are over 400MPa and 500MPa,the microstructures are ferrite and pearIite.Ferrite grain size is about 5μm.The anisotropy is sIight,coId-bending property is good.It is a technological innovation of using 1780 conventional hot rolling mill to produce ultra-fine grained steel in Anyang steel.
