The dynamic CCT curve measurement and rolling process simulation test of AG650LW steel are carried out by gleeble-3800.It is obtained that the structure to satisfy 650 MPa rim steel is ferrite + bainite + a small amount of pearlite
with end rolling temperature at 840~880 ℃and coiling temperature at 480 ℃
laminar flow cooling rate after rolling≥ 10 ℃/s
and hardness value≥220HV.The comprehensive crack ratio of the test coil is 4.3%
