摘要

通过Gleeble-3800热模拟试验机对AG650LW钢进行动态CCT曲线测定和轧制工艺模拟试验，得出满足650 MPa轮辋钢性能要求的组织为由铁素体+贝氏体+少量的珠光体，其终轧温度840～880℃

卷取温度480℃

轧后层流冷却速率≥10℃/s

硬度≥220HV。试验钢卷的综合开裂率4.3‰

满足了用户的加工期望要求。

Abstract

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%

which meets the requirement of the user.
