摘　　要：采用有限元软件ANSYS,结合某CSP生产线F4机架工作辊表面温度的实测值,建立轧辊二维温度场模型,对轧辊在轧制过程中的温度和热凸度变化进行研究。结果表明,轧辊在咬入弧区的换热系数为5.8×104 W/(m2·K),在非咬入弧区的水冷等效换热系数为1.1×104 W/(m2·K);在此等效换热边界条件下,使轧辊热凸度达到稳定的烫辊时间约为75min。Aided by the measured values of the surface temperature of F 4 work roll in a certain CSP line ,a two-dimension temperature field was established with ANSYS to study the temperature and thermal crown of the roll during the rolling process .The results show that the heat transfer coeffi-cient in the bite zone arc is 5 .8 ×104 W/（m2 · K ） ,the equivalent cooling coefficient in the non-bite zone arc is 1 .1 × 104 W/（m2 · K ） ,and on the condition of this equivalent heat transfer ,the hot roll time is about 75 minutes to make thermal crow n steady .
