The numerical simulation and analysis on temperature field

stress-strain field and rolling force for <I)20 mm to 616. 5 mm 4 pass pre-finishing rolling process of steel 82B (/% : 0.79-0.86C

0.15-0.35Si

0.60 -0.90Mn

≤0.030S

≤0.030P) at steelworks are carried out by using nonlinear finite element method analysis software ABAQUS and an established 3-demensional thermo-mechanical coupling model between wire and roller. Results show that the simulated results conform to the measured results ； The difference between center temperature and surface temperature of stock during pre-finishing rolling process is 130 ℃ ； and with using this model to analyze front-sliding during rolling at worksite

it is obtained that main factors to influence the front-sliding are elongation coefficient

rolling groove size

rolling speed and ratio between roll diameter and stock thickness.
