FEM research on nose/agio shape control of slab during heavy plate rolling
By using ABAQUS FEM software,the heavy plate rolling processing was simulated to investigate the factors which could have great influence on the slab shape.The factors mainly include rolling center-line position(Hi),the rotation speed difference between the rolls(Ski),and temperature difference between the upper and bottom surfaces of the slab(ΔT).These factors could have different effects on the slab shape(nose or agio).The simulation results show that Hi,Ski andΔT could have-17.5 mm,-181.0 mm and-200.0 mm influences on shape in a 2 m-long slab,respectively.Furthermore,through adjusting Ski and controlling ΔT,the slab shape could be adjusted more sufficiently than that of adjusting the rolling center-line position Hi.The commercial experiment shows that through controlling ΔT,nose/agio shape control could be more effective.
