Simulation Study of Deformation Zone Temperature Field for Ultra-high Strength Steel Thin Strip in Warm Rolling Process
The accurate prediction of the outlet temperature of deformation zone during the warm rolling process of ultra-high strength steel thin strip is the key to the rolling process formulation and process temperature control.Deform-3D simulation software was used to simulate the warm rolling process of ultra-high strength steel thin strip.The influences of the inlet temperature of the rolled piece,the surface temperature of the roll,the rolling speed,the reduction rate and the friction coefficient on the outlet temperature of the deformation zone were analyzed.The mathematical model of the t emperature field in the deformation zone was established by regression analysis.The results show that the temperature error between the calculation results of the mathematical model and the simulation results is within±11.5℃,and it can reflect the influence of various warm rolling process parameters on the outlet temperature of deformation zone.
