Research and Application of High Temperature Deformation Resistance in Low-alloy Steel with Vanadium

By the MMS-200 testing machine for thermal simulation,researched the deformation resistance in 850~1 100 ℃ temperature for vanadium low-alloy steel whose tensile strength is 510 MPa and analyzed deformation temperature,deformation speed and deformation extent to influence the deformation resistance in the test.According to the experimental result,the mathematical model of deformation resistance in hot continuous rolling has been optimized and improved.The prediction error for rolling force is reduced from 8%~10% to below 5%.The prediction accuracy of the mathematical model for process control has been improved effectively.
