Dimension variation of heavy plate during quenching and tempering process

The implanted test with thermocouples during quenching process for a 60 kg grade steel was carried out,and the process was also simulated by ABAQUS software.The dimension variation trend of heavy plate during quenching process was investigated by testing the stress-stain curves.The results show that the software can simulate temperature variations of the steel during quenching process,thickness of the heavy plate decreases while the width and length increase during the quenching and tempering process.With the increasing of original thickness,the reduction ratio of thickness drops.Measurement of dimensions for the industrial produced heavy plate and comparison with the simulation show that the simulated varations of thickness and width are relative accurate,while the deviation of the length is slightly big.
