Lamination defects are commonly present inside steel plate,and they have a serious impact on the comprehensive properties of steel plate,in particular to the Z direction.Microstructure observation and microanalysis of lamination defects are carried out by using OM、SEM and EDS.Causes of common steel plate lamination defect are analyzed.The results show that the main cause of lamination defect include banded structure,mould powder,sulfide,folding,abnormal structure etc.Therefore,countermeasures for the processes like control of casting temperature and cooling rate,optimizing the process related to the mould powder,calcium treatment,stabe rolling and avoiding feed roll stalling are proposed together with appropriate quenching process.
