The oxidation behavior of typical low alloy high strength steel QStE500 TM and pressure vessel steel Q345 R during 2 250 mm hot continuous rolling was studied by oxidation kinetics experiment.The results show that the growth of iron oxide scale complies with the parabola law.The oxidation activation energy of QStE500 TM steel is 161.766 kJ/mol,and the oxidation activation energy of Q345 R is 179.179 kJ/mol.The iron oxide scale shows a typical three-layer iron oxide scale structure.When the oxidation temperature is in the range of 700～800 ℃,the oxidation rate is very slow and the iron oxide scale is thin.When the temperature is higher than 900 ℃,the oxidation rate and the thickness of iron oxide scale increase sharply.
