Abstract：In order to study the influence of the main process parameters on the oxide scale of hot rolled strip， the nidustry experiment was carried out on the basis of CSP production line. The results show that the thickness of the strip has an important influence on the thickness of the oxide scale，and the thickness of oxide scale is unevenly distributed along the width of the stripdue to the difference of oxygen supply. By adjusting the final rolling temperature and laminar cooling method，the thickness of oxide scale can be reduced，but the effect is not obvious. Decreasing the coiling temperature is beneficial to promote the occurrence of eutectoid reaction of FeO，increase the ratio of α-Fe+Fe3O4，and improve the adhesion of oxide scale at room temperature. The distribution of oxide scales in the width of strip is uneven，and the eutectoid reaction of FeO in the middle is more adequate.
