To investigate effects of inclusions modification in steel,the morphology and composition distribution of inclusions in liquid steel from tundish,and composition changes of molten steel in the production of oil casing steel by BOF→LF→RH→CC flow of three different calcium treatment routes were observed.It is found out that the composition changes of molten steel,and the morphology and composition distribution of inclusions in liquid steel from tundish has significant difference due to different calcium treatment routes.In order to select the optimum route,the effects of calcium treatment are evaluated by modification index of inclusions,and the advantages and disadvantages of different calcium treatment routes are considered.
