Abstract：300~500m SiCa lines were injected with speeds of 100m/min and 200m/min or SiCaBaFe alloy was fed into liquid steel to modify the inclusions in the later stage of LF refining of X70 respectively. Samples were taken from molten steel in ladle after injection, molten steel in the mould and slab. The investigation of the CaTot and inclusions shows that: the calcium content in the steel drops after the calcium treatment; the compositions, morphology and sizes of the inclusions varies with the production. Rules for inclusion modification was put forward according to the variation of inclusions and influence of inclusions on the properties of the high grad pipelines and casting.
