The pertinence of refining slag and inclusions is investigated as well as the influences of chemical composition, basicity and oxidizability of refining slag on size, morphology and category of inclusions in steel are analyzed based on the production process of rail steel. The results showed that the proportion of single particle inclusions with the size bigger than 50 μm decreased when the basicity of refining slag R was controlled at 2.0~2.5 and oxidizability of refining slag was controlled at about 0.6%.
