This paper presents a general survey of roles and progress of fundamental and functional refractories applied in secondary steelmaking, tundish and mold metallurgy along with the evolution of clean steel technology,focusing on refractories that are to create clean environments, benefit cleanliness and productive efficiency for the clean steal production, in particular, reducing the total oxygen content and inclusion defects in steel. All that arguments have revealed in abundant that the interaction between the clean steel technology and innovation of refractories is so intimate that the philosophy of clean steel technology would not be accomplished without functioning of the innovated state of the arts refractories in it.
