Zusammenfassung:	PROBLEM TO BE SOLVED: To obtain an additive for steel refining excellent in the balance to high desulfurization, high safety and non-erosiveness of a furnace lining, or the like, by preparing the additive for steel refining containing specifized ratios of CaO, CaCN2 and the other inorganic materials and composed of a specified range of granular material. SOLUTION: The additive for steel refining containing 10-90 wt.% CaO, 3-70 wt.% CaCN2 and 5-70 wt.% inorganic materials except CaO and CaCN2 and composed of the granular material having
