Zusammenfassung:	The utility model relates to a heating device, and is especially applied to decarburization processing of finished protective slag in the field of steelmaking. The utility model discloses a decarburization device of protective slag, which comprises a furnace shell, a heating element and a protective slag sagger, wherein the protective slag sagger is installed in the furnace shell, the heating element is arranged at the lower part of the protective slag sagger, the protective slag sagger is provided with an air inlet and an air outlet, and the air inlet and the air outlet are communicated with the outside of a furnace body through pipelines which are not mutually communicated. In the utility model, a natural induced draft fan or a natural blower is adopted to insufflate air by arranging the air inlet and the air outlet so as to lead the air to be fully contacted with the protective slag and remove carbonaceous materials in the protective slag through oxidation; and the protective slag sagger can rotate along a
