The invention relates to the technical field of mineral smelting, and provides an exhaust method of smelted fused magnesite. The method comprises the following steps: an electrode introduced into a fused magnesite smelting furnace is made into a hollow structure which is perforated up and down; the internal diameter of the hollow structure is 1-10cm; the lower end of the hollow structure is a flared structure; the port of the flared structure with larger internal diameter is faced downwards; the height of the flared structure is 10-20cm; the internal diameter of the lower end port of the flared structure is 5-15cm; and the internal diameter of the upper end port of the flared structure is the same as the internal diameter of the hollow structure. The upper end of the hollow structure is communicated with an air duct of the smelting furnace through an insulation air duct. The method can improve the finished product quality of the smelted fused magnesite and enhance the safety of the smelting process.
