The invention discloses an electroslag remelting method for stabilizing a titanium element, which comprises the following steps: controlling the titanium content of a consumable electrode to be above the upper limit of a target component of an electroslag blank, and controlling the titanium content to exceed the upper limit of the target component by 10%-20%; coating operation is conducted on the consumable electrode subjected to surface treatment, and a coating sequentially comprises an aluminum powder layer and/or a titanium dioxide layer and an emery powder layer from inside to outside; in the electroslag remelting stage, electroslag materials are added into the crystallizer, the average thickness of a slag pool is controlled to be 1/3-1/2 of the equivalent diameter of a smelted consumable electrode, and meanwhile inert gas is blown into the crystallizer; and in the feeding stage, the electroslag material is added into the crystallizer again, the thickness of the slag pool is controlled to be 1/2-1.0 of th
