The utility model relates to an interface structure of a dedusting pipeline of an electric furnace for steelmaking, which comprises a ladle cover side smoke hood connected with a ladle cover of an electric furnace body, a movable flue and a fixed flue, and is characterized in that the end surface of an interface between the ladle cover side smoke hood and the movable flue forms a certain included angle with an axial line, the movable flue is mounted on the fixed flue, a slideway is arranged on the inner wall of the movable flue, the slideway is matched with a track arranged on the outer side of the fixed flue, and a spring mechanism is arranged between the fixed flue and the movable flue, so that the movable flue has pre-pressing force after the ladle cover side smoke hood is closely combined with the movable flue. Due to the adoption of an oblique end surface in the structure, when in operation and rotation of the ladle cover of the electric furnace, the rotation operation can be performed without moving the
