Claims

[Scope of utility model registration request]

Insert the electrode into the electrode insertion hole opened in the ceiling of the furnace cover,
In a steelmaking furnace in which raw materials are melted by a discharge arc caused by this electrode, the water-cooled furnace has at least one concave portion formed in an annular shape surrounding the electrode on the upper surface of the periphery of the electrode insertion hole of the furnace cover in the circumferential direction of the inner circumferential surface. A jacket is fixedly installed, a sealing material made of a heat-resistant and insulating material is fitted and held in the recess of the water-cooled jacket, and the seal is placed between the inner bottom of the recess and the back of the sealing material. It has a built-in spring that brings the inner circumferential surface of the material into close contact with the outer circumferential surface of the electrode, and the sealing material closes the gap between the inner circumferential surface of the electrode insertion hole and the outer circumferential surface of the electrode, and also follows the wear and tear of the electrode. displacing the sealing material to follow the electrode by the spring;
A sealing device around an electrode for a steelmaking furnace, characterized in that the closed state is maintained.
