Glass observation window for electrode self-consuming furnace

The utility model discloses a glass observation window for a consumable electrode furnace, and belongs to the field of metal smelting. The glass observation window comprises a window frame, white glass, high-strength glass and shading glass, the high-strength glass is high-temperature-resistant tempered glass. The window frame is provided with three clamping grooves, and the white glass, the high-strength glass and the shading glass are sequentially fixed to the clamping grooves from inside to outside through screws. The clamping groove on the outermost side is a movable clamping groove, a rotating shaft is arranged on one side of the movable clamping groove, the movable clamping groove can freely rotate around the rotating shaft, and the shading glass is arranged on the movable clamping groove; and a vacuum state is formed between the white glass and the high-strength glass. Strong light generated by the electric arc can be shielded, so that a worker can still check the condition in the furnace under the str
