The utility model relates to the technical field of submerged arc furnace protection, in particular to a submerged arc furnace
slag outlet protection device which comprises a mounting plate. The protective cylinder is mounted on the mounting plate, the movable plate is mounted at the outer end of the mounting plate, a lifting groove is formed in the end, away from the protective cylinder, of the movable plate, a lifting block is slidably connected into the lifting groove, a protective plate is connected to the end, away from the lifting groove, of the lifting block, and a
handle is connected to the end, away from the lifting block, of the protective plate; a sliding rod is slidably connected into the protection plate, a
handle is connected to the end, away from the protection plate, of the sliding rod, a clamping ring is connected to the end, away from the
handle, of the protection plate, a limiting ring is connected into the clamping ring, and a movable groove is formed in the lower side in the protection plate. Through linkage of multiple components, efficient
slag removal and personnel protection are synchronously carried out, the risk caused by high-temperature approaching operation is avoided, high-temperature splashing can be dynamically blocked in the cleaning process, and the
operation safety and efficiency are remarkably improved.
