The utility model discloses an explosion venting cover device of a submerged arc furnace and belongs to safe overpressure explosion venting devices. The explosion venting cover device is composed of an explosion venting cover, a short loop chain and the like. The explosion venting cover is embedded in a sealing groove around an explosion venting hole and sealed through refractory mortar in a filled mode. When the gas pressure in the furnace excesses a certain value, the explosion venting cover is ejected out of the sealing groove, the explosion venting hole is opened, the pressure in the furnace is relieved, and the problem that when the pressure in the furnace excesses the certain value, the pressure cannot be relieved and causes explosion is solved.
