Abstract

The invention provides a submerged arc furnace electrode sealing device which is arranged between a water-cooling protection screen of an electrode mast of a submerged arc furnace and a water-cooling jacket of a furnace cover. The submerged arc furnace electrode sealing device comprises a sealing ring and a sealing ring support; the sealing ring support is arranged on the water-cooling jacket of the furnace cover, and is fixedly connected with the water-cooling jacket through a fastener; the sealing ring is arranged in the sealing ring support, and makes close contact with the water-cooling protection screen; the sealing ring is made of fire-resistant materials. Because the sealing ring is made of the fire-resistant materials instead of cast copper, the submerged arc furnace electrode sealing device saves materials and cost, plays a role in sealing a gap between the electrode mast and the furnace cover, and ensuring that the electrode mast and the furnace cover are insulated, avoids the phenomenon that the furnace generates heat because an insulating plate in a traditional submerged arc furnace electrode sealing device burns, is carbonized and loses efficacy, and prolongs the service life of equipment like the furnace cover.

Description

technical field [0001] The invention relates to the field of metallurgical industry, in particular to an electrode sealing device for a submerged arc furnace. Background technique [0002] The submerged arc furnace is a submerged arc furnace, which is mainly used for the production of ferroalloy, calcium carbide, etc. At present, the gap between the electrode column and the furnace cover of the submerged arc furnace is mostly sealed by a cast copper sealing ring and a sealing ring support, such as figure 1 As shown, the traditional submerged arc furnace electrode sealing device includes a cast copper seal ring 5', a cast copper seal ring support 6' and an insulating plate 7', and the gap between the seal ring support 6' and the water cooling jacket 4' of the furnace cover 3' Connected by fasteners, there is an insulating plate 7' between the sealing ring support 6' and the water cooling jacket 4'. The insulating plate 7' is generally a silicone mica insulating plate, which ...
