Abstract

The invention discloses a novel insulating base for an ore-smelting electric furnace. The novel insulating base comprises a furnace cover. The furnace cover and an electrode protective screen are connected in an inserting mode. A sealing ring pedestal is arranged at the top end of the furnace cover, and a supporting frame is arranged at the external diameter position of the sealing ring pedestal.A sealing ring II is arranged at the top end of the supporting frame, and the external diameter of the sealing ring II is fixedly connected with the supporting frame. A sealing brick ring is arrangedat the top end of the sealing ring II. An insulating box II is arranged at the external parameter position of the sealing brick ring, and the external diameter of the sealing brick ring is elasticallyconnected with the insulating box II. The insulating box II is fixedly connected with the supporting frame. A sealing ring I is arranged at the top end of the sealing brick ring, and the external diameter of the sealing ring I is fixedly connected with the insulating box II. An insulating box I which is fixedly connected with the insulating box II is arranged on the outer side of the insulating box II. The insulating box I is fixedly connected with a primary beam and a secondary beam. By adoption of the sealing brick ring, the electrode protective screen can effectively achieve insulated connection, and a good insulation effect is achieved. The sealing effect can be improved through the sealing rings, and the protective fixation function is also achieved. The primary beam and the secondary beam are connected with the insulating boxes, and the insulating effect is good.

Description

technical field [0001] The invention belongs to the technical field of insulation devices for submerged heat electric furnaces, and in particular relates to a novel insulating seat for submerged heat electric furnaces. Background technique [0002] In the prior art, the ore-heat electric furnace uses the three-phase electrodes to consume electric energy and generate heat to smelt the ore-heat material. During the smelting process, all the current is transmitted to the electrode insert material through piece-by-piece contact elements, also called copper tiles. Layers do work in a short-circuit manner, and the operator controls the current to achieve an appropriate furnace temperature to refine the mineral heat in the crucible. High current, high power, and high passability are the characteristics of submerged heat electric furnaces. Therefore, during the smelting process, submerged arc furnaces are prone to discharge and arc ablation everywhere due to insulation failure or...
