[0002] At present, in metal smelting and processing, electric furnace is a kind of metal smelting equipment that is widely used, and its usage is huge. As an important part of electric furnace, electric furnace cover mainly plays the role of heating equipment installation and fixing, electric furnace insulation and Safety protection and other functions play an important role in the operation performance and operation safety of the electric furnace. However, in actual use, it is found that the electric furnace cover currently used has poor thermal insulation performance, and the heat loss during the operation of the electric furnace is large. High energy consumption but low heating efficiency

The invention discloses a novel high-temperature-resistant electric arc furnace (EAF) roof comprising a furnace roof body, wherein a cover plate is arranged at the bottom of the furnace roof body; a high-temperature-resistant reflective layer is arranged on the top of the cover plate; a refractory layer is arranged on the top of the high-temperature-resistant reflective layer; a high-fiber block layer is arranged on the top of the refractory layer; a cover cavity is arranged on the top of the high-fiber block layer; an outer case is arranged on the top of the high-fiber block layer; a handle is arranged on the top of the outer case; and the surface of the outer case is provided with through holes. Through the arrangement of the high-temperature-resistant reflective layer, the novel high-temperature-resistant EAF roof can reflect electric arc light heat energy in a furnace to the charge in the furnace, thereby reducing heat loss in the furnace. The refractory layer and the through holesare arranged to effectively prevent damage to the furnace roof due to excessive heat so as to improve product quality.
Description
technical field [0001] The invention relates to the field of electric furnace covers, in particular to a novel high temperature resistant electric furnace cover. Background technique [0002] At present, in metal smelting and processing, the electric furnace is a very common metal smelting equipment with a huge amount of use. As an important part of the electric furnace, the electric furnace cover mainly plays the role of heating equipment installation and fixing, electric furnace insulation and Safety protection and other functions play an important role in the operation performance and safety of the electric furnace. However, in actual use, it is found that the current electric furnace cover has poor thermal insulation performance, and the heat loss during the operation of the electric furnace is large. High energy consumption but low heating efficiency. [0003] Therefore, it is necessary to invent a kind of novel high temperature resistant electric furnace cover to solv...
