Abstract
The utility model relates to a furnace cover of a non-pressure water-cooled electric arc furnace. The furnace cover is formed by the combination of a round steel cover cap (1) and a steel cover edge (2). The steel cover edge (2) is provided with an interlayer water channel (6) which is arranged in a ring shape; a blind plate (7) and a water inlet (8) are arranged in the interlayer water channel (6); the steel cover cap (1) also adopts the hollow interlayer structure, and fan-shaped water channels (9) are arranged in the hollow interlayer in the radial direction and at equal intervals; a partition wall (11) is arranged between the fan-shaped water channels (9) of the steel cover cap (1) and the interlayer water channel (6) of the steel cover edge (2); and limber holes (12) are formed on the partition wall (11). The utility model has the advantages of long service life, low maintenance and corrosion elimination.
Description
Technical field
The utility model relates to the improvement of electric arc furnaces bell structure, particularly a kind of no setting-out cold plasma stove bell.
Background technology
At present, the brick layed electric arc furnaces bell that the smelting industry electric arc furnaces is used, because of it all is to build by laying with refractory brick to form, and will be at electrode hole, floss hole periphery lining water-cooled circle, because the effect of three electrodes, cause the central part temperature high especially, corrode seriously, in use the roof brick at this position at first falls sheet and peels off or fall the brick top of collapsing, directly affect the service life of bell, increase production cost.
The utility model content
Technical problem to be solved in the utility model is the above-mentioned defective at existing brick layed bell, particularly short service life in order to overcome the brick layed bell, easily falling sheet peels off, fall the brick top problem of collapsing, a kind of long service life is provided, maintenance is little, the no setting-out cold plasma stove bell of no erosion.
The following technical scheme of the utility model: a kind of no setting-out cold plasma stove bell, steel block and steel lid edge be combined into by circle have electrode hole, floss hole on the steel block; Steel block bottom surface weldering dross square groove or barb; Described steel Gai Yuan has the interlayer water channel of arranging ringwise, and a blind plate is arranged in the interlayer water channel, and water inlet is positioned at a side of blind plate; Described steel block also is the hollow interlayer structure, and its cross sectional shape is low the overarching of middle high periphery; The uniformly-spaced fan-shaped water channel of radial arrangement is arranged in this hollow interlayer, and these fan-shaped water channels get around above-mentioned electrode hole and floss hole in steel block hollow interlayer, and assemble the pass-out mouth of a river in the most central position; Establish partition wall between the interlayer water channel of the fan-shaped water channel of steel block and steel lid edge, the interlayer water channel begins to establish 2～3 limbers at the partition wall of corresponding each fan-shaped water channel successively from water inlet.
The utility model has the advantages that: the overall performance of this bell is good, and the steel block is withstand voltage at 10kg/cm
2More than, saving a large amount of refractory brick and fill out wadding, energy-conservation joint wadding utilizes recirculated water cooling steel block, high temperature resistant erosion, no flake-off sheet or fall the brick top phenomenon of collapsing has reduced maintenance workload, and be more than ten times of traditional brick layed bell service life.
Description of drawings
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail.
