Description
Technical field
The EAF Technology field that the utility model is related to, specifically a kind of arc furnace cover structure.
Background technology
Electric arc furnaces is the electric furnace of the high melt ore and metal produced using electrode arc.During gas discharge formation electric arc
Energy is concentrated very much, and its arc area temperature is more than 3000 DEG C.For smelting metal, electric arc furnaces is than other converter technological flexibilities
Greatly, the impurity such as desulfuration, phosphorus can be effectively removed, furnace temperature is easily controlled, and occupation area of equipment is small, the melting suitable for superior alloy steel.
Electric arc furnaces is due to that can reach very high temperature in a short time, therefore its radiating is difficult the problem of turn into important.Electric arc furnaces is typically wrapped
Include shaft, bell and electrode.Wherein the design of bell also has a variety of, and one kind is that full refractory brick is piled up and formed, this kind of bell temperature
Control effect is bad, and cooling effect is not good, while also easily collapsing；Another is full heat radiating metal bell, this kind of bell
Not only cost is high, and because its hot channel spreads all over whole bell, its cooling is too fast, and temperature control difficulty is high.
With the raising of the development and metallurgy industry requirement of technology, arc furnace top cover is used since 1970s
Water cooled cover, due to using prefabricated component existing arc furnace ventral triangle area, and uses steel fibre fire proofed wood more more top prefabricated piece
Material cast is formed.Although electric arc furnaces full water cooling bell has service life length, saves the series of advantages such as refractory material, it is allowed to obtain
Obtained relatively broad application.But in arc furnace smelting procedure, furnace roof trigonum hot soak condition, and often by
To the souring of the influence and chemical erosion, the radiation of electrode arc light and flue dust of temperature shock, arc furnace is made
Position most weak in top cover whole system, and then it is shorter compared with the service life in other regions to be allowed to service life.Thus
People are cooled using various methods to furnace roof trigonum, so that the service life of furnace roof trigonum is extended.But
Because the refractory material of furnace roof trigonum bottom suffers erosion more seriously, easily aging is damaged, and occurs shelling of refractory, very
To caving in, thus the service life of furnace roof trigonum can be greatly affected because of the peeling of refractory material, and can be to electricity
Arc stove steel-making quality produces influence, and influences whether production efficiency.
Utility model content
The technical problems to be solved in the utility model is that there is provided a kind of arc furnace for problem present in background technology
Lid structure.
In order to solve the above technical problems, the technical scheme that is used of the utility model for：A kind of arc furnace cover structure, bag
Inner ring sleeve, lower ring oven lid, upper ring oven lid and top cover are included, the lower ring oven lid and upper ring oven lid are set to hollow sandwich structure,
The inner ring sleeve encloses the lower section for being located at lower ring oven lid, and the upper ring oven lid links together with lower ring oven lid, the top cover with it is upper
Ring oven lid is linked together, and the hanger for lifting by crane is provided with above the top cover, is covered in lower the ring oven lid and upper ring oven
Several water inlets communicated with the lower ring oven lid and upper ring oven lid inner hollow sandwich are radially uniformly laid with respectively
Pipe and outlet pipe.
Further, the arc furnace cover structure, many are additionally provided with a ring radially wherein being covered in the lower ring oven
Equally distributed reinforcement.
Further, the arc furnace cover structure, wherein the lower ring oven lid and upper ring oven lid and the same central shaft of top cover
Inclination is connected as one, wherein the radius ratio 5 of the lower ring oven lid, upper ring oven lid and top cover:3:1.
Using a kind of arc furnace cover structure described in the utility model, because lower ring oven lid and upper ring oven lid are set to
Hollow sandwich structure, by setting the water inlet pipe and outlet pipe that are communicated with hollow sandwich, is realized to stove using water-cooling structure mode
The cooling of lid, its good cooling results improve the heat dispersion of electric arc furnaces, so just can effectively prevent bell because being become by heat
Shape, improves the service life of equipment, also improves production efficiency.With simple in construction, the features such as easy to use.
