Abstract
The utility model discloses an electric furnace cover which mainly comprises a cover body. A suspension ring and three electrode holes are arranged on the cover body. The electric furnace cover is characterized in that the thickness of the cover body is gradually reduced from the center to the periphery; and the cross section of the cover body is circular. Preferably, a semicircular groove is formed on the lateral wall of the cover body. More preferably, three semicircular grooves are formed at equal intervals on the lateral wall of the cover body. The upper end surface of the electric furnace cover inclines from the center to the periphery, so that dust can fall off under the action of gravity and is prevented from accumulating, thereby obtaining good heat radiation performance, improving the heat resistance of the electric furnace cover and prolonging the service life of the electric furnace cover.
Description
Technical field
The utility model relates to a kind of furnace equipment of making steel usefulness, especially a kind of bell of electric furnace.
Background technology
Electric furnace is as steel melting furnace commonly used, characteristics such as, efficient height good with its steel-making quality iron and steel domain use very extensive, along with development of science and technology, electric furnace becomes the steel melting furnace of main flow gradually.The bell of electric furnace is the critical elements of electric furnace, in smelting process, the working conditions of the bell of electric furnace is very abominable, it will bear the high temperature more than 1400 degrees centigrade usually, and high-temperature duration is longer, especially especially the bell of electric furnace has been proposed higher high temperature resistant requirement in the long high temperature refining of reduction period.And the resistance to elevated temperatures of the bell of electric furnace is except the material resistance toheat of itself, also relevant (especially being exposed at the upper surface in the outside) with its surperficial thermal diffusivity, the upper surface of the bell of existing electric furnace is generally planar design, after being infected with in the above, dust is not easy to be scattered, the long a large amount of situations about covering of dust that are easy to generate of time one, thereby influenced the thermal diffusivity of the bell of electric furnace, and then influenced its work-ing life.
Summary of the invention
The purpose of this utility model is the bell that a kind of upper surface of providing for the deficiency that solves above-mentioned technology can prevent dust accretions, electric furnace that thermal diffusivity is good.
In order to achieve the above object, the bell of the electric furnace that the utility model is designed, it mainly comprises lid, lid is provided with suspension ring and three electrode holes, it is characterized in that described lid thickness reduces gradually by around the middle mind-set, and the cross section of this lid is circular.Such structure makes the upper surface of bell be tilted by middle mind-set all around, thereby can make dust dropping under the effect of gravity, prevents to pile up.
As preferably, the sidewall of described lid is provided with semi-circular groove.The sidewall equal intervals that more preferred scheme is described lid is provided with three semi-circular groove.
In order to reach good sealing effectiveness, the sidewall of described lid can be inclined to set.
As preferably, described electrode hole is equilateral triangle and arranges.
In order to ensure the stressed equilibrium of suspension ring, preferred scheme is totally three on described suspension ring, is equilateral triangle and arranges, and can prevent that the lid that causes because of unbalance stress from damaging.
The bell of the electric furnace that the utility model obtains, the upper surface of bell is all around tilted by middle mind-set, thereby can make dust dropping under the effect of gravity, prevent to pile up, thereby can obtain good thermal diffusivity, improve the resistance toheat of the bell of electric furnace, thereby prolong its work-ing life.
Description of drawings
Fig. 1 is the structural representation of embodiment 1;
Fig. 2 is the sectional view that A-A ' locates among Fig. 1;
Fig. 3 is the structural representation of embodiment 2.
Among the figure: lid 1, suspension ring 2, electrode hole 3, semi-circular groove 4.
Embodiment
The utility model will be further described in conjunction with the accompanying drawings below by embodiment.
As shown in Figure 1, 2, the bell of the described electric furnace of present embodiment, it mainly comprises lid 1, and lid 1 is provided with suspension ring 2 and three electrode holes 3, and described lid 1 thickness reduces gradually by around the middle mind-set, and the cross section of this lid 1 is circular.The sidewall of described lid 1 is inclined to set.
The bell of the electric furnace that the utility model obtains, the upper surface of bell is all around tilted by middle mind-set, thereby can make dust dropping under the effect of gravity, prevent to pile up, thereby can obtain good thermal diffusivity, improve the resistance toheat of the bell of electric furnace, thereby prolong its work-ing life.
As shown in Figure 3, the bell of the described electric furnace of present embodiment, it mainly comprises lid 1, the sidewall equal intervals of described as different from Example 1 lid 1 is provided with three semi-circular groove 4.Described electrode hole 3 is equilateral triangle to be arranged, and totally three on described suspension ring 2 are equilateral triangle and arrange, and can prevent that the lid 1 that causes because of unbalance stress from damaging.
The bell of the electric furnace that the utility model obtains, the upper surface of bell is all around tilted by middle mind-set, thereby can make dust dropping under the effect of gravity, prevent to pile up, thereby can obtain good thermal diffusivity, improve the resistance toheat of the bell of electric furnace, can prevent that the lid 1 that causes because of unbalance stress from damaging simultaneously, thereby prolong its work-ing life.
