Description
Technical field
The present invention relates to the parts of electric arc furnace, particularly to a kind of arc furnace cover.
Background technology
Electric arc furnace is the high melt Ore and the electric furnace of metal utilizing electrode arc to produce.Energy when gas discharge forms electric arc
Amount is concentrated very much, and arc district temperature is more than 3000 DEG C.For smelting metal, electric arc furnace is bigger than other converter technological flexibilities,
Can effectively remove the impurity such as sulfur, phosphorus, furnace temperature is easily controlled, and occupation area of equipment is little, is suitable to the melting of superior alloy steel.
Electric arc furnace generally comprises shaft, bell and electrode.Wherein the design of bell also has multiple, and one is full refractory brick heap
Block forms, and this kind of bell temperature control effect is bad, and cooling effect is the best, the most easily occurs collapsing simultaneously；Another kind is
Full heat radiating metal bell, this kind of bell not only cost is high, and owing to its hot channel spreads all over whole bell, its cooling
Too fast, it is high that temperature controls difficulty.
Summary of the invention
It is an object of the invention to provide a kind of structural strength good, save material, the arc furnace cover that temperature control effect is good.
The technical scheme realizing the object of the invention is: the present invention has body；It is characterized in that: described body includes supporting
Frame and fire-resistant lid；Support frame as described above includes foundation ring, top cover and tie-beam；The outside being located at top cover, the end, enclosed in described foundation ring
Circle is linked together by tie-beam with top cover；Described fire-resistant lid is fixedly installed between foundation ring and top cover and fills the full end
Gap between circle and top cover；Described top cover is provided with the electrode hole that power pole passes.
The inner hollow of above-mentioned top cover；It is fixed with on described body and is all connected, with the inside of top cover, the water inlet pipe communicated and goes out
Water pipe.
The upper surface of above-mentioned top cover is higher than the upper surface of foundation ring.
Above-mentioned top cover is circular cone shape；The small end face of described top cover is towards foundation ring；Described top cover is coaxial with foundation ring.
Above-mentioned foundation ring includes linking into an integrated entity and orthogonal enclosure and back-up ring；Described back-up ring is flat with the small end face of top cover
OK.
It is provided with reinforcement between above-mentioned enclosure and back-up ring.
Above-mentioned fire-resistant lid is piled up by polylith refractory brick and is formed.
Above-mentioned bracing frame includes three tie-beams in 120 degree of circle distribution；Described each tie-beam all big with top cover
The upper surface of end face and enclosure is fixing to be connected.
The present invention has positive effect: (1) present invention utilizes bracing frame to be supported by fire-resistant lid, its Stability Analysis of Structures,
It is not easy to occur collapsing；(2) present invention only arranges water inlet pipe and outlet pipe on top cover, while cooling range reduces,
Also ensure that the control effect of temperature is more preferable；(3) top cover of the present invention is higher than foundation ring, can be greatly enhanced bell arch knot
The stability of structure；(4) present invention utilizes refractory brick to pile up on bracing frame, can be greatly saved the usage amount of refractory brick,
Reduce manufacturing cost；(5) bracing frame of the present invention only need to utilize three tie-beams just can realize the highest support strength, system
Make simple.
Accompanying drawing explanation
It is clearly understood to make present disclosure be easier to, below according to specific embodiment and combine accompanying drawing, to this
Invention is described in further detail, wherein
