Description
Technical field
The utility model is related to cupola well, especially a kind of erosion leading type arc furnace bottom cupola well.
Background technology
Blast furnace is the key equipment of ironmaking production, in order to improve production efficiency, improves the production iron of unit heat size, smelts iron work
Author does one's utmost to extend blast furnace furnace service life, by prolonging campaign as one of the important goal of pursuit.Whether judge generation stove labour
Termination Main Basiss are cupola well furnace bottoms, furnace bottom cupola well high temperature liquid iron it is long-term wash away erosion under, bricking is thinned, cupola well can occur
The major accidents such as burn-through, the termination for causing stove to be used as a servant.Existing furnace bottom hearth structure is all made of the form at open hearth bottom, i.e., from furnace bottom stove
Cylinder intersection to blast furnace center is a plane.When due to blast fumance, blast furnace center is located dynamic change for a long time
Dead coke heap, it is in very much, when molten iron is discharged circulation state, therefore, furnace bottom hearth erosion and molten iron flow to corrode slower than intersection more
The bottom of a pan is formed and is corroded, the life of the blast furnace is shorter.
Utility model content
The purpose of this utility model is to provide a kind of erosion leading type arc furnace bottom cupola wells, can reduce the bottom of a pan and invade
Erosion improves the life of the blast furnace.
Technical solution adopted by the utility model to solve its technical problems is：A kind of erosion leading type arc furnace bottom stove
The first liner is arranged in furnace body for cylinder, including furnace body, is arranged the second liner in the first liner, the second liner bottom setting opening to
On arc-shaped pot bottom.
The utility model in order to further solve its technical problem used by technical solution be：The arc-shaped pot bottom with
The table top of annular is set between the second liner side wall.The height at the arc-shaped pot bottom is L, L 300-700mm.Described
Two liner side walls are the up big and down small conical surface.Thinnest part thickness >=200mm of second liner.The section of the table top
Width is 1000mm.
The utility model has the beneficial effects that：The utility model can play optimization bottom hearth of blast furnace structure, and in height
Beneficial intervention is carried out to the flowing of erosion location and molten iron, clinker when stove produces, makes blast furnace erosion pattern by common garlic
Shape becomes pot bottom-shape, mutually coordinates with furnace bottom hearth structure, extends the life of the blast furnace.The utility model changes traditional open hearth completely
Bottom design concept focuses more on blast furnace realistic application conditions, physical interventions is carried out to the original factor for influencing the life of the blast furnace, to invading
Erosion pattern guides, and blast furnace is promoted to form efficient, long-lived state in use, moreover it is possible to save material, reduce and build
Project cost.Bottom hearth of blast furnace is using this structure and after going into operation, and molten iron is easier to collect at blast furnace center when non-slagging iron,
Discharge slag iron when blast furnace in slag iron circulation state can mitigate significantly, thus significantly reduce furnace bottom cupola well junction it is various because
The various erosion chances such as chemistry caused by slag iron flowing, thermal stress variation, increase the erosion chance at blast furnace center, keep blast furnace final
Erosion shape by garlic shape towards pot bottom-shape change, since bearth brick lining is very thick, compare resistant to corrosion.The utility model can be whole
The service life for extending furnace bottom cupola well extends blast furnace furnace service life to whole.Meanwhile the utility model has the advantages of simple structure and easy realization,
Thus the prolonging campaign brought understands the benefit in terms of indirect belt comes production efficiency, safety, economic dispatch.
Description of the drawings
Fig. 1 is the utility model structure diagram.
Specific implementation mode
The first liner 2 is arranged in furnace body 1 as shown in Figure 1, including furnace body 1 in a kind of erosion leading type arc furnace bottom cupola well,
Second liner 3 is set in first liner 2, and the arc-shaped pot bottom 4 of opening upwards is arranged in 3 bottom of the second liner.This structure can rise
To optimization bottom hearth of blast furnace structure, and beneficial do is carried out to the flowing of erosion location and molten iron, clinker in blast fumance
In advance, so that blast furnace erosion pattern is become pot bottom-shape from common garlic shape, mutually coordinate with furnace bottom hearth structure, extend the life of the blast furnace.
This structure changes traditional open hearth bottom design concept completely, focuses more on blast furnace realistic application conditions, to influencing the blast furnace longevity
The original factor of life carries out physical interventions, is guided to erosion pattern, promotes blast furnace to be formed in use efficient, long-lived
State, moreover it is possible to save material, reduce construction engineering cost.Bottom hearth of blast furnace is using this structure and after going into operation, non-slagging
Molten iron is easier to collect at blast furnace center when iron, and slag iron circulation state can mitigate significantly in blast furnace when discharging slag iron, thus greatly
The various erosion chances such as the big various chemistry caused by slag iron flows for alleviating furnace bottom cupola well junction, thermal stress variation, add
The erosion chance at big blast furnace center, the erosion shape for keeping blast furnace final is changed by garlic shape towards pot bottom-shape, due to bearth brick lining
It is very thick, compare resistant to corrosion.Therefore this structure can integrally extend the service life of furnace bottom cupola well, to which the whole State of Blast Furnace that extends uses as a servant the longevity
Life.Meanwhile it is this have the advantages of simple structure and easy realization, the prolonging campaign that thus brings can indirect belt come production efficiency, safety, economy
Etc. benefit.
The table top 5 of annular is set between 3 side wall of arc-shaped pot bottom 4 and the second liner.Table top 5 can be convenient for being laid with pillow
Wood, the Operational preparations operation such as do iron mouth.
The height at the arc-shaped pot bottom 4 is L, L 300-700mm.This structure can play certain resistance and corrode
Effect, promote cupola well that can keep good working order, delay the second liner of furnace bottom 3 start corrode time, to carry
The blast furnace bottom service life.
Second liner, 3 side wall is the up big and down small conical surface 6.When this structure is convenient for feeding stove is fallen under clinker
Bottom, when avoiding charging, clinker attaches on 3 side wall of the second liner.
Thinnest part thickness >=200mm of second liner 3.This structure can play certain support at blow-on initial stage
Erosion-resistant effect promotes cupola well that can keep good working order, and the second liner of furnace bottom 3 is delayed to start the time corroded,
To improve the life of bottom.
The cross-sectional width of the table top 5 is 1000mm.
Specific embodiment of the present utility model is described above in association with attached drawing, but these explanations cannot be understood to
The scope of the utility model is limited, the technology contents of the not detailed description of the utility model are known technology.
