Abstract
The utility model discloses a furnace structure of an iron-making blast furnace, which is better in integrity. A ceramic cup hearth and a furnace bottom adopt a combination brick lining structure, the furnace bottom comprises a big charcoal brick furnace bottom brickwork and a ceramic cup furnace bottom brickwork, and the hearth is composed of a furnace shell, a cooling stave, a small charcoal brick and a ceramic cup hearth brickwork sequentially from outside to inside. The ceramic cup at the position where the furnace bottom is connected with the hearth adopts a ceramic cup combination brick brickwork, the ceramic cup brickwork is formed by combination bricks in masonry mode, the surface of the ceramic cup combination brick brickwork is an arc-shaped smooth surface, the radial extending width B of the arc-shaped smooth surface from the hearth to the furnace bottom is in a range from 1m to 1.5m, and the axial extending height H of the arc-shaped smooth surface from the hearth upward is in a range from 2.5m to 4m. The ceramic cup brickwork at the position where the furnace bottom is connected with the hearth is formed by the combination bricks in masonry mode, thereby being capable of reducing 'floating' of furnace bottom bricks, strengthening the integrity of the hearth and the furnace bottom, reducing washing strength of flowing iron water on the hearth and the furnace bottom and prolonging service life of the hearth and the furnace bottom. The furnace structure is mainly used in the iron-making blast furnace.
Description
Technical field
The utility model relates to a kind of furnace binding of blast furnace.
Background technology
At present, the furnace binding of iron-smelting blast furnace comprises furnace bottom and cupola well, and its furnace bottom and cupola well all are that straight line joins.There is following problem in such furnace binding:
The first, the furnace bottom molten iron is prone to make bottom brick " floating " after immersing brickwork joint.
The second, because cupola well and furnace bottom are that straight line joins, unsmooth, " the dead stockpile " that blast furnace forms in iron manufacturing process will make when molten iron is mobile to the increasing of washing away of furnace bottom, the anti-material of cupola well.
Three, furnace bottom-cupola well joint globality is relatively poor, and anti-material is prone to peel off under the elevated temperature heat load.
Cupola well, furnace bottom behind the erosion attack is rendered as " the bottom of a pan " shape more.
The utility model content
In order to overcome existing furnace bottom-relatively poor deficiency of cupola well joint globality, the utility model technical problem to be solved provides the better iron making blast furnace body structure of a kind of globality.
The utility model solves the technical scheme that its technical problem adopted: the iron making blast furnace body structure; Adopt heat pressure charcoal brick-ceramic cup cupola well, furnace bottom modular tile inner lining structure; Furnace bottom comprises big brick fuel masonry of well and ceramic cup masonry of well; The cupola well ecto-entad is furnace shell, cooling stave, little brick fuel cupola well masonry and ceramic cup cupola well masonry successively; The ceramic cup masonry of furnace bottom and cupola well joint adopts composite brick masonry, and masonry is to build by laying bricks or stones with modular tile to form, and the surface of said ceramic cup composite brick masonry is the arc even surface.
This arc even surface is by the radially extension width B=1～1.5m of cupola well to furnace bottom, and this arc even surface extends axially height H=2.5～4m by what furnace bottom made progress.
The beneficial effect of the utility model is: with at the bottom of the modular tile masonry heater and cupola well joint; Increased snap-in force to the ceramic cup masonry of well; Can alleviate " floating " of bottom brick, strengthen the globality of cupola well and furnace bottom, alleviate the scouring intensity of mobile molten iron cupola well, furnace bottom; Prolong the work-ing life of furnace bottom and cupola well, be mainly used in iron-smelting blast furnace.
Description of drawings
Fig. 1 is the synoptic diagram of the utility model furnace binding.
Fig. 2 is the vertical view of Fig. 1.
Be labeled as among the figure, the 1-furnace shell, the 2-cooling stave, the little brick fuel cupola well of 3-masonry, 4-ceramic cup composite brick masonry, 5-ceramic cup masonry of well, the big brick fuel masonry of well of 6-, B-is extension width radially, and H-extends axially height.
Embodiment
Below in conjunction with accompanying drawing the utility model is further specified.
Like Fig. 1, shown in Figure 2, the iron making blast furnace body structure of the utility model adopts ceramic cup cupola well, furnace bottom modular tile inner lining structure, and furnace bottom comprises big brick fuel masonry of well 6 and ceramic cup masonry of well 5; The cupola well ecto-entad is furnace shell 1, cooling stave 2, little brick fuel cupola well masonry 3 and ceramic cup cupola well masonry successively, and the ceramic cup of furnace bottom and cupola well joint adopts ceramic cup composite brick masonry 4, and ceramic cup composite brick masonry 4 is to build by laying bricks or stones with modular tile to form; Increased snap-in force, can alleviate " floating " of bottom brick, strengthened the globality of cupola well and furnace bottom ceramic cup masonry of well 5; The camber even surface is done on the surface of said ceramic cup composite brick masonry 4; Cupola well and furnace bottom joint present pan bottom shape, avoid cupola well and furnace bottom vertical connection, and it is smooth and easy that molten iron is flowed; Can improve generation furnace life, prolong furnace bottom, cupola well work-ing life.
As shown in Figure 1; According to different furnace bottom diameters, this arc even surface is by the radially extension width B=1～1.5m of cupola well to furnace bottom, and this arc even surface extends axially height H=2.5～4m by what furnace bottom made progress; The furnace bottom diameter is big more; Radially extension width B is beneficial to the smooth and easy of molten iron and flows with to extend axially height H big more accordingly, reduces its washing away furnace bottom, the anti-material of cupola well.
