Abstract
The utility model discloses an energy -conserving long service life's blast furnace crucibe, including the hearth, the hearth is located the inner chamber of furnace body, the hearth is constituteed with the hearth wall at the bottom of by the hearth, and the inner chamber of hearth wall leaves first thermal -insulated chamber, form along cross crisscross piling up by being no less than two -layer brick fuel with the hearth wall at the bottom of the hearth, and fill in the gap between the brick fuel and have fireproof cement, the inner chamber of brick fuel leaves the thermal -insulated chamber of second, the upper surface of brick fuel is opened there is the spacing groove, the lower terminal surface of brick fuel is provided with the stopper corresponding with the spacing groove, and this energy -conserving long service life's blast furnace crucibe can prevent at the in -process of sintering that the molten iron from getting into the inner structure of hearth corrosion at a seam hearth, has better heat preservation ability in addition, and is more effectual than present blast furnace crucibe energy -conservation, long service life.
Description
Technical field
This utility model relates to steel-making blast furnace technical field, is specially the blast furnace crucibe of a kind of energy-conservation long service life.
Background technology
The widely used brick fuel of current blast furnace crucibe and ceramic cup inner lining structure, wherein ceramic cup is built by laying bricks or stones formed by fritter corundum brick or bulk corundum prefabricated section.One of existing ceramic cup has the drawback that greatly very much: gap and the brickwork joint of ceramic cup masonry itself between ceramic cup masonry and brick fuel become weak link, slag molten iron is invaded by these gaps and destroys furnace lining and then reduce the service life of ceramic cup, cause that this blast furnace crucibe reduces actual life, and energy consumption is higher.
Summary of the invention
The purpose of this utility model is in that to provide the blast furnace crucibe of a kind of energy-conservation long service life, with the problem solving to propose in above-mentioned background technology.
For achieving the above object, this utility model provides following technical scheme: the blast furnace crucibe of a kind of energy-conservation long service life, including cupola well, described cupola well is positioned at the inner chamber of body of heater, described cupola well is formed with cupola well wall by the bottom of cupola well, the inner chamber of cupola well wall leaves the first heat-insulation chamber, form along cross staggered piling up by no less than two-layer brick fuel with cupola well wall at the bottom of described cupola well, and the gap between brick fuel is filled with fire prevention clay, the inner chamber of described brick fuel leaves the second heat-insulation chamber, the upper surface of described brick fuel has stopper slot, the lower surface of described brick fuel is integrally formed with the limited block corresponding with stopper slot.
Preferably, described cupola well scribbles fire prevention clay with the contact surface of body of heater.
Preferably, the upper surface of described brick fuel is provided with no less than a limited block.
Preferably, described limited block is hemispherical.
Compared with prior art, the beneficial effects of the utility model are: the blast furnace crucibe of this energy-conservation long service life, at cupola well, heat insulating and sealing cavity is set, greatly reduce the heat loss rate of blast furnace, improve the insulating power of blast furnace, leave cavity at the inner chamber of brick fuel simultaneously, the insulating power that improve blast furnace through a step, brick fuel was piled up with cross interlocking, reduce the seam quantity in brick fuel masonry volume, and at the surface configuration limited block of brick fuel, it is prevented from brick fuel and lateral displacement occurs in the process of piling up, make the seam between brick fuel less, in the process of sintering, it is prevented from molten iron and enters the internal structure of corrosion at a seam cupola well, improve the service life of cupola well, the blast furnace crucibe of this energy-conservation long service life contrasts existing blast furnace crucibe good energy-conserving effect, long service life.
Accompanying drawing explanation
Fig. 1 is this utility model structural representation；
Fig. 2 is A portion of the present utility model schematic enlarged-scale view；
Fig. 3 is brick fuel structural representation of the present utility model.
In figure: at the bottom of 1 body of heater, 2 cupola wells, 3 cupola wells, 4 cupola well walls, 5 first heat-insulation chambers, 6 brick fuels, 7 second heat-insulation chambers, 8 stopper slots, 9 limited blocks, 10 fire prevention clay.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is clearly and completely described, it is clear that described embodiment is only a part of embodiment of this utility model, rather than whole embodiments.Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art obtain under not making creative work premise, broadly fall into the scope of this utility model protection.
nullRefer to Fig. 1-3，This utility model provides a kind of technical scheme: the blast furnace crucibe of a kind of energy-conservation long service life，Including cupola well 2，Cupola well 2 is positioned at the inner chamber of body of heater 1，Cupola well 2 is made up of at the bottom of cupola well 3 and cupola well wall 4，The contact surface of cupola well 2 and body of heater 1 scribbles fire prevention clay 10，Cupola well 2 and body of heater 1 can be bonded together，And there is good effect of heat insulation，The inner chamber of cupola well wall 4 leaves the first heat-insulation chamber 5，Greatly reduce the heat loss rate of cupola well 2，Improve the insulating power of cupola well 2，Reduce energy consumption，At the bottom of cupola well 3 and cupola well wall 4 form along cross staggered piling up by no less than two-layer brick fuel 6，And the gap between brick fuel 6 is filled with fire prevention clay 10，The inner chamber of brick fuel 6 leaves the second heat-insulation chamber 7，The upper surface of brick fuel 6 has stopper slot 8，The lower surface of brick fuel 6 is integrally formed with the limited block 9 corresponding with stopper slot 8，The upper surface of brick fuel 6 is provided with no less than a limited block 9，Arrange no less than a limited block 9，Limited block 9 is hemispherical，It is prevented from brick fuel 6 and lateral displacement occurs in the process of piling up，Make on cupola well 2 seam less，In the process of sintering，It is prevented from molten iron and enters the internal structure of corrosion at a seam cupola well 2，Improve the service life of cupola well 2.
While there has been shown and described that embodiment of the present utility model, for the ordinary skill in the art, being appreciated that when without departing from principle of the present utility model and spirit and these embodiments can be carried out multiple change, amendment, replacement and modification, scope of the present utility model is defined by the appended claims and the equivalents thereof.
