Abstract
The utility model discloses a kind of flue structure for large-capacity ore furnace, including three flues being distributed on mineral hot furnace circumferencial direction, described flue includes the dado extended up bottom mineral hot furnace, the oblique flue tube being arranged on described dado and extend obliquely, and it is arranged at the smoke guiding cover on described oblique flue tube top.Described in the utility model in the flue structure of large-capacity ore furnace, make flue gas transmission path substantially shorten by changing the set-up mode of flue, can make flue gas that ferrosilicon smelting process produces more directly, quickly derive；Extend up simultaneously as the external boundary of flue i.e. dado is the bottom from mineral hot furnace, therefore can be obviously reduced the volume of mineral hot furnace, be conducive to saving construction cost, and the execute-in-place for workman provides convenient.
Description
Technical field
This utility model relates to a kind of flue structure, particularly relates to a kind of flue structure for large-capacity ore furnace.
Background technology
Mineral hot furnace is also known as electric-arc furnace or resistance electric furnace.
It is mainly used in reducing and smelting Ore, the raw material such as carbonaceous reducing agent and solvent.Mainly produce ferrosilicon, ferromanganese, ferrochrome,
The ferroalloy such as ferrotungsten, silicomangan, is the industrial chemicals such as essential industry raw material and carbide in metallurgical industry.
Its work characteristics is to use carbonaceous or magnesia refractories to make furnace lining, uses from training electrode.Electrode inserts furnace charge and enters
Row arc-covering slag operation, utilizes the energy of electric arc and electric current to pass through furnace charge, produces energy because of the resistance of furnace charge and carry out smelting metal, successively
Charging, batch (-type) goes out scum, a kind of industrial furnace worked continuously.
Mineral hot furnace mainly by furnace shell, bell, furnace lining, short net, water-cooling system, smoke evacuation system, dust pelletizing system, Electrode Fluctuation and
Jacking system and various electric equipments etc. form.
In prior art, cylindrically, and its flue protrudes out cylinder edge and is separately provided mineral hot furnace, and this results in
The overall volume of mineral hot furnace becomes big, improves construction cost, and workman's execute-in-place there is also inconvenience.
Utility model content
This utility model is for the drawback of prior art, it is provided that a kind of flue structure for large-capacity ore furnace.
Flue structure for large-capacity ore furnace described in the utility model, including being distributed on mineral hot furnace circumferencial direction
Three flues, described flue includes the dado extended up bottom mineral hot furnace, is arranged on described dado and extends obliquely
Oblique flue tube, and be arranged at the smoke guiding cover on described oblique flue tube top.
Described in the utility model in the flue structure of large-capacity ore furnace, described dado is built into by masonry, and height is
Between 0.8 meter to 1.2 meters.
Described in the utility model in the flue structure of large-capacity ore furnace, described oblique flue tube includes outside metal
Shell, the inwall at described metal shell is attached with flame retardant coating.
Described in the utility model in the flue structure of large-capacity ore furnace, make cigarette by changing the set-up mode of flue
Gas transmission path is substantially shortened, and can make flue gas that ferrosilicon smelting process produces more directly, quickly derive；Simultaneously as cigarette
The external boundary in road i.e. dado is that the bottom from mineral hot furnace extends up, and therefore can be obviously reduced the volume of mineral hot furnace, favorably
In saving construction cost, and the execute-in-place for workman provides convenient.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the flue structure for large-capacity ore furnace described in the utility model.
Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is described in further detail, to make those skilled in the art with reference to explanation
Book word can be implemented according to this.
As it is shown in figure 1, the flue structure for large-capacity ore furnace described in the utility model, including being distributed in mineral hot furnace
Three flues on 1 circumferencial direction (Fig. 1 only represents a flue in three flues, below all enter as a example by this flue
Row explanation, two other flue structure is same).
Described flue specifically includes the dado 2 extended up from the bottom of mineral hot furnace 1, and be arranged on described dado 2,
And the oblique flue tube 3 extended obliquely, and it is arranged at the smoke guiding cover 4 on described oblique flue tube 3 top.This kind arranges flue
Mode makes flue gas transmission path substantially shorten, and can make flue gas that ferrosilicon smelting process produces more directly, quickly derive；With
Time, owing to the external boundary i.e. dado 2 of flue is to extend up from the bottom of mineral hot furnace 1, mineral hot furnace therefore can be obviously reduced
Volume, be conducive to saving construction cost, and the execute-in-place for workman provide convenient.
Described in the utility model in the flue structure of large-capacity ore furnace, described dado 2 is to be built by masonry 21
Becoming, its height, between 0.8 meter to 1.2 meter, the most both can ensure that and efficiently discharged flue gas, and can reduce again construction investment, with
Time, the most convenient with follow-up flue gas processing device is connected, and has extremely strong versatility.
In this utility model, described oblique flue tube 3 specifically includes metal shell 32, at the inwall of described metal shell 32
Being attached with flame retardant coating 31, described flame retardant coating 31 can be laid by refractory materials such as refractory brick and form.
Although embodiment of the present utility model is disclosed as above, but it is not restricted in description and embodiment
Listed utilization, it can be applied to various applicable field of the present utility model completely, for those skilled in the art,
It is easily achieved other amendment, therefore under the general concept limited without departing substantially from claim and equivalency range, this reality
It is not limited to specific details and shown here as the legend with description with novel.
Claims (3)
1. for a flue structure for large-capacity ore furnace, including three flues being distributed on mineral hot furnace circumferencial direction, its
Being characterised by, described flue includes the dado extended up bottom mineral hot furnace, is arranged on described dado and extends obliquely
Oblique flue tube, and be arranged at the smoke guiding cover on described oblique flue tube top.
2. the flue structure for large-capacity ore furnace as claimed in claim 1, it is characterised in that described dado is built by masonry
Becoming, height is between 0.8 meter to 1.2 meters.
