Abstract
The invention relates to a single cast house system of a double-taphole blast furnace. The single cast house system comprises the blast furnace, slag skimmers and a swinging chute, wherein two auxiliary cast houses are arranged on the blast surface, the two auxiliary cast houses are respectively arranged on the two sides of the blast furnace and distributed in a rectilinear manner, the auxiliary cast houses, the blast furnace and the original cast house are arranged in parallel, and the blast furnace is respectively provided with the tapholes along the directions of the two auxiliary cast houses; and the slag skimmers are arranged in the auxiliary cast houses, the slag skimmers are respectively connected to an iron trough and a slag trough, the tapholes are connected with the slag skimmers through the iron trough and then connected to the original cast house through the iron trough, the swinging chute is mounted at an outlet of the iron trough, and molten iron is further released into a molten iron tank through the swinging chute. According to the single cast house system disclosed by the invention, by increasing the auxiliary cast houses, the two tapholes can be arranged by forming an angle of 180 degrees, so that the positive effects of reducing or avoiding non-uniform erosion in the circumferential direction of a furnace hearth, stabilizing the production of the blast furnace, saving energy, reducing consumption, improving the operation quality of the blast furnace and prolonging the service life of the blast furnace can be realized.
Description
Technical field
The present invention relates to the ironmaking technology field, specifically a kind of pair of iron mouth blast furnace list casting house system.
Background technology
The blast furnace that is used to smelt iron needs to discharge molten iron through iron notch.Than large blast furnace two above iron notchs need be set generally, have the blast furnace of two iron notchs, two casting houses generally can be set according to routine, and with two iron mouths respectively correspondence be arranged in two casting houses, make two iron mouths be 180 ° of layouts each other.This decoration form is best, can guarantee that the blast furnace hearth circumferential direction corrodes evenly, helps the carrying out that produces.
Owing to receive the restriction of place, space and transport condition, tend to the blast furnace that has two iron notchs also is provided with a casting house, and simultaneously two iron notchs are and are less than or equal to 90 ° of angles and arrange.For large blast furnace, if the side that two iron mouths are arranged simultaneously promptly in casting house, it is inhomogeneous not only to cause the cupola well circumferential direction to corrode easily, and stable to blast furnace production, and energy-saving and cost-reducingly all constitutes influence.
Summary of the invention
To the deficiency of prior art, a kind of pair of iron mouth blast furnace list casting house system is provided, through increasing auxiliary casting house, realize that two iron mouths are the scheme that 180 ° of angles are arranged, to improve the operation of blast furnace quality, prolong blast furnace campaign.
The present invention solves the technical scheme that its technical problem takes: a kind of pair of iron mouth blast furnace list casting house system, comprise that blast furnace, skimmer and swing slip mouth, and said blast furnace is provided with two iron notchs; It is characterized in that; Also be provided with two auxiliary casting houses, two auxiliary casting houses are arranged in the blast furnace both sides, linearly distribute; Said auxiliary casting house and blast furnace together are arranged in juxtaposition with former casting house, are respectively equipped with an iron notch at said blast furnace along two auxiliary casting house directions; And in assisting casting house, be provided with skimmer, and said skimmer is connected respectively to iron runner and slag runner, and said iron notch is connected to former casting house through behind the skimmer through iron runner, and in the iron runner outlet swing slide mouth is installed.
The invention has the beneficial effects as follows: through increasing auxiliary casting house; Realize that two iron mouths are 180 ° of angles and arrange; It is inhomogeneous to alleviate or avoid the cupola well circumferential direction to corrode;, raising operation of blast furnace quality stable, energy-saving and cost-reducing to blast furnace production, and prolongation all can be played active effect blast furnace campaign.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Among the figure: 1 blast furnace, 2 iron notchs, 2 ' iron notch, 3 skimmers, 3 ' skimmer, 4 swing slide mouths, 4 ' swing slide mouth, 5 slag runners, 5 ' slag runner, 6 iron runners, 6 ' iron runner, 8 former casting houses, 7 auxiliary casting houses, 7 ' auxiliary casting house, 9 slag runners.
Embodiment
It is as shown in Figure 1,
A kind of pair of iron mouth blast furnace list casting house system comprises blast furnace, skimmer and swing slide mouth, and blast furnace is provided with two iron notchs, and two iron notch one the first from left right sides are symmetrical set about blast furnace.
Also be provided with two auxiliary casting houses, two auxiliary casting houses are arranged in the blast furnace both sides, and auxiliary casting house and blast furnace together are arranged in juxtaposition with former casting house, and auxiliary casting house and blast furnace linearly distribute.Be respectively equipped with an iron notch at blast furnace along two auxiliary casting house directions, iron notch passes through the outside transferring iron melt of iron runner, and in iron runner, is provided with skimmer, is used for scum and separates.The position of skimmer is arranged in corresponding auxiliary casting house.
Skimmer is connected respectively to iron runner and slag runner, and this is the design of routine, and iron notch is connected to former casting house through iron runner again after connecting skimmer through iron runner, and exports installation swing slide mouth at iron runner, and through swing slide mouth molten iron is discharged in the iron ladle.
Specifically; It slips mouth 4, swing by blast furnace 1, iron notch 2, iron notch 2 ', skimmer 3, skimmer 3 ', swing and slips compositions such as mouth 4 ', slag runner 5, slag runner 5 ', iron runner 6, iron runner 6 ', former casting house 8, auxiliary casting house 7, auxiliary casting house 7 ', and former shared slag runner 9.The auxiliary casting house that increases newly 7 and auxiliary casting house 7 ' be arranged symmetrically in the both sides of blast furnace 1 respectively, and together arranged side by side in blast furnace 1 with former casting house 8.Iron notch 2, iron notch 2 ' are arranged in auxiliary casting house 7 and auxiliary casting house 7 ' direction; Skimmer 3, skimmer 3 ' are arranged in auxiliary casting house 7 and the auxiliary casting house 7 '; Swing slide mouth 4, swing slide mouth 4 ' still are retained in the former casting house 8; One end of slag runner 5, slag runner 5 ' is connected with skimmer 3, skimmer 3 ' respectively, and the other end is connected with former shared slag runner 9; Iron runner 6, iron runner 6 ' one end are connected with skimmer 3, skimmer 3 ' respectively, and the other end is connected with swing slide mouth 4, swing slide mouth 4 ' respectively.
The invention property two iron notchs are 180 ° of layouts and single casting house problem solves; No matter be overhauling reform blast furnace or newly-built blast furnace; Be 180 ° of layouts as long as relate to two iron notchs, and have only a casting house to belong to this patent protection domain.
Except that the described technical characterictic of specification sheets, be the known technology of those skilled in the art.
