Abstract
The utility model discloses an incomplete iron of blast furnace tap drain discharges structure, including incomplete iron runner, remove incomplete iron swift current mouth, it includes and the upper portion and the columniform lower part of cylinder type be conical transition portion between upper portion and lower part to remove incomplete iron swift current mouth, the upper portion inlet porting, the ditch open height that highly is less than incomplete iron runner of entry, the height that highly is higher than the cast house platform of upper portion lateral wall that the entry corresponds, the ditch head and the entry position of incomplete iron runner correspond, upper portion still sets up the lifting hook, the lifting hook is fixed with the overhead traveling crane, the lower part corresponds with the entry of torpedo jar. The utility model has the advantages that: the utility model discloses a damage to cast house, railway and torpedo jar in realizing that molten iron in the incomplete iron runner is whole and flowing in the torpedo jar, has been avoided to the incomplete iron swift current mouth of preparation movable.
Description
Technical field
This utility model is related to steelmaking technical field, specifically a kind of residual ferrum discharge structure.
Background technology
Large blast furnace adopts iron storage type tap drain, when iron storage type tap drain iron reaches certain iron, needs to put net master
Residual ferrum is placed under repair to tap drain, safeguarded in ditch, generally can all be designed and be poured fixed residual iron runner, molten iron is smoothly flowed into
Enter in fish torpedo ladle in fish torpedo ladle or through swing spout.
During blast furnace residual iron placing, because cast house place limits, residual iron runner angle and length are fixed, residual iron placing
When, molten iron can not be fully entered in fish torpedo ladle, the damage that the molten iron of residual is caused to cast house, railway and fish torpedo ladle.
The content of the invention
The purpose of this utility model be to provide it is a kind of solve during residual iron placing molten iron overflow to cast house, railway and
Fish torpedo ladle causes the structure of damage problem, and concrete technical scheme is as follows：
A kind of residual ferrum discharge structure of blast furnace main channel, including residual iron runner, the residual ferrum of movement slips mouth；The residual ferrum of the movement slips mouth to be included
The top of column type and the bottom of cylinder, are the transition part of cone between top and bottom；The top inlet porting, it is described
Ditch open height of the height of entrance less than residual iron runner；Height of the height of the corresponding upper portion side wall of entrance higher than cast house platform；
The ditch head of the residual iron runner is corresponding with entry position；The top also sets up suspension hook, and the suspension hook is fixed with overhead traveling crane；The bottom
It is corresponding with the entrance of fish torpedo ladle.
Residual ferrum to be slipped and arrange refractory masses between the two-layered steel plates of the barrel of top, bottom and the transition part of mouth.
It is 300mm--500mm with a distance from fish torpedo ladle entrance that residual ferrum slips the lower end of mouth.
The utility model has the advantages that：The present invention slips mouth by making the residual ferrum of packaged type, realizes the molten iron in residual iron runner
All flow in fish torpedo ladles, it is to avoid the damage to cast house, railway and fish torpedo ladle.
Description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 is that residual iron runner slips mouth position schematic diagram with the residual ferrum of movement；
Fig. 3 slips mouth structure schematic diagram for residual ferrum.
Specific embodiment
This utility model is illustrated below in conjunction with the accompanying drawings, and as shown in Figure 1-Figure 3, this utility model includes residual iron runner 4, moves
Move residual ferrum and slip mouth 5；The residual ferrum of the movement slips mouth 5 including the top 10 of column type and the bottom 30 of cylinder, top 10 and bottom
It is the transition part 20 of cone between 30；The inlet porting 7 of the top 10, the height of the entrance 7 is less than the exit or entrance of a clitch 41 of residual iron runner
Height；Height of the height of the corresponding upper portion side wall 8 of entrance 7 higher than cast house platform 42；The ditch head of the residual iron runner with enter
7 positions of mouth correspondence；The top 10 also sets up suspension hook 9, and the suspension hook 9 is fixed by steel wire rope 2 with overhead traveling crane 1；The bottom 30
It is corresponding with the entrance of fish torpedo ladle 6.
Residual ferrum to be slipped and arrange refractory masses between the two-layered steel plates of the barrel on the top 10, bottom 30 and transition part 20 of mouth.
It is 300mm--500mm with a distance from fish torpedo ladle entrance that residual ferrum slips the lower end of mouth, and the distance can ensure to enter in residual flowing molten iron
During fish torpedo ladle, there is " crowded " in the gas that will not from inside to outside extrude with fish torpedo ladle, it is to avoid molten iron it is excessive.
Claims (2)
1. the residual ferrum discharge structure of a kind of blast furnace main channel, it is characterised in that：Including residual iron runner, the residual ferrum of movement slips mouth；The movement is residual
Ferrum slips mouth including the top of column type and the bottom of cylinder, is the transition part of cone between top and bottom；The top sets
Posting port, the height of the entrance is less than the ditch open height of residual iron runner；The height of the corresponding upper portion side wall of entrance is higher than cast house
The height of platform；The ditch head of the residual iron runner is corresponding with entry position；The top also sets up suspension hook, and the suspension hook is consolidated with overhead traveling crane
It is fixed；The bottom is corresponding with the entrance of fish torpedo ladle.
2. the residual ferrum discharge structure of blast furnace main channel according to claim 1, it is characterised in that：Residual ferrum slips the top of mouth, bottom
And refractory masses are set between the two-layered steel plates of the barrel of transition part.
