Description
Technical field
The utility model belongs to steelmaker's fixture fields, more particularly to a kind of converter taphole and surrounding work to after erosion
Make the mould that layer is quickly repaired.
Background technology
Converter taphole is the unique passage of converter tapping.In tapping process, etch and souring in high-temperature molten steel
Under, cause tapping hole internal orifice expanding and damage, and working lining around converter taphole is formed irregular depression defect phenomenon,
Blowing out of having to is repaired.
At present, mammoth conveter is generally repaiied using repairing stove machine to the defect of above-mentioned tapping hole and the depression of converter working lining
It is multiple, repair stove machine and gunning refractory is sprayed at around converter taphole by spray repair pipe.Because tapping hole does not have mould and stop gauge,
Gunning refractory can flow out from tapping hole, therefore repair stove machine and can only spray a small amount of gunning refractory every time, after the drying of last gunning refractory again
Next time, spray repair repeatedly not only greatly extends repair time, makes each repairing will blowing out 40- up to mending for spraying
50min, have a strong impact on the operating rate and yield of converter；And needing 3-5 people to coordinate, operation at high temperature, labor intensity is very big.
Simultaneously because repair time extends, the fuel consumption of converter heating is added, increases production cost.
In the prior art, number of patent application：201220641896.8 disclose working lining around a kind of converter taphole to repair
Multiple device, limit tapping hole is blocked using top, top provides support force by spring, but effect is not to manage very much in actual use
Think, spring can lose elasticity because of use environment, and then the phenomenon that top departs from occurs.
The content of the invention
For overcome the deficiencies in the prior art, the purpose of this utility model is to provide working lining around a kind of converter taphole and repaiied
Multiple device, it is simple in construction, it is easy to operation, greatly shorten repair time, extend the service life of tapping hole；What can be stablized will repair
Device is integrally attached at tapping hole, it is ensured that obturator is not fallen off in whole mending course.
To achieve the above object, the utility model is achieved through the following technical solutions：
Working lining obturator around a kind of converter taphole, including mould pipe, hand lever, mould pipe afterbody are provided with hand lever, in addition to
Kelly, kelly are symmetrically fixed on mould pipe both sides, and kelly is S-shaped structure, is welded and fixed at the top of kelly with mould pipe, bottom is tip knot
Structure.
Described mould pipe afterbody carries the slope head of interior receipts.
Described kelly is made by round steel, and round steel external diameter is 15~20mm.
It is more than card with mould pipe outer wall spacing with mould pipe outer wall space D=18~30mm, kelly bottom in the middle part of described kelly
Bar middle part and mould pipe outer wall spacing.
Compared with prior art, the beneficial effects of the utility model are：
Overall structure is simple, can greatly shorten repair time, and repair time is only to use to repair the 1/10 of stove machine, is repaired every time
Furnace outage time 40min can be reduced, so as to the relative operating rate and steel output for improving converter；Tapping hole service life is extended,
Reduce steel tapping hole replacement number；Obturator can be fixed on using kelly by tapping hole, while the S-shaped structure of kelly itself has bullet
Property, and not changing elasticity with the temperature of tapping hole, kelly can be fused in molten steel during tapping, and operation is taken out without follow-up, you can real
Existing obturator comes off.The slope head of interior receipts is arranged on mould pipe afterbody, and obturator can enter tapping hole by mould pipe afterbody.

Fig. 3 is the connection diagram of kelly and mould pipe.
In figure：1- slopes head 2- mould pipe 3- kelly 4- connecting rod 5- prong structure 6- hand levers.
Embodiment
The utility model is described in detail with reference to Figure of description, it should be noted that of the present utility model
Implementation is not limited to following embodiment.
See Fig. 1-Fig. 3, working lining obturator around a kind of converter taphole, including mould pipe 2, hand lever 6, the afterbody of mould pipe 2 are set
There are hand lever 6, in addition to kelly 3, kelly 3 is symmetrically fixed on the both sides of mould pipe 2, and kelly 3 is S-shaped structure, the top of kelly 3 and mould pipe 2
It is welded and fixed, bottom is prong structure 5.
Wherein, the afterbody of mould pipe 2 carries the slope first 1 of interior receipts.Kelly 3 is made by round steel, and round steel external diameter is 15~20mm, preferably
16~18mm.The middle part of kelly 3 and outer wall space D=18 of mould pipe 2~30mm, preferably 20~25mm, the bottom of kelly 3 with outside mould pipe 2
Wall spacing is more than the middle part of kelly 3 and the outer wall spacing of mould pipe 2.
Embodiment：
See Fig. 1-Fig. 3, working lining obturator around converter taphole, including mould pipe 2, hand lever 6, kelly 3, the afterbody of mould pipe 2
Provided with hand lever 6, the both ends of connecting rod 4 are fixed on the inwall of mould pipe 2, and hand lever 6 is fixedly connected by connecting rod 4 with mould pipe 2, and kelly 3 is symmetrical
The both sides of mould pipe 2 are fixed on, kelly 3 is S-shaped structure, and the top of kelly 3 is welded and fixed with mould pipe 2, and bottom is prong structure 5.Mould pipe
2 afterbodys carry the slope first 1 of interior receipts, and kelly 3 is made by round steel, and round steel external diameter is 16mm, after repairing, can just it is fused to steel
In water.The middle part of kelly 3 and the outer wall space D of mould pipe 2=20mm, the bottom of kelly 3 and the outer wall spacing of mould pipe 2 be more than the middle part of kelly 3 with
The outer wall spacing of mould pipe 2.The external diameter of mould pipe 2 is smaller 5~30mm than converter taphole diameter.Mould pipe 2 is process using seamless steel pipe, mould
The length of pipe 2 is the 40%-55% of converter taphole length.
When tapping hole is repaired, first by 90 ° of converter tipping, make tapping hole axis axis perpendicular to horizontal plane, will using hand lever 6
In obturator insertion tapping hole, and obturator front end is set to lean out the appropriate height of tapping hole, obturator will be repaiied in the presence of kelly 3
Multiple device is fixed in tapping hole.Packed mending material can be manually launched to incomplete position around tapping hole by repairing personnel, gone out
The intraoral obturator of steel serves the effect of template, so that the mending material melted under high temperature is equably residual by tapping hole and surrounding
Position is lacked to repair completely.Because the prong structure 5 of kelly 3 acts on, obturator is set voluntarily not exit.Above-mentioned repair process is in 3-
In 5min, you can complete.
The utility model overall structure is simple, obturator can be fixed on into tapping hole using kelly 3, meanwhile, the S of kelly 3
Shape structure itself is flexible, and does not change elasticity with the temperature of tapping hole, and kelly 3 can be fused in molten steel during tapping, without after
It is continuous to take out operation, you can to realize coming off for obturator.The slope first 1 of interior receipts is arranged on the afterbody of mould pipe 2, and obturator can be by the tail of mould pipe 2
Portion enters tapping hole.
