Abstract
The utility model relates to an auxiliary repairing device for the inner hole of the steel tapping hole of a revolving furnace. The auxiliary repairing device comprises a sleeve, a flared hopper, a strut and a lacing wire, wherein the flared hopper is welded at one end of the sleeve, the cross-shaped strut is arranged at the connection position of the sleeve and the flared hopper, and the lacing wire is connected at the cross point of the strut. After the auxiliary repairing device is inserted from the outer hole of the steel tapping hole and fixed, mending material can be filled to repair the furnace and finish the maintenance of the inner hole of the steel tapping hole simultaneously; under the function of the sleeve, the mending material forms regular cylindrical liquid steel channel in the inner hole of the steel tapping hole, thereby avoiding the problem that the mending material blocks the inner hole; the repairing and maintenance time can be shortened by more than 10 minutes every time, the repairing quality completely conforms to the requirements on steel tapping from the steel tapping hole, and smelting of the next time can proceed immediately after the inner hole of the revolving furnace is repaired.
Description
Technical field
The utility model belongs to converter steelmaking auxiliary facility field, particularly a kind of patcher that is used for mouthful maintenance in the tap hole.
Background technology
Before the steelwork converter steel tapping hole replacement, owing to mouthful be subjected to washing away of high-temperature molten steel for a long time in the tap hole, make in the tap hole through becoming big, the tapping time shortens, thereby the control difficulty of slag under the converter is strengthened; Simultaneously, because the shape of mouth becomes irregular in the tap hole, steel flow is dispersed under the gas effect, entrainments into obnoxious flavour easily, the harm steel quality; And along with dispersing that steel flows, it is big that the temperature drop of molten steel also becomes.The on-the-spot maintenance that need finish before programmed replacement in the tap hole mouthful mouthful is safeguarded in temporarily finishing in the short time so that be implemented in, and makes mouth in the tap hole satisfy the needs of tapping process.Yet, in the process in repairing tap hole mouthful, owing to there is not effective shutoff measure, execution conditions are relatively poor in addition, make after the repairing in mouthful molten steel channel irregular that becomes, sometimes even the phenomenon that causes mending material to stop up in the tap hole mouthful, prolonged the time of handling tap hole.
Summary of the invention
The purpose of this utility model aims to provide a kind of can be convenient in the tap hole and mouthful repairs, and shortens the tap hole maintenance time, makes the tap hole after the repairing satisfy the auxiliary repair apparatus that tapping requires.
The technical solution of the utility model is:
Mouthful auxiliary repair apparatus is made up of sleeve pipe, loudspeaker bucket, support and lacing wire in a kind of converter taphole.Telescopic one end is welded with the loudspeaker bucket, and sleeve pipe and loudspeaker bucket junction are provided with " ten " font support, and " ten " word point of crossing of support connects a lacing wire.
Described sleeve pipe is that wall thickness is the steel pipe of 2.5～3mm.
The beneficial effects of the utility model are:
The utility model from external orifice of steel-tapping hole insert and fixing after, can plough under mending material and carry out the body of heater repairing, finish maintenance simultaneously in the tap hole mouthful, under the telescopic effect, mending material is mouthful molten steel channel in the round shape tap hole of interruption-forming rule in the tap hole, has avoided the problem of mouth in the mending material obstruction, can shorten the repair maintenance time more than 10 minutes at every turn, and repairing quality has satisfied the requirement of tap hole tapping, the smelting that can drop into next stove immediately after mouthful repairing in the converter fully.
Description of drawings
Fig. 1 is a mouthful auxiliary repair apparatus structural representation in the converter taphole.
Fig. 2 is the right view of Fig. 1.
Among the figure: sleeve pipe 1, loudspeaker bucket 2, support 3, lacing wire 4.
Embodiment
As seen from Figure 1, the utility model is made up of sleeve pipe 1, loudspeaker bucket 2, support 3, lacing wire 4.By wall thickness is that the right-hand member head of the sleeve pipe 1 made of the steel pipe of 2.5～3mm welds a loudspeaker bucket 2, at the support 3 of sleeve pipe 1 with loudspeaker bucket 2 junctions welding one " ten " font, " ten " word point of crossing at support 3 connects a lacing wire 4 again, promptly is made for mouthful patcher in the converter taphole of the utility model.Fig. 2 can be more clearly visible the shape of " ten " font support 3.
Sleeve pipe 1 can use the converter taphole conduit peschel of thickening, and the tube wall thickening can avoid sleeve pipe 1 to produce distortion under high temperature action." ten " font support 3 that is welded with round steel in the sleeve pipe 1 mainly is to be used for supporting sleeve 1; The loudspeaker bucket 2 that has tapering can be fixed on the tap hole position with sleeve pipe 1, in order to avoid its skew.
Claims (2)
1, mouthful auxiliary repair apparatus in a kind of converter taphole is characterized in that, is made up of sleeve pipe, loudspeaker bucket, support and lacing wire; Telescopic one end is welded with the loudspeaker bucket, and sleeve pipe and loudspeaker bucket junction are provided with " ten " font support, and " ten " word point of crossing of support connects a lacing wire.
2, mouthful auxiliary repair apparatus in the converter taphole according to claim 1 is characterized in that described sleeve pipe is that wall thickness is the steel pipe of 2.5～3mm.
