According to the converter oxygen lance buffer device, the fixed oxygen lance buffer is designed into the lifting movable buffer device, an oxygen lance trolley can descend to a mechanical lower exceeding limit under the buffers, so that the oxygen lance has better effects of slag splashing converter protection, and the problem that rising of the bottom of a converter is frequently resulted in when the converter carries out the operation of slag splashing converter protection is resolved.
Description
Technical field
The utility model relates to the snubber assembly of the oxygen lance lifting limit in a kind of convertor steelmaking process, particularly a kind ofly can by telescopic moving to change the snubber assembly of oxygen rifle working stroke, belong to the converter steelmaking equipment technical field.
Background technology
At present aborning; the anti-falling device for oxygen lance great majority of converter steelmaking are fixed snubber; if to be the oxygen rifle occur after the lower limit when out of control; snubber will be withstood in oxygen rifle dolly lower surface; guarantee that oxygen lance blow head is more than the molten steel face this moment; do not insert in the molten steel to play protection rifle head, avoid the rifle first melt after water coolant enter the effect that converter is blasted.But this fixed snubber is restricted the lower limit of oxygen rifle when splashing slag in converter, and it is lower that the oxygen rifle can not be dropped to.The workman of production scene and technician wish can make the oxygen rifle when carrying out the slag splashing operation through improving, snubber can change oxygen rifle working stroke, the rifle position further reduces when making slag splashing, the slag effect is better spattered in performance, reaching the purpose that prolongs the converter lining life-span and control better the type of furnace, and often cause that the difficult problem of furnace bottom rising is solved when making converter carry out the slag splashing operation.
The utility model content
Technical problem to be solved in the utility model provides a kind of converter oxygen gun snubber assembly, this device can solve because fixed bumper makes the oxygen rifle when carrying out the slag splashing operation, the rifle position can not further reduce, and often makes the furnace bottom rising problem when causing converter to carry out the slag splashing operation.
The technical scheme that solves the problems of the technologies described above is:
A kind of converter oxygen gun snubber assembly, it comprises fixed bumper, cross moving track, traversing framework, cylinder, its improvements are, it has also increased the upper end that mobile cushioning device, mobile cushioning device are installed in fixed bumper, the mobile cushioning device is comprised of the traversing framework in outside and intermediate column, one side of traversing framework is installed on the exterior side wall of intermediate column, the opposite side of traversing framework is fixed on the oxygen rifle fixed guide bearing by cylinder, and the mobile controller of mobile cushioning device is connected with converter PLC.
Above-mentioned converter oxygen gun snubber assembly, described cross moving track are positioned at two outsides of traversing framework, and traversing framework wheel is installed on the traversing framework, and traversing framework wheel is embedded in the cross moving track.
Usefulness of the present utility model is:
The utility model with fixed oxygen rifle buffer design become can reduction portable snubber assembly, the reduction action of mobile cushioning device and oxygen rifle smelting operation pattern interlocking, under the slag splashing pattern, PLC controls automatically by converter, make mobile cushioning device automatic retraction, the working stroke that the oxygen rifle is moved downward further prolongs, oxygen rifle dolly can be down to the position of transfiniting under the machinery below the snubber, with the better slag splashing effect of performance oxygen rifle, reach the purpose that prolongs the converter lining life-span and control better the type of furnace, the most important thing is that a difficult problem that makes converter often cause furnace bottom rising when carrying out the slag splashing operation is solved.
Description of drawings
Fig. 1 is structure of the present utility model and working state schematic representation;
Fig. 2 is another kind of working state figure of the present utility model;
Fig. 3 is the vertical view of Fig. 1.
Mark is as follows among the figure: intermediate column 1, cross moving track 2, traversing framework wheel 3, cylinder 4, fixed bumper 5, traversing framework 6, cylinder supports 7.
Embodiment
The utility model is comprised of intermediate column 1, fixed bumper 5, cross moving track 2, traversing framework 6, cylinder 4.
Show among the figure that the mobile cushioning device is comprised of the traversing framework 6 in outside and intermediate column 1.The intermediate column 1 of mobile cushioning device is installed in the upper end of fixed bumper 5, and a side of traversing framework 6 is installed on the exterior side wall of intermediate column 1, and the opposite side of traversing framework 6 is fixed on the oxygen rifle fixed guide bearing by cylinder 4.On the traversing framework 6 of mobile cushioning device pulley and slide rail are set.
Show among the figure that a side of traversing framework 6 is installed on the exterior side wall of intermediate column 1, traversing framework 6 can move forward and backward with intermediate column 1.Cross moving track 2 is positioned at two outsides of traversing framework 6, and traversing framework wheel 3 is installed on the traversing framework 6, and traversing framework wheel 3 is embedded in the cross moving track 2.
Show among the figure that the mobile cushioning device adopts cylinder 4 as the reduction propulsion source, cylinder 4 one ends are fixed on the oxygen rifle fixed guide bearing, and the other end is connected to the mobile cushioning device, and the mobile controller of mobile cushioning device is connected with converter PLC.The reduction action of mobile cushioning device and oxygen rifle smelting operation pattern interlocking, under the slag splashing pattern, PLC controls automatically by converter, makes mobile cushioning device automatic retraction, the working stroke that the oxygen rifle is moved downward further prolongs, and oxygen rifle dolly can be down to the position of transfiniting under the machinery below the snubber.
Working process of the present utility model:
When making steel when spattering slag operation, PLC controls automatically by converter, make cylinder 4 automatic retractions, drive the track of advancing that mobile cushioning device 1 leaves oxygen lance lifting bogie by traversing framework 6, oxygen lance lifting bogie can be down to the position of transfiniting under the oxygen rifle of fixed bumper 5 upper surfaces, when this moment, the oxygen lance blow head physical location was in steel-making blowing pattern, about the following 500mm of liquid steel level, with the better slag splashing effect of performance oxygen rifle, to reach the purpose that prolongs the converter lining life-span and control better the type of furnace, the most important thing is that a difficult problem that makes converter often cause furnace bottom rising when carrying out the slag splashing operation is solved.
When steel-making blowing pattern, PLC controls automatically by converter, makes mobile cushioning device auto-extending, and the working stroke that the oxygen rifle is moved downward recovers normal, makes converter when normal steel-making blowing, guarantees that the oxygen rifle can not enter below the liquid steel level, causes security incident.Mobile cushioning device 1 auto-extending, oxygen lance lifting bogie can only be down to the oxygen rifle lower limit of mobile cushioning device 1 upper surface, and this moment, oxygen lance blow head was in 200mm on the molten steel face, had both made the oxygen rifle out of control, and shower nozzle can not insert molten steel yet, causes explosion hazard.
Because the utility model makes again converter often cause that when carrying out the slag splashing operation difficult problem of furnace bottom rising is solved on the basis of the basic role of playing anti-block rifle pendant rifle accident, therefore has wide promotion prospect.
