Abstract
The utility model discloses a kind of converter oxygen gun self-locking centering slag scraper, above the two ends of its crossbeam, column is installed, the symmetrical inner side of column is all connected with crank A, one end of crank A and crank B is hinged, and hinged place connects the piston rod end of cylinder, the other end of cylinder is fixed on the top of column; The other end of crank B is connected with one end of knife rest, and knife rest is loaded in saddle, and saddle is fixed on above crossbeam, and the other end of knife rest is connected with scraper.The utility model achieves " locking " function to blade, because being subject to resistance excessive and " opening " or " collapsing out " blade when scraping slag, or can not damage miscellaneous equipment; Blade fast changeable, does not affect continuous seepage; Achieve oxygen rifle centering positioning function.
Description
Technical field
The utility model belongs to oxygen lance for steel-making converter supplementary unit, and the slag scraper of slag on oxygen gun body is removed in the self-locking being specifically related to converter steelmaking converter oxygen gun to neutralization.
Background technology
Converter (top blast or top and bottom complex blowing) steel-making relies on oxygen rifle to insert in converter cavity volume, injected the molten iron in cavity volume, slag making materials by the oxygen in oxygen rifle, oxygen and molten iron occurs, the chemical reaction of slag making materials smelts.Converter steelmaking process can produce a large amount of slags, and the leaching of oxygen rifle is stagnant in slag, inevitably has slag and is attached on oxygen gun body, if remove slag on rifle body not in time, one is become hard after slag cooling to be more difficult to removal; Two is repeatedly adhere to postemphasis oxygen rifle weight and increase rifle body diameter to affect elevating function, increase machine utilization; Three is to affect smelting (metallurgy) effect; Four is to shorten oxygen rifle work-ing life.Therefore, removing slag on rifle body in time to oxygen rifle is basic demand.
Method on current removing oxygen gun body, comprising: artificial scarfing cinder and mechanical scarfing cinder two kinds.The labour intensity of artificial scarfing cinder is large, Working environment, poor stability, and working efficiency is not high, substantially not (suggestion) employing; Mechanical scarfing cinder is generally taked when smelting complete, and oxygen rifle proposes, in the uphill process of converter, to utilize the power risen, and employing blade strikes off the slag on rifle body.Clear (scraping) slag device of machinery is the device of a kind of unlatching, closedown, fixed blade, and utilize this device to be fixed to scraping slag position by blade movement, when oxygen rifle rises, the slag on rifle body moves to blade position, thus is removed by blade; Oxygen rifle leaves to be removed behind position, and device is opened blade to leave and scraped slag position; Because the consolidated form of equipment is different with manner of execution, it is different to scrape slag effect, and the life-span of equipment also respectively has not identical with repair density.
In addition, oxygen rifle inserts in converter cavity volume, due to the precision of oxygen lance lifting system and the impact of oxygen rifle oxygen, add it is fixed oxygen rifle end, oxygen rifle the other end head (head from end generally more than 15 meters, if 50 tons of converter oxygen gun length are more than 15 meters) stressed impact will be rocked, off normal, and the oxygen rifle (oxygen) departing from centre bit is like this smelted and certainly will be produced uneven the washing away, corrode of bof vessel inwall, have impact on direct motion and the converter lining life-span of production.For reducing the off normal during work of oxygen rifle, usually taking to improve oxygen lance lifting system equipment precision, also having plenty of, in way advanced by oxygen rifle, fixed guide fixed wheel is installed; But it is large to improve the investment of oxygen lance lifting system equipment precision, and arranges guide wheel in way advanced by oxygen rifle, is difficult to again find suitable installation site, or because of installation site inadequate, cause the guiding of guide wheel and locating effect bad.
Utility model content
The technical problem of solution described in the utility model is to provide a kind of oxygen rifle slag scraper, realize scraping slag and alignment function to oxygen gun body, both completed and slag effect had been scraped to oxygen rifle, substitute again the function that oxygen rifle fixed guide fixed wheel accomplishes centering oxygen rifle, oxygen rifle centering when scraping slag operation can not only be realized, oxygen lance location (to the meta) blowing of smelting process can also be realized; Scraping in slag process and can accomplish that to blade " locking " acts on simultaneously, avoiding the stressed bigger device of crossing of blade " to open " or " collapsing out " phenomenon; Blade adopts fast changeable mode in addition, affects continuous seepage with during free of replacement.
For achieving the above object, the utility model by the following technical solutions.Converter oxygen gun self-locking centering slag scraper, comprise crossbeam, it is characterized in that, above the two ends of described crossbeam, column is installed, the symmetrical inner side of column is all connected with crank A, one end of crank A and crank B is hinged, and hinged place connects the piston rod end of cylinder, and the other end of cylinder is fixed on the top of column; The other end of crank B is connected with one end of knife rest, and knife rest is loaded in saddle, and saddle is fixed on above crossbeam, and the other end of knife rest is connected with scraper.
The utility model advantage is, realizes " locking " function to blade, because being subject to resistance excessive and " opening " or " collapsing out " blade when scraping slag, or can not damage miscellaneous equipment; Blade fast changeable, does not affect continuous seepage; Smelt omnidistance realization oxygen rifle centering positioning function, for BOF steelmaking shop provides, a kind of equipment is stablized, diverse in function, respond well oxygen rifle slag scraper.
Accompanying drawing explanation
Fig. 1 is structural front view of the present utility model.
Fig. 2 is structure vertical view of the present utility model.
In figure: 1. column, 2. crossbeam, 3. cylinder, 4. crank A, 5. crank B, 6. knife rest, 7. saddle, 8. scraper, 9. oxygen rifle.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.See Fig. 1 and Fig. 2, converter oxygen gun self-locking centering slag scraper, comprise crossbeam 2, it is characterized in that, be provided with column 1 above the two ends of described crossbeam 2, the symmetrical inner side of column 1 is all connected with crank A4, and one end of crank A4 and crank B5 is hinged, and hinged place connects the piston rod end of cylinder 3, the other end of cylinder 3 is fixed on the top of column 1; The other end of crank B5 is connected with one end of knife rest 6, and knife rest 6 is loaded in saddle 7, and saddle 7 is fixed on above crossbeam 2, and the other end of knife rest 6 is connected with scraper 8.
embodiment:the utility model is that center line symmetry is installed on the both sides of oxygen rifle 9 with oxygen rifle 9, column 1 and crossbeam 2 make whole device long-time in working order time indeformable, not dystopy; Cylinder 3 is propulsion sources of device motion; Crank A4 and crank B5 and knife rest 6 refer to and realize the action of scraper 8 and the transmission of power, realize the location of dreg scraping unit part scraper 8; Saddle 7 is fixing and controls the parts of knife rest 6 sliding and running, and a general knife rest 6 is fixed by former and later two saddles 7, is convenient to that knife rest 6 slides in slip column, not off normal and fixed action; The blade of two scrapers 8 is equipped with in one end of each knife rest 6.
When oxygen rifle 9 rises, cylinder 3 piston rod be symmetrically fixed on the column 1 at crossbeam 2 two ends stretches out simultaneously, drive crank B5 and promote knife rest 6 and slide to oxygen rifle 9 direction, the hard-wired scraper 8 in knife rest 6 front end clips to the periphery of oxygen rifle 9, thus realize oxygen rifle 9 positioning function, complete simultaneously and scrape slag action.
