Description
Technical field
The utility model relates to a kind of device for removing the slag that the outer steel pipe of oxygen lance for steel-making converter adheres to, and belongs to metallurgical technology field.
Background technology
Oxygen rifle is one of major equipment of converter steelmaking, in blowing and slag splashing process, the outer steel pipe of oxygen rifle inevitably adheres to slag, will be more long-pending thicker if these slags can not be removed in time, oxygen rifle can not be normally elevated (namely can not propose oxygen muzzle), finally cause oxygen rifle to be scrapped, therefore oxygen rifle generally all will configure and scrape slag equipment.
Existing oxygen rifle is scraped slag equipment and is comprised two scraping slag arm and being arranged on each dreg scraper knife head scraped on slag arm by air cylinder driven.The Working environment scraping slag arm is extremely severe, and be easy in working process occur the problems such as cutter head damage, bearing pin distortion, therefore often needs change dregs scraper online.But be all independent installation, separately dismounting because existing two of scraping slag equipment scrape slag arm, and there is larger danger in disassembling operations, therefore the working efficiency of scraping slag arm is changed very low, particularly when scraping slag arm dry slag, distortion and being comparatively serious, consuming time more, repair time generally need take 4 ~ 5 hours, has had a strong impact on normally carrying out of STEELMAKING PRODUCTION.
Therefore, a kind of oxygen lance for steel-making converter dregs scraper being easy to change can be designed, save more times for producing, becoming the technical barrier that relevant technologies personnel are urgently to be resolved hurrily.
Utility model content
The purpose of this utility model is the drawback for prior art, provides a kind of Dreg Scraping Device of Oxygen Lance being convenient to change, and to improve the replacing efficiency of dregs scraper, ensures normally carrying out of STEELMAKING PRODUCTION.
Problem described in the utility model realizes with following technical proposals:
A kind of Dreg Scraping Device of Oxygen Lance being convenient to change, formation comprise scrape slag arm base, two scrape slag arm, two dreg scraper knife heads and two cylinders, describedly scrape the side of the base plate that slag arm base is fixed on oxygen rifle snubber, two head end symmetries of scraping slag arm are articulated with the two ends of scraping slag arm base, two dreg scraper knife heads lay respectively at the both sides of oxygen rifle and are separately fixed at the tail end that two are scraped slag arm, and the curved blade of the two is corresponding with the slag on converter oxygen gun outer steel pipe; The cylinder body of two cylinders is hinged on two two air cylinder bases scraped outside slag arm respectively, and their piston rod is hinged with two middle parts of scraping slag arm respectively.
The above-mentioned Dreg Scraping Device of Oxygen Lance being convenient to change, described slag arm base of scraping comprises rectangular base plate with two to being parallel to the long limit of rectangular base plate and the otic placode vertical with rectangular base plate, described rectangular base plate is fixed on the side of the base plate of oxygen rifle snubber by joint bolt, two pairs of otic placodes are symmetrically fixed on the two ends of rectangular base plate, two head ends scraping slag arm to be clipped in respectively between two pairs of otic placodes and by scrape slag arm bearing pin and otic placode hinged.
The above-mentioned Dreg Scraping Device of Oxygen Lance being convenient to change, the two ends of often pair of otic placode in described rectangular base plate are connected by the web plate perpendicular to otic placode, are provided with the stiffening web being parallel to the long limit of rectangular base plate at the middle part of rectangular base plate.
The above-mentioned Dreg Scraping Device of Oxygen Lance being convenient to change, described in scrape between slag arm bearing pin and the shaft hole inner wall of otic placode and be embedded with copper axle sleeve.
The utility model is scraped slag arm and is arranged on same base by two, when changing dregs scraper, scraping slag arm for two can dismantle with base and install, and so just substantially increases the replacing efficiency of dregs scraper, ensure that normally carrying out of STEELMAKING PRODUCTION.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is for scraping slag arm base vertical view;
Fig. 3 is for scraping slag arm base front view.
In figure, mark is as follows: 1, scrape slag arm base, and 2, scrape slag arm, 3, dreg scraper knife head, 4, joint bolt, 5, oxygen rifle snubber, 6, cylinder, 7, air cylinder base, 8, scrape slag arm bearing pin, 9, cylinder body bearing pin, 10, cylinder rod bearing pin, 11, otic placode, 12, web plate, 13, stiffening web, 14, pin-and-hole, 15, base plate.
Embodiment
It is few, easy to maintenance that the purpose of this utility model there is provided a kind of fault, can quick-replaceable slag scraper of converter oxygen lance.
Referring to Fig. 1 and Fig. 2, the utility model comprises to be scraped slag arm base 1, scrapes slag arm 2, dreg scraper knife head 3, joint bolt 4, oxygen rifle snubber 5, cylinder 6, air cylinder base 7, scrape slag arm bearing pin 8, cylinder body bearing pin 9, cylinder rod bearing pin 10.Wherein, air cylinder base 7 comprises the otic placode 11 on base plate 15 and top thereof, web plate 12 and stiffening web 13.
Whole dregs scraper is fixed on oxygen rifle nitrogen seal location, scrape slag arm base 1 and be fixed on oxygen rifle snubber 5 side of the base plate by joint bolt 4, scrape slag arm base 1 two ends equal to the distance of oxygen rifle, joint bolt 4 is high strength bolt, the both sides that slag arm 2 is positioned at oxygen rifle are scraped in both sides, they are scraped slag arm bearing pin 8 respectively by two and are arranged on and scrape slag arm base 1 two ends, so just by base (scraping slag arm base 1 and air cylinder base 7), cylinder 6 with scrape slag arm 2 and form a three-link mechanism.When the cutter head of dregs scraper damages or bearing pin distortion need change, scrape joint bolt on slag arm base 14 and can rapidly a whole set of dregs scraper be changed roll off the production line by removing and repair, substantially reduce the time changing dregs scraper.
Cylinder 6 is arranged on air cylinder base 7 by cylinder body bearing pin 9, and the piston rod of cylinder 6 is connected to by cylinder rod bearing pin 10 to be scraped on slag arm 2, scrapes slag arm 2 and is connected on base 1 by scraping slag arm bearing pin 8, promotes to scrape slag arm 2 carry out opening and closing movement by cylinder 6.Each dreg scraper knife head 3 is formed by connecting by three sections, and dreg scraper knife head 3 is arranged on by bolt to be scraped on slag arm 2, and base 1 is connected with oxygen rifle snubber 5 by 6 joint bolts 4.When dregs scraper need be changed, only cylinder rod bearing pin 10 need be removed, remove scraping 6 joint bolts 4 that slag arm base is connected with oxygen rifle snubber 5, lower a whole set of dregs scraper can be changed rapidly and carry out finishing of rolling off the production line.Scrape slag arm bearing pin 8 outer cover and copper axle sleeve is housed, otic placode 11 is high, solid and reliable with the bond strength scraping slag arm bearing pin 8, and easy accessibility, fault is few.
Use this dregs scraper, the online replacing construction of dregs scraper can shorten to 45 minutes by original 4 ~ 5 hours.
