Description
Technical field
The utility model relates to a kind of slag scraper of converter oxygen lance, belong to metallurgy industry converter oxygen gun equipment technical field.
Background technique
Converter is equipped with a set of slag scraper, is mounted on above converter platform oxygen rifle insert port.In converter steelmaking process, scrape
Can slag device effectively scrape the use that slag directly influences oxygen rifle.
Currently, the slag scraper that converter uses is pushed when finishing blowing mentions rifle by cylinder for rigid oxygen rifle slag-scraper
Scraping slag trolley drives dreg scraper knife head to travel forward, and cylinder stop motion, oxygen rifle starts to scrape slag.In actual production, due to oxygen rifle
Dry slag steely is more, and dreg scraper knife head portrait chock is caused equally to be wedged in steel slag, and oxygen rifle does not increase, is unable to come down, and dreg scraper knife head also moves back
It does not go out, causes card rifle accident.At this point, dreg scraper knife head destructiveness can only be sliced off, forms multiple conticaster and pull down accident, because
This, this slag scraper can only be forced to deactivate.After slag scraper deactivates, each furnace seat of per tour averagely changes oxygen rifle twice, every oxygen rifle
Replacement needs 3 hours, increases the labour that maintenance worker changes rifle and direct labor's oxygen rifle slag hitting, upper and lower oxygen rifle are had bad luck significantly
Intensity, and seriously threatened normal production.
Utility model content
The utility model aim is to provide a kind of slag scraper of converter oxygen lance, can be avoided oxygen rifle and occurs card rifle thing when scraping slag
Therefore solve the problems, such as background technique.
The technical solution of the utility model is:
A kind of slag scraper of converter oxygen lance includes the identical oxygen rifle slag-scraper of two structures, the identical oxygen rifle of two structures
Slag-scraper is arranged symmetrically in the two sides of oxygen rifle, and the oxygen rifle slag-scraper includes pedestal, cylinder, connecting rod, dreg scraper knife head, branch
Strut one and support rod two, cylinder is fixed on the base, and one end of connecting rod and the cylinder rod end of cylinder connect, the other end of connecting rod with
The connection of dreg scraper knife head, one end of support rod one and support rod two is hinged with pedestal respectively, support rod one and support rod two it is another
End is respectively hinged on connecting rod, and the hinge joint of support rod one and connecting rod is close to the cylinder rod end of cylinder, the hinge of support rod two and connecting rod
Contact is close to dreg scraper knife head.
Connecting rod in the oxygen rifle slag-scraper includes connecting rod one and connecting rod two, one end of connecting rod one and the cylinder rod end of cylinder
Connection, the other end of connecting rod one are connect with one end of connecting rod two, and the other end of connecting rod two is connect with dreg scraper knife head.
The support rod one is hinged on the tie point at connecting rod one and cylinder cylinder rod end, support rod two be hinged on connecting rod one with
On the tie point of connecting rod two.
The nearly oxygen rifle of dreg scraper knife head rest in the oxygen rifle slag-scraper.
Using the utility model, connecting rod is pushed under the promotion of cylinder and is scraped in the case where support rod one and support rod two are acted on
Slag cutter head is moved to oxygen rifle direction, when cylinder piston rod whole process is stretched out, scraping in the identical oxygen rifle slag-scraper of two structures
Opening degree between slag cutter head just starts to scrape slag at the position for being greater than oxygen rifle diameter.When in slag steel content it is larger scrape it is motionless
When, dreg scraper knife head reaction force is greater than the thrust of cylinder, and the gas in cylinder is compressed, and dreg scraper knife head, which is drawn back, to be allowed, and is successfully kept away
The generation of card rifle accident is exempted from.
The beneficial effects of the utility model are: having the function of to make a concession, it can be avoided oxygen rifle and occur card rifle accident when scraping slag.
Detailed description of the invention
FIG. 1 is a schematic structural view of the utility model；
Fig. 2 is utility model works process schematic；
In figure: leading pedestal 1, cylinder 2, connecting rod 3, dreg scraper knife head 4, support rod 1, support rod 26.
Specific embodiment
Below in conjunction with attached drawing, by example, the utility model is described in further detail.
Referring to attached drawing 1, a kind of slag scraper of converter oxygen lance includes the identical oxygen rifle slag-scraper of two structures, two structures
Identical oxygen rifle slag-scraper is arranged symmetrically in the two sides of oxygen rifle, the oxygen rifle slag-scraper include pedestal 1, cylinder 2, connecting rod 3,
Dreg scraper knife head 4, support rod 1 and support rod 26, cylinder 2 are fixed on pedestal 1, one end of connecting rod 3 and the cylinder rod end of cylinder 2
Connection, the other end of connecting rod 3 are connect with dreg scraper knife head 4, and one end of support rod 1 and support rod 26 is hinged with pedestal 1 respectively,
The other end of support rod 1 and support rod 26 is respectively hinged on connecting rod 3, and the hinge joint of support rod 1 and connecting rod 3 is close to gas
The hinge joint of the cylinder rod end of cylinder 2, support rod 26 and connecting rod 3 is close to dreg scraper knife head 4.
In the present embodiment, the identical oxygen rifle slag-scraper of two structures is mounted in converter platform oxygen rifle insert port
Side, is arranged symmetrically in the two sides of oxygen rifle.Wherein connecting rod 3 includes two 3-2 of one 3-1 of connecting rod and connecting rod, one end of one 3-1 of connecting rod and gas
The cylinder rod end of cylinder 2 connects, and the other end of one 3-1 of connecting rod is connect with one end of two 3-2 of connecting rod, the other end of two 3-2 of connecting rod with scrape
Slag cutter head 4 connects, and support rod 1 is hinged on one 3-1 of connecting rod and the tie point at 2 cylinder rod end of cylinder, 26 company of being hinged on of support rod
On the tie point of one 3-1 of bar and two 3-2 of connecting rod, dreg scraper knife head 4 is close to oxygen rifle.
Referring to attached drawing 2, dotted portion is after cylinder stretches out, and dreg scraper knife head scrapes scoriform state.When cylinder 1 works, connecting rod 3 is being propped up
Under strut 1 and support rod 26 act on, and dreg scraper knife head 4 is pushed to move to oxygen rifle direction under the promotion of cylinder 1, when cylinder 1
When piston rod whole process is stretched out, the opening degree between dreg scraper knife head 4 in the identical oxygen rifle slag-scraper of two structures is just big
Start to scrape slag at the position of oxygen rifle diameter 20mm.When steel content is larger in slag scrapes motionless, 4 reaction force of dreg scraper knife head is greater than
The thrust of cylinder 1, the gas in cylinder 1 are compressed, and dreg scraper knife head 4, which is drawn back, to be allowed, and the generation of card rifle accident is successfully avoided.
