Abstract
The utility model discloses a centering device for a slide block and a metering upper nozzle of a tundish of a small square billet. The centering device comprises a centering support rod, an anti-slip spacer and a hexagonal locking nut, wherein the centering support rod is used for ensuring the centering of the metering upper nozzle and the center aperture of the slide block, the anti-slip spacer and the hexagonal locking nut fix the centering support rod, after the installation is completed, the anti-slip spacer and the hexagonal locking nut are disassembled, and the centering support rod drops from the metering nozzle and the aperture of the slide block under the action of deadweight. The utility model solves the problem that the metering upper nozzle and the slide block are eroded fast by molten steel swirling flow caused by large centering deviation of the metering upper nozzle and the slide block of the tundish, accidents of molten steel leak between the slide block and the metering upper nozzle is prevented, and meanwhile, the centering device has the advantages of being low in use cost, convenient to install and the like.
Description
Technical field
The utility model relates to metallurgy industry continuous casting production technical field, particularly a kind of continuous small-billet casting tundish sizing filling pipe end and slide block installation centralising device of being adapted to.
Background technology
What each steel mill generally used at present is used as sizing filling pipe end and quick change slide block without the little billet tundish nozzle device of stopper, between them is to press by the face that the parts spring provides to combine, but has following problem:
1) tundish sizing filling pipe end is installed in the tundish, and aperture and position immobilize.Water in order to guarantee that conticaster leaves smoothly, the installation slide block uses first the small-bore slide block to open and waters, and opens to water successfully to change the large aperture slide block that mates with the sizing filling pipe end into by hydraulic cylinder afterwards;
2) small-bore being installed opens and waters slide block and observe centering by eyes, if slide block and sizing filling pipe end Disalignment deviation are difficult to more greatly observe out, open water successfully change afterwards the large aperture slide block after, sizing filling pipe end and slide block deviation are larger, cause molten steel not flow down smoothly by metering nozzle and slide block, form eddy current at metering nozzle and slide block place easily, metering nozzle and slide block are corroded seriously, cause when serious and wear the steel accident between sizing filling pipe end and slide block.
The utility model content
The utility model provides a kind of little square billet tundish sizing filling pipe end and slide block centralising device for the deficiencies in the prior art.
This device is comprised of centering pole 3 and hexagonal lock screw 1, and wherein, centering pole 3 is comprised of the Metallic rod of strap bolt, and it comprises three sections of upper, middle and lowers, and pole top is bolt arrangement, and pole middle part length is slightly larger than or equals the length in slide block 4 apertures.Centering pole 3 tops are bolt, centering pole 3 middle part diameters are slightly less than slide block aperture, small-bore, centering pole 3 lower diameter are slightly less than sizing filling pipe end 5 apertures, those skilled in the art are flexible design and select centering pole 3 as required, such as centering pole 3 upper bolt diameters than the little 0.5mm in slide block 4 apertures, centering pole 3 middle part diameters are than the little 0.5mm in slide block 4 apertures, and centering pole 3 lower diameter are than the little 0.5mm in sizing filling pipe end 5 apertures.
Optionally, described device also comprises anti-slip pad 2.
In that being installed, sizing nozzle of tundish and small-bore open when watering slide block, use this device can guarantee the centering of metering nozzle and slide block 4, using hexagonal locking nut 1, anti-slip pad 2 is that centering pole is dropped in the aperture of metering nozzle and slide block 4 in order to prevent from slide block is installed.

The specific embodiment
Below in conjunction with structural representation of the present utility model and implementation result figure, the utility model is described in further details, it is only with explanation rather than the restriction done the application.
Embodiment 1:
As shown in Figure 1, a kind of little square billet tundish sizing filling pipe end and slide block centralising device are comprised of centering pole, hexagonal lock screw and anti-slip pad, and wherein centering pole comprises three sections of upper, middle and lowers, pole top is bolt arrangement, and pole middle part length is slightly larger than or equals slide block 4 aperture lengths.
The design parameter of this device is as follows:
The little square billet tundish sizing filling pipe end 5 aperture Ф 20mm of six machines, six streams, slide block 4 aperture Ф 14mm, length 70.5mm, the long 25mm of centering pole 3 upper bolts, centering pole 3 middle part diameter Ф 13.5mm, length 72mm, centering pole 3 lower diameter Ф 19.5mm, length 30mm, centering pole 3 diameters and sizing filling pipe end 5 apertures and slide block 4 aperture corresponding positions all shorten 0.5mm and make things convenient for centering and fine setting.Its front view and left view are as shown in Figure 3 and Figure 4.Anti-slip pad 2 diameters are greater than the aperture of slide block 4, for flat gasket and surfacing smooth.
As shown in Figure 2, sizing filling pipe end 5 is installed first during installation, insert centering pole 3 in the sizing filling pipe end apertures after 5 installations of sizing filling pipe end and overlap top shoe 4, install and put anti-slip pad 2 behind the slide block and then install hexagonal lock screw 1, finely tune slide block 4 this moment all around and guarantee centering, hexagonal lock screw 1 and anti-slip pad 2 under the dismounting after centering work is finished, centering pole 3 drop in sizing filling pipe end 5 and slide block aperture under the effect of self gravitation.Tundish sizing filling pipe end and slide block centralising device have guaranteed that sizing filling pipe end 5 and slide block aperture centering are intact.Open to water successfully afterwards with hydraulic cylinder the slide block in Ф 14mm aperture be replaced with the slide block in Ф 17mm aperture, guaranteed to change the slide block in Ф 17mm aperture after sizing filling pipe end 5 good with slide block 4 centerings.
In the present embodiment, also anti-slip pad can be set, utilize the method for this centralising device and said method similar.
