Description
Technical field
The utility model relates to a kind of porous core outer mounting structure, belong to steel and iron industry equipment technical field, more particularly to outer
Dress formula porous core retaining mechanism.
Background technique
The ladle of existing steel-making would generally install porous core in bottom, can be passed through into ladle by the porous core of installation
Argon gas after argon gas enters in molten steel, is scattered in molten steel in the form of bubbles and floats, the molten steel of surrounding by buoyancy driving above
It is formed to upper stream, reaches backward horizontal direction rotation at the top of molten steel, then backflow downwards along steel ladle, make molten steel in ladle
Internal circulation flow, makes to add the rapid meltings such as alloy, the flux in molten steel with this, promote molten steel component and temperature it is uniform with
And in molten steel field trash floating, can remove steel in nonmetal inclusion and pernicious gas, achieve the purpose that refining liquid steel.
After porous core is mounted on ladle bottom (be commonly called as packet bottom), generally using metal hose by its be fixed on above ladle
The steel pipe connection with quick coupling, steel pipe with the metal hose of quick coupling with argon source again by connecting, by argon gas
Conveniently it is passed through in ladle.
There are two types of porous core mounting means common at present, is built-in type and fitted outside respectively, built-in type porous core is general
It is to form a whole with brick cup, and there are suspension hook, when installation is lifted on inside ladle；Fitted outside porous core is mounted in ladle
Portion, with packet bottom build simultaneously, when porous core using to a certain extent after, it is hot it is lower remaining porous core is got, outside ladle
Portion is loaded on new porous core.But when installing new porous core, often will appear porous core be aligned with brick cup not just,
The not in place or porous core periphery high-temperature flame-proof mud of porous core installation is unevenly distributed and wraps gap between bottom and fills up loosely, occurs
The safety accident that molten steel leaks in ladle.Therefore, how to ensure that the accurate replacement of fitted outside porous core is needed as refining liquid steel
It solves the problems, such as.
Summary of the invention
To solve the above technical deficiency, the utility model provides a kind of porous core outer mounting structure, can be in porous core
End by its it is reliable lock, avoid porous core from left and right, upper and lower shaking occur, and then avoid caused by shaking as porous core
The safety accident that high-temperature flame-proof mud is unevenly distributed, unevenness is filled up in gap, molten steel leaks.
The technical solution of the utility model is as follows: a kind of porous core outer mounting structure, including packet bottom, sets in the middle part of the packet bottom
There is porous core mounting hole, the two sides that porous core mounting hole is located on the packet bottom are equipped with vertical plate, and the vertical plate and packet dolly are straight, stand
Latch is provided on the outside of plate, latch is equipped with the vertical plate hole cooperated with vertical plate and the air hole with porous core cooperation, stands
The outside contacted on plate with latch is equipped with locking hole, is equipped with inclined wedge in the locking hole.
The technical solution of the utility model further include: the vertical plate include left risers on the left of the porous core mounting hole and
Right risers on the right side of porous core mounting hole, the right risers and left risers are horizontally disposed.
The technical solution of the utility model further include: the left risers and right risers are welded on packet bottom.
The technical solution of the utility model further include: the end of the left risers and right risers is equipped with assembly guiding and falls
Angle.
The beneficial effects of the utility model are: vertical plate is arranged in the two sides for being located at porous core mounting hole on packet bottom, using vertical
Plate makees latch and wraps the connection at bottom, and porous core is pushed into ladle after accurate location by latch, is packed on vertical plate oblique
Wedge is urgent by latch and packet bottom, so as to provide sufficiently reliable holding power to the porous core of replacement, porous core is avoided to be packed into
Occur left and right, upper and lower shaking afterwards, and avoid being aligned not as caused by shaking with brick cup just, porous core periphery high-temperature flame-proof
The safety accident that molten steel caused by mud filling chink is irregular leaks ensure that while quick and precisely completing porous core replacement
Safe normal use of the porous core in ladle.
Detailed description of the invention
Fig. 1 is the decomposition diagram of the utility model.
Fig. 2 is the assembling schematic diagram of the utility model.
In figure, 1, vertical plate, 2, porous core, 3, inclined wedge, 4, latch, 5, packet bottom.
Specific embodiment
Below in conjunction with attached drawing, by embodiment, the utility model is described in further detail.
As depicted in figs. 1 and 2, the porous core outer mounting structure of the utility model, is mainly used for the replacement of fitted outside porous core,
It is located at the vertical plate 1 of porous core two sides of mounting hole on packet bottom 5 including being arranged in.
The latch 4 being inserted in from 1 outside of vertical plate (side far from packet bottom 5), cooperation, it is equipped with and stands on latch 4
The matched vertical plate hole of plate 1, and, in order to use latch 4 to be accurately pushed into porous core 2, it is equipped on latch 4 ventilative
Hole.
It is located at the outside contacted with latch 4 on vertical plate 1 locking after latch 4 is inserted in vertical plate 1 equipped with locking hole
Inclined wedge 3 is packed into tieholen, it is using inclined wedge 3 that latch 4 and vertical plate 1 is urgent, and the urgent power can mention for the porous core 2 of replacement
For sufficiently reliable retentivity, avoids the porous core 2 or so of new clothes, teetertotters.In addition, designing, inclined wedge 3 is urgent to be applicable to
Inclined wedge 3 can be squeezed into deeper degree when ladle is larger by different size of ladle, only need to be by inclined wedge 3 when ladle is smaller
It shallowly squeezes into, to improve the versatility of the utility model outer mounting structure.
In the utility model, vertical plate 1 is horizontally set on to the left and right sides of porous core mounting hole, thus can facilitate inclined wedge 3
It is loaded vertically into, convenient for enhancing locking effect.Specifically, vertical plate 1 is welded on packet bottom 5, to improve global reliability.
In the utility model, in the end (namely outer end) of vertical plate 1, design has what can be play the guiding role in assembly to fall
Angle, to facilitate the quick and precisely loading of latch 4, to improve working efficiency.
The outer mounting structure of the utility model can fast and accurately adjust relative position of the porous core in brick cup, realize
The quick and precisely replacement of porous core, and can guarantee porous core in ladle safe normal use, it can be achieved that replace porous core online,
Realize continuous production.
The above is only the preferred embodiment of the utility model, not does limit in any form to the utility model
System, done any modifications, equivalent replacements, and improvements etc., should be included in this reality within the spirit and principle of the utility model
Within novel protection scope.
