Until pouring material does not generate bubble；
S5, pouring material is stood naturally, loose tool is removed after its solidification forming；
S6, continue nature standing pouring material, until the moisture in pouring material fully evaporates.
Preferably, in step sl, the fixing piece is the steel plate in circular ring shape, and the fixing piece is welded on the method
On blue inner wall.
Preferably, the fixed plate of vertical display is set on the fixing piece, and the bottom of the fixed plate is welded on described
On fixing piece, the side of the fixed plate is welded on the inner wall of the flange.
Preferably, in step s3, by connecting plate by two semicircle core assemblies connection composition loose tools and by loose tool
It is placed on residue pile.Preferably, in step s 5, pouring material stands 8 hours or more naturally, is torn open after pouring material solidification forming
Except loose tool.
Preferably, in step s 6, wait for that pouring material stands 15 hours or more naturally, until the moisture in pouring material fully steams
Hair.
As described above, the steel ladle opening one-piece casting of resistance to material technique of the present invention, has the advantages that：1, ladle
The method that the resistance to material of packet mouth uses one-piece casting, forms one layer of firm protective layer of resistance to material, it is ensured that steel on steel ladle opening flange
Packet safe handling；2, ladle flange is protected by pouring material, greatly reduces the repair cost of flange；3, one-piece casting material is logical
The anchoring piece for crossing welding forms an entirety, is not easy to peel off, avoids the waste of resistance to material, saves resistance to material cost.

Specific implementation mode
Illustrate that embodiments of the present invention, those skilled in the art can be by this explanations by particular specific embodiment below
Content disclosed by book understands other advantages and effect of the present invention easily.
It should be clear that structure, ratio, size etc. depicted in this specification institute accompanying drawings, only coordinating specification to be taken off
The content shown is not limited to the enforceable qualifications of the present invention so that those skilled in the art understands and reads, therefore
Do not have technical essential meaning, the modification of any structure, the change of proportionate relationship or the adjustment of size are not influencing the present invention
Under the effect of can be generated and the purpose that can reach, it should all still fall and obtain the model that can cover in disclosed technology contents
In enclosing.Meanwhile in this specification cited such as "upper", "lower", "left", "right", " centre " term, be merely convenient to chat
That states is illustrated, rather than to limit the scope of the invention, relativeness is altered or modified, and skill is being changed without essence
It is held in art, when being also considered as the enforceable scope of the present invention.
As shown in Figures 1 to 4, the present invention provides a kind of steel ladle opening one-piece casting of resistance to material technique, includes the following steps：
S1, fixing piece 2 is set in the top of the residue pile 1 of steel ladle opening, the fixing piece 2 is welded on steel ladle opening
On flange 3, the fixing piece 2 is generally made of the steel plate of circular ring shape, and the periphery of steel plate is welded on the inner wall of the flange 3
On, it is ensured that the fixing piece 2 will not be fallen from the inner wall of flange 3；
S2, the multiple anchoring pieces of top uniform welding in the fixing piece 2, make multiple anchoring pieces be arranged in and wait pouring
Region, multiple anchoring pieces can form frame structure, can connect into an entirety after so that pouring material 5 is poured by anchoring piece,
Anchoring enhances the connection of pouring material 5 and anchoring piece, and the two can be kept resistance to material whole more secured, be not easy to take off with shared stress
It falls；
S3, loose tool 4 above residue pile 1 is set, makes between the loose tool 4 and the fixing piece 2 that there are spacing, convenient for pouring
Build the filling of material 5；
S4, pouring material 5 is poured between the loose tool 4 and the flange 3 poured, while being shaken using vibrator close
Real, until pouring material 5 does not generate bubble, pouring material 5 need to use high temperature resistant material, prevent during later stage ladle transports molten steel
There is peeling phenomenon；
S5, it waits for that pouring material 5 stands a period of time naturally, until removing loose tool 4 after its solidification forming, prevents damage pouring material
5 shape；
S6, continue naturally to stand pouring material 5, until the moisture in pouring material 5 fully evaporates the baking that can just reach the standard grade.
As shown in Figures 1 to 4, it is preferable that the fixed plate 21 of vertical display, the fixation are set on the fixing piece 2

It is connected, the fixing piece 2 is embedded in the inside of pouring material 5, it is ensured that pouring material 5 will not peel off, and the fixed plate 21 is shared
Active force of the pouring material to the fixing piece 2, further ensures that pouring material 5 will not peel off.
As shown in Figures 1 to 4, it is preferable that in step s3, reinforcing rib, reinforcing rib can be vertically arranged on the loose tool 4
43 reinforce the intensity of the loose tool 4, it is ensured that the loose tool 4 will not deform, and the loose tool 4 is circularized by two 41 groups of core assemblies
Structure, loose tool 4 by two connection of core assemblies 41 composition loose tools 4 and is placed on by connecting plate 42 by residue pile when installation
On.
Preferably, in step s 5, pouring material 5 stands 8 hours or more naturally, and tire is removed after 5 solidification forming of pouring material
Pouring material 5 is stood 12 hours by mould 4 naturally in embodiment, and the intensity of forming is preferable, removes loose tool 4, pouring material 5 at this time
Shape will not change.Preferably, in step s 6, wait for that pouring material 5 stands 15 hours or more naturally, until pouring material 5
In moisture fully evaporate, in the present embodiment loose tool 4 remove after, pouring material 5 stands 16 hours naturally, the water in pouring material 5
Divide fully evaporation, at this time can reach the standard grade ladle baking.
A kind of embodiment of the present invention is given below：
The width of fixing piece 2 is 200mm, and the length of fixed plate 21 is 200mm, is highly 80mm, two neighboring fixed plate
Spacing between 21 is 450mm, and the height of pouring material 5 is 175mm on residue pile；The ring width of loose tool 4 is 150mm, height
230mm, diameter 4214mm, thickness 20mm, the thickness 20mm of connecting plate 42, length 210mm, width 150mm；The length of reinforcing rib 43
Spend 120mm, height 150mm.
In conclusion the present invention effectively overcomes various shortcoming in the prior art and has high industrial utilization.
The above-described embodiments merely illustrate the principles and effects of the present invention, and is not intended to limit the present invention.It is any ripe
