Fig. 2 is a kind of schematic cross-sectional view of slag blocking dam of middle ladle with pod apertures baffle plate described in the utility model.
Specific embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment for being obtained, belongs to the scope of the utility model protection.
A kind of slag blocking dam of middle ladle with pod apertures baffle plate, it is characterised in that it includes dam body 1 and pod apertures
2 are nested with, wherein, the pod apertures are nested with 2 insertion dam bodies 1, and there are pod apertures 21 and pod apertures to stop steel for it
Plate 3.
Wherein, in the utility model, it is described before with defining below, be according to setting of such as getting off：Molten steel from
Impact zone flows to pouring area, then molten steel from before rear flow direction, accordingly, behind dam is after mounting, near the side of impact zone,
Before being near the side of plug hole, before described front also refers to.
The slag blocking dam of middle ladle with pod apertures baffle plate that the utility model is provided, its pod apertures 21 are embedded using pod apertures
The form of set 2, and be prepared from using more erosion resistant refractory material, it is less likely to occur to corrode, and helps to maintain and leads
The shape of discharge orifice, reduces the change of molten steel flow field so that during the use up to a few hours to ten a few houres, in tundish
Liquid steel temperature distribution separates holding stabilization with Impurities of Molten Steel.In addition, pod apertures stop the setting of steel plate, can cause applying
The molten steel that stage beginning contains impurity flows to pouring area by pod apertures.In this way, be nested with stopping steel with pod apertures by pod apertures
Plate can more effectively keep the separation of steel impurities in water, reduce and separate not good enough molten steel inflow pouring area.
Wherein, in a kind of specific embodiment, the dam body 1 uses magnalium fire resistant materials, the water conservancy diversion
Hole is nested with 2 corundums crossed using high-temperature process or refractory magnesia-alumina material.Certainly, when the utility model is implemented, ability
Field technique personnel can be certain using with other conventional materials making dam body, these conventional materials such as Magnesia-carbon material,
High aluminium material etc., there is extensive application in the prior art, also there is a large amount of descriptions in prior art literature, and this is no longer given this
To be discussed in detail.It is nested with for pod apertures, it uses more erosion resistant refractory material, these materials to be also classified into many kinds,
A large amount of descriptions and the extensive application in reality technology in the patent literature, those skilled in the art can very easily make choosing
Select.
Wherein, in a kind of concrete application, the pod apertures stop that steel plate 3 is arranged on the rear side of pod apertures 2, apart from water conservancy diversion
Hole is nested with 0~10mm of trailing flank.In this way, the initial period of tundish addition molten steel can thought, pod apertures stop that steel plate can
Outer or nearer apart from the pod apertures trailing flank position of pod apertures is blocked in by molten steel, is reduced that these are initial as far as possible, not yet had
The molten steel for imitating removal of impurities is polluted into pod apertures or to pod apertures.With continuing for molten steel and connecing for pod apertures stop steel plate
Touch, the stop steel plate can gradually melt and will open pod apertures, now, the molten steel that pod apertures after-opening brings out have been obtained for compared with
Good impurity is separated.
Wherein, in a kind of concrete application, the pod apertures stop that the thickness of steel plate 3 is 10~30mm.Certainly, at other
In concrete application, size that those skilled in the art can reasonably according to tundish and the height of dam adjust pod apertures
Stop the thickness of steel plate, it is however generally that, tundish is bigger, and dam is higher, and pod apertures stop that the thickness that steel plate is allowed is bigger,
Vice versa.
Wherein, in a kind of concrete application, the pod apertures stop that the periphery insertion pod apertures of steel plate 3 are nested with 2, embedding
The depth for entering is 5~30mm.The pod apertures stop that the depth that steel plate is embedded in during pod apertures are nested with should not be too deep, otherwise, with
The thawing of steel plate, the new corrosion pitting that the position that it is vacated can be nested with as pod apertures increases what pod apertures were nested with
Corrode, this aspect may result in molten steel flow field etc. and change, on the other hand, this may result in, and to be dissolved into molten steel total
Heteroion increases, and this can produce influence to the quality of steel in some cases.
Wherein, in a kind of concrete application, the rear end area of the pod apertures 21 is more than front end area, and its rear end is apart from pushing off the slag
The height of dam body bottom surface is less than the preceding height spent apart from dam body bottom surface.In this way, pod apertures can be facilitated to be nested with system
It is standby.
Wherein, in a kind of concrete application, the pod apertures are nested with multiple, in this way, just can be on dam
Multiple pod apertures are set, and then adjust molten steel flow field and Temperature Distribution in whole tundish.
Wherein, in a kind of concrete application, the inside of the dam body 1 sets bar-mat reinforcement, the bar-mat reinforcement distance gear
The side of slag dam body is at least apart from 10mm.And, the dam body can also thereon side set two mutually it is right
Claim suspension ring, the fixed reinforcing bar that bar-mat reinforcement is connected is arranged in suspension ring.In this way, the intensity of whole dam can be lifted, improve
Its yield rate and final product quality, facilitate it to transport and install.
Wherein, in a kind of concrete application, the pod apertures stop that the shape of steel plate is identical with pod apertures cross sectional shape, with
Just extra steel plate is reduced as far as possible, reduces the erosion space formed after the steel plate melts.
The above, specific embodiment only of the present utility model, but protection domain of the present utility model do not limit to
In this, any those skilled in the art in technical scope disclosed in the utility model, the change that can be readily occurred in
Change or replace, should all cover within protection domain of the present utility model.Therefore, protection domain of the present utility model should be with described
