Abstract
The utility model relates to a gas curtain barricade with distributes continuous gas slots along the width direction, wherein a gas chamber and a plurality of gas slots which are used to communicate the gas chamber and the working surface of the gas curtain barricade are formed in the gas curtain barricade, wherein a plurality of gas slots are arranged along the width direction of the gas curtain barricade. The gas curtain barricade which is provided by the utility model has good gas washing effect and realizes the flexible control to gas flow more easily.
Description
Technical field
The utility model relates to the air curtain barricade wall that a kind of tundish metallurgy is used, and specifically is the air curtain barricade wall that a kind of broad ways is arranged continuous air cleft.
Background technology
In the continuous casting process, air curtain barricade wall is set in tundish usually, blows, come the temperature and the composition of molten steel in the even tundish, eliminate stagnant water, improve molten steel flow field, promote inclusion floating, thereby carry out tundish metallurgy effectively to tundish.Tundish air curtain barricade wall of the prior art mostly is bar shaped, be arranged at the tundish bottom along the tundish width, and the air cleft that is used for blowing to tundish normally is provided with one or several along the length direction of air curtain barricade wall.But, because the width of described air curtain barricade wall is limited, therefore the air cleft of its length direction setting of air curtain barricade wall upper edge can only be one or limited several usually, the shortcoming of negligible amounts and the very elongated maximum that air cleft brought is exactly like this: the gas that blows out is very thin one deck, direction is too outstanding, air-flow is very inhomogeneous, air purge and to improve the flow field effect bad.On the other hand,, be difficult for air-flow is controlled, influence the production efficiency and the quality of production because air cleft negligible amounts and very elongated is fierce in certain direction winding-up.
The utility model content
For this reason, technical problem to be solved in the utility model is to provide the air curtain barricade wall that a kind of air purge is effective, be easy to realize the broad ways of air-flow Flexible Control is arranged continuous air cleft.
For solving the problems of the technologies described above, the utility model is achieved through the following technical solutions:
A kind of broad ways is arranged the air curtain barricade wall of continuous air cleft, form air chamber in the described air curtain barricade wall and be communicated with described air chamber and the continuous air cleft of many non-interruptions of described air curtain barricade wall working surface, many described air clefts are along the width setting of described air curtain barricade wall.
The width range of described air cleft is 0.05mm-0.35mm.
On described air curtain barricade wall working surface, the setting parallel to each other of described air cleft.
On described air curtain barricade wall working surface, the spacing range of two adjacent described air clefts is 0.15mm-15mm.
The spacing of adjacent described air cleft equates.
Described air curtain barricade wall adopts cast or machine to suppress.
Technique scheme of the present utility model has the following advantages compared to existing technology: air curtain barricade wall 1. of the present utility model, continuous air cleft is arranged along its width, the air cleft of greater number can be set, because the quantity showed increased of air cleft and the distribution of air cleft more disperse, and the blow-off direction of gas is more disperseed, air-flow can more divergently blow to high-temperature molten steel, obviously improve molten steel flow field, promote inclusion floating, improve the clearance of field trash and harmful element, the air purge better effects if; 2. air curtain barricade wall of the present utility model, air cleft can be provided with the air cleft of greater number along the width setting of air curtain barricade wall, and because single air cleft is shorter, each air cleft ejection gas flow is less, and therefore easier realization is to the Flexible Control of air-flow; 3. air curtain barricade wall of the present utility model, on described air curtain barricade wall working surface, the spacing range of two adjacent described air clefts is 0.15mm-15mm, because the disperse function of blow gas from air cleft, therefore can on the length direction of described air curtain barricade wall, form continuously, thicker air curtain, make the temperature and the composition of the interior molten steel of tundish more even; 4. air curtain barricade wall of the present utility model, because the width of air cleft only is 0.05mm-0.35mm, the area of wall scroll air cleft is very little, molten steel is easy to leak not, therefore is difficult for saturating steel accident takes place, and can guarantee the safety of producing; 5. in addition, air curtain barricade wall of the present utility model adopts cast or machine to suppress, and is easy to manufacture.
Description of drawings
For the easier quilt of content of the present utility model is clearly understood, according to specific embodiment of the utility model also in conjunction with the accompanying drawings, the utility model is described in further detail, wherein below
Fig. 1 is the front view of air curtain barricade wall of the present utility model;
Fig. 2 is the vertical view of air curtain barricade wall of the present utility model;
Fig. 3 is the vertical view of the air curtain barricade wall of other embodiment of the utility model.
Reference numeral is expressed as among the figure: 1-air curtain barricade wall, 2-air chamber, 3-air cleft
The specific embodiment
To shown in Figure 2, the air curtain barricade wall 1 of present embodiment is bar shaped as Fig. 1, forms many continuous air clefts 3 of air chamber 2 and described air chamber 2 of connection and described air curtain barricade wall 1 working surface in the described air curtain barricade wall 1.Described air curtain barricade wall 1 adopts cast or machine to suppress, the convenient manufacturing.Many described air clefts 3 are uniformly laterally arranged along the width of the described air curtain barricade wall 1 of bar shaped, the spacing of two adjacent described air clefts 3 is 5mm, the quantity of described air cleft 3 is more, make gas can not only more disperse, blow to equably high-temperature molten steel, and can provide bigger mixing power, the air purge better effects if.Because the disperse function of blow gas from described air cleft 3, can on the length direction of described air curtain barricade wall 1, form continuously, thicker air curtain, make the temperature and the composition of the interior molten steel of tundish more even.The width of a fairly large number of each described air cleft 3 is 0.12mm, compare with a small amount of slit, a large amount of described air cleft 3 along described air curtain barricade wall 1 width setting, because single described air cleft 3 is shorter, the gas flow that each described air cleft 3 blows out is smaller, the Flexible Control of easier realization gas, the air purge better effects if.
In other embodiments, the width of described air cleft 3 can be 0.05mm, and the spacing of two adjacent described air clefts 3 is 15mm, can form continuous air curtain on the length direction of described air curtain barricade wall 1.Perhaps in other embodiments, the width of described air cleft 3 also can be 0.35mm, and the spacing of two adjacent described air clefts 3 is 0.15mm.Under the prerequisite that guarantees not bleed-out, safety in production, can realize bigger air-flow, bigger gas mixing power is provided.
Certainly, in other embodiments, on described air curtain barricade wall 1 working surface, described air cleft 3 can also as shown in Figure 3, can be realized effect of the present utility model equally along described air curtain barricade wall 1 width with the oblique setting of suitable angle.
Obviously, the foregoing description only is for example clearly is described, and is not the qualification to embodiment.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here need not also can't give exhaustive to all embodiments.And conspicuous variation of being extended out thus or change still are among the protection domain of the utility model creation.
