Abstract
The invention provides a feeding device capable of baking covering slags by utilizing waste heat of a tundish, which comprises a loading box, a baking box and a covering slag conveying pipeline. The feeding device is characterized in that the baking box is fixed on a tundish vehicle by a fixing frame; the covering slag conveying pipeline comprises a material supply pipeline and a feeding pipeline; the bottom of the loading box is communicated with the baking box by the material supply pipeline; the bottom of the baking box is connected with the feeding pipeline; and the feeding pipeline extends onto a crystallizer cover board. The feeding device has a simple structure, is low in investment, is convenient to maintain, is energy-saving and environmental-friendly, can sufficiently utilize radiation heat of the tundish of a continuous casting machine to carry out baking and automatic feeding on the covering slags and is suitable to popularize and use.
Description
Technical field
What the present invention relates to is a kind of auxiliary equipment of steel plant continuous casting process, especially a kind of charging gear that utilizes tundish waste heat baking covering slag.
Background technology
Covering slag to continuous casting operation carry out smoothly with the quality of continuous casting billet important effect is arranged.Covering slag leaves the moisture of understanding in the air in the absorbed air in increases water content; in casting cycle; moisture can make the conglomeration of protection ground-slag; affect the quality of strand and be easy to cause the strike-alarm of conticaster even cause the bonding steel leakage accident when serious; this just requires in advance covering slag to be toasted, and reduces its water content.
At present the apparatus for baking of covering slag has multiplely, and the heat that mostly utilizes the burning such as coal gas to produce toasts covering slag, not only to consume a large amount of coal gas and obtain needed heat, and equipment is complicated, the service equipment investment greatly; Tundish will give off a large amount of heats in the continuous casting working procedure in casting cycle, has formed high temperature, dry environment around the tundish, also this waste heat is not effectively utilized at present.This is the existing weak point of prior art.
Summary of the invention
Technical problem to be solved by this invention is exactly for the existing deficiency of prior art, and provides a kind of simple in structure, small investment, easy to maintenance, a kind of charging gear that toasts covering slag of energy-saving and environmental protection.This scheme can take full advantage of the amount of heat that the tundish in the continuous casting working procedure gives off covering slag is toasted drying and autofeed, does not need the auxiliary of other equipment fully, good energy-conserving effect.
This programme is achieved by the following technical measures: described a kind of charging gear that utilizes tundish waste heat baking covering slag; comprise feeding box, baking box and covering slag conveying pipeline; the characteristics of this scheme are: described baking box is fixed on the tundish car by fixed mount; described covering slag conveying pipeline comprises feed pipeline and feed pipeline; the bottom of described feeding box is communicated with by feed pipeline and described baking box; described baking box bottom is connected with the feed pipeline, and this feed pipeline extends on the crystallizer cover plate.
The concrete characteristics of this scheme are: be provided with a grid that is parallel to horizontal plane in the described feeding box.
Described feeding box be shaped as funnel-form.
In the described feed pipeline control valve is installed.
Technical characterstic of the present invention and good effect:
1, simple in structure, mainly formed small investment and non-maintaining by steel plate and steel-pipe welding;
2, energy-conserving and environment-protective.This device is welded on the tundish car, can directly utilize the tundish waste heat that covering slag is toasted, and has saved the consumption of the baking energy;
3, cured effect is good.Guarantee the covering slag thermally equivalent in the baking box, conglomeration, caking and the decarburization phenomenon of covering slag when having avoided the flame baking is arranged;
4, utilize covering slag self gravitation and the mobile feed of realizing, need not power, reach energy-conservation purpose.
This shows that the present invention compared with prior art has outstanding substantive distinguishing features and significant progressive, the beneficial effect of its enforcement also is apparent.
Description of drawings
Fig. 1 is the structural representation of the specific embodiment of the invention.
Among the figure, 1 is grid, and 2 is feeding box, and 3 is the feed pipeline, and 4 is baking box, and 5 is fixed mount, and 6 is the feed pipeline, and 7 is control valve, and 8 is covering slag, and 9 is the crystallizer cover plate.
The specific embodiment
For clearly demonstrating the technical characterstic of this programme, below by a specific embodiment, and in conjunction with its accompanying drawing, this programme is set forth.
Can find out by accompanying drawing; described a kind of charging gear that utilizes tundish waste heat baking covering slag; include feeding box 2; baking box 4 and covering slag conveying pipeline; described baking box 4 is fixed on the tundish car by fixed mount 5; whole device can move to the casting position with tundish; by overhead traveling crane covering slag is winched to the large bag platform of casting machine; the covering slag 8 that needs use is poured in the feeding box 2; the bottom of feeding box 2 is communicated with by feed pipeline 3 and baking box 4; the funnel shaped of feeding box 2 is easy to covering slag 8 and flows in the baking box 4 by feed pipeline 3, and the grid 1 in the feeding box 2 can prevent that the covering slag 8 of foreign matter and caking from entering in the baking box 4 simultaneously.The baking box 4 that fills covering slag 8 utilizes the waste heat of tundish radiation to toast in the environment of high temperature, drying two hours; baking box 4 bottoms are connected with feed pipeline 6; delivery rate after control valve 7 is regulated covering slag 8 bakings is installed in the feed pipeline 6; only need open the control valve 7 on the feed pipeline 6 when needing protection slag 8, the covering slag 8 after the baking flow on the crystallization cover plate 9 by feed pipeline 6 under Action of Gravity Field.
The present invention is not limited in the above-mentioned specific embodiment, and the variation that those of ordinary skills make in essential scope of the present invention, remodeling, interpolation or replacement also should belong to protection scope of the present invention.
