Abstract
The utility model relates to a ladle cover for a tundish used for containing molten steel in metallurgical industry and discloses a ladle cover for a molten steel tundish, which comprises a left ladle cover, a middle ladle cover and a right ladle cover. All the three ladle covers are provided with baking holes; a pouring hole is arranged on the middle ladle cover; a temperature measuring hole is arranged on the left ladle cover or on the right ladle cover; upright reinforcing plates are installed in all the three ladle covers; aeration pipes are welded in all the three ladle covers; and casting material is poured to pre-bury the aeration pipes. With the ventile integral ladle cover for the sealed tundish, high temperature radiation at the site is greatly reduced and environment pollution caused by smoke and dust is remarkably reduced; the ladle cover prevents the reoxidation of the molten steel and improves the quality of the steel; and the service life of the ladle cover is prolonged.
Description
Technical field
The utility model relates to the tundish clad of splendid attire molten steel in a kind of metallurgy industry, clad in particularly a kind of vapor-permeable type integral sealing.
Background technology
Tundish is the intermediate receptacle between ladle and the crystallizer during the metallurgy industry continuous casting is produced, cover middle clad on tundish and be finish the needs of operations such as thermometric, sampling thereon for the ease of the operative employee and play a part heat insulation, prevent secondary oxidation of steel.Employed molten steel tundish clad in the prior art is divided into left and right two clads.Cover relief width and close between left and right two clads, middle part molten steel bare area is too big, approaches spacious lid casting, and the field worker that causes is born the serious phenomenon of secondary oxidation of steel that hyperthermia radiation is big, the operating environment flue dust fills the air and bring thus.In addition, material feeding is integrated poured to form, not to stay air-vent by watering in clad inside, can not realize the function of blowing.The inner no gusset of clad, non-deformability is poor, causes its service life short.
The utility model content
Technical problem to be solved in the utility model is that field worker that the middle Baogang water bare area of prior art causes too greatly bears that hyperthermia radiation is big, the operating environment flue dust fills the air, the problem of the easy secondary oxidation of molten steel, and existing clad non-deformability is poor, the problem that service life is short.
For solving the problems of the technologies described above, the utility model provides a kind of vapor-permeable type integral sealing molten steel tundish clad, and its technical characterictic is: described tundish clad comprises three clads in left, center, right, on three clads the baking hole is arranged all, also have plug hole on the middle clad, on a left side/right clad thermometer hole is arranged.
As improvement, perpendicular gusset is installed in the clad of described left, center, right, improve the non-deformability of clad.
Further, weld breather pipe respectively in the clad of described left, center, right, and pre-buried with watering the material feeding cast., molten steel and air are completely cut off open to the molten steel surface blown inert gas by this breather pipe, stop molten steel oxidation, improve steel.
Further again, described left, center, right clad end face is the arcuate arc plate, postpones steel plate deformed speed.
As preferred version, described baking hole, plug hole steel construction are knotting and water the material feeding cast.
Preferred again, the high-temperature fibre Seal Kit is installed between the clad of described left, center, right, effectively shorten stoving time, energy savings.
Use clad in the vapor-permeable type integral sealing of the present utility model, on-the-spot hyperthermia radiation reduces greatly, obviously reduces because of flue dust fills the air the environmental pollution that brings, and stops secondary oxidation of steel, has improved steel, has prolonged clad service life.
Description of drawings
Below in conjunction with the drawings and specific embodiments the technical solution of the utility model is further described in detail.
Fig. 1 is the vertical view of bag clad in the vapor-permeable type integral sealing of the present utility model.
Fig. 2 is the side sectional view of bag clad in the vapor-permeable type integral sealing of the present utility model.
The specific embodiment
As shown in Figure 1, middle bag clad is divided into 3 three of left clads 1, middle clad 2, right clad, and left clad 1, middle clad 2, right clad 3 all have baking hole 4, also has plug hole 5 on the middle clad 2, also has thermometer hole 6 on the right clad 3.The steel construction of baking hole 4, plug hole 5 is knotting and waters the material feeding cast, prevents hole inwall steel bonding water, and slag soaks warm steel construction and influences service life.In left clad 1, middle clad 2, right clad body, weld breather pipe, and pre-buried with watering the material feeding cast.When middle bag clad uses, left side clad 1, middle clad 2,3 amalgamations of right clad cover in the molten steel and wrap, left side clad 1, middle clad 2, right clad 3 adopt the alumina silicate fibre Seal Kit in twos each other, the alumina silicate fibre Seal Kit improves heat insulation, the sealing property of clad, make the programming rate that wraps in baking and the casting process fast, effectively shorten stoving time, energy savings, and improve the operating environment temperature, reduce the dust diffusion.Logical argon gas in the breather pipe makes molten steel surface form protective layer, moisture content in the air-isolation and oxygen, the consumption of covering agent in also reducing.
As shown in Figure 2, the cover plate end face of left clad 1, middle clad 2, right clad 3 all adopts steel plate processing arcuate arc plate 7, and the angle of calculating from mechanics, calorifics can postpone steel plate deformed speed.Perpendicular gusset 8 is installed, the non-deformability of raising clad between the inherent arcuate arc plate 7 of three clads and the base plate 10.The permanent layer fiberboard is installed on the base plate 10, is effectively stoped heat to be delivered on the steel construction, reduce the steel construction thermal deformation, improve operating environment.
It should be noted last that, the above specific embodiment is only unrestricted in order to the explanation the technical solution of the utility model, although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement the technical solution of the utility model, and not breaking away from the spirit and scope of technical solutions of the utility model, it all should be encompassed in the middle of the claim scope of the present utility model.
