Abstract
The utility model relates to a gas protective device for smelting pool of a continuous casting machine. The utility model is characterized in that an elastic telescopic sleeve (2) presses on the upper end of a lining sleeve (5) which is provided with a sleeve pipe (1) and a sealing plate (4), A sealing lip plate (3) is fixed on the end surface of a frame (8), the upper end of a smelting pool is provided with a gas protective device, the sides of two water cooled rolls are provided with cloth air pipes, and the space in the molten pool is filled with inert gas for preventing the molten steel in the molten pool from having the reoxidation of air. Because the integral device is sealed, the consumption of the inert gas is little, sealing effect is good, the surface reoxidation of the molten steel in the molten pool can be effectively prevented, and the quality of the strip steel blank is enhanced.
Description
The utility model belongs to field of metal casting technology, particularly a kind of gas shield device that is used for the continuous casting molten bath.
In metallurgical industry is produced, often adopt continuous casting process that the iron and steel blank is shaped.Molten steel is entering the molten bath through tundish in the continuous casting, requires molten steel to be in semisolid and not oxidized in the molten bath of two roll shop buildings.Because weld pool surface is directly exposed in the air, easily makes secondary oxidation of steel, influence band billet quality.
The purpose of this utility model provides a kind of conticaster molten bath gas shield device.It can protect the molten bath, and the secondary oxidation of molten steel does not take place, and guarantees the characteristics of the quality of band steel billet.
For reaching above-mentioned purpose, of the present utility model it is characterized in that is pressed in the lining upper end that has sleeve pipe and sealing plate with the elastic telescopic cover, and the sealing labial lamina is fixed on the end face of shelf.
Sealing plate of the present utility model is provided with the gentle shrouding of gas distribution pipe.Wherein gas distribution pipe is provided with a plurality of holes.The sealing gland plate can be labyrinth shape.
Sealing plate of the present utility model is arranged on the lower end of lining.Lining is made with refractory material.
The utility model is installed gas shield device in molten bath upper end, two water cooled rolls sides are provided with gas distribution pipe, and can make the space in the molten bath is inert gas, with the molten steel in the protection molten bath not by the air secondary oxidation.Because whole device is sealing, so the inert gas consumption is few, good sealing effect can prevent molten bath molten steel surface secondary oxidation effectively, improves the band billet quality.
Below by embodiment the utility model is described further.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the enlarged diagram of sealing plate.
1 is sleeve pipe among the figure, and 2 is the elastic telescopic cover, and 3 are the sealing labial lamina, and 4 is sealing plate, and 5 is lining, and 6 is gas distribution pipe, and 7 is the sealing gland plate, and 8 is shelf.
Elastic telescopic cover 2 is pressed in the lining 5 that has sleeve pipe and the upper end of sealing plate 4, forming the sealing gas hood, is provided with sealing labial lamina 3 at the end face of shelf 8, sealing labial lamina 3 has a gap with the water cooled rolls end face.When water cooled rolls rotated, under the drive of air-flow, sealing labial lamina 3 was close to water cooled rolls, brought cold air into to prevent body of roll rotation; Be provided with gas distribution pipe 6 gentle shroudings 7 in the sealing plate 4, inert gas by gas distribution pipe 6 through two air flues, one enters the weld pool surface space through labyrinth shape sealing gland plate 7 downwards, in the molten bath, form the inert gas space, one upwards purges roll surface, shelves are lived roll surface and are brought cold air into, to guarantee the inert gas atmosphere in the molten bath.
Sealing gland plate 7 is a labyrinth shape, and the inert gas that enters in the molten bath is not taken out of with the surfaces of revolution of water cooled rolls.
Be 7 distortion of the sealing plate in the anti-locking apparatus, lining 5 adopts refractory material.
