Abstract
The utility model relates to a hermetic-sealing ladle sleeve tube for continuous casting, which belongs to the technical field of iron and steel smelting equipment. The utility model aims at providing a hermetic-sealing ladle sleeve tube for continuous casting which can seal and protect steel ladle to middle ladle preferably, and reduce reoxidation and steel inclusions. The utility model has the technical scheme that the hermetic-sealing ladle sleeve tube for continuous casting is composed of an air chamber and a sleeve tube; the air chamber is a circular ring-shaped hollow cavity body; the sleeve tube is a long tube, wherein both ends of which are openings; the bottom of the air chamber and one end of the sleeve tube are connected into one body; the upper part of the air chamber along the circumference of a chamber wall is evenly distributed with a plurality of argon gas blowing holes. By make use of the hermetic-sealing ladle sleeve tube for continuous casting, argon gas is blown into the air chamber by argon gas blowing mouths, and is evenly distributed to a plurality of argon gas blowing holes by the air chamber, so the utility model avoids the phenomena that the argon gas blowing of the original ladle sleeve tube is uneven and part of molten steel can not obtain effective protection. The utility model greatly avoids the reoxidation of the molten steel in a casting working procedure and the increasing of non-metallic inclusion content.
Description
Technical field
The utility model relates to and a kind of ladle to the molten steel of tundish is carried out the device of blowing argon, belongs to the steelmaking equipment technical field.
Background technology
In modern STEELMAKING PRODUCTION, molten steel after refining is the normal safeguard measure that makes molten steel and air insulated that adopts in the process from the ladle to the tundish.Otherwise, can make qualified molten steel produce secondary oxidation, cause the non-metallic inclusion in the qualified molten steel to increase, its recruitment can reach 70% of field trash total amount in the molten steel.In casting process, if these field trashes can not be removed, not only easily cause sprue gate to stop up, jeopardize the cast production process, but also can cause continuous casting billet quality to descend, even unqualified; Enter covering slag if in casting process, be mingled with in a large number, the covering slag performance is changed, make strand produce blemish.Particularly, from the technology setting, the content that is mingled with in the molten steel is reduced to low scope in the refining process, if make molten steel produce secondary oxidation again in the cast link of postorder, cause being mingled with content and raise, all that has been achieved is spoiled to make refining effect undoubtedly.
In the existing continuous casting seal protection pouring technology, the argon gas of big canning tube overflows in a large number at inflatable mouth easily, makes the molten steel away from the inflatable mouth position can not get argon shield, has influenced the protection effect.In view of this, should develop the big canning tube of a kind of novel sealing, improve the continuous casting sealing effectiveness.
Summary of the invention
Technical problem to be solved in the utility model provides a kind ofly can be better carries out seal protection to ladle to the molten steel of tundish, reduces secondary oxidation, and the continuous casting that reduces the field trash in the steel seals big canning tube.
The technical scheme that addresses the above problem is:
A kind of continuous casting seals big canning tube, and it is made up of air chamber, sleeve pipe, and air chamber is the ring-type hollow cavity, and sleeve pipe is the both ends open long tube, and air chamber bottom connects as one with sleeve pipe one end, on air chamber top along a plurality of Argon pores of locular wall circumference uniform distribution.
Above-mentioned continuous casting seals big canning tube, and described air chamber cavity diameter is greater than the bore of sleeve pipe, and the air chamber bottom is up big and down small taper, and the tube wall of sleeve pipe is connected with the air chamber tapering.
Above-mentioned continuous casting seals big canning tube, and described Argon pore is 4-12.
Above-mentioned continuous casting seals big canning tube, and described air chamber cavity inner wall is step-like, and cavity top internal diameter is greater than the bottom.
Above-mentioned continuous casting seals big canning tube, and described casing inner diameter upper end is greater than the lower end, and the tapering of tube chamber is 20 °-60 °.
Adopt the continuous casting of this structure to seal big canning tube; argon gas is chewed by Argon and is blown into air chamber; give a plurality of Argon pores by the air chamber uniform distribution again along the locular wall circumference uniform distribution; therefore avoided former big canning tube Argon inequality; the phenomenon that the part molten steel is not effectively protected has been avoided the secondary oxidation of molten steel in the cast operation, the generation that nonmetal inclusion content rises situation largely.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the A-A cutaway view of Fig. 1.
Mark is as follows among the figure: air chamber 1, sleeve pipe 2, air chamber cavity 3, Argon pore 4, air chamber tapering 5
The specific embodiment
Referring to accompanying drawing, the utility model continuous casting seals big canning tube the ventilative ring of the high alumina matter of former sleeve pipe is removed, and changes the air chamber with the aluminium carbon material of sleeve pipe one into.The cavity diameter of air chamber 1 is greater than the bore of sleeve pipe 2, and air chamber 1 bottom is up big and down small taper, and the tube wall of sleeve pipe 2 and air chamber tapering 5 connect as one.At air chamber 1 circumference 8 Argon pores 4 are arranged, argon gas is chewed by Argon and is blown into air chamber 1, gives 8 Argon pores 4 by air chamber 1 uniform distribution again.
Referring to accompanying drawing, the air chamber cavity inner wall is step-like, and cavity top internal diameter is greater than the bottom, and the air chamber cavity upper diameter of an embodiment is 120mm, and lower diameter is 110mm.
Still referring to accompanying drawing, the casing inner diameter upper end is greater than the lower end, and tube chamber is certain taper, and the sleeve pipe upper-end inner diameter of an embodiment is 55mm, and bottom diameter is 45mm, and the sleeve pipe upper end is connected with air chamber.
During use; by the operative employee this continuous casting is sealed big canning tube at the continuous casting scene and is contained on the manipulator, unwrap greatly water the back be enclosed within on the big water-coating port by the operative employee, connect argon gas simultaneously; open the molten steel ambient air is isolated; play protection cast effect, Argon new casing gas field, 8 hole is more even, and the molten steel protection is respond well; improved the molten steel degree of purity; improve steel product quality, avoided former big canning tube Argon inequality, the phenomenon that the part molten steel is not effectively protected.
