Abstract
The utility model discloses a side is wrapped long mouth of a river argon greatly and is sealed structure, including mouth of a river body, body vertical cross -section in the mouth of a river is " T " shape, and its central vertical shaping has a potting channel, the top surface shaping of mouth of a river body has a plurality of ring array's arch, mouth of a river body upper portion shaping has the argon gas passageway, the argon gas passageway lets in mouth of a river body from the lateral part of mouth of a river body, it has the argon gas outer vent to open in the arch, the argon gas passageway is linked together with the argon gas outer vent, potting channel's surperficial shaping has annular channel, and annular channel exports in opening and having the argon gas, the argon gas passageway is linked together with annular channel, the protection device of this structure, the protective range of protection gas such as messenger's argon gas expands to the import department at the mouth of a river, makes this molten iron of locating also can receive the protection, can not leave the white space, reduces the change of molten iron, improves the ultimate quality of product.
Description
Technical field
This utility model relates to the mouth of a river of a kind of pouring molten iron, specifically a kind of side big bag long nozzle argon seal structure.
Background technology
In pouring technology commonly used to sprue gate; owing to being that molten iron passes through in sprue gate; molten iron at high temperature easily aoxidizes; so generally arranging inert gas shielding at mouth of a river place; mostly existing protection structure is the inside at runner; the molten iron having just enter into runner is not protected, or easily aoxidizes.
Utility model content
For deficiency of the prior art, it is necessary to a kind of protection domain is bigger, the molten iron having just enter into runner is made to be also affected by the structure of protection.
For realizing above-mentioned technical scheme, this utility model needs a kind of side big bag long nozzle argon seal structure, including mouth of a river body, mouth of a river body vertical cross-section is " T " shape, its center vertically forms cast passage, the end face of described mouth of a river body forms the projection of multiple annular array, described mouth of a river body upper part forms ar gas passage, described ar gas passage passes into mouth of a river body from the sidepiece of mouth of a river body, described projection has argon outer vent, described ar gas passage is connected with argon outer vent, the surface forming of described cast passage has circular passage, circular passage has argon inner outlet, described ar gas passage is connected with circular passage.
The quantity of described projection is 6 or 8, and annular array is at the upper surface of mouth of a river body.
Body side, the described mouth of a river forms multiple air inlet, and described air inlet annular array is on the body of the mouth of a river.
Described cast passage is divided into two parts, and including cast taper seat and sprue, described cast taper seat is up big and down small taper, and described sprue is up-small and down-big taper.
Described mouth of a river body exterior forms sinterskin.
The utility model has the advantages that: the protection device of this structure, make the protection domain of the protection gas such as argon expand to the import department at the mouth of a river, make the molten iron at this place also can be protected, will not leave behind white space, reduce the change of molten iron, improve the quality that product is final；Argon inner outlet out forms argon curtain wall also by projection is ventilative from inside, better isolation air and molten steel.
Accompanying drawing explanation
Fig. 1 is the structural representation of side big bag long nozzle argon seal structure；
Fig. 2 is the top view of side big bag long nozzle argon seal structure；
In figure: 1, mouth of a river body, 2, protruding, 3, ar gas passage, 4, argon outer vent, 5, circular passage, 6, air inlet, 7, cast taper seat, 8, sprue.
Detailed description of the invention
According to Fig. 1, specific embodiment of the utility model is described, including mouth of a river body 1, mouth of a river body 1 vertical cross-section is " T " shape, its center vertically forms cast passage, the end face of described mouth of a river body 1 forms the projection 2 of multiple annular array, described mouth of a river body upper part forms ar gas passage 3, described ar gas passage 3 passes into mouth of a river body 1 from the sidepiece of mouth of a river body 1, argon outer vent 4 is had on described protruding 2, described ar gas passage 3 is connected with argon outer vent 4, the surface forming of described cast passage has circular passage 5, circular passage 5 has argon inner outlet, described ar gas passage 3 is connected with circular passage 5.
The described quantity of protruding 2 is 6 or 8, and annular array is at the upper surface of mouth of a river body 1.
Body 1 side, the described mouth of a river forms multiple air inlet 6, and described air inlet 6 annular array is on mouth of a river body 1.
Described cast passage is divided into two parts, and including cast taper seat 7 and sprue 8, described cast taper seat 7 is up big and down small taper, and described sprue 8 is up-small and down-big taper.
Described mouth of a river body 1 is outside forms sinterskin.
The inside of this device arranges protective gas passage, and protective gas flows wherein and leads to the forefront of cast, make molten iron effectively completely cut off with in air.
