Description

A kind of argon protective device of pouring in steel smelting
Technical field
The utility model relates to a kind of pouring in steel smelting protective device, especially a kind of argon protective device of pouring in steel smelting.
Background technology
When carrying out pouring in steel smelting, because the molten steel of cast directly contacts with air ground, the secondary oxidation of steel of cast can be caused, thus cause the Quality Down of steel-making.
Summary of the invention
The technical problems to be solved in the utility model be molten steel and the air of cast directly contact the problem of the secondary oxidation of steel causing cast.
In order to solve the problems of the technologies described above, the utility model provides the argon protective device of pouring in steel smelting, comprises ring-type appendix, cone-shaped hood and air inlet pipe; Ring-type appendix is provided with a circle along its lower tube wall protruding; Air inlet pipe communicates with ring-type appendix; Cone-shaped hood cover cap is above ring-type appendix, and the top of cone-shaped hood is provided with the opening with sprue gate equal diameters; The inner ring of ring-type appendix is at least provided with three argon gas escape pipes, argon gas escape pipe communicates with ring-type appendix; Argon gas escape pipe be tilted to down and point to casting moulds specifically in; The female cone wall of cone-shaped hood is at least provided with one piece be tilted under flow-stopping plate, the downward-sloping angle of flow-stopping plate is 30 ° ~ 40 °; The outer cone wall of cone-shaped hood is arranged with a pair handle.
Adopt and argon gas escape pipe is set on the inner ring of ring-type appendix, the molten steel in sprue gate is separated due to argon gas and air, effectively prevent the molten steel generation secondary oxidation in sprue gate; Argon gas escape pipe is tilted to down and point to casting moulds concrete in can by argon gas along with pour steel flow into together casting moulds specifically in, prevent pour steel generation secondary oxidation further; Adopt cone-shaped hood can extend the service time of argon gas in casting moulds is concrete, the utilization rate of raising argon gas; Adopt flow-stopping plate the argon gas of rising can be pressed to casting moulds specifically in, extend the service time of argon gas in casting moulds is concrete further; A pair handle is adopted to facilitate mobile argon protective device to use to other casting molds; Adopt, on ring-type appendix, one circle projection is set along its lower tube wall, play stabilization when argon protective device is placed on casting mold, prevent relative sliding impact and use.
As further restriction scheme of the present utility model, the first-class radian of inner ring of ring-type appendix is provided with eight argon gas escape pipes.
The beneficial effects of the utility model are: (1) adopts on the inner ring of ring-type appendix, arranges argon gas escape pipe, the molten steel in sprue gate is separated due to argon gas and air, effectively prevent the molten steel generation secondary oxidation in sprue gate; (2) argon gas escape pipe is tilted to down and point to casting moulds concrete in can by argon gas along with pour steel flow into together casting moulds specifically in, prevent pour steel generation secondary oxidation further; (3) cone-shaped hood is adopted can to extend the service time of argon gas in casting moulds is concrete, the utilization rate of raising argon gas; (4) adopt flow-stopping plate the argon gas of rising can be pressed to casting moulds specifically in, extend the service time of argon gas in casting moulds is concrete further; (5) a pair handle is adopted to facilitate mobile argon protective device to use to other casting molds; (6) adopt, on ring-type appendix, one circle projection is set along its lower tube wall, play stabilization when argon protective device is placed on casting mold, prevent relative sliding impact and use.

Detailed description of the invention
As shown in Figure 1, the argon protective device of pouring in steel smelting of the present utility model comprises: ring-type appendix 2, cone-shaped hood 3 and air inlet pipe 4.Wherein, ring-type appendix 2 is provided with a circle projection 9 along its lower tube wall, and it is corresponding that depression 7 is enclosed at this projection 9 and one of casting mold 1 sprue gate place, effectively can improve stability when argon protective device uses; Air inlet pipe 4 communicates with ring-type appendix 2; Cone-shaped hood 3 cover cap is above ring-type appendix 2, and the top of cone-shaped hood 3 is provided with the opening with sprue gate equal diameters; Be provided with eight argon gas escape pipes 5 at the first-class radian of the inner ring of ring-type appendix 2, argon gas escape pipe 5 communicates with ring-type appendix 2; Argon gas escape pipe 5 is tilted to down and points in casting moulds concrete 1; The female cone wall of cone-shaped hood 3 is provided with six pieces be tilted under flow-stopping plate 6, the downward-sloping angle of flow-stopping plate 6 is 30 ° ~ 40 °; The outer cone wall of cone-shaped hood 3 is arranged with a pair handle 8.
Argon protective device in use, is first moved to above casting mold 1 by handle 8 by the argon protective device of pouring in steel smelting of the present utility model, and makes protruding 9 to be embedded in depression 7; Again air inlet pipe 4 is connected with argon gas source, when carrying out pouring molten steel, open the switch of argon gas source, pass into argon gas, argon gas sprays from eight argon gas escape pipes 5 after ring-type appendix 2, and the molecular weight due to argon gas is greater than the mean molecule quantity of air, so argon gas will sink and covers above the molten steel in sprue gate, separated the contact of molten steel and air, thus there is secondary oxidation phenomenon in the molten steel that effectively prevent cast; Simultaneously when pouring molten steel, argon gas flows down together along with molten steel, further increases oxidation proof properties; The argon gas of rising can be gathered in casting moulds concrete 1 by cone-shaped hood 3, extends the time of staying of argon gas, and simultaneously the argon gas of rising presses in casting moulds concrete 1 by six flow-stopping plates 6, extends the service time of argon gas in casting moulds concrete 1 further.
