Description
Technical field
The utility model relates to a kind of pouring in steel smelting protective cover, especially a kind of argon protecting cover of high speed steel mould 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 protecting cover of high speed steel mould pouring in steel smelting, comprises ring-type appendix, cone-shaped hood, air inlet pipe and connecting hose; Ring-type appendix is provided with a ring annular groove along its lower tube wall; Air inlet pipe is connected with ring-type appendix, and connecting hose is connected with air inlet pipe; Air inlet pipe is provided with air intake control valve door; 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 be provided with a circle 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 protecting cover to use to other casting molds; Adopt, on ring-type appendix, one ring annular groove is set along its lower tube wall, play stabilization when argon protecting cover is placed on casting mold, prevent relative sliding impact and use; Connecting hose is adopted to facilitate argon protecting cover to dock with argon gas source, and by air intake control valve gate control break-make.
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 protecting cover to use to other casting molds; (6) adopt, on ring-type appendix, one ring annular groove is set along its lower tube wall, play stabilization when argon protecting cover is placed on casting mold, prevent relative sliding impact and use; (7) connecting hose is adopted to facilitate argon protecting cover to dock with argon gas source, and by air intake control valve gate control break-make.

Detailed description of the invention
As shown in Figure 1, the argon protecting cover of high speed steel mould pouring in steel smelting of the present utility model comprises: comprise ring-type appendix 2, cone-shaped hood 3, air inlet pipe 4 and connecting hose 11.Wherein, ring-type appendix 2 is provided with a ring annular groove 9 along its lower tube wall; Air inlet pipe 4 is connected with ring-type appendix 2, and connecting hose 11 is connected with air inlet pipe 4; Air inlet pipe 4 is provided with air intake control valve door 10; Cone-shaped hood 3 cover cap above ring-type appendix 2, and is provided with the opening with sprue gate equal diameters at the top of cone-shaped hood 3; The inner ring of ring-type appendix 2 is at least provided with three argon gas escape pipes 5, and 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 a circle 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 protecting cover in use, is first moved to above casting mold 1 by handle 8 by the argon protecting cover of high speed steel mould pouring in steel smelting of the present utility model, and makes annular groove 9 be buckled on the edge of steel mold mouth; Again air inlet pipe 4 is connected with argon gas source by connecting hose 11, when carrying out pouring molten steel, open air intake control valve door 10 and pass into argon gas, argon gas sprays from eight argon gas escape pipes 5 after ring-type appendix 2, 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 flow-stopping plate 6, extends the service time of argon gas in casting moulds concrete 1 further.
