Description
Technical field
The present invention relates to a kind of pouring in steel smelting protective cover, the argon protecting cover of a kind of high speed steel mould pouring in steel smelting.
Background technology
When carrying out pouring in steel smelting, owing to 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 problem to be solved in the present invention is the problem that the molten steel poured into a mould directly contacts, with air ground, the secondary oxidation of steel causing cast.
In order to solve above-mentioned technical problem, the invention provides the argon protecting cover of high speed steel mould pouring in steel smelting, including ring-type appendix, cone-shaped hood, air inlet pipe and connection flexible pipe；It is provided with a ring annular groove along its lower tube wall on ring-type appendix；Air inlet pipe is connected with ring-type appendix, connects flexible pipe and 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 and the opening of sprue gate equal diameters；At least provided with three argon escape pipes on the inner ring of ring-type appendix, argon escape pipe communicates with ring-type appendix；Argon escape pipe diagonally downward and points in casting mold body；The female cone wall of cone-shaped hood is provided with circle flow-stopping plate diagonally downward, and the downward-sloping angle of flow-stopping plate is 30 ° ~ 40 °；It is arranged with a pair handle on the outer cone wall of cone-shaped hood.
Use and argon escape pipe is set on the inner ring of ring-type appendix, make the molten steel in sprue gate separate with air due to argon, effectively prevent the molten steel generation secondary oxidation in sprue gate；Argon escape pipe diagonally downward and can be prevented pour steel generation secondary oxidation by argon along with pour steel flows in casting mold body together in pointing to casting mold body further；Use cone-shaped hood can extend the argon use time in casting mold body, improve the utilization rate of argon；Use flow-stopping plate can press in casting mold body by the argon of rising, extend the argon use time in casting mold body further；Use a pair handle to be moved easily argon protecting cover to use to other casting molds；Use, 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 impact of relatively sliding and use；Connection flexible pipe is used to facilitate argon protecting cover to dock with argon gas source, and by air intake control valve gate control break-make.
As the scheme that limits further of the present invention, the first-class radian of inner ring of ring-type appendix is provided with eight argon escape pipes.
The beneficial effects of the present invention is: (1) uses and arranges argon escape pipe on the inner ring of ring-type appendix, makes the molten steel in sprue gate separate with air due to argon, effectively prevent the molten steel generation secondary oxidation in sprue gate；(2) argon escape pipe diagonally downward and can be prevented pour steel generation secondary oxidation by argon along with pour steel flows in casting mold body together in pointing to casting mold body further；(3) use cone-shaped hood can extend the argon use time in casting mold body, improve the utilization rate of argon；(4) use flow-stopping plate can press in casting mold body by the argon of rising, extend the argon use time in casting mold body further；(5) use a pair handle to be moved easily argon protecting cover to use to other casting molds；(6) use, 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 impact of relatively sliding and use；(7) connection flexible pipe is used 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 it is shown in figure 1, the argon protecting cover of the high speed steel mould pouring in steel smelting of the present invention includes: include ring-type appendix 2, cone-shaped hood 3, air inlet pipe 4 and connect flexible pipe 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, connects flexible pipe 11 and 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 is above ring-type appendix 2, and is provided with and the opening of sprue gate equal diameters at the top of cone-shaped hood 3；At least provided with three argon escape pipes 5 on the inner ring of ring-type appendix 2, argon escape pipe 5 communicates with ring-type appendix 2；Argon escape pipe 5 diagonally downward and points in casting moulds concrete 1；Being provided with circle flow-stopping plate 6 diagonally downward on the female cone wall of cone-shaped hood 3, 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.
The argon protecting cover of the high speed steel mould pouring in steel smelting of the present invention in use, first passes through handle 8 and is moved to above casting mold 1 by argon protecting cover, 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 flexible pipe 11, when carrying out pouring molten steel, open air intake control valve door 10 and be passed through argon, argon sprays after ring-type appendix 2 at eight argon escape pipes 5, molecular weight due to argon is more than the mean molecule quantity of air, so argon will sink and cover above the molten steel in sprue gate, separate contacting of molten steel and air, thus secondary oxidation phenomenon has occurred in the molten steel that effectively prevent cast；Simultaneously when pouring molten steel, argon flows down together along with molten steel, further increases oxidation proof properties；The argon of rising can be gathered in casting moulds concrete 1 by cone-shaped hood 3, extends the time of staying of argon, and the argon of rising is pressed in casting moulds concrete 1 by flow-stopping plate 6 simultaneously, extends the argon use time in casting moulds concrete 1 further.
