Description
Technical field
The present invention relates to a kind of pouring in steel smelting protection device, the argon protective device of especially a kind of 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.
Content 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 protective device of pouring in steel smelting, including ring-type appendix, cone-shaped hood and air inlet pipe；It is provided with a circle along its lower tube wall protruding on ring-type appendix；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；At least provided with three argon gas escape pipes on the inner ring of ring-type appendix, argon gas escape pipe communicates with ring-type appendix；Argon gas escape pipe diagonally downward and points in casting mold body；At least provided with one piece of flow-stopping plate diagonally downward on the female cone wall of cone-shaped hood, 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 gas 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 gas, effectively prevent the molten steel generation secondary oxidation in sprue gate；Argon gas escape pipe diagonally downward and can be prevented pour steel generation secondary oxidation by argon gas as pour steel flows in casting mold body together in pointing to casting mold body further；Use cone-shaped hood can extend the use time in casting mold body for the argon gas, improve the utilization rate of argon gas；Use flow-stopping plate can press in casting mold body by the argon gas of rising, extend the use time in casting mold body for the argon gas further；Use a pair handle to be moved easily argon protective device to use to other casting molds；Use, 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 impact of relatively sliding and use.
As the restriction scheme further of the present invention, the first-class radian of inner ring of ring-type appendix is provided with eight argon gas escape pipes.
The beneficial effects of the present invention is: (1) uses and arranges argon gas escape pipe on the inner ring of ring-type appendix, make the molten steel in sprue gate separate with air due to argon gas, effectively prevent the molten steel generation secondary oxidation in sprue gate；(2) argon gas escape pipe diagonally downward and can be prevented pour steel generation secondary oxidation by argon gas as pour steel flows in casting mold body together in pointing to casting mold body further；(3) use cone-shaped hood can extend the use time in casting mold body for the argon gas, improve the utilization rate of argon gas；(4) use flow-stopping plate can press in casting mold body by the argon gas of rising, extend the use time in casting mold body for the argon gas further；(5) use a pair handle to be moved easily argon protective device to use to other casting molds；(6) use, 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 impact of relatively sliding and use.
Brief description
Fig. 1 is the side-looking structural representation of the present invention；
Fig. 2 is the plan structure schematic diagram of the present invention；
Fig. 3 is sectional view at A-A in Fig. 1.
Detailed description of the invention
As it is shown in figure 1, the argon protective device of the pouring in steel smelting of the present invention includes: ring-type appendix the 2nd, cone-shaped hood 3 and air inlet pipe 4.Wherein, being provided with a circle projection 9 along its lower tube wall on ring-type appendix 2, this projection 9 is corresponding with the circle depression 7 at casting mold 1 sprue gate, can effectively 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；The first-class radian of inner ring at ring-type appendix 2 is provided with eight argon gas escape pipes 5, and argon gas escape pipe 5 communicates with ring-type appendix 2；Argon gas escape pipe 5 diagonally downward and points in casting moulds concrete 1；Being provided with six pieces of flow-stopping plates 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 protective device of the pouring in steel smelting of the present invention in use, first passes through handle 8 and moves to argon protective device above casting mold 1, 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, it is passed through argon gas, argon gas sprays after ring-type appendix 2 at eight argon gas escape pipes 5, owing to the molecular weight of argon gas is more than the mean molecule quantity of air, so argon gas will sink and cover in sprue gate molten steel above, 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 gas flows down together with molten steel, further increases oxidation proof properties；Cone-shaped hood 3 can be gathered in the argon gas of rising in casting moulds concrete 1, extends the time of staying of argon gas, and the argon gas of rising is pressed in casting moulds concrete 1 by six flow-stopping plates 6 simultaneously, extends the use time in casting moulds concrete 1 for the argon gas further.
