The anti-seepage smelting steel ladle disclosed by the invention has the advantages that the air hole of the air brick on the steel ladle is not blocked by molten steel, the service life of the steel ladle is long, and the enterprise production and usage cost is low.
Description
Technical field
The present invention relates to the antiseepage stifled smelting ladle of steel-making.
Background technology
Ladle is one of visual plant of steel-making, and the production and application cost of length on enterprise in its work-ing life has direct impact.The structure of the ladle used at present is: comprise box hat, the bottom of box hat is provided with gas permeable brick, and what be provided with to protect gas permeable brick in box hat protects brick, and gas permeable brick is connected with the intake ducting with bottom blowpipe hydraulic quick coupler.During work, the bottom blowing pipeline of the bottom blowpipe hydraulic quick coupler on intake ducting and argon gas gas-holder is connected, the indifferent gas cognition such as the argon gas in such argon gas gas-holder are blown into ladle by the breather hole of gas permeable brick, thus molten steel in ladle is fully stirred, the various materials being added on molten steel can be melted quickly and evenly, the object remove detrimental impurity to reach, improving Cleanliness of Molten Steel.The shortcoming of the ladle used at present is: when ladle does not need to be blown into argon gas again and directly extracts bottom blowing pipeline fast, negative pressure can be produced in the breather hole of gas permeable brick, molten steel under the effect of negative pressure in ladle is easily inhaled in the breather hole of gas permeable brick, be inhaled into the easy condensation of molten steel in breather hole and block breather hole, have a strong impact on bottom blowing effect, cause ladle easily because the breather hole of gas permeable brick is blocked and scraps, thus substantially reduce the work-ing life of ladle.
Summary of the invention
The object of this invention is to provide a kind of antiseepage stifled smelting ladle of long service life.
For achieving the above object, present invention employs following technical scheme: described antiseepage is stifled smelts ladle, comprise: bottom is provided with the box hat of gas permeable brick, box hat is provided with gas storage bag, gas permeable brick is connected by the outlet of the first connecting tube with gas storage bag, the import of gas storage bag is connected with bottom blowpipe hydraulic quick coupler by the second connecting tube, and the second connecting tube is provided with unidirectional stop valve, and described unidirectional stop valve only allows gas to enter gas storage bag along the second connecting tube.
Further, aforesaid antiseepage is stifled smelts ladle, wherein: the ratio range between the volume of described gas storage bag and the volume of box hat is 0.00007-0.00009.
Further, aforesaid antiseepage is stifled smelts ladle, wherein: the ratio between the volume of described gas storage bag and the volume of box hat is 0.00008.
Further, aforesaid antiseepage is stifled smelts ladle, wherein: the import of described gas storage bag is lower than the outlet of gas storage bag.
Further, aforesaid antiseepage is stifled smelts ladle, wherein: be arranged with a circle ladle guard circle in the bottom of box hat, gas storage bag is arranged on the box hat in ladle guard circle.
By the enforcement of technique scheme, advantage of the present invention is: can guarantee that molten steel in ladle can not enter the breather hole of gas permeable brick by reverse osmosis, make the gas permeable brick of ladle in use can not be blocked, not only extend the long service life of ladle, and reduce the production and application cost of enterprise.
Accompanying drawing explanation
Fig. 1 is that the structural principle schematic diagram smelting ladle is blocked up in antiseepage of the present invention.
Embodiment
Below in conjunction with the drawings and specific embodiments, the invention will be further described.
As shown in Figure 1, described antiseepage is stifled smelts ladle, comprise: bottom is provided with the box hat 2 of gas permeable brick 1, box hat 2 is provided with gas storage bag 3, gas permeable brick 1 is connected with the outlet of gas storage bag 3 by the first connecting tube 4, the import of gas storage bag 3 is connected with bottom blowpipe hydraulic quick coupler 6 by the second connecting tube 5, second connecting tube 5 is provided with unidirectional stop valve 7, described unidirectional stop valve 7 allows gas to enter gas storage bag 3 along the second connecting tube 5, ratio range between the volume of described gas storage bag 3 and the volume of box hat 2 is 0.00007-0.00009, in the present embodiment, ratio between the volume of described gas storage bag 3 and the volume of box hat 2 is 0.00008, the gas storage bag 3 of this volume size can avoid the molten steel in box hat to infiltrate the breather hole of gas permeable brick 1 better, can reduce to maximum amplitude again the production and application cost of enterprise, in the present embodiment, the import of described gas storage bag 3 is lower than the outlet of gas storage bag 3, the gas entering gas storage bag 3 so first can rise to the outlet of gas storage bag 3, the first connecting tube 4 be connected with the breather hole of gas permeable brick 1 is entered again from the outlet of gas storage bag 3, in the process that the gases such as argon gas rise in gas storage bag 3, impurity in gas can be deposited on bottom gas storage bag 3 downwards gradually, thus guarantee that the gases such as pure argon gas enter ladle through the breather hole of gas permeable brick 1, the impurity that effectively prevent in the gases such as argon gas enters molten steel and pollutes molten steel, substantially increase the purity of molten steel, in the present embodiment, a circle ladle guard circle 8 is arranged with in the bottom of box hat 2, gas storage bag 3 is arranged on the box hat 2 in ladle guard circle 8, gas storage bag 3 effectively can be avoided like this to damage because of collision in processes such as carryings, extend the work-ing life of ladle further,
Principle of work of the present invention is as follows:
When need to molten steel blowing argon gas in ladle time, bottom blowpipe hydraulic quick coupler 6 and the bottom blowing pipeline 10 on argon gas gas-holder 9 are connected, now, argon gas in argon gas gas-holder 9 first can enter gas storage bag 3 along the second connecting tube 5, the argon gas entering gas storage bag 3 rises to the outlet of gas storage bag 3 again, in the process that argon gas rises in gas storage bag 3, impurity in argon gas can be deposited on bottom gas storage bag 3 downwards gradually, clean argon gas then enters the first connecting tube 4 from the outlet of gas storage bag 3, the molten steel box hat 2 is entered again from the breather hole of gas permeable brick 1, the impurity that effectively prevent in argon gas enters molten steel and pollutes molten steel, improve the purity of molten steel, be blown in the process of molten steel in box hat 2 at argon gas by the breather hole of gas permeable brick 1, full argon gas can be stored up in gas storage bag 3, store in the gas storage bag 3 of argon gas and can there is gaseous tension, when not needing to molten steel blowing argon gas in box hat 2, directly extract the bottom blowing pipeline 10 on argon gas gas-holder 9, now, because argon gas is locked in gas storage bag 3 by unidirectional stop valve 7, effectively prevent from producing negative pressure because of gas loss in gas storage bag 3, and under the gaseous tension effect of the argon gas stored in gas storage bag 3, make molten steel enter in the breather hole of gas permeable brick 1 by reverse osmosis further, even if extracting the moment of bottom blowing pipeline 10, gas storage bag 3 is a part of argon gas that runs off because of bottom blowpipe hydraulic quick coupler place generation negative pressure, but the gaseous tension remaining argon gas in gas storage bag 3 is also enough to guarantee that molten steel can not enter in the breather hole of gas permeable brick 1 by reverse osmosis, and then the breather hole of gas permeable brick can not be blocked by molten steel, thus extend the work-ing life of ladle, also greatly reduce the production and application cost of enterprise.
