Abstract

The utility model discloses a ladle anti-seepage argon blowing system, which comprises an air source communicated with an argon gas inlet of a ladle gas permeable brick, and also includes a gas buffer tank and a one-way air inlet valve, the air source is communicated with the argon gas inlet of the ladle gas permeable brick through the gas buffer tank and the one-way air inlet valve sequentially, the gas buffer tank and the one-way valve are arranged on the ladle argon gas inlet pipeline, when closing the air source to stop argon blowing, the rear pipe section of a pipeline valve has positive pressure to close the one-way valve, so as to prevent liquid steel from entering slits of the gas permeable brick due to negative pressure; and when the pipeline pressure fluctuates, due to the buffering function of the buffer tank, the rear pipeline pressure of the buffer tank will not fluctuate along with the system, so as to eliminate relative negative pressure status due to pressure fluctuation of the system, maximally prevent the liquid steel from seeping into the slits of the gas permeable brick, and protect the gas permeable brick from being eroded due to liquid seepage, thereby avoiding steel bleed-out accidents of ladles, and ensuring safe production.

Description

Ladle antiseepage argon blowing system

Technical field

The utility model relates to a kind of ladle utility appliance, particularly a kind of ladle antiseepage argon blowing system.

Background technology

Ladle is the elevated temperature vessel that is used for the splendid attire high-temperature molten steel and necessarily reacts; The ladle argon-blown device mainly is to be used for steel refining technology; The structure of BOTTOM ARGON BLOWING ladle is at ladle bottom gas permeable brick to be set, and argon gas enters ladle inside by the ventilative core that pipeline enters gas permeable brick, and molten steel is stirred.

In the prior art, when carrying out Argon, pressure surge can appear in the argon gas in the pipeline, perhaps close argon gas when stopping Argon according to arts demand, argon pressure descends suddenly in the piping system, forms negative pressure, causing gas permeable brick to ooze the steel amount strengthens, influence the use properties of gas permeable brick, even the bleed-out accident can occur, the influence safety in production.

Therefore, need improve existing ladle argon-blown system, can be when argon system pressure fluctuation occurs or stops Argon, guarantee negative pressure can not occur in the gas permeable brick, avoid infiltration of molten steel to enter the gas permeable brick slit to greatest extent, gas permeable brick can be etched because of sepage, thereby avoid ladle the bleed-out accident to occur, guarantee that production safety carries out.

The utility model content

In view of this, the utility model provides a kind of ladle antiseepage argon blowing system, can be when argon system pressure fluctuation occurs or stops Argon, guarantee negative pressure can not occur in the gas permeable brick, avoid infiltration of molten steel to enter the gas permeable brick slit to greatest extent, gas permeable brick can be etched because of sepage, thereby avoid ladle the bleed-out accident to occur, guarantee that production safety carries out.

Ladle antiseepage argon blowing system of the present utility model, comprise source of the gas, described source of the gas is communicated with the argon gas import of air brick of steel ladle, also comprises gas buffer jar and breather cheek valve, and described source of the gas is communicated in the import of air brick of steel ladle argon gas by gas buffer jar and breather cheek valve successively.

Further, described gas buffer jar and breather cheek valve all are fixedly installed on the ladle;

Further, on the described ladle bearing is set, described gas buffer jar is fixedly installed on the ladle by bearing, and breather cheek valve is by be fixedly installed on the gas buffer jar communicating pipe;

Further, described bearing is positioned at ladle bottom.

The beneficial effects of the utility model: ladle antiseepage argon blowing system of the present utility model, advance gas buffer jar and check valve are set on the argon gas pipeline at ladle, closing source of the gas when stopping Argon, pipeline section is a malleation behind the pipeline valve, make closed check valve, avoid because negative pressure makes molten steel enter the gas permeable brick slit; When fluctuation appears in line pressure, because the shock absorption of surge tank, line pressure can fluctuation not occur with system behind the surge tank, thereby can relative negative pressure condition not appear because of the system pressure fluctuation, avoid infiltration of molten steel to enter the gas permeable brick slit to greatest extent, gas permeable brick can be etched because of sepage, thereby avoid ladle the bleed-out accident to occur, guarantee that production safety carries out.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further described.

Accompanying drawing is a structural representation of the present utility model.

Embodiment

Accompanying drawing is a structural representation of the present utility model, as shown in the figure: the ladle antiseepage argon blowing system of present embodiment, comprise source of the gas 1, described source of the gas 1 is communicated with the argon gas import of air brick of steel ladle 3, also comprise gas buffer jar and breather cheek valve, described source of the gas is communicated in the argon gas import of air brick of steel ladle 3 successively by gas buffer jar 6 and breather cheek valve 4.

In the present embodiment, described gas buffer jar 6 and breather cheek valve 4 all are fixedly installed on the ladle 2; Make the equipment overall structure compactness, install and convenient in carrying, be convenient to the Argon operation.

In the present embodiment, on the described ladle 2 bearing 5 is set, described gas buffer jar 6 is fixedly installed on the ladle 2 by bearing 5, and breather cheek valve 4 is by be fixedly installed on the gas buffer jar 6 communicating pipe; Easy installation and removal is simple.

In the present embodiment, described bearing 5 is positioned at ladle 2 bottoms, makes breather cheek valve 4 and gas surge tank 6 apart from gas permeable brick 3 inlet mouth close together, prevents to cause the check valve response lag because of pipeline is long, prevents that further infiltration of molten steel from entering the gas permeable brick slit.

Explanation is at last, above embodiment is only unrestricted in order to the explanation the technical solution of the utility model, although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement the technical solution of the utility model, and not breaking away from the aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of the claim scope of the present utility model.
