Abstract
The invention provides a device for judging leakage amount of a ladle bottom blowing pipeline. The device comprises an argon control system, an argon delivery pipeline, a ladle vehicle carried with ladles, and a leakage detection control valve, wherein the leakage detection control valve is arranged at the end of the argon delivery pipeline, near the ladles. The device for judging the leakage amount of the ladle bottom blowing pipeline adopts a method that a cutoff valve is opened, and if the flow quantity stabilized by a flow quantity adjusting device is 0N1/min, the argon delivery pipeline has no leakage point; if the flow quantity stabilized by the flow quantity adjusting device is greater than 0N1/min, the argon delivery pipeline has a leakage point, and the greater the value is, and the greater the leakage amount is; and if the flow quantity stabilized by the flow quantity adjusting device is smaller than 30N1/min, the production requirements are met, and the finding of a leakage point is not required. The device and the method for judging the leakage amount of the ladle bottom blowing pipeline have the advantages that the leakage point of the ladle bottom blowing pipeline can be quickly judged, the labor strength of operators is reduced, and the production efficiency is improved.
Description
Technical field
The present invention relates to the ferrous metallurgy field, particularly a kind of devices and methods therefor of judging ladle bottom blowing pipeline leakage amount.
Background technology
At present in the molten steel furnace external refining Technology, a kind of means that Argon stirs as refining are widely used in the refinery practices such as ladle argon-blown, LF, VAD, VOD, CAS-OB, can enlarge reaction interface, accelerated reaction process by the Argon stirring, improve speed of response, and the use of ladle bottom blowing argon gas is comparatively general.Because ladle bottom blowing requires argon gas must reach the metallurgical effect that certain pressure and flow could obtain needs, the regulating and controlling device of general argon bottom-blowing is all far away apart from the ladle distance, the air delivering pipeline many places are in the air, and formed by metal hard tube and metallic hose, metallic hose is in use because of the crooked high-temperature steel slag effect with spilling of Tensile, through looking into the generation gas leak phenomenon, in case can not in time find, steel quality and STEELMAKING PRODUCTION are all produced considerable influence.
Summary of the invention
Technical problem to be solved by this invention provides a kind of devices and methods therefor of quick judgement ladle bottom blowing pipeline leakage amount.
For solving the problems of the technologies described above, the invention provides a kind of device of judging ladle bottom blowing pipeline leakage amount, comprise argon gas Controlling System, air delivering pipeline, be loaded with the buggy ladle of ladle and be arranged on air delivering pipeline near the leakage detection by-pass valve control of ladle end, described air delivering pipeline comprises metal hard tube and metallic hose, and described argon gas Controlling System comprises trip valve, tensimeter and the flow regulation device that is successively set on the metal hard tube.
The present invention also provides a kind of method of utilizing said apparatus to judge ladle bottom blowing pipeline leakage amount, comprising:
Close the leakage detection by-pass valve control, utilize flow regulation device to set flow;
Open trip valve, if the flux values after flow regulation device is stablized is 0Nl/min, illustrate that air delivering pipeline is without leak source;
If the flux values after flow regulation device is stable leak source has been described, and the larger expression spillage of numerical value is larger greater than 0Nl/min;
If the flux values after flow regulation device is stable then meets production requirement less than 30Nl/min, do not need to carry out finding leak source.
Further, the described set(ting)value of utilizing flow regulation device to set flow is greater than 200Nl/min.
A kind of devices and methods therefor of judging ladle bottom blowing pipeline leakage amount provided by the invention, can judge fast whether the ladle bottom blowing air delivering pipeline exists leak source, and judge whether and to exert an influence to steel quality and production, judged with the interior spillage that just can finish air delivering pipeline at two minutes generally speaking, provide assurance for reducing labor intensity of operating staff and enhancing productivity.
Description of drawings
A kind of structural representation of judging the device of ladle bottom blowing pipeline leakage amount that Fig. 1 provides for the embodiment of the invention.
Embodiment
Referring to Fig. 1, a kind of device of judging ladle bottom blowing pipeline leakage amount that the embodiment of the invention provides, comprise argon gas Controlling System 1, air delivering pipeline 2, be loaded with the buggy ladle 4 of ladle 3 and be arranged on air delivering pipeline 2 near the leakage detection by-pass valve control 5 of ladle 3 ends, air delivering pipeline 2 comprises metal hard tube 9 and metallic hose 10, and argon gas Controlling System 1 comprises trip valve 6, tensimeter 7 and the flow regulation device 8 that is successively set on the metal hard tube 9.
The using method of the device of judgement ladle bottom blowing pipeline leakage amount provided by the invention is: leakage detection by-pass valve control 5 is in full open position under normal circumstances, use traffic setting device 8 is set certain flow, open trip valve 6, the actual flow that flow regulation device 8 shows should be consistent with the setting flow, as be lower than the setting flow, illustrate that there is obstruction in air delivering pipeline 2, should search blocking position.Judge such as needs whether the bottom blowing pipeline exists gas leak phenomenon, at first make leakage detection by-pass valve control 5 be in buttoned-up status, use traffic setting device 8 is set certain flow, general requirement is greater than 200Nl/min, open trip valve 6, the actual flow that flow regulation device 8 shows generally at first reaches the setting flow, then successively decrease gradually, if arrive at last 0Nl/min, air delivering pipeline 2 good seals are described, without leakage point, otherwise explanation has leak source, and the larger expression spillage of actual flow numerical value after stablizing is larger.Affected by environment and life of equipment at actual STEELMAKING PRODUCTION scene, it is less without the possibility of any leak point that air delivering pipeline 2 reaches, generally all certain spillage can be arranged, need to determine according to the actual process situation whether spillage can meet the requirements, according to on-site experience, think that spillage just can meet the requirements less than 30Nl/min under normal circumstances, do not need to carry out searching of leak source.
A kind of devices and methods therefor of judging ladle bottom blowing pipeline leakage amount provided by the invention, can judge fast whether the ladle bottom blowing air delivering pipeline exists leak source, and judge whether and to exert an influence to steel quality and production, judged with the interior spillage that just can finish air delivering pipeline at two minutes generally speaking, provide assurance for reducing labor intensity of operating staff and enhancing productivity.
It should be noted last that, above embodiment is only unrestricted in order to technical scheme of the present invention to be described, although with reference to example the present invention is had been described in detail, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement technical scheme of the present invention, and not breaking away from the spirit and scope of technical solution of the present invention, it all should be encompassed in the middle of the claim scope of the present invention.
