Definitions
- Coolant nozzle for cooling a metallic strand in a continuous casting plant
- the invention relates to a coolant nozzle for cooling a metallic strand in a continuous casting plant.
- a continuous casting plant - for example for the casting of steel slabs - comprises - in a direction of passage of the strand through the continuous casting plant - inter alia a pan with an outlet tube, a casting distributor arranged below the ladle with a casting tube and a stopper arranged in the casting distributor or another Closure and arranged below the G confuseverteilers and a lower end of the shroud receiving and cooled wide side plates and cooled narrow side plates having mold.
- the ladle contains liquid steel, which is introduced into the casting distributor via the outlet pipe. From the G confuseverteiler turn the liquid steel on the
- Pouring tube is introduced into the mold, wherein a mass flow of the steel flowing into the mold is controlled by means of the plug or other closure.
- the steel cools (primarily) at its contact surfaces with the (cooled) broad side plates and the (cooled) narrow side plates of the mold and solidifies in this case, so that the steel emerges from the mold in the form of a strand having a rectangular cross section.
- the strand is conveyed by means of a strand guiding system through a so-called pouring arc, which is arranged below or below the mold, into a horizontal line. and then the output of the casting arc horizontally further ge ⁇ leads or by strand guide system support elements, ie Rol ⁇ len the strand guiding system, supported and guided or transported from ⁇ .
- the strand is replaced by a liquid coolant (typically water, so-called “water only” cooling) or a mixture of a liquid cooling medium and a gas (so-called “air mist” cooling or air / water spraying) (secondary, “Secondary Cooling "/ secondary cooling) using appropriate (spray) nozzles (" water only "nozzles /” air mist "nozzles) cooled.
- a liquid coolant typically water, so-called “water only” cooling
- a gas so-called “air mist” cooling or air / water spraying
- a following aggregate such as a flame cutting machine, by means of which the strand - for example in the form of slabs - is cut or cut.
- the strand may also be produced by a (different) follow-on aggregate, for example a rolling stand of a casting-rolling mill.
- Composite system can be processed directly without first being cut into pieces.
- Water pressure can be adjusted in a small area.
- the spray pattern is also changed in dependence ⁇ From the water pressure, wherein a uniformkerntem- is not guaranteed temperature of the strand by an inhomogeneous heat dissipation.
- the so-called target "air mist" nozzles of the secondary cooling is to increase a spread between the maximum and minimum flow rate of coolant through the spray nozzle in practice has, however, been found that a hö ⁇ here spreading than 10: 1 for " air mist nozzles or 3: 1 for "water only” nozzles is difficult to reach.
- steel grades lead to overcooling especially of the strand edges and thus to quality losses.
- a disadvantage of these coolant nozzles is that the flow through the coolant nozzles can not be actively set (on), so that, in particular, large spreads between the maximum and the minimum amounts of coolant caused by the coolant
- Coolant nozzles are applied to the strand, can not be realized.
- edge areas of a steel strand need to be cooled much less than the central area of the strand to achieve a constant surface temperature, the use of this secondary cooling leads to overcooling, i. Too strong cooling, the edge areas, under which the quality of the steel strand suffers.
- the coolant nozzle for cooling a metallic strand in a continuous casting plant provides a nozzle disposed at a discharge end of the coolant nozzle mouthpiece, by which liquid coolant, in particular by local mouth piece ⁇ exit opening, from the coolant nozzle exit.
- the spray pattern of the coolant nozzle for example a triangle, a trapezoid or a full or hollow cone, can be determined.
- the mouthpiece may releasable, ⁇ example, using a screw or a threaded the releasable or up / screwable be element ofmémit ⁇ teldüse, it can be so variable - depending upon the intended use - used or exchanged become.
- the mouthpiece on or with a feed in particular a Zuersaustrittsende the feed, this optionally as Is mouthpiece receiver designatable, screwed or bolted there be ⁇ .
- the mouthpiece is designed such that a flow-through cavity in the mouthpiece, ie, the inner cavity in the mouthpiece (between the mouthpiece inlet opening and the mouthpiece outlet opening), through which the liquid coolant flows through the mouthpiece, a small volume has, for example, characterized in that the mouthpiece - in the flow direction ⁇ (the liquid coolant through the mouthpiece) - is formed as short as possible.
- the coolant nozzle has a feed formed as a pipe-in-pipe system, arranged in the flow direction in front of the mouthpiece with a feed exit end, through the first pipe control air to the Zu Replacementsaus ⁇ exit end is approachable and through the second tube, the liquid coolant on the Zu Replacementsaustrittsende the mouthpiece is fed.
- an arrangement of (at least) two tubes ie (at least) a first tube and a second tube, can be understood as a tube-in-tube system, wherein a tube from the (at least) two tubes, for example the first tube, in ⁇ within the other tube of (at least) two tubes, for example, the second tube, is arranged ("tube-In ⁇ tube").
- the first tube in the tube-in-tube system (in the "tube-in-tube” region), the first tube (“inner tube”) (completely surrounded by the second tube) is located in the second tube (as in the example above) ("Outer” or the inner tube surrounding, “outer tube”), which forms a cavity between the outer wall surface ⁇ of the inner tube and the inner Wandflä ⁇ surface of the outer tube.
- an elongated hollow body the length of which is generally much larger than its diameter, may be understood as a tube.
- hoses or tubes for supplying the control air are avoided, whereby the assembly and disassembly of a coolant nozzle in ei ⁇ ner cramped strand guide is much easier.
- the internal supply of the control air also increases the reliability of the coolant nozzle.
- the tube-in-tube system enhances the mechanical strength of the coolant nozzle.
- the tube or the hollow body of the tube-in-tube system or the coolant nozzle may be in one piece, as well as consist of several or many (composite) parts / elements.
- the tube or the hollow body - over its length - variable / changing diameter, ie inner and / or outer diameter, have.
- the first tube and / or the second tube are formed of multiple parts or ⁇ is, in particular such a multi-part excluded are forms or is that their parts are screwed together or welded together.
- the screwable multi-part design of the pipes of the pipe-in-pipe system makes possible an extremely flexible design of the coolant nozzle.
- parts of the coolant nozzle can be easily replaced, which simplifies maintenance.
- This "tube-in-tube” arrangement of the (at least) two tubes in the feed can thus be two flow paths (at / by the feed) - for the control air and for the liquid coolant - form, the first through the inner tube (ie, inside the inner tube) - for the control air - and the second outside of the inner Roh ⁇ res and within the outer tube it, that is, between the externa ⁇ ßeren wall surface of the inner tube and the inner surface of the outer tube Wandflä ⁇ , - Ver ⁇ run - for the liquid coolant.
- the coolant nozzle thus allows - by their structural design of the pipe-in-pipe system in the supply -, the control air, such as instrument air, nitrogen or another, preferably non-combustible, gaseous
- the control air such as instrument air, nitrogen or another, preferably non-combustible, gaseous
- Instrument air is to be understood as meaning a wide variety of gases, such as ambient air, technically pure air and also nitrogen, which are used to control pneumatic valves.
- a concentric tube-in ⁇ tube system may be seen, in which (at least in the "tube In tube "Region), the inner tube - concentric with the outer tube - is arranged in the outer tube.
- the feed is rectilinear or at least one bend is formed bent.
- a length of the feed may be varia ⁇ bel designed.
- the coolant nozzle provides a pneumatic - (Durchhneungsven- til) for controlling the coolant flow through the nozzle before switching valve - by the control air, beispielswei ⁇ se instrument air actuated, can be flowed through by the liquidmémit ⁇ tel.
- pneumatic - Denchdeungsven- til
- This pneumatic switching valve is located at the coolant ⁇ ffendüse at the feed exit end of the supply of the coolant nozzle - and thus - in the flow direction - in front of the mouthpiece of the coolant nozzle.
- the switching valve is integrated into the feed, that is, elements of the switching valve are at the same time also elements of the feed.
- a valve housing - or a part of the valve housing - also an element of the supply, for example, a part of the inner or outer tube, be.
- This "arranged at the Zugarausbergsende" in the switching valve also does not exclude that parts of the switching valve or the switching valve in the whole (in the flow ⁇ direction) are arranged immediately after the Zu enclosuresaustrittsende at this, for example so between the feed exit end and Likewise, parts of the switching valve or the switching valve are or are arranged immediately after the feed exit end at this and already in the area of the mouthpiece inlet / opening.
- this "arranged at the feed exit end" in the switching valve also includes that parts of the switching valve or the switching valve as a whole (in the flow direction) immediately before the Zuzhouauslingersende, ie in the feed or in the pipe In-tube system, are arranged on this or is, for example integrated - as a part of the inner or äuße ⁇ Ren tube - in the feed or in the tube-in-tube system immediately before the Zu arrangementauslingersende.
- the switching valve can thus - accordingly controlled by the control air and actuated - (intermittently) be opened and ge ⁇ closed, whereby the coolant flow or the volume flow of the liquid coolant through the nozzle - depending on a desired cooling capacity - can be controlled or regulated.
- control air is at the - pneumatically actuated by the control air, of the flowing liquid coolant - switching valve, so the switching valve is closed - and the liquiddemit ⁇ tel can not flow through the valve and on to the mouthpiece of the coolant nozzle; if no pilot air to the - pneumatically actuated by the control air, through which the liquid refrigerant - of switching valve, the switching valve is open - and the liquid coolant through the valve and further to the mouthpiece of the coolant nozzle flows ⁇ SEN.
- the application of the control air to the valve can be done using a - especially pneumatically controllable - Vorventils.
- a pressure of the control air is larger than the pressure of - controlled by the switching valve - liquid coolant ⁇ example, 1.5 times as large.
- the actuation of the switching valve such as its (intermittent) opening and closing, by means of a switching element of the switching valve, which may be formed ⁇ example as a valve spool of a spool valve or a control piston of a seat valve, follow, wherein the flow of the cooling medium by the
- Switching valve depending on the position of the switching element is either opened or closed.
- a closed position of the switching element can be understood as that position in which the flow of the cooling medium through the switching valve is closed.
- the switching element By actuation of the switching element - upon actuation of the switching valve or during opening and closing of the switching valve Tils by the control air - the switching element is typically ⁇ shifted, especially in or against the flow ⁇ direction of the liquid coolant through the coolant nozzle, and then closes / blocks the coolant flow through the coolant nozzle and releases it.
- switch valves are known, in de ⁇ NEN the switching element is rotated when actuated. It is basically possible to perform the switching valve as a shift ⁇ berventil or as a seat valve.
- An advantage of the design as a seat valve is that the cooling medium is sealed leak-free without further valves and that a higher insensitivity to pollution is given.
- the switching element comprises a control piston, wherein a (wave) bellows or a membrane the control ⁇ piston - in particular with respect to the supply, for example, the inner and / or the outer tube, or the valve housing - leads and optionally seals.
- the membrane or the (corrugated) bellows is made of stainless metal, preferably steel, or of plastic, preferably heat-resistant plastic, which has significant strengths up to temperatures greater than 250 ° C, such as e.g. Polyimide or polyaryletherketone (PEEK).
- PEEK polyaryletherketone
- the (wave) of the bellows pipe-in-pipe system is concentric to the first inner tube and at ⁇ sorted, in particular on a blow as a Wellenbalgan- formed second part of the inner tube angeord ⁇ net, whereby the (wave) bellows axially relative to the inner Ren tube, in particular to the Wellenbalganschlag, can be guided.
- the inner and ers ⁇ te pipe constitutes a kind of linear guide for the (wave) is bellows.
- the feed outlet end in particular the mouthpiece receiver, as is a valve seat for the switching element of the switching valve, in particular for the control piston of the seat valve, Schaubil ⁇ det, can be as a very small-sized coolant nozzle imple- mented be.
- a material of the switching element, in particular of the control piston, and a material of the valve seat are matched, in particular that the valve seat has a lower hardness than the switching element or that the valve seat has a higher hardness than the switching element
- the tightness of the valve and also its life can be increased by such pairing of materials.
- a, in particular screwed to the feed, terminal block which in particular has a first connection for the control air and / or a second connection for the liq ⁇ sige coolant.
- the terminal block may further include a first passageway, using which the first port is connectable to the first inner tube of the feeder, and / or having a second passageway, by means of which the second port is connectable to the second tube of the feeder.
- a cooling device for cooling a metal strand which auffactfol ⁇ quietly arranged more in the strand conveying direction, in particular extending transversely to the strand conveying ⁇ directional nozzle units, for example, several spray bars, having.
- Each of these nozzle unit or each spray bar can then provide at least one first such coolant nozzle and a second such coolant nozzle, as described be ⁇ .
- each of these nozzle unit or each such spray bar also provide a plurality or a plurality of such coolant nozzles.
- the option (be ⁇ true) coolant nozzles to specific groups such as the edge nozzles (for edge areas of the strand) or SI ⁇ sen for a central area in the center of the strand, together.
- a common control air supply can then sit a pilot valve for the (on) control of a whole such nozzle group.
- the first coolant nozzles of the plurality of nozzle units can be supplied with the control air via a first common control air supply with the control air and / or the second coolant nozzles of the plurality of nozzle units via a second common control air supply.
- control air supply in the first common control air supply is controlled using a first control valve arranged in the first common control air supply and / or the
- Control air supply is controlled in the second common control air supply using a second control valve arranged in the second common control air supply.
- the coolant nozzle described - in a sole arrangement and also in parent compilation / - circuit has many special advantages by their construction.
- the coolant nozzle allows - by their structural design - to bring the control air and the liquid coolant just behind the nozzle exit end, ie to the mouthpiece, so that the full pressure of the liquid coolant with open switching valve immediately (except for small pressure drops in the switching valve, the However neglected who can ⁇ the) is applied to the coolant nozzle or a rapid pressure build-up of the liquid coolant in the coolant nozzle is possible, so that a constant spray pattern is ensured even at low ⁇ cal cooling performance.
- coolant nozzle is by no means limited to a “water on” nozzle, but of course, an “air mist” nozzle can also be used.
