Opfindelsen angår en fremgangsmåde og et apparat til påføring af en loddemetal belægning på en metalli seret rand af en glasplade eller en plade af glaslignende materiale, hvor pladens randområde forsynes med smeltet loddemetal, og det smeltede loddemetal strømmer over 5 pladens kant.BACKGROUND OF THE INVENTION The invention relates to a method and apparatus for applying a solder coating to a metallized edge of a glass plate or a sheet of glass-like material, wherein the edge region of the plate is provided with molten solder and the molten solder flows over the edge of the plate.
Opfindelsen finder navnlig anvendelse inden for området med: flerlagede glaspladekonstruktioner, hvor glasplader eller plader af glaslignende materiale sammenloddes direkte med hinanden, eller hvor 10 glasplader eller plader af glaslignende materiale holdes i afstand fra hinanden ved hjælp af derimellem liggende metal afstandsstykker, som er sammenloddet med de metalliserede rande. En sådan sammenlodning kan gennemføres på den måde, at der kun anvendes loddemetal, som forud er påført pladerandene og/eller eventuelt de forhånden-15 værende afstandsstykker. Der kan imidlertid også påføres yderligere loddemetal.The invention is particularly applicable in the field of: multilayer glass sheet structures where glass sheets or sheets of glass-like material are directly bonded to each other or where 10 glass sheets or sheets of glass-like material are spaced apart by means of spaced metal spacers interlaced with the metallized edges. Such soldering can be carried out in that only solder which is applied to the plate edges and / or optionally the pre-existing spacers is used. However, additional solder can also be applied.
Der er allerede fremsat forskellige forslag til påføring af et loddemetal på sådanne metalliserede pladekanter. Til at begynde med 20 blev sådanne loddemetal belægninger fremstillet manuelt ved, at loddemetallet blev smeltet in situ. Dette var overordentligt arbejdskrævende, dyrt og tidsrøvende. Som følge heraf blev der gjort forskellige anstrengelser for at mekanisere denne arbejdsoperation.Various proposals have already been made for the application of a solder to such metallized sheet metal edges. For starters, such solder coatings were made manually by melting the solder in situ. This was extremely labor intensive, expensive and time consuming. As a result, various efforts were made to mechanize this work operation.
25 Et sådant forslag er beskrevet henholdsvis i GB patentskrift nr. 1,418,827 og DE offentliggørelsesskrift nr. 2308021. Ifølge dette tidligere forslag påførtes loddemetallet i smeltet form i form af smådråber, og derefter blev dråberne udglattet ved hjælp af en opvarmet sko på en sådan måde, at der blev dannet en belægning, der 30 var mere eller mindre ensartet. Herved er der også mulighed for påsprøjtning af smeltet loddemetal på en smal stribe af randen, hvorved det tillades, at loddemetallet udbreder sig ved overfladespændingsvirkning. Også her opnås der en mere eller mindre ensartet belægning.Such a proposal is disclosed in GB Patent Specification No. 1,418,827 and DE Publication Publication No. 2308021. According to this previous proposal, the solder was applied in molten form in the form of droplets, and then the droplets were smoothed by means of a heated shoe in such a manner. that a coating was formed which was more or less uniform. In this way, it is also possible to spray molten solder onto a narrow strip of the rim, allowing the solder to propagate by surface tension effect. Here, too, a more or less uniform coating is obtained.
35 I DE fremlæggelsesskrift nr. 1596823 er der afsløret en fremgangsmåde til fortinning af på forhånd forkobrede randområder af en glasplade til fremstilling af en dobbeltlaget glaskonstruktion. I dette tilfælde påføres smeltet tin i form af en i forhold til35 in German Patent Specification No. 1596823 discloses a method for diluting pre-cut edge areas of a glass sheet to produce a double layer glass structure. In this case, molten tin is applied in the form of a relative to
DK 158093 BDK 158093 B
2 pladefladerne hældende stråle under tryk på pladeranden. Tin, som strømmer af glaspladen, opfanges i en beholder for genanvendelse.2 The plate faces inclined beam under pressure on the plate edge. Tin flowing from the glass plate is trapped in a container for recycling.
Til opretholdelse af de ønskede temperaturbetingelser findes der brændere. Ifølge dette fremlæggelsesskrift påføres glaspladen mere 5 tin end, hvad der er nødvendigt til fortinning af randområdet, og derfor bliver en del af tinnet genanvendt. I dette fremlægge!ses-skrift er det imidlertid ikke foreslået at påføre loddemetallet langs pladeranden med overskud og mekanisk at indstille belægningens tykkelse ved mekanisk fortrængning af overskuddet. Ifølge dette 10 fremlæggelsesskrift forbliver den påførte loddemetalmængde på pladeranden. Påvirkningen af belægningens tykkelse sker ved indstilling af temperaturen, strålens hældningsvinkel, tinstrålens tryk og pladens bevægelseshastighed. Disse indstillinger er vanskelige, og de er meget vanskelige at reproducere.Burners are available to maintain the desired temperature conditions. According to this disclosure, the glass plate is applied to more 5 tin than is necessary for dilution of the edge area, and therefore part of the tin is recycled. However, in this disclosure, it is not proposed to apply the solder along the sheet edge with excess and to mechanically adjust the thickness of the coating by mechanical displacement of the excess. According to this disclosure, the applied solder amount remains on the sheet edge. The thickness of the coating is influenced by the setting of the temperature, the angle of inclination of the beam, the pressure of the tin beam and the speed of movement of the plate. These settings are difficult and they are very difficult to reproduce.
1515
Det fremgår således heraf, at der i dette kendte tilfælde skal foretages forskellige reguleringsoperationer i det øjeblik, tinnet påføres, for at den påførte tinmængde svarer til den ønskede endelige tinmængde. Så snart tinnet er påført pladeranden, kan der ikke 20 længere træffes nogen foranstaltninger til at påvirke belægningens tykkelse.It is thus apparent from this that in this known case various control operations must be performed as soon as the tin is applied in order that the amount of tin applied corresponds to the desired final amount of tin. Once the tin is applied to the sheet edge, no further measures can be taken to affect the thickness of the coating.
Den foreliggende opfindelse har til formål at anvise en anden fremgangsmåde til påføring af en loddemetal belægning på metallise-25 rede pladerande samt et apparat til udøvelse af denne fremgangsmåde, som muliggør en ensartet kvalitet af belægningen på en lettere måde.The present invention has for its object to provide another method for applying a solder coating to metallized sheet metal edges and an apparatus for practicing this method which allows for a uniform quality of coating in a lighter manner.
Til opnåelse af dette formål består opfindelsen ved en fremgangsmåde af den indledningsvist angivne art i det væsentlige i, at der 30 tilføres et overskud af smeltet loddemetal langs pladeranden, og at det på denne måde tilførte loddemetal bearbejdes i smeltet tilstand med en rakel på en sådan måde, at overskydende mængder af det smeltede loddemetal kontinuerligt ledes hen til pladens kant og bort over denne.In order to achieve this object, the invention, by a method of the kind initially described, consists essentially in supplying an excess of molten solder along the sheet edge and that the solder thus supplied is processed in a molten state with a blade in such a manner. means that excess amounts of the molten solder are continuously directed to the edge of the plate and over it.
35 I kraft af opfindelsen kan der anbringes en ensartet belægning af loddemetal på metalliserede pladerande med høj kvalitet. Opfindelsen letter endvidere anbringelse af loddemetal belægninger med ønsket tykkelse navnlig anbringelsen af tykke belægninger på metalliseredeBy virtue of the invention, a uniform coating of solder can be applied to high quality metallized sheet metal edges. The invention further facilitates the application of solder coatings of the desired thickness, in particular the application of thick coatings to metallized

3 pladerande.3 plates.
Den ifølge opfindelsen foreslåede fremgangsmåde fører af sig selv til en mekanisering. Da det i hvert tilfælde er nødvendigt at 5 transportere glaspladen eller den glaslignende plade fra en bearbejdningsstation til den næste, når der skal fremstilles flerlagede pladekonstruktioner, er det særlig simpelt at anbringe en loddemetal tilførsel sindretning og en rakel over en transportør i en sådan stilling, at randen af en plade automatisk belægges med loddemetal, 10 når denne plade bevæges langs transportøren.The process proposed according to the invention by itself leads to a mechanization. Since in each case it is necessary to transport the glass plate or the glass-like plate from one processing station to the next, in order to produce multilayer plate structures, it is particularly simple to place a solder feed device and a rack over a conveyor in such a position. that the rim of a plate is automatically coated with solder 10 when that plate is moved along the conveyor.
Når der skal gennemføres en loddemetal belægning af randene på rektangulære plader, hvilket jo hovedsagligt er tilfældet, kan der naturligvis anbringes en anden loddemetal tilførsel sindretning og en 15 anden rakel for samtidig at belægge den overfor liggende rand af pladen.Of course, when a solder coating of the edges has to be carried out on rectangular plates, which is mainly the case, a second solder feeding device and a different blade can be applied to simultaneously coat the opposite edge of the plate.
Det ligger naturligvis inden for opfindelsens rammer kun at belægge et metal li seret randområde af en glasplade eller en glaslignende 20 plade med loddemetal. Det er dog i praksis en betingelse, at de rande, der strækker sig langs en plades fulde omfang, er metallise-ret og skal belægges med loddemetal. Forskellige rande af en plade kan metal!iseres i forskellige trin og belægges med loddemetal, og det er ikke nødvendigt, at den samlede metal!i seringsoperation 25 afsluttes, før loddemetallet anbringes på pladen. Ved en foretrukken fremstillingsfremgangsmåde til bearbejdning af rektangulære glasplader eller glaslignende plader transporteres pladerne efter hinanden gennem fire bearbejdningsstationer. Ved den første station metalliseres en rand og belægges derefter med loddemetal. Efter 30 transporten af pladen metalliseres den overfor liggende rand, og denne rand bliver derefter belagt med loddemetal i en anden station. Transportøren ændrer derefter sin retning 90° for at transportere pladen gennem en tredie station, i hvilken den ene af de to tilbageværende rande metalliseres og belægges med loddemetal, og derefter 35 følger der en transport til en fjerde station, i hvilken den sidste pladerand metalliseres og belægges med loddemetal. Det skal bemærkes, at en sådan plade også alternativt kan transporteres to gange gennem hver af to stationer for metallisering af pladens fire rande og belægning af disse med loddemetal.Of course, it is within the scope of the invention to coat only a metal lined rim area of a glass plate or a glass-like plate with solder. However, in practice, it is a condition that the edges extending along the full extent of a plate are metallized and must be coated with solder. Different edges of a plate can be metalized at different stages and coated with solder, and it is not necessary that the total metal in coating operation 25 be completed before the solder is applied to the plate. In a preferred manufacturing method for machining rectangular glass sheets or glass-like sheets, the sheets are conveyed one after the other through four processing stations. At the first station, a rim is metallized and then coated with solder. After the transport of the plate, the opposite edge is metallized and this edge is then coated with solder in another station. The conveyor then changes its direction 90 ° to transport the plate through a third station in which one of the two remaining edges is metallized and coated with solder, and then a transport is followed to a fourth station in which the last plate edge is metallized and soldered. It should be noted that such a plate may also alternatively be transported twice through each of two stations for metallizing the four edges of the plate and coating them with solder.

Det skal endvidere bemærkes, at loddemetal belægni ngen, som påføres ifølge opfindelsen, ikke behøver fuldstændigt at dække det metalliseringslag, hvorpå den anbringes. En sådan fuldstændig tildækning foretrækkes ikke, når man arbejder ifølge den i det foregående 5 beskrevne fremgangsmåde, og dette gælder navnlig de belægninger, der påføres i den første og den anden arbejdsstation. I dette tilfælde foretrækkes det at efterlade en sti be af hvert metal!i seringslag ubelagt, således at de efterfølgende påførte metal!i seringsstriber kan forbindes direkte med de først påførte striber ved pladens 10 hjørner.Furthermore, it should be noted that the solder coating applied according to the invention need not completely cover the metallization layer on which it is applied. Such complete coverage is not preferred when operating according to the method described in the previous 5, and this is particularly true of the coatings applied in the first and second workstations. In this case, it is preferable to leave one strip of each metal in the coating layer uncoated so that the subsequently applied metal in the coating strips can be directly connected to the first applied stripes at the corners of the plate 10.
Det smeltede loddemetal kan påføres den metalliserede pladerand dråbevist eller ved påsprøjtning. Det foretrækkes imidlertid at tilføre en loddemetal stråle fra en dyse.The molten solder can be applied dropwise to the metallized sheet metal or by spraying. However, it is preferred to apply a solder jet from a nozzle.

Ifølge nogle udførelsesformer for den foreliggende opfindelse anvendes der en fast rakel (f.eks. af polytetraflourethylen). Fortrinsvis er raklen imidlertid en gas- eller gasstrålerakel. Ved at anvende en gasrakel er det lettere at indstille tykkelsen af den 20 påførte loddemetal belægning. Endvidere har det vist sig, at en gasrakel muliggør en forbedret overfladetilstand og en forbedret ensartethed af loddemetal belægningen, og dette gælder navnlig ved tykke belægninger. Det har ligeledes vist sig, at anvendelsen af en gasrakel muliggør en forbedret kvalitet af forbindelsen mellem 25 glaspladen og en konstruktionsdel, hvortil pladens rand skal loddes, da faren for, at denne rand skal blive beskadiget, formindskes.According to some embodiments of the present invention, a solid doctor blade (e.g., polytetrafluoroethylene) is used. Preferably, however, the rocket is a gas or gas jet rocket. By using a gas doctor, it is easier to adjust the thickness of the applied solder coating. Furthermore, it has been found that a gas doctor allows an improved surface condition and an improved uniformity of the solder coating, and this is especially true for thick coatings. It has also been found that the use of a gas doctor enables an improved quality of connection between the glass plate and a structural part to which the edge of the plate must be soldered, as the danger of this edge being damaged is reduced.
Gasraklen er fortrinsvis anbragt på en sådan måde, at den afgiver en gasstrøm mod pladeranden langs et langstrakt påblæsningsområde, der 30 danner en spids vinkel med underlagets kant, hvor denne vinkel omslutter tilførselszonen for det smeltede loddemetal. Den spidse vinkel ligger fortrinsvis mellem 70 og 90°.The throttle is preferably arranged in such a way that it dispenses a gas stream against the sheet edge along an elongate blowing area forming a pointed angle with the edge of the substrate, this angle enclosing the feed zone of the molten solder. The acute angle is preferably between 70 and 90 °.
Opfindelsen omfatter også et apparat til udøvelse af den i det 35 foregående beskrevne fremgangsmåde med en understøtning, der danner et forudbestemt sted for en plade, en indretning til forsyning af et randområde på en af understøtningen båret plade med smeltet loddemetal og en indretning til tilvejebringelse af en relativ bevægelse af en af understøtningen båret plade ogThe invention also includes an apparatus for practicing the method described above with a support forming a predetermined location for a plate, a device for supplying an edge area on a plate supported by molten solder and a device for providing a relative movement of a plate and plate supported by the support

5 loddemetal tilførsel sindretningen. Opfindelsen består herved i det væsentlige i, at apparatet har en til loddemetal tilførsel sindretningen hørende rakel, som er anbragt på en sådan måde, at overskydende mængder af smeltet loddemetal ledes hen til kanten af pladen 5 og bort over denne. Dette er et simpelt og hensigtsmæssigt apparat til udøvelse af fremgangsmåden ifølge opfindelsen.5 solder supply the mind device. The invention hereby consists essentially in the fact that the apparatus has a solder feeder, which is arranged in the case of the solder, which is arranged in such a way that excess amounts of molten solder are passed to the edge of the plate 5 and over it. This is a simple and convenient apparatus for practicing the method of the invention.
Fortrinsvis er raklen en gas- eller gastrålerakel. Denne er hensigtsmæssigt anbragt på en sådan måde, at en gasstrøm rettes mod en 10 rand af pladen langs et langstrakt område, der danner en spids . vinkel med pladens kant, hvor denne vinkel omslutter den ortogonale projektion af loddemetal tilførsel sindretningens afgivelsesende på pladens plan. Den spidse vinkel ligger fortrinsvis i området mellem 70 og 90°. Indretningerne til dannelse af gasraklen har hensigts-15 mæssigt en blok, der har en slidseåbning, og der findes indretninger tilførsel af gas, der står under tryk, til denne blok, for at denne luft kan strømme ud gennem denne slids.Preferably, the rocket is a gas or gas jet rocket. Conveniently, this is arranged in such a way that a gas stream is directed to a rim of the plate along an elongate region forming a tip. angle with the edge of the plate, where this angle encloses the orthogonal projection of solder supply the discharge end of the device on the plane of the plate. The acute angle is preferably in the range between 70 and 90 °. Conveniently, the gas burner generating devices have a slot having a slot orifice, and pressurized gas supply devices are provided for this block to allow this air to flow through this slot.
En foretrukken udførelsesform for opfindelsen skal herefter beskri-20 ves nærmere under henvisning til tegningen, hvor fig. 1, 2 og 3 viser henholdsvis et endebillede, et billede set fra oven og et sidebillede af en loddemetaltilførsel sindretning og en tilhørende rakel.A preferred embodiment of the invention will now be described in more detail with reference to the accompanying drawing, in which: FIG. 1, 2 and 3 show an end view, a top view, and a side view, respectively, of a solder feeding device and an associated doctor blade.

Som det er vist i fig. 2 er længdeaksen for slidsen 10's åbning anbragt under en 15 vinkel på 6“ i forhold til normalen til pladen 6's kant 7 og danner derfor en spids vinkel på 84° med denne kant. Denne spidse vinkel omslutter tilførselszonen for det smeltede loddemetal, og den vinkelrette projektion af dysen 4 ved udløbsenden af 1 oddemetal ti 1-førselsindretningen 1 på pladens plan.The slot 10 in the gas groove 8 has an elongate opening formed in such a way that a gas flow is released vertically downwards towards an elongate region at the rim 5 of the plate 6. As shown in FIG. 2, the longitudinal axis of the opening of the slot 10 is positioned at an angle of 6 "to the normal of the edge 7 of the plate 6 and therefore forms an acute angle of 84 ° with this edge. This acute angle encloses the feed zone of the molten solder and the perpendicular projection of the nozzle 4 at the outlet end of 1 odd metal to the 1 feed device 1 on the plane of the plate.

Loddemetal tilførselsindretningens cylindriske konstruktionsdel 2 kan være forsynet med opvarmningsmekanismer for at holde loddemetallet, som strømmer gennem boringen 3 på en passende temperatur. Yderligere eller alternativt kan denne konstruktionsdel 2 være varmei soleret.The solder metal cylindrical assembly part 2 of the soldering device may be provided with heating mechanisms to keep the solder metal flowing through the bore 3 at an appropriate temperature. Further or alternatively, this structural part 2 may be heat insulated.
25 Under drift kan loddemetallet tilføres boringen 3 under påvirkning af tyngdekraften fra en ikke-vist opvarmet digel, og overskydende loddemetal, som strømmer ud over pladens kant, opfanges fortrinsvis i en ikke-vist overstrømningsbeholder. Denne overstrømningsbeholder kan ligeledes være opvarmet for at holde loddemetallet i smeltet 30 tilstand, og dette overskydende loddemetal kan føres tilbage til den opvarmede digel for genanvendelse.In operation, the solder can be applied to the bore 3 under the influence of gravity from a non-displayed heated crucible, and excess solder flowing beyond the edge of the plate is preferably trapped in a non-shown overflow vessel. This overflow vessel may also be heated to keep the solder in the molten state and this excess solder may be returned to the heated crucible for recycling.
Ved en foretrukken udførelsesform for apparatet har boringen 3 en længde på 12 til 15 cm, og dysen 4 har en indvendig diameter på 35 3,5 mm.In a preferred embodiment of the apparatus, the bore 3 has a length of 12 to 15 cm and the nozzle 4 has an internal diameter of 35 3.5 mm.
Den nederste kant af dysen 4's munding er anbragt i en afstand på 4 mm over pladen 6's overflade, der har en metalliseret rand, der er 10 til 12 mm bred, og som har en tykkelse på 5 til 15 pm. For atThe lower edge of the mouth of the nozzle 4 is spaced 4 mm above the surface of the plate 6, which has a metallized rim 10 to 12 mm wide and having a thickness of 5 to 15 µm. To

7 belægge hele bredden af en på denne måde metal! i seret rand med loddemetal, anbringes dysen 4 med den ortogonale projektion af midten af dens dyseåbning på pladen ca. 13 mm inden for pladens kant d.v.s. fjernet i en afstand på ca. 1 til 3 mm fra fra metal li serin-5 gen 5's inderrand. Som beskrevet i det foregående er det hyppigt fordelagtigt ikke at belægge hele den metalliserede rand med loddemetal for at tilvejebringe et forbindelsessted for en tilsluttende, udskilt metalliseringsbelægning. I disse tilfælde er dysen anbragt tættere ved pladens kant for at efterlade en ikke-belagt metallise-10 ret stribe, der f.eks. har en bredde på 2 til 3 mm eller mere. Dysen kan tilføre loddemetal ved hjælp af en trykhøjde på 40 cm for tilvejebringelse af et tryk på ca. 39,23 kPa, således at loddemetalstrålen træder ud af dysen i en mængde på 8,2 cm3/s.7 coat the entire width of a metal like this! in soldered rim with solder, the nozzle 4 with the orthogonal projection of the center of its nozzle opening is placed on the plate approx. 13 mm within the edge of the plate i.e. removed at a distance of approx. 1 to 3 mm from the inner rim of the metal of serine 5 gene 5. As described above, it is often advantageous not to coat the entire soldered metal with solder to provide a connection site for a subsequent, separated metallization coating. In these cases, the nozzle is positioned closer to the edge of the plate to leave an uncoated metallized strip, e.g. has a width of 2 to 3 mm or more. The nozzle can supply solder with a pressure height of 40 cm to provide a pressure of approx. 39.23 kPa, so that the solder jet exits the nozzle in an amount of 8.2 cm3 / s.
15 De optimale tykkelser af det påførte loddemetal!ag afhænger i vidtgående omfang af de følgende montageoperationer. Hvis man f.eks. betragter en dobbeltplade, hvor et metal afstandsstykke indloddes mellem metalliserede og loddemetal bel agte rande af to glasplader, kan lodningen af afstandsstykket til pladerne gennemføres med eller 20 uden anbringelse af yderligere loddemetal.The optimum thicknesses of the applied solder agar depend to a large extent on the following mounting operations. For example, if Considering a double plate in which a metal spacer is opened between metallized and soldered edges of two glass plates, the soldering of the spacer to the plates can be carried out with or without the application of additional solder.
F.eks. kan en flad blyafstandsstrimmel indloddes kantsti 11 et mellem to plader ved hjælp af 1 oddemetalvulster, der anbringes i et trin, som slutter sig til belægningstrinet. I dette tilfælde kan den 25 loddemetal belægning, der blev påført ifølge den foreliggende opfindelse, kun være en tynd belægning og bør kun have en tykkelse på mellem 20 til 25 μηι. Ved en anden fremstillingsfremgangsmåde sammenloddes et loddemetal bel agt fl angeformet afstandsstykke med sin flange med fladeanlæg med den loddemetal bel agte metalliserede rand 30 på to plader. Dette sker uden tilsætning af nogen form for yderligere loddemetal ved, at konstruktionsgruppen sammenspændes og opvarmes for at smelte de tidligere påførte loddemetal belægninger. I dette tilfælde er det ønskeligt, at loddemetal belægningerne på pladerandene er tykkere og f.eks. har tykkelser inden for området 35 100 til 200 jan.Eg. For example, a flat lead spacer strip may be opened to edge path 11 between two plates by means of 1 odd metal beads placed in a step joining the coating step. In this case, the 25 solder coating applied in accordance with the present invention may be only a thin coating and should only have a thickness of between 20 and 25 μηι. In another manufacturing method, a solder-like flanged spacer is welded together with its flange with flange with the solder-coated metallized rim 30 on two plates. This is done without the addition of any additional solder by compressing and heating the structural group to melt the previously applied solder coatings. In this case, it is desirable that the solder coatings on the sheet edges be thicker and e.g. has thicknesses in the range 35 100 to 200 Jan.
I et fremstillingsanlæg kan glasplader eller glaslignende plader transporteres langs en produktionslinie med en hastighed på 22 m/min., og denne hastighed bestemmes f.eks. af de metalliserings-In a manufacturing plant, glass plates or glass-like plates can be transported along a production line at a speed of 22 m / min, and this speed is determined e.g. of the metallization

Påføringen af en 200 /im tyk og 12 mm bred belægning sker under anvendelse af indtil 0,88 cm3/s smeltet loddemetal, hvilket betyder 11% af den påførte mængde (med en strømningsmængde på 8,2 cm3/s). Resten af loddeme-5 tallet ledes ved hjælp af gasraklen ud over kanten af pladen og tilbageføres.8 and washing operations to be performed. A 200 µm thick and 12 mm wide coating is applied using up to 0.88 cm 3 / s molten solder, which means 11% of the applied amount (with a flow rate of 8.2 cm 3 / s). The remainder of the solder number is guided by the throttle beyond the edge of the plate and returned.
En sådan loddemetal belægningstykkelse kan let opnås ved, at der anvendes en gasrakel, der har en tilsvarende udformet slidseåbning.Such a solder coating thickness can be readily obtained by using a gas doctor having a similarly designed slot opening.
10 Endvidere er der tilvejebragt en egnet afstand fra pladeranden og en egnet gasstrømningsmængde og et egnet tryk.Furthermore, a suitable distance from the sheet edge and a suitable gas flow rate and pressure are provided.
Som udførelseseksempel er der givet forskellige parametre for sådanne gasrakler i den følgende tabel.As an example, various parameters for such gas blasts are given in the following table.
