Description
Fremgangsmåte for oppvikling og eventuell kjøling av varmvalset materiale samt anordning for utførelse av fremgangsmåten. Procedure for winding and possibly cooling hot-rolled material as well as device for carrying out the procedure.
Foreliggende oppfinnelse vedrorer en fremgangsmåte for oppvikling og eventuell kjoling av varmvalset materiale, hvor materialets forende fores fra et sluttvalsepar gjennom et lederor til en oppfangningsdel for en roterbar vinde, idet materialet ved friksjon fester seg i vinden efter noen vindinger, samt en anordning for utfdreise av fremgangsmåten. The present invention relates to a method for winding and possible cooling of hot-rolled material, where the front end of the material is fed from a pair of final rolls through a guide tube to a catch part for a rotatable wind, the material being stuck in the wind by friction after a few turns, as well as a device for ejecting the procedure.
Produsenter av valsetråd og spesielt trådtrekkeriene krever stadig storre ringvekter for å rasjonalisere fremstillingen, og fordringene til jevn struktur efter hele trådens lengde er dessuten blitt skjerpet for. visse trådkvaliteter. Manufacturers of wire rod, and wire drawing mills in particular, require ever larger ring weights to rationalize production, and the requirements for a uniform structure along the entire length of the wire have also become more stringent. certain thread qualities.
Den onskede storre ringvekt har hittil bare kunnet tilfredsstil-Kfr. kl. 47k-5/02 les med storre ringdiametre og hoyere ringer. Disse ringer blir uhåndterlige og gir storre forskjell i avkjolingstid for vindinger midt inne i ringen og ved overflaten. The desired larger ring weight has so far only been able to satisfy - Kfr. at 47k-5/02 read with larger ring diameters and taller rings. These rings become unmanageable and give a greater difference in cooling time for windings in the middle of the ring and at the surface.
Ved de konvensjonelle fremgangsmåter for varmvikling med anvend-else av Garret- eller Edenborn-vinder holder volumvekten seg for en ring med 5,5 mm tråd på 1 å 1,5 kg/dm 3. Formålet med oppfinnelsen er å tilveiebringe storre ringvekter med mindre ringdimen-sjoner og samtidig å tilveiebringe en kontrollert kjoling ned til en sådan gjennomsnittstemperatur at strukturen blir den samme langsefter trådens eller profilens hele lengde. With the conventional methods for hot winding using Garret or Edenborn windings, the volume weight for a ring with 5.5 mm wire is 1 to 1.5 kg/dm 3. The purpose of the invention is to provide larger ring weights with less ring dimensions and at the same time to provide a controlled cooling down to such an average temperature that the structure becomes the same along the entire length of the wire or profile.
Dette oppnås ved at det varmvalsede materiale på sin vei fra sluttvalseparet til vinden bringes til å passere en reguleringsanordning med trådbuktavsokende organ for justering av sluttvalseparets hastighet og at lederoret bringes til å bevege seg frem og tilbake i vindens aksialretning slik at materialet spoles i lag efter lag ved vindens bevegelse for oppnåelse av onsket viklingstetthet, samt at kjolemiddel ved behov tilfores for hensiktsmessig nedkjoling av den frie flate av de således dannede vindinger. This is achieved by causing the hot-rolled material on its way from the final roller pair to the wind to pass a regulating device with a wire bend detecting device for adjusting the speed of the final roller pair and for the guide rod to move back and forth in the axial direction of the wind so that the material is wound in layer after layer by the movement of the wind to achieve the desired winding density, and that a cooling agent is supplied if necessary for appropriate cooling of the free surface of the windings thus formed.
Hvis man valser 5 mm tråd i 1000 kg ringvekt = 6500 m. varm lengde ved 35 m/s fås teoretisk 19,4 t/h. Med, en midlere ringdiameter på 1115 mm = 3,5 m omkrets og 500 mm ringhoyde fås 100 vindinger/ trådlag og 18,6 trådlag = 95 mm ringtykkelse. Det tar IO s for å tettvikle et lag og folgelig kan trådviklingens sist påviklede lag kjoles i gjennomsnittlig 10 s. Ved tettvikling ifolge denne fremgangsmåte oppnår man ved rund ståltråd en teoretisk volum-vekt på • t^ r . 7,8 = 6,1 kg/dm 3 og man får tilstrekkelig kjolings-tid til en kontrollert kjoling ned til eksempelvis 600°C. If you roll 5 mm wire in 1000 kg ring weight = 6500 m. hot length at 35 m/s theoretically 19.4 t/h is obtained. With an average ring diameter of 1115 mm = 3.5 m circumference and 500 mm ring height, 100 turns/wire layer and 18.6 wire layers = 95 mm ring thickness are obtained. It takes 10 s to tightly wind a layer and consequently the last wound layer of the wire winding can be wound in an average of 10 s. When tightly wound according to this method, round steel wire achieves a theoretical volume weight of • t^ r . 7.8 = 6.1 kg/dm 3 and you get sufficient cooling time for a controlled cooling down to, for example, 600°C.
Hvis man valser 25 mm tråd,i 2000 kg ringvekt =518 m varmlengde ved 3,5 m/s fås teoretisk 48,6 t/h. Med en midlere ringdiameter på 1115 mm = 3,5 m omkrets og 500 mm ringhoyde fås 20 vindinger/ trådlag og 7,4 trådlag = 200 mm ringtykkelse. Det tar 20 s for å tettvikle et trådlag og gjennomsnittlig 20 s står folgelig til disposisjon for kjoling av trådvindingenes sist viklede overflate. If you roll 25 mm wire, in 2000 kg ring weight = 518 m hot length at 3.5 m/s, theoretically 48.6 t/h is obtained. With an average ring diameter of 1115 mm = 3.5 m circumference and 500 mm ring height, 20 turns/wire layer and 7.4 wire layers = 200 mm ring thickness are obtained. It takes 20 s to tightly wind a wire layer and an average of 20 s is therefore available for dressing the last wound surface of the wire windings.
Oppfinnelsen vises i fig. 1-3, hvor The invention is shown in fig. 1-3, where
Fig. 1 viser et horisontalriss av en trådvinde. Fig. 1 shows a horizontal view of a wire winder.
Fig. 2 er et snitt efter linjen II-II i fig. 1. Fig. 2 is a section along the line II-II in fig. 1.
Fig. 3 er et snitt efter linjen III-III i fig. 2. Fig. 3 is a section along the line III-III in fig. 2.
I fig. 1 er 1 en valsetråd som fores mellom ytre og indre flen-ser 2 og 3 i en styrerenne, gjennom et lederor 6 til en vinde. Lederoret 6 kan bevege seg vinkelen 61, fig. 2, f.eks. ved hjelp av en motor 64, en skrue 63 og en mutter 62. In fig. 1, 1 is a roller wire which is fed between outer and inner flanges 2 and 3 in a guide channel, through a guide tube 6 to a winding. The guide rudder 6 can move through the angle 61, fig. 2, e.g. by means of a motor 64, a screw 63 and a nut 62.
Vinden består av et stativ 21, fig. 2, en aksel 22 med lagring 23 og vindeplate 24 med en ytre, forholdsvis lav flens 25. Vindens innertrommel består f.eks. av tre sektorer 7, hvis stendere 71, fig. 3, festes i vindeplaten 24. De tre sektorer kan gjores sammenleggbare ved hjelp av tapper 72 og lagre 73 samt eksentrisk anbragte lagre 75 i holderne 74, som via skruer 76 og fjærer 77 bærer sektorplater 78 med pinnene 79 på hvilke tråden vikles. The wind consists of a stand 21, fig. 2, a shaft 22 with bearing 23 and winder plate 24 with an outer, relatively low flange 25. The winder's inner drum consists of e.g. of three sectors 7, whose uprights 71, fig. 3, is fixed in the winding plate 24. The three sectors can be made collapsible by means of pins 72 and bearings 73 as well as eccentrically placed bearings 75 in the holders 74, which via screws 76 and springs 77 carry sector plates 78 with the pins 79 on which the thread is wound.
Trådringene kan efter viklingen loftes opp ved hjelp av en opp-lof terplate 27, fig. 2, festet i en sentral opplofterstang 26. After winding, the wire rings can be raised by means of a lifting plate 27, fig. 2, fixed in a central lifting rod 26.
Vinden forsynes fortrinnsvis med en ovre styring 8, hvis plane plate 81 har en lagring 83 i en stempelstang 84. Den ovre styring 8 holdes fortrinnsvis i radial retning av en styreflens 82 mot stenderne 71. The wind is preferably supplied with an upper guide 8, whose flat plate 81 has a bearing 83 in a piston rod 84. The upper guide 8 is preferably held in the radial direction by a guide flange 82 against the uprights 71.
Vinden omgis av en ytre beskyttelsestrommel 28 med slisser for kjolemiddel 91 fra munnstykker 9. The wind is surrounded by an outer protective drum 28 with slits for dressing agent 91 from nozzles 9.
Ved oppvikling fores materialets 1 forende langs styredelens ytterflens 2, fig. 1, gjennom lederoret 6, som da befinner seg i sin nedre stilling, fig. 2, mot vindens bunn. Trådens forende fanges da opp mellom opplofterplaten 27, vindeplatens ytterflens 25 og de indre pinner 79. When winding, the front end of the material 1 is lined along the control part's outer flange 2, fig. 1, through the guide rudder 6, which is then in its lower position, fig. 2, towards the bottom of the wind. The front end of the wire is then caught between the winder plate 27, the outer flange 25 of the winding plate and the inner pins 79.
Hvis vindens tomgangsturtall er blitt således innstilt at inner-pinnene har noe hoyere periferihastighet enn trådens hastighet, vil tråden, når dens ende er blitt viklet opp noen vindinger i oppfangningsdelen (ved ytterflensen 25) og på grunn av friksjon mot vinden har festnet seg mot denne, bli trukket inn fra styredelens ytterflens 2. Styringsjusteringen griper da inn ved å sette i gang lederorets 6 bevegelse og justerer den innbyrdes hastighet mellom sluttvalseparet og vinden slik at materialet holdes i hensiktsmessig stilling mellom den ytre og indre flens 2 og 3 i fig. 1 i styredelen. If the idle speed of the wind has been set so that the inner pins have a somewhat higher peripheral speed than the speed of the wire, the wire, when its end has been wound up a few turns in the catch part (at the outer flange 25) and due to friction against the wind, will have stuck to it , be drawn in from the steering part's outer flange 2. The steering adjustment then intervenes by initiating the movement of the guide rod 6 and adjusts the mutual speed between the final roller pair and the wind so that the material is held in an appropriate position between the outer and inner flanges 2 and 3 in fig. 1 in the board section.
Lederorets hastighet tilpasses fortrinnsvis slik at trådvindingene legger seg tett mot hverandre. Ved 500 mm vindehoydé og 5 mm tråd fordrés 100 vindeomdreininger på et enkelt lederorslag og ved 25 mm tråd og 20 vindeomdreininger på et enkelt lederorslag. Hvis man onsker å kjole tråden under oppviklingen, tilfores kjolemiddel 91 gjennom munnstykkene 9, hvorved de ytre trådlag kjoles hvilke beskytter de innenfor liggende trådvind-inger mot ytterligere kjoling. Det tilfores så meget kjolemiddel at onsket middeltemperatur fås. Kjolemiddelet kan være væske, gass eller væske suspendert i gass. The speed of the guide rod is preferably adjusted so that the wire windings lay close to each other. With 500 mm winding height and 5 mm wire, 100 winding revolutions are required on a single conductor layer and with 25 mm wire and 20 winding revolutions on a single conductor layer. If it is desired to dress the thread during winding, dressing agent 91 is supplied through the nozzles 9, whereby the outer layers of thread are dressed, which protects the wire windings lying within against further dressing. Enough cooling agent is added to achieve the desired average temperature. The dressing agent can be liquid, gas or liquid suspended in gas.
For slike trådkvaliteter, som man ikke onsker å kjole men vil beise ved nedsenkning av ringene i et beisebad, kan man vikle med oket (eksempelvis fordoblet) hastighet for lederorets 6 bevegelse. Man får da en mere voluminos ring, som tillater at beisevæsken trenger inn i ringen. For such thread qualities, which one does not wish to dress but wants to stain by immersing the rings in a stain bath, one can wind with an increased (for example doubled) speed for the movement of the guide ring 6. You then get a more voluminous ring, which allows the pickling liquid to penetrate into the ring.
Like for trådens sluttende har nådd lederoret, senkes dette fortrinnsvis til sin nederste stilling, slik at sluttenden opptas i vindens oppfangningsdel for å hindre at den glir mot og ska-des av beskyttelsestrommelen 28. Just before the end of the thread has reached the guide rod, this is preferably lowered to its lowest position, so that the end end is taken up in the wind catchment part to prevent it from sliding towards and being damaged by the protective drum 28.
Når ringen er ferdigoppviklet brémses vinden til stillstand, den ovre styring 8 loftes opp og opplofterplaten 27 presses opp. Derved loftes ringen og sektorplatene 78 med pinner 79 likeledes inntil eksenterlagringen 72 til 74 har passert låse-stilling, hvorved fjærene 77 komprimeres. Derefter klapper sektorene 7 sammen, og ringen frigjores og kan loftes helt opp. Vindens sektorer faller derefter på ny ned av sin egen vekt og hviler mot vindeplaten 24. Ved denne utfdreise av sammenleggbar-heten fordres ingen ekstra manover ved opplofting av ringen og ved igangsetting av vinden. When the ring is fully wound, the wind is braked to a standstill, the upper guide 8 is lifted up and the lifting plate 27 is pressed up. Thereby, the ring and the sector plates 78 are likewise lifted with pins 79 until the eccentric bearings 72 to 74 have passed the locking position, whereby the springs 77 are compressed. The sectors 7 then snap together, and the ring is released and can be lifted all the way up. The sectors of the wind then fall down again by their own weight and rest against the wind plate 24. With this extension of the collapsability, no additional maneuvers are required when raising the ring and when starting the wind.
Ved oppfinnelsen oppnås at man kan få optimalt tettviklede tråd-ringer og at tråden kan gis en kontrollert kjoling som medforer jevn struktur gjennom hele trådringen ved såvel grovere som tyn-nere tråd. Dessuten kan tråden vikles opp ifolge Garret-prin-sippet ("pouring-reels") selv ved meget hoy valsehastighet. Ifolge hittil anvendte oppviklingsmetoder er hastigheten blitt begrenset til 25 å 30 m/s da sentrifugalkraften har gitt så hoyt anleggstrykk mot ytterpinnene eller den ytre trommel at trådvindingene ikke har kunnet falle til bunnen men har tilveie-bragt hulrom der og folgelig hindret utnyttelse av vindens hoyde. With the invention, it is achieved that optimally tightly wound wire rings can be obtained and that the wire can be given a controlled dressing which results in a uniform structure throughout the entire wire ring with both coarser and thinner wire. In addition, the wire can be wound up according to the Garret principle ("pouring reels") even at very high rolling speeds. According to the winding methods used until now, the speed has been limited to 25 to 30 m/s as the centrifugal force has produced such a high contact pressure against the outer pins or the outer drum that the wire windings have not been able to fall to the bottom but have created cavities there and consequently prevented the utilization of the wind's height .
Samme vinde kan således benyttes for hele dimensjonsprogrammet og også for flat tråd og andre tverrsnittsformer som ikke må vris en omdreining for hver omdreining av vinden slik som skjer ved Edenbornvindene. The same windings can thus be used for the entire dimension program and also for flat wire and other cross-sectional shapes that do not have to be twisted one revolution for each revolution of the wind, as happens with the Edenborn windings.
I og med at onsket om store ringvekter har gjort seg stadig mere gjeldende har forskjellen i avkjolingstid mellom trådvindingene midt i ringen og ved ringens ytterflate medfort storre forskjeller i struktur. Foråt oppfinnelsen med tettvikling skal kunne utnyttes i praksis fordres således at kjolingen skal kunne utfores på en så godt definert og kontrollert måte at strukturen blir jevn gjennom hele ringen. Ved mindre ringvekter og blott jern fordres ingen kjoling. As the desire for large ring weights has become increasingly relevant, the difference in cooling time between the wire windings in the middle of the ring and at the outer surface of the ring has led to larger differences in structure. Before the invention with tight winding can be used in practice, it is required that the winding can be carried out in such a well-defined and controlled manner that the structure is uniform throughout the entire ring. For smaller ring weights and bare iron, no dressing is required.
Det ligger selvsagt innenfor oppfinnelsens ramme å anordne vindene med vertikal, horisontal eller hellende aksel. It is of course within the scope of the invention to arrange the winds with a vertical, horizontal or inclined shaft.
