Description
Støpevalse for metall. Casting roller for metal.
Ved strengstøping er det kjent en metode hvorved det smeltede metall, f. eks. aluminium og aluminium-legering støpes mellom to parallelle valser, som dreies i motsatte retninger, og trer ut på utløpssiden som stivnet metall. Denne metode betegnes som støpevalsing. Da støpefor-men, som dannes av spalten mellom valsene og av veggene ved endene av valsene, er forholdsvis kort må en stor varmemengde bortføres over en meget liten strekning. Dette kan oppnås ved dusjing av valsene fra utsiden eller ved innvendig kjøling av valsene, og naturligvis kan begge disse kjølemetoder benyttes samtidig. Av drifts-messige årsaker foretrekkes imidlertid den inn-vendige kjøling av valsene. In strand casting, a method is known whereby the molten metal, e.g. aluminum and aluminum alloy are cast between two parallel rollers, which rotate in opposite directions, and emerge on the discharge side as solidified metal. This method is referred to as casting rolling. As the mould, which is formed by the gap between the rollers and by the walls at the ends of the rollers, is relatively short, a large amount of heat must be carried away over a very small distance. This can be achieved by showering the rollers from the outside or by cooling the rollers internally, and of course both of these cooling methods can be used at the same time. For operational reasons, however, internal cooling of the rollers is preferred.
Innvendig avkjølte valser ble foreslått alle-rede i 1932 av Clarence W. Hazelett, og to ut-førelsesformer er vist i U.S. patent nr. 2.058.447. Internally cooled rolls were proposed as early as 1932 by Clarence W. Hazelett, and two designs are shown in U.S. Pat. patent No. 2,058,447.
I 1950 utviklet General Motors Corp. valser for fremstilling av bånd av bly og bly-legeringer In 1950, General Motors Corp. developed rollers for the production of strips of lead and lead alloys
Disse valser er beskrevet i U.S. patent nr. 2.693.012. These rollers are described in U.S. Pat. patent No. 2,693,012.
I nyere tid (1955—56) har Jos. L. Hunter be-fattet seg med problemet vannkjøling ved støpe-valsing og utviklet to konstruksjoner beskrevet i sveitsisk patent nr. 348.241, henhv. U.S. patent nr. 2.850.776. In recent times (1955-56), Jos. L. Hunter dealt with the problem of water cooling in casting-rolling and developed two constructions described in Swiss patent no. 348,241, respectively. U.S. patent No. 2,850,776.
Endelig har det franske selskap Pechiney omkring 1957 konstruert en valse som er vist eksempelvis i det franske patent nr 1.198.006. De ovenfor omtalte valser har alle den ulem-pe at de har ujevn kjøling fra den ene ende av valsen til den annen, ved en av dem endog når kjølevannet innføres i de indre kjølekanaler under høyt trykk (f. eks. 56 ato) ved hjelp av en sterk pumpe og forbrukes i store mengder. Selv i dette siste tilfelle er det ved en valselengde på ca. 1,5 m en temperaturforskjell mellom de to ender på ca. 2°. Dette er ikke meget, men på grunn av de meget strenge arbeidsbetingelser bør en større forskjell ikke tillates, da det må ventes den samme kvalitet over hele bredden av det støpte bånd. Finally, around 1957, the French company Pechiney constructed a roller which is shown, for example, in French patent no. 1,198,006. The above-mentioned rollers all have the disadvantage that they have uneven cooling from one end of the roller to the other, with one of them even when the cooling water is introduced into the internal cooling channels under high pressure (e.g. 56 ato) using of a strong pump and is consumed in large quantities. Even in this last case, with a roll length of approx. 1.5 m, a temperature difference between the two ends of approx. 2°. This is not much, but due to the very strict working conditions, a larger difference should not be allowed, as the same quality must be expected over the entire width of the cast strip.
Støpevalsen i henhold til foreliggende opp-finnelse omfatter på kjent måte en kjerne og en mantel og er utført med skruelinjeformede kjø-lekanaler mellom kjernen og mantelen. Det sær-egne ved valsen i henhold til oppfinnelsen er at kjølekanalene har sine innløp avvekslende på den ene og den annen ende av valsen og at til-førsels- og avløps-kanalene munner ut på en og samme ende av valsekjernen. The casting roll according to the present invention comprises, in a known manner, a core and a mantle and is designed with helical cooling channels between the core and the mantle. The peculiarity of the roller according to the invention is that the cooling channels have their inlets alternately on one and the other end of the roller and that the supply and drainage channels open out at one and the same end of the roller core.
Det er altså tilførsel, henhv. avløp av kjøle-middel til, henhv. fra kjølekanalene ved begge ender av støpevalsen. Dermed oppnås at kjøle-væske strømmer i en halvpart i hver retning under valsemantelen, hvorved det oppnås konstant temperatur over hele valselengden. Dertil kom-mer at det selv ved stor valselengde (f. eks. 1,5 m) ikke kreves noen sterk pumpe for kjølevæs-ken og det klarer seg dermed med en ikke for stor væskemengde. There is therefore supply, respectively drainage of coolant to, respectively from the cooling channels at both ends of the casting roll. In this way, it is achieved that coolant flows in half in each direction under the roll jacket, whereby a constant temperature is achieved over the entire length of the roll. In addition, even with a long roller length (e.g. 1.5 m) no strong pump is required for the cooling liquid and it is thus possible to manage with a not too large amount of liquid.
Fortrinnsvis er det for tilførsel av kjølemid-del anordnet et rør midt i en aksial boring i kjernen, hvor diameteren for boringen er større enn den ytre diameter for røret og at røret ved begge ender av valsen står i forbindelse med radiale kanaler som munner ut i ringformede rom som er forbundet med kjølekanalene. Preferably, for the supply of coolant part, a pipe is arranged in the middle of an axial bore in the core, where the diameter of the bore is larger than the outer diameter of the pipe and that the pipe at both ends of the roller is in connection with radial channels that open into ring-shaped rooms that are connected to the cooling ducts.
Mellom kjerne og mantel er det anordnet flere parallelle kjølekanaler, idet hver kanal mellom de to valseender kan danne en eller flere vindinger. Det er heller ikke absolutt nødvendig at kanalene danner en hel vinding. Antallet vindinger kan videre ligge mellom 1 og 2, mellom 2 og 3 osv., men det er å foretrekke at antallet vindinger er et helt tall slik at hver kjølekanal til enhver tid utøver den samme kjølevirkning. Several parallel cooling channels are arranged between the core and mantle, as each channel between the two roller ends can form one or more windings. It is also not absolutely necessary that the channels form a complete winding. The number of windings can also be between 1 and 2, between 2 and 3, etc., but it is preferable that the number of windings is a whole number so that each cooling channel exerts the same cooling effect at all times.
Rettlinjede, akseparallelle kjølekanaler er ikke gunstige. Temperaturen på innsiden av valsemantelen er ujevn over omkretsen. Ved snodde kanaler med en eller flere vindinger blir det oppnådd at hver kjølekanal til enhver tid be-stryker det hele temperaturfelt. Straight, axis-parallel cooling channels are not favorable. The temperature on the inside of the roller jacket is uneven over the circumference. In the case of twisted ducts with one or more windings, it is achieved that each cooling duct covers the entire temperature field at all times.
På vedføyde tegning er det vist et utførel-seseksempel for valsen i henhold til oppfinnelsen. Fig. 1 viser et langsgående snitt gjennom valsen i henhold til oppfinnelsen, etter linjen B—B i fig. 2. Fig. 2 viser et tversgående snitt etter linjen A—A i fig. 1. Fig. 3 viser skjematisk temperaturforløpet for kjølemidlet gjennom valsen. The attached drawing shows an embodiment of the roller according to the invention. Fig. 1 shows a longitudinal section through the roller according to the invention, along the line B—B in fig. 2. Fig. 2 shows a transverse section along the line A—A in fig. 1. Fig. 3 schematically shows the temperature course of the coolant through the roller.
Valsen består i det vesentlige av en kjerne 11, en mantel 12, et rør 13, pakkbokser 17 og 18, og fordelerringer 23 og 24. Kjernen 11 har en aksial boring 32 som ved hjelp av røret 13 og en skulder 14 er delt i to rom 15 og 16, hvor rommet 15 over pakkboksen 17 er forbundet med vanntil-førselen og rommet 16 over pakkboksen 18 er forbundet med vannavløpet. Piler viser strøm-ningsretningen for vannet. The roller essentially consists of a core 11, a casing 12, a tube 13, stuffing boxes 17 and 18, and distributor rings 23 and 24. The core 11 has an axial bore 32 which is divided into two by means of the tube 13 and a shoulder 14 rooms 15 and 16, where the room 15 above the packing box 17 is connected to the water supply and the room 16 above the packing box 18 is connected to the water drain. Arrows show the direction of flow for the water.
Fra rommet 15 fører mot begge ender av valsen radiale forbindelseskanaler 19 og 20 til ringrom 21 og 22 i fordelerringer 23 og 24 anordnet ved endene. Disse fordelerringer 23, 24 danner med kjernen 11 hver et ytterligere ringformet rom 25, henhv. 26 som ved hjelp av boringer 27 henhv. 28 og langsgående spor 34 i en skulder 33 på røret 13 er forbundet med rommet 16. Fordelerringen 23 har kanaler 29 og 30. Om en tenker samtlige kjølekanaler 31 fortløpende nummerert, vil de med ulike nummer over for-delerringkanalene 29 være forbundet med ring-rommet 21, mens de med like nummer over for-delerringkanalene 30 er forbundet med ringrom-met 25. På tilsvarende måte har fordelerringen 24 et antall forbindelseskanaler som forbinder kjølekanalene med ringrom 22, henhv. 26. På denne måte blir valsen gjennomstrømmet av kjølevæske fra begge ender og jevnt avkjølt over hele valselengden. Snittet i fig. 1 og 2 over midtlinjen viser kjølemidlets forbindelsesveier for de kjølekanaler som har ulike nummer, mens snittet under midtlinjen viser forbindelsesveiene for de kjølekanaler som har like nummer. Radial connection channels 19 and 20 lead from space 15 towards both ends of the roller to annular spaces 21 and 22 in distributor rings 23 and 24 arranged at the ends. These distribution rings 23, 24 each form with the core 11 a further annular space 25, respectively. 26 which by means of boreholes 27 respectively. 28 and longitudinal groove 34 in a shoulder 33 of the pipe 13 are connected to the space 16. The distributor ring 23 has channels 29 and 30. If one thinks of all the cooling channels 31 consecutively numbered, those with different numbers above the distributor ring channels 29 will be connected with ring- the space 21, while those with the same number above the distributor ring channels 30 are connected to the annulus 25. In a similar way, the distributor ring 24 has a number of connection channels which connect the cooling channels to the annulus 22, respectively. 26. In this way, coolant flows through the roller from both ends and is cooled evenly over the entire length of the roller. The section in fig. 1 and 2 above the center line show the coolant connection paths for the cooling channels that have different numbers, while the section below the center line shows the connection paths for the cooling channels that have the same number.
Fig. 3 viser skjematisk temperaturforløpet for kjølemidlet ved gjennomstrømning gjennom valsen, og viser at den midlere kjøletemperatur oppnådd fra samtlige kjølekanaler 31 forblir konstant over hele valselengden. Fig. 3 schematically shows the temperature course of the coolant during flow through the roller, and shows that the average cooling temperature obtained from all cooling channels 31 remains constant over the entire length of the roller.
