Description
Som kjent har mykglødingsbetingeIsene stor innvirkning på mykningstilstanden for flytpressede/ boksformede legemer. Når disse blir brennlakkert, går en del av fasthetsøkningen tapt under lagringen. As is well known, the soft annealing conditions have a major impact on the softening state of flow-pressed/box-shaped bodies. When these are varnished, part of the increase in strength is lost during storage.
På denne bakgrunn er det et formål med oppfinnelsen On this background, there is an object of the invention
å minske fasthetsreduksjonen ved brennlakkering av slike boksformede legemer, og ved hjelp av økede fasthetsverdier for slike legemer å oppnå en betydelig metallinnsparing. to reduce the reduction in strength by fire lacquering of such box-shaped bodies, and by means of increased strength values for such bodies to achieve a significant metal saving.
Løsningen av denne oppgaven fører til erkjennelsen av The solution of this task leads to the recognition of
at den fasthet som skyldes kalddeformasjon, det vil si ekstrudering, skal minske minst mulig etter innbrenning av lakk, og at deformeringsmotstanden ved hjelp av rekrystallisasjonshemmende tilsetninger ikke øker. that the firmness due to cold deformation, i.e. extrusion, should decrease as little as possible after burning in the varnish, and that the resistance to deformation with the help of recrystallization-inhibiting additives does not increase.
I henhold til oppfinnelsen oppnås dette ved at det anvendes renaluminium med 0,05 til 0,1 vekt% silisium og 0,1 According to the invention, this is achieved by using pure aluminum with 0.05 to 0.1% by weight of silicon and 0.1
til 0,25 vektas jern, og hvor renaluminiumet er tilsatt i det minste to av de rekrystallisasjonshemmende og i aluminium peritektisk forholdende elementer krom, titan og zirkonium i mengder på 0,02 til 0,3 vekt% av hvert element, to 0.25% by weight of iron, and where the pure aluminum has been added at least two of the recrystallization-inhibiting and in aluminum peritectic elements chromium, titanium and zirconium in amounts of 0.02 to 0.3% by weight of each element,
for fremstilling av flytpressede og brennlakkerte, boksformede legemer. for the production of flow-pressed and fire-varnished, box-shaped bodies.
Disse små tilsatsmengder av rekrystallisasjonshemmende elementer bevirker en minskning av fasthetsreduksjonen for det herdede, boksformede element ved lakkinnbrenning, men elementene må være slik dosert at de ikke forstyrrer ekstruderingsforløpet. These small addition amounts of recrystallization-inhibiting elements cause a decrease in the strength reduction for the hardened, box-shaped element during varnish firing, but the elements must be dosed in such a way that they do not interfere with the extrusion process.
Såvel utstøpingen på dreieskive, varm- og kaldvalsing samt vanlig gløding av rondeller kan bibeh'oldes, slik at investeringskostnader unngås. Det er dessuten mulig å gjennomføre fremstillingen med materialbiter av ekstruderte bånd. Casting on a turntable, hot and cold rolling as well as normal annealing of rondels can also be maintained, so that investment costs are avoided. It is also possible to carry out the production with pieces of material from extruded strips.
Det har vist seg særdeles gunstig å tilsette krom og/eller titan og/eller zirkonium i mengder på mindre enn 0,2 vekt%. It has proven particularly beneficial to add chromium and/or titanium and/or zirconium in quantities of less than 0.2% by weight.
I henhold til et ytterligere trekk ved oppfinnelsen skal tilsetningen av titan og zirkonium tilsammen utgjøre 0,2 vekt%. According to a further feature of the invention, the addition of titanium and zirconium shall together amount to 0.2% by weight.
Ved forsøk ble renaluminium-biter fra et varmvalset bånd When tested, pieces of pure aluminum were obtained from a hot-rolled strip
og renaluminium-biter med tilsats av 0,1 vekt% titan og zirkonium sammenlignet.Boksformede legemer utsatt for en varmebehandling som tilsvarende brennlakkering og fremstilt av disse to varianter viser at tilsetning av titan og zirkonium bevirker en omtrent 20% høyere strekkfasthet i forhold til boksformede legemer fremstilt av renaluminium-biter uten disse tilsetninger. Materialinnsparingen for de boksformede legemer utgjør omtrent 8%, på grunn av fasthetsøkningen. and renaluminium pieces with the addition of 0.1% by weight of titanium and zirconium compared. Box-shaped bodies subjected to a heat treatment equivalent to burnishing and produced from these two variants show that the addition of titanium and zirconium causes an approximately 20% higher tensile strength compared to box-shaped bodies made from pure aluminum pieces without these additions. The material saving for the box-shaped bodies amounts to approximately 8%, due to the increase in firmness.
Yttterligere fordeler, trekk og detaljer ved oppfinnelsen fremgår av den følgende tabell og vedføyde tegning, som viser forsøksresultater fra fire forskjellige forsøk. Further advantages, features and details of the invention appear from the following table and attached drawing, which shows test results from four different trials.
Det ble fremstilt biter av plater med tykkelse på omtrent Pieces of plates with a thickness of approx
7 mm og av forskjellige sammensetninger, og bitene ble etter en oppvarmingstid på ca. 40 minutter i en luftvarme-ovn glødet omtrent 10 sekunder ved 490°c.Materialsammen-setningen fremgår av den følgende tabell. 7 mm and of different compositions, and the pieces were after a heating time of approx. 40 minutes in an air heating furnace, annealed for approximately 10 seconds at 490°c. The material composition appears in the following table.
Deretter ble bitene for å simulere en ekstruderingspro-sess kaldvalset til 0,5 mm og i stedet for brenn- Then, to simulate an extrusion process, the pieces were cold rolled to 0.5 mm and instead of burning
lakkering varmet i et saltbad ved 260°C og bråkjølt i vann. varnishing heated in a salt bath at 260°C and quenched in water.
I det koordinatsystem som er vist på tegningen er langs In the coordinate system shown in the drawing is along
den horisontale akse angitt varmetiden i minutter for den simulerte brennlakkering, og langs den vertikale akse er angitt strekkfastheten i kp/mm^. the horizontal axis indicates the heating time in minutes for the simulated fire varnishing, and along the vertical axis the tensile strength is indicated in kp/mm^.
Sammenlignes kurvene for materialsammensetningene I, II, III og IV, der material nr, II, III og IV ligger innen rammen av detsom anvendes i henhold til den foreliggende opp-finnelse fremgår det tydelig hvor meget høyere strekkfastheten for de materialer er som inneholder i det minste to av elementene krom, titan og zirkonium. Forskjellen i strekkfasthet etter en glødetid på 8 minutter er således omtrent 4 kp/mm<2>. If the curves for the material compositions I, II, III and IV are compared, where material no. at least two of the elements chromium, titanium and zirconium. The difference in tensile strength after an annealing time of 8 minutes is thus approximately 4 kp/mm<2>.
Fasthetsverdiene for de boksformede legemer ligger noe høyere enn de viste fasthetsverdier for platene, og de tilsvarende kurver for de bokslignende legemer vil altså ligge forskjøvet parallelt oppover i forhold til de viste. The strength values for the box-shaped bodies are somewhat higher than the shown strength values for the plates, and the corresponding curves for the box-like bodies will therefore be shifted parallel upwards in relation to those shown.
