Description
Nærværende oppfinnelse vedrorer forbedrede kornforfiningsmidler som inneholder titan-metall. The present invention relates to improved grain refining agents containing titanium metal.
Det "har tidligere blitt foreslå-tt å anvende metallisk titan som en kornforfiner for aluminium og aluminiumlegeringer. imidlertid lider titan-metall og.kjente kornforfiningssammen-setninger, som inneholder titanmetall, av et antall ulemper, It has previously been proposed to use metallic titanium as a grain refiner for aluminum and aluminum alloys. However, titanium metal and known grain refining compositions containing titanium metal suffer from a number of disadvantages,
Titanmetall opploses for langsomt i smeltet aluminium ved normale industrielle driftstemperaturer, og som resultat herav blir den tilgjengelige tiden mellom tilsetningen av. den kornforfinende tilsatsen og stoping av opplosningen av titan ufullstendig. Man har funnet .at -opplesningen og folgeli-g utbyttet av titan i det stopte aluminiumet påvirkes av til-standen til overflaten av det smeltede aluminiumet, nærvær av dross eller flussmidler forårsaker at en eksoterm reaksjon finner sted og at titanutbyttet reduseres. Noen forbedring kan fås hvis titan-metallet, som inneholder kornforfinende-tilsats, blir nedsenket og holdt under det smeltede aluminium-ets overflate. Imidlertid innebærer nedsenkningsoperasjonen et ytterligere arbeidstrinn for stoperiarbeideren, og det består en fare for at aluminiumet kan bli forurenset av ned-senknings ver ktoyet . Titanium metal dissolves too slowly in molten aluminum at normal industrial operating temperatures, and as a result the available time between additions is reduced. the grain refining additive and stopping the dissolution of titanium incompletely. It has been found that the reading and consequently the yield of titanium in the stopped aluminum is affected by the condition of the surface of the molten aluminum, the presence of dross or fluxes causing an exothermic reaction to take place and the titanium yield to be reduced. Some improvement can be obtained if the titanium metal, containing grain refining additive, is immersed and held below the surface of the molten aluminum. However, the immersion operation involves a further work step for the stopper worker, and there is a danger that the aluminum may be contaminated by the immersion tool.
Man har nå funnet at titanmetall kan anvendes effektivt som It has now been found that titanium metal can be used effectively as
en kornforfinende tilsats for aluminium hvis titan anvendes i form av partikler som er mindre, enn 400 um og komprimert sammen med et komplekst salt for derved å gi en sammensetning med en densitet slik at sammensetningen, når denne tilsettes til det smeltede, aluminiumet, vil synke under overflaten til det smeltede aluminiumet. a grain refining additive for aluminum whose titanium is used in the form of particles smaller than 400 µm and compacted together with a complex salt to thereby provide a composition with a density such that, when added to the molten aluminum, the composition will sink below the surface of the molten aluminum.
Ifolge nærværende oppfinnelse har man fremskaffet et According to the present invention, a
middel, for kornforfining av aluminium eller aluminiumlegeringer, og midlet bes-tår av: 1) 15 - 85 vekts-% metallisk titan og/eller titanlegering som inneholder ikke mindre enn 85% titan; 2) 2,5-70 vekts-% av ett eller flere salter av natrium-borf luorid,_ kaliumborf luorid, natriumtitanfluorid, kaliumtitanfluorid, natriumzirkonfluorid og kalium-zirkonfluorid; og agent, for grain refinement of aluminum or aluminum alloys, and the agent consists of: 1) 15 - 85% by weight metallic titanium and/or titanium alloy containing not less than 85% titanium; 2) 2.5-70% by weight of one or more salts of sodium boron fluoride, potassium boron fluoride, sodium titanium fluoride, potassium titanium fluoride, sodium zirconium fluoride and potassium zirconium fluoride; and
3) O - 46 vekts-% av et metall som har en densitet som 3) O - 46% by weight of a metal which has a density which
er storre enn 4,5 g/cm 3 valgt blandt mangan, kopper, . jern, ferromangan og nikkel-kromlegering. are greater than 4.5 g/cm 3 chosen from manganese, copper, . iron, ferromanganese and nickel-chromium alloy.
Innholdet av sistnevnte metall i 3) skal ikke overstige innholdet av titanet eller titanlegeringen, og innholdet av komponent 2) bor minst være 12% av innholdet av nevnte titan eller titanlegering. Nevnte titan og/eller titanlegering skal. ha en partikkelstorrelse som ikke er storre enn 4oo (im og midlet skal ha en densitet pa o minst 2,4- g/cm 3. • The content of the latter metal in 3) must not exceed the content of the titanium or titanium alloy, and the content of component 2) must be at least 12% of the content of said titanium or titanium alloy. Said titanium and/or titanium alloy shall. have a particle size that is not larger than 4oo (im) and the agent must have a density of at least 2.4 g/cm 3. •
Det aktuelle metallet og den anvendte mengden i kornforfinings-midlet vil bli slik valgt at den nodvendige spesifika- The metal in question and the amount used in the grain refining agent will be chosen in such a way that the necessary specifica-
sjon for det stopte aluminiumet eller aluminiumslegeringen oppfylles. tion for the stopped aluminum or aluminum alloy is met.
Flussmidler, såsom alkalimetall- eller jordalkalimetall-halogenider kan inkorporeres i korn--forfinings-.midlet. Karbonater kan også anvendes. Eksempler på egnede flussmidler er natrium-klorid, kaliumklorid, natriumfluorid, kaliumfluorid, natrium-aluminiumfluorid og kaliumaluminiumfluorid. Når foran nevnte flussmidler anvendes vil innholdet av flussmidlet normalt ikke være storre enn 53 vekts-%. Fluxes such as alkali metal or alkaline earth metal halides can be incorporated into the grain refining agent. Carbonates can also be used. Examples of suitable fluxes are sodium chloride, potassium chloride, sodium fluoride, potassium fluoride, sodium aluminum fluoride and potassium aluminum fluoride. When the fluxes mentioned above are used, the content of the flux will normally not be greater than 53% by weight.
Kronforfinings-midlet kan fremstilles ved hjelp av The crown refinement agent can be produced using
en hvilken som helst kjent metode, som omfatter blanding av komponentene og derefter komprimering for således å fremstille en sammenhengende masse med onsket densitet. Ingrediensene blandes f.eks. i en båndblad-blander med en tonns kapasitet, hvorefter tabletter presses i en 70- tonn BIPEL-presse. any known method, which comprises mixing the components and then compacting so as to produce a cohesive mass of the desired density. The ingredients are mixed e.g. in a ribbon mixer with a capacity of one tonne, after which tablets are pressed in a 70-tonne BIPEL press.
Hvis onsket kan noe annet materiale inkorporeres i kornforfinings-midlet som hjelpemiddel ved produksjonen av en sammenhengende masse, eller massen kan forvarmes. If desired, some other material can be incorporated into the grain refining agent as an aid in the production of a cohesive mass, or the mass can be preheated.
Når den tilsatte mengden anvendes for behandling av smeltet aluminium eller smeltede aluminiumlegeringer, så bor vekst-forholdet, være 0,005 til 0,2 vekts-% Ti. When the added amount is used for the treatment of molten aluminum or molten aluminum alloys, the growth ratio should be 0.005 to 0.2 wt% Ti.
Polgende eksempler skal tjene-til å illustrere oppfinnelsen. The following examples shall serve to illustrate the invention.
I samtlige eksempler er folgende forsøksprosedyre anvendt: In all examples, the following test procedure is used:
Kornforfinings-midlet, som skal undersokes, ble The grain refinement agent, to be investigated, was
tilvirket ved å blande ingrediensene sammen- i en planetarisk virkende blander, hvorefter det av deler av blandingen ble fremstilt tabletter i en hydraulisk tablett-tilvirknings- produced by mixing the ingredients together in a planetary-acting mixer, after which parts of the mixture were made into tablets in a hydraulic tablet-making machine

hadde en vekt på ca. 150 g, og deres densitet ble derefter bestemt på vanlig måte. had a weight of approx. 150 g, and their density was then determined in the usual way.
Kornforfinings-midlet. ble undersokt med hensyn til virkningsmåten ved å tilsette midlet til smeltet "LMO"-aluminium (99,8% Al), og da i en mengde på 0,02 vekts-% titan. "LMO"-aluminiumet ble holdt ved 730°C. The grain refiner. was investigated for mode of action by adding the agent to molten "LMO" aluminum (99.8% Al), and then in an amount of 0.02 wt% titanium. The "LMO" aluminum was held at 730°C.
Prover.ble uttatt og støpt i forvarmede silimanitt-proveformer 2 minutter for, 10 minutter efter og 40 minutter efter tilsetningen av midlet. Samples were taken and cast into preheated sillimanite sample molds 2 minutes before, 10 minutes after and 40 minutes after the addition of the agent.
♦ Stopegodsene som var. 2,5 cm i diameter -og 7,5 cm hoye, ble gjennomskåret langsefter og så 2,5 cm fra basisen. Den avskårede overflaten av basisen ble derefter polert med 600 mikron silisiumkarbid-papir ved anvendelse av vann som smøre-middel, og derefter etset under anvendelse av en blandet syre-losni.ng. 1 samtlige tilfeller var den øyensynlige cellestorrelsen efter etsningen visuelt meget mindre for provene som ble stopt efter tilsetningen av kornforfinings-midlet, men det var ingen vesentlig forskjell mellom proven som ble tatt IO minutter og proven som ble tatt 40 minutter efter tilsetningen. Følgelig ble celle-storrelse-bestemninger utfort bare på provene som ble tatt for tilsetningen og på provene som ble tatt 40 minutter efter tilsetningen. ♦ The stop goods that were 2.5 cm in diameter - and 7.5 cm high, was cut through lengthwise and then 2.5 cm from the base. The cut surface of the base was then polished with 600 micron silicon carbide paper using water as a lubricant, and then etched using a mixed acid solution. In all cases, the apparent cell size after etching was visually much smaller for the samples that were stopped after the addition of the grain refiner, but there was no significant difference between the sample taken 10 minutes and the sample taken 40 minutes after the addition. Consequently, cell size determinations were performed only on the samples taken before the addition and on the samples taken 40 minutes after the addition.
