Abstract

Patente de Invenção: <B>"PROCESSO PARA A PRODUçãO DE FOLHA DE LIGA DE ALUMìNIO QUE PODE SER TRATADA A QUENTE"<D>. Um processo para a produção de artigos em folha de alumínio feitos de liga de alumínio da série 6000 ou 2000 adequada para a fabricação de peças de automóveis. O processo compreende fundição direta na lingoteria da liga para produzir um lingote fundido, fresagem do lingote fundido para formar um lingote escarfado, homogeneização do lingote escarfado a uma temperatura entre 480 e 580 °C durante menos de 48 horas para formar um lingote homogeneizado, laminação a quente do lingote homogeneizado até um calibre intermediário para formar um artigo de espessura intermediária e laminação a frio do artigo de espessura intermediária até o calibre final, em que a laminação a frio reduz a espessura do artigo em folha intermediário por uma quantidade na faixa de 15 até 40% do calibre final, Por limitação da quantidade de redução provocada pela laminação a frio, podem ser reduzidos ou eliminados os efeitos exibidos no produto final em têmpera T4 (normalmente após <B>solutionizing<D> e pré-envelhecimento). De fato, a etapa de laminação a frio pode ser inteiramente eliminada, se for conseguida uma redução adequada da espessura da folha apenas por laminação a quente.Invention Patent: <B> "PROCESS FOR THE PRODUCTION OF ALUMINUM ALLOY SHEET THAT CAN BE TREATED HOT" <D>. A process for the production of aluminum foil articles made from 6000 or 2000 series aluminum alloy suitable for the manufacture of auto parts. The process comprises direct casting into the alloy ingot to produce a molten ingot, milling the molten ingot to form a scarlet ingot, homogenizing the scarlet ingot at a temperature between 480 and 580 ° C for less than 48 hours to form a homogenized ingot, lamination hot from the homogenized ingot to an intermediate gauge to form an article of intermediate thickness and cold rolling of the article of intermediate thickness until the final gauge, where cold rolling reduces the thickness of the intermediate sheet article by an amount in the range of 15 to 40% of the final caliber, By limiting the amount of reduction caused by cold rolling, the effects shown in the final product in T4 tempering can be reduced or eliminated (usually after <B> solutionizing <D> and pre-aging). In fact, the cold lamination step can be eliminated entirely, if an adequate reduction in the thickness of the sheet is achieved only by hot lamination.
