DESCRIPCIONDESCRIPTION
Aleacion resistente al calor para la produccion de latas de aerosol Antecedentes de la invencionHeat resistant alloy for the production of aerosol cans Background of the invention
En la actualidad, las latas de aerosol se fabrican a partir de aluminio puro o aleaciones de aluminio. En el primer caso, se utiliza sobre todo aluminio de la serie 1000, segun la norma europea EN 573-3. Las calidades mas comunes de aluminio son EN AW 1050A, que tiene un contenido mlnimo de Al del 99,5% y EN AW 1070A, que tiene un contenido mlnimo de Al del 99,7%.Currently, aerosol cans are manufactured from pure aluminum or aluminum alloys. In the first case, mostly 1000 series aluminum is used, according to European standard EN 573-3. The most common grades of aluminum are EN AW 1050A, which has a minimum Al content of 99.5% and EN AW 1070A, which has a minimum Al content of 99.7%.
En el segundo caso, las latas de aerosol se fabrican sobre todo a partir de aleaciones de aluminio de la serie 3000, segun la norma europea EN 573-3. Las calidades mas comunes de aleacion de aluminio son EN AW 3102, que tiene un contenido de Mn de, aproximadamente, el 0,3% y EN AW 3207, que tiene un contenido de Mn de, aproximadamente, el 0,6%.In the second case, aerosol cans are manufactured primarily from 3000 series aluminum alloys, according to European standard EN 573-3. The most common grades of aluminum alloy are EN AW 3102, which has an Mn content of approximately 0.3% and EN AW 3207, which has an Mn content of approximately 0.6%.
Para la fabricacion de latas de aerosol, el aluminio y sus aleaciones se suministran en su mayor parte en forma de piezas en bruto.For the manufacture of aerosol cans, aluminum and its alloys are supplied mostly in the form of blanks.
Estas piezas en bruto son fabricadas en un proceso continuo de dos fases que comprende las siguientes etapas.These blanks are manufactured in a continuous two-phase process that includes the following stages.
a. ) Fase 1 - Fabricacion de tirasto. ) Phase 1 - Manufacturing of strips
• Fundir los lingotes en los hornos de fusion.• Melt the ingots in the melting furnaces.
• Transferir el aluminio fundido a un horno de mantenimiento.• Transfer molten aluminum to a maintenance oven.
• Colar de forma continua una tira.• Strain a strip continuously.
• Laminar la tira en caliente.• Hot strip the strip.
• Laminar la tira en frlo.• Laminate the strip in fried.
• Enrollar la tira laminada.• Roll up the laminated strip.
b. ) Fase 2 - Fabricacion de piezas en brutob. ) Phase 2 - Manufacturing of raw parts
• Desenrollar de la tira laminada.• Unwind the laminated strip.
• Perforar las piezas en bruto en una prensa de estampacion.• Drill the blanks in a printing press.
• Recocer las piezas en bruto.• Anneal the blanks.
• Enfriar las piezas en bruto.• Cool the blanks.
• Dar acabado superficial a las piezas en bruto (volteo, chorreo de arena, vibracion).• Give surface finish to the blanks (flipping, sandblasting, vibration).
• Embalar las piezas en bruto.• Pack the blanks.
El procedimiento de fabricacion de las latas de aerosol puede ser descrito tal como sigue:The manufacturing process of aerosol cans can be described as follows:
• Aplicar un lubricante a las piezas en bruto.• Apply a lubricant to the blanks.
• Extruir por impacto hacia atras.• Extrude on impact backwards.
• Prensar en plano la pared de la lata.• Press flat on the can wall.
• Cepillar la lata.• Brush the can.
• Desengrasar la lata.• Degrease the can.
• Aplicar la capa de barniz interno + curar en un horno de polimerizacion• Apply the inner varnish layer + cure in a polymerization oven
• Aplicar la capa de base + curar en horno.• Apply base coat + cure in oven.
• Aplicar las tintas decorativas + curar en horno.• Apply decorative inks + cure in oven.
• Aplicar la capa de recubrimiento + curar en horno.• Apply the coating layer + cure in the oven.
• Dar forma a las latas en la prensa de cierre.• Shape the cans in the closing press.
Los materiales descritos anteriormente, segun las normas EN AW 1050A y EN AW 1070A respectivamente, presentan niveles significativos de conformabilidad y endurecimiento por medios mecanicos, que los hacen ideales para la fabricacion de latas de aerosol en un proceso de extrusion por impacto hacia atras. Las aleaciones de aluminio EN AW 3102 y EN AW 3207 ofrecen propiedades mecanicas mejoradas (resistencia) y, por lo tanto, mejor rigidez y resistencia a la presion de las latas de aerosol finales. Sin embargo, las propiedades mecanicas de estos materiales cambian cuando las latas pasan por un horno de curado en el que tiene lugar la polimerizacion de la capa de barniz interior. Las temperaturas de curado (polimerizacion) de la capa de barniz interior oscila entre 210 y 255°C, y el proceso respectivo de curado dura unos 10 minutos. A estas temperaturas, tiene lugar el recocido parcial del cuerpo de la lata, provocando que disminuya la resistencia mecanica del mismo.The materials described above, according to standards EN AW 1050A and EN AW 1070A respectively, have significant levels of formability and hardening by mechanical means, which make them ideal for the manufacture of aerosol cans in a backward extrusion process. The aluminum alloys EN AW 3102 and EN AW 3207 offer improved mechanical properties (strength) and, therefore, better rigidity and pressure resistance of the final aerosol cans. However, the mechanical properties of these materials change when the cans pass through a curing oven in which the polymerization of the inner varnish layer takes place. The curing temperatures (polymerization) of the inner varnish layer ranges between 210 and 255 ° C, and the respective curing process takes about 10 minutes. At these temperatures, partial annealing of the can body takes place, causing its mechanical strength to decrease.
Para eliminar el anterior efecto indeseable, se deben seleccionar paredes mas gruesas de las latas de aerosol, que son necesarias para lograr las especificaciones de seguridad y tecnologicas, particularmente una suficiente resistencia a la presion de las latas. Esto causa a un aumento significativo de consumo de materiales de partida.To eliminate the above undesirable effect, thicker walls of the aerosol cans must be selected, which are necessary to achieve safety and technological specifications, particularly sufficient pressure resistance of the cans. This causes a significant increase in consumption of starting materials.

Descripcion breve de los dibujosBrief description of the drawings
La presente invencion se explicara adicionalmente con referencia a los dibujos adjuntos, en los que la figura 1 muestra la dependencia con la temperatura de las resistencias de las nuevas aleaciones en comparacion con las aleaciones estandar mediante una representacion grafica.The present invention will be further explained with reference to the accompanying drawings, in which Figure 1 shows the temperature dependence of the resistances of the new alloys compared to the standard alloys by means of a graphical representation.
El objeto de la presente invencion es una aleacion a base de aluminio nueva, modificada y resistente al calor, para eliminar el efecto de debilitamiento del material de las latas que pasan a traves de horno de curado. De este modo, se logra la mejora deseada de las propiedades mecanicas de las latas de aerosol en comparacion con los materiales (utilizados convencionalmente) estandar, junto con la reduccion del espesor de la pared y el aumento de la resistencia a la presion de la misma. Particularmente, el efecto favorable anterior se consigue mediante la adicion de un aditivo antirrecristalizacion formado por Zr (circonio) con el fin de modificar las composiciones de aluminio y sus aleaciones: EN AW 1050A, EN AW 3102, EN AW 3207.The object of the present invention is a new, modified and heat-resistant aluminum-based alloy to eliminate the weakening effect of the material of the cans that pass through a curing oven. In this way, the desired improvement of the mechanical properties of aerosol cans is achieved in comparison with standard (conventionally used) materials, together with the reduction in wall thickness and the increase in pressure resistance thereof. . In particular, the above favorable effect is achieved by the addition of an antirecrystallization additive formed by Zr (zirconium) in order to modify the aluminum compositions and their alloys: EN AW 1050A, EN AW 3102, EN AW 3207.
Las composiciones qulmicas de las aleaciones utilizadas de forma habitual, no modificadas, tienen los siguientes valores llmite segun la norma EN 573-3, en porcentaje en peso:The chemical compositions of the alloys commonly used, unmodified, have the following values according to EN 573-3, in percentage by weight:
EN AW 1050AIN AW 1050A
Si < 0,25; Fe < 0,40; Cu < 0,05; Mn < 0,05; Mg < 0,05; Zn < 0,07; Ti < 0,05; Al 99,5 min.,If <0.25; Fe <0.40; Cu <0.05; Mn <0.05; Mg <0.05; Zn <0.07; Ti <0.05; At 99.5 min.,

Si < 0,40; Fe < 0,70; Cu < 0,10; Mn 0,05-0,40; Zn < 0,30; Ti < 0,10; resto Al EN AW 3207If <0.40; Fe <0.70; Cu <0.10; Mn 0.05-0.40; Zn <0.30; Ti <0.10; rest Al EN AW 3207
Si < 0,30; Fe < 0,45; Cu < 0,10; Mn 0,40-0,80; Mg < 0,10; Zn < 0,10; resto AlIf <0.30; Fe <0.45; Cu <0.10; Mn 0.40-0.80; Mg <0.10; Zn <0.10; Al rest
La aleacion, segun la presente invencion, tiene una composition qulmica nueva con Zr anadido, oscilando la proportion del nuevo constituyente entre el 0,10 y el 0,15% en peso. La adicion de Zr da lugar a aleaciones completamente nuevas que no se pueden clasificar en las clases existentes segun la norma EN 573-3. Por lo tanto, las nuevas aleaciones se designaran a continuation como aleaciones MC, es decir, MC1 (EN AW 1050A + Zr). La composicion de la nueva aleacion (en porcentaje en peso) es la siguiente:The alloy, according to the present invention, has a new chemical composition with Zr added, the proportion of the new constituent ranging between 0.10 and 0.15% by weight. The addition of Zr results in completely new alloys that cannot be classified into existing classes according to EN 573-3. Therefore, the new alloys will then be designated as MC alloys, that is, MC1 (EN AW 1050A + Zr). The composition of the new alloy (in percentage by weight) is as follows:
Aleacion MC1MC1 alloy
Si < 0,25; Fe < 0,40; Cu < 0,05; Mn < 0,05; Mg < 0,05; Zn < 0,07; Ti < 0,05; Zr = 0,10-0,15; resto Al; (suma de todos los elementos secundarios < 0,10)If <0.25; Fe <0.40; Cu <0.05; Mn <0.05; Mg <0.05; Zn <0.07; Ti <0.05; Zr = 0.10-0.15; Al rest; (sum of all secondary elements <0.10)
Para verificar el efecto antirrecristalizacion durante el proceso de produccion de las latas de aerosol, se compararon las nuevas aleaciones con los materiales conocidos y utilizados de forma habitual. El resultado se representa graficamente en la figura 1 en el que el primer material estandar, segun la norma EN AW 1050A, en el presente documento especlficamente designado como la aleacion A5, se compara con la nueva aleacion MC1_A y el segundo material estandar, segun la norma EN AW 3102, en el presente documento especlficamente denominado como aleacion A3Mn, se compara con otra nueva aleacion MC3_A que contiene el constituyente Zr antirrecristalizacion anadido, que no esta dentro del ambito de la presente invencion. Las latas, que se realizaron a partir de estos materiales en las mismas condiciones tecnologicas, tenlan especificaciones de pared identicas.To verify the antirecrystallization effect during the production process of aerosol cans, the new alloys were compared with known and commonly used materials. The result is represented graphically in Figure 1 in which the first standard material, according to EN AW 1050A, in this document specifically designated as the A5 alloy, is compared with the new MC1_A alloy and the second standard material, according to the Standard EN AW 3102, in this document specifically referred to as A3Mn alloy, is compared to another new MC3_A alloy containing the added Zr anti-crystallization constituent, which is not within the scope of the present invention. The cans, which were made from these materials in the same technological conditions, had identical wall specifications.

La tabla 1 muestra las propiedades mecanicas de las latas producidas a partir de los materiales anteriores. Durante la comparacion, se evaluaron los valores de resistencia a la traccion (Rm) de las latas medidos antes y despues del horno de curado, en que se polimerizo la capa de barniz interior. Ademas, se midio la dureza (HB) de los productos semielaborados de entrada (piezas en bruto).Table 1 shows the mechanical properties of cans produced from the above materials.

Los resultados enumerados en la tabla 1 muestran claramente que los materiales estandar pierden su resistencia a la traccion cuando estan sometidos a la temperatura de 255°C en el horno, disminuyendo la resistencia el 17,7% para el aluminio A5 y el 16,3% para la aleacion A3Mn. En contraste con esto, la perdida de resistencia de las aleaciones que contienen Zr es significativamente menor, es decir, solo el 2,2% para la aleacion de MC1_A y el 2,3% para la aleacion MC3_A. En varios casos, se observo incluso un aumento de la resistencia a la traccion de las nuevas aleaciones despues de que hubieran pasado por el horno de curado.The results listed in Table 1 clearly show that standard materials lose their tensile strength when subjected to the temperature of 255 ° C in the oven, reducing resistance 17.7% for A5 aluminum and 16.3 % for the A3Mn alloy. In contrast to this, the loss of resistance of Zr-containing alloys is significantly lower, that is, only 2.2% for the MC1_A alloy and 2.3% for the MC3_A alloy. In several cases, there was even an increase in the tensile strength of the new alloys after they had passed through the curing oven.
La comparacion del aluminio A5 con la aleacion de MC1_A muestra que el valor de resistencia a la traccion de esta ultima aleacion fue 32,1 MPa mas elevado despues del paso por el horno de polimerizacion a la temperatura de 255°C.The comparison of the A5 aluminum with the MC1_A alloy shows that the tensile strength value of the latter alloy was 32.1 MPa higher after passing through the polymerization furnace at the temperature of 255 ° C.
La comparacion de las aleaciones de aluminio A3Mn y MC3_A muestra que el valor de resistencia de esta ultima aleacion fue 27,1 MPa mas elevado despues del paso por el horno de polimerizacion a la temperatura de 255°C.The comparison of the A3Mn and MC3_A aluminum alloys shows that the resistance value of the latter alloy was 27.1 MPa higher after passing through the polymerization furnace at the temperature of 255 ° C.
Tambien resulta ser ventajoso el hecho de que, aunque la aleacion MC1_A que contiene el componente Zr anadido tiene su resistencia a la traccion, despues de la extrusion hacia atras, 9,7 MPa menor en comparacion con la aleacion de A3Mn, el paso de la aleacion MC1_A a traves del horno de polimerizacion a temperaturas por encima de 226°C provoca que la resistencia de esta aleacion supere la resistencia de la aleacion de A3Mn, a pesar de que la aleacion de MC1_A no contiene manganeso.Also advantageous is the fact that, although the MC1_A alloy containing the added Zr component has its tensile strength, after extrusion backwards, 9.7 MPa lower compared to the A3Mn alloy, the passage of the MC1_A alloy through the polymerization furnace at temperatures above 226 ° C causes the resistance of this alloy to exceed the resistance of the A3Mn alloy, although the MC1_A alloy does not contain manganese.
Entre las ventajas principales de las nuevas aleaciones MC1, MC3 (que no esta dentro del alcance de la presente invencion) y (que no esta dentro del alcance de la presente invencion) se incluyen particularmente:Among the main advantages of the new MC1, MC3 alloys (which is not within the scope of the present invention) and (which is not within the scope of the present invention) are particularly included:
a. ) Debido a la adicion de Zr, las aleaciones MC1, MC3 y MC4 contienen una dispersion fina de AbZr.to. ) Due to the addition of Zr, the MC1, MC3 and MC4 alloys contain a fine dispersion of AbZr.
b. ) La presencia de manganeso en las aleaciones MC3 y MC4 da como resultado ademas un aumento de la resistencia de estas aleaciones despues de someterse a un proceso de conformacion, esto es debido a la formacion de partlculas de Al6Mn, Al6(FeMn) y a-AI(Mn,Fe)Si.b. ) The presence of manganese in MC3 and MC4 alloys also results in an increase in the strength of these alloys after undergoing a forming process, this is due to the formation of Al6Mn, Al6 (FeMn) and a- particles. AI (Mn, Fe) Yes.
c. ) Las partlculas anteriores quedan atrapadas en los llmites subgranulares, evitando que se produzca de este modo cualquier recuperacion o formacion de nucleos de recristalizacion o crecimiento de granos recristalizados (aumento de la resistencia a la recristalizacion).C. ) The previous particles are trapped in the subgranular boundaries, thus preventing any recovery or formation of recrystallization nuclei or growth of recrystallized grains (increase in resistance to recrystallization).
