La aleaci\u00f3n de aluminio y estroncio act\u00faa como fundido en la aleaci\u00f3n. Se puede decir que es un modificador, refinador y aditivo para las aleaciones de aluminio, capaz de alterar la composici\u00f3n de la aleaci\u00f3n y modificar sus propiedades de aplicaci\u00f3n.<\/p>\n

Contenido de la aleaci\u00f3n de Al-Sr<\/h2>\n

Al-Sr5: contenido 4,0-6,01 TP3TSr<\/p>\n

Contenido de impurezas: hierro 0,16%; silicio 0,20%<\/p>\n

Al-Sr10: contenido de 9,0-11,0 Sr<\/p>\n

Contenido de impurezas: hierro 0,20%; silicio 0,20%<\/p>\n

\u00bfCu\u00e1l es la funci\u00f3n de la aleaci\u00f3n de aluminio y estroncio?<\/h2>\n

Aleaciones de aluminio y estroncio<\/a> Puede refinar eficazmente el silicio eut\u00e9ctico y el silicio primario de la aleaci\u00f3n, mejorando as\u00ed sus propiedades mec\u00e1nicas. Su modificaci\u00f3n tiene un buen efecto a largo plazo, y la estabilidad de la refundici\u00f3n y la resistencia a la degradaci\u00f3n son mejores. La cantidad de estroncio a\u00f1adida se controla generalmente entre 0,02 y 0,041 TP3T. Por ejemplo, el contenido de estroncio del agente de escoria en la aleaci\u00f3n de aluminio-estroncio es de 10%, y la proporci\u00f3n de adici\u00f3n se sit\u00faa entre 0,2 y 0,4%, lo que garantiza eficazmente el efecto de modificaci\u00f3n. Por lo general, la aleaci\u00f3n de Al-Sr se a\u00f1ade a la aleaci\u00f3n, y la aleaci\u00f3n de aluminio y estroncio suele precalentarse a 200-300 grados; a continuaci\u00f3n, se a\u00f1aden los dem\u00e1s componentes correspondientes en la proporci\u00f3n adecuada tras retirar los dem\u00e1s componentes correspondientes.<\/p>\n

El estroncio (Sr) es un modificador de acci\u00f3n prolongada; su efecto modificador es equivalente al del sodio y no presenta las desventajas de la modificaci\u00f3n con sodio, por lo que se trata de un modificador prometedor. El Reino Unido, los Pa\u00edses Bajos y otros pa\u00edses comenzaron a promover la aplicaci\u00f3n de m\u00e9todos de metamorfismo con estroncio (Sr) a principios de la d\u00e9cada de 1980. En la actualidad, se han realizado numerosas investigaciones sobre la degradaci\u00f3n del estroncio tanto a nivel nacional como internacional. El uso del estroncio (Sr) en sustituci\u00f3n del sodio o de las sales de sodio tambi\u00e9n est\u00e1 aumentando en China.<\/p>\n

\"Aleaci\u00f3n<\/p>\n

Ventajas del modificador de estroncio<\/h2>\n
    \n
  1. Buen efecto modificador y un largo periodo de validez.<\/li>\n
  2. El proceso de modificaci\u00f3n no genera humo, no es t\u00f3xico, no contamina el medio ambiente, no corroe los equipos ni las herramientas, no es perjudicial para la salud y es f\u00e1cil de llevar a cabo.<\/li>\n
  3. Es f\u00e1cil conseguir propiedades mec\u00e1nicas satisfactorias.<\/li>\n
  4. El efecto de la refundici\u00f3n y la modificaci\u00f3n es considerable.<\/li>\n
  5. El rendimiento de la fundici\u00f3n es elevado y el beneficio econ\u00f3mico global es notable.<\/li>\n<\/ol>","protected":false},"excerpt":{"rendered":"
