As pontas de fundi\u00e7\u00e3o de alum\u00ednio s\u00e3o utilizadas como parte do mecanismo de alimenta\u00e7\u00e3o em usinas de fundi\u00e7\u00e3o e lamina\u00e7\u00e3o de alum\u00ednio e ligas de alum\u00ednio. Sua fun\u00e7\u00e3o \u00e9 fornecer alum\u00ednio l\u00edquido \u00e0 abertura entre dois rolos de fundi\u00e7\u00e3o. O rolo girat\u00f3rio funciona como um cristalizador e, simultaneamente, lamina o alum\u00ednio cristalizado.<\/p>\n

O processo de lamina\u00e7\u00e3o cont\u00ednua da usina de fundi\u00e7\u00e3o e lamina\u00e7\u00e3o cont\u00ednua consiste em introduzir continuamente metal l\u00edquido entre as aberturas de dois rolos que giram um em rela\u00e7\u00e3o ao outro, resfriados por \u00e1gua l\u00edquida, e ejetar continuamente o tarugo em bobina por meio do resfriamento e da fundi\u00e7\u00e3o cont\u00ednua.<\/p>\n

Caracter\u00edsticas do m\u00e9todo de fundi\u00e7\u00e3o e lamina\u00e7\u00e3o cont\u00ednuas com rolos duplos
\n1. Realizar a produ\u00e7\u00e3o cont\u00ednua de lingotamento e lamina\u00e7\u00e3o, eliminando os processos de lingotamento e lamina\u00e7\u00e3o a quente e reduzindo custos.
\n2. O equipamento \u00e9 simples, a \u00e1rea \u00e9 pequena, o investimento \u00e9 baixo e a velocidade de constru\u00e7\u00e3o \u00e9 alta.
\n3. Processo simples e manuten\u00e7\u00e3o pr\u00e1tica.<\/p>\n

O zona de fundi\u00e7\u00e3o-lamina\u00e7\u00e3o<\/a> refere-se \u00e0 \u00e1rea entre a linha central dos dois rolos (tamb\u00e9m chamada de linha central do rolo) e a borda dianteira do cabe\u00e7ote de fundi\u00e7\u00e3o de alum\u00ednio. O comprimento da zona de lamina\u00e7\u00e3o por fundi\u00e7\u00e3o \u00e9 determinado antes do in\u00edcio do processo. Ele \u00e9 definido pela espessura da chapa laminada por fundi\u00e7\u00e3o, pelo di\u00e2metro do rolo, pela liga, pelo desempenho do equipamento, pela for\u00e7a e pela espessura da borda das pontas da pe\u00e7a fundida de alum\u00ednio.<\/p>\n

Idealmente, a distribui\u00e7\u00e3o de calor do metal l\u00edquido que sai das pontas da m\u00e1quina de fundi\u00e7\u00e3o deve ser a mais uniforme poss\u00edvel ao longo do comprimento da ponta da m\u00e1quina. A largura das m\u00e1quinas de fundi\u00e7\u00e3o pode variar entre 0,3 m e 2,5 m.<\/p>\n

O alum\u00ednio fundido que sai das pontas de fundi\u00e7\u00e3o costuma estar mais quente na regi\u00e3o central e mais frio nas duas extremidades do ponta do rod\u00edzio<\/a>. As \u00e1reas mais frias geralmente est\u00e3o localizadas \u00e0 esquerda e \u00e0 direita da \u00e1rea central, entre a \u00e1rea central e a extremidade da ponta do moldador. Essas diferen\u00e7as de temperatura afetar\u00e3o a uniformidade do processo de fundi\u00e7\u00e3o e a qualidade da tira de metal fundido.<\/p>","protected":false},"excerpt":{"rendered":"
