A posi\u00e7\u00e3o do orif\u00edcio fixo da comporta do canal de distribui\u00e7\u00e3o n\u00e3o deve ficar abaixo do limite inferior da altura do alum\u00ednio fundido no canal de distribui\u00e7\u00e3o, a fim de evitar que o alum\u00ednio fundido derreta o suporte met\u00e1lico e afete a qualidade do alum\u00ednio fundido. A comporta do canal de distribui\u00e7\u00e3o tamb\u00e9m \u00e9 chamada de barragem do canal de distribui\u00e7\u00e3o, placa defletora do canal de distribui\u00e7\u00e3o, canal de transfer\u00eancia de metal<\/a>. A placa de prote\u00e7\u00e3o dianteira e a placa de prote\u00e7\u00e3o traseira s\u00e3o placas de a\u00e7o com espessura de 5 mm a 10 mm, soldadas ao perfil em U da placa de fundo do cilindro. As aberturas dos furos de fixa\u00e7\u00e3o da placa de prote\u00e7\u00e3o dianteira e da placa de prote\u00e7\u00e3o traseira s\u00e3o iguais \u00e0s aberturas dos furos de fixa\u00e7\u00e3o da barragem da calha de fluxo, e as posi\u00e7\u00f5es correspondem umas \u00e0s outras.<\/p>\n

A chapa defletora do canal, a chapa de prote\u00e7\u00e3o traseira e a chapa de prote\u00e7\u00e3o dianteira s\u00e3o conectadas por parafusos atrav\u00e9s dos orif\u00edcios de fixa\u00e7\u00e3o e dos orif\u00edcios de montagem. Trata-se de encaixes com folga. Elas n\u00e3o devem ser instaladas com muita for\u00e7a, deixando espa\u00e7o para movimento, a fim de evitar que a chapa defletora do canal seja esmagada quando for abaixada.

Caracter\u00edsticas do Launder Gate<\/strong><\/p>\n

    \n
  1. O dispositivo tem como finalidade controlar a altura da posi\u00e7\u00e3o do alum\u00ednio fundido no canal de vazamento antes da fundi\u00e7\u00e3o e garante que a altura da posi\u00e7\u00e3o do alum\u00ednio fundido atenda aos par\u00e2metros t\u00e9cnicos da fundi\u00e7\u00e3o.<\/li>\n
  2. A altura do defletor do canal \u00e9 reduzida, e uma placa de prote\u00e7\u00e3o \u00e9 instalada no suporte do cilindro de eleva\u00e7\u00e3o durante a instala\u00e7\u00e3o. O ponto fixo do cilindro de eleva\u00e7\u00e3o desce, o bra\u00e7o de momento \u00e9 reduzido, a for\u00e7a de cisalhamento na posi\u00e7\u00e3o fixa do canal \u00e9 reduzida e a probabilidade de fratura do defletor do canal \u00e9 significativamente reduzida.<\/li>\n
  3. \u00c9 adicionada a ranhura de veda\u00e7\u00e3o do defletor do rotor, e a veda\u00e7\u00e3o com tira plana \u00e9 substitu\u00edda por uma veda\u00e7\u00e3o com corda de c\u00e2nhamo, o que aumenta o efeito de veda\u00e7\u00e3o e reduz o custo de produ\u00e7\u00e3o.<\/li>\n
  4. O defletor do canal \u00e9 mais leve do que o anterior, e a \u00e1rea de contato com o l\u00edquido de alum\u00ednio \u00e9 pequena, o que reduz a carga de trabalho do cilindro de eleva\u00e7\u00e3o.<\/li>\n
  5. Aumenta consideravelmente a vida \u00fatil do defletor. Reduz consideravelmente a intensidade do trabalho dos funcion\u00e1rios.<\/li>\n
  6. Melhorar efetivamente a qualidade das lajes. O custo de produ\u00e7\u00e3o das lajes \u00e9 reduzido.<\/li>\n<\/ol>","protected":false},"excerpt":{"rendered":"
