Caracter\u00edsticas dos m\u00e9todos de fundi\u00e7\u00e3o e lamina\u00e7\u00e3o cont\u00ednuas com rolos duplos<\/strong><\/p>\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 reduzir 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
Defini\u00e7\u00e3o da zona de fundi\u00e7\u00e3o-lamina\u00e7\u00e3o: a zona de fundi\u00e7\u00e3o-lamina\u00e7\u00e3o refere-se \u00e0 \u00e1rea entre a linha central dos dois rolos (tamb\u00e9m chamada de linha central dos rolos) e a borda dianteira da ponta da pe\u00e7a fundida de alum\u00ednio.
\nO 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, pela capacidade do equipamento, pela for\u00e7a e pela espessura do l\u00e1bio de pulveriza\u00e7\u00e3o.<\/p>\n

<\/p>\n
Princ\u00edpios gerais para a defini\u00e7\u00e3o da zona de fundi\u00e7\u00e3o e lamina\u00e7\u00e3o<\/strong><\/p>\n1. A espessura da chapa laminada a quente aumenta, e a \u00e1rea laminada a quente diminui.
\n2. O di\u00e2metro do rolo de fundi\u00e7\u00e3o aumenta, e a \u00e1rea de fundi\u00e7\u00e3o tamb\u00e9m aumenta.
\n3. A espessura do bico de vazamento aumenta, e a \u00e1rea de vazamento tamb\u00e9m aumenta.
\n4. A for\u00e7a de lamina\u00e7\u00e3o do equipamento \u00e9 elevada, e a \u00e1rea de fundi\u00e7\u00e3o e lamina\u00e7\u00e3o foi ampliada.
\n5. A zona de lamina\u00e7\u00e3o por fundi\u00e7\u00e3o do alum\u00ednio puro e da liga macia \u00e9 um pouco mais longa, enquanto a zona de lamina\u00e7\u00e3o por fundi\u00e7\u00e3o da liga dura \u00e9 um pouco mais curta.<\/p>\n
A ponta de alimenta\u00e7\u00e3o da fundi\u00e7\u00e3o est\u00e1 localizada na frente dos rolos do equipamento de lamina\u00e7\u00e3o na \u00e1rea de ligas de alum\u00ednio e \u00e9 utilizada para guiar as ligas de alum\u00ednio.<\/p>\n
O alum\u00ednio fundido entra no bico de vazamento pela entrada traseira e, em seguida, \u00e9 descarregado pela sa\u00edda frontal, entrando no rolo, onde \u00e9 resfriado pelo rolo e laminado, formando um lingote fundido.<\/p>\n
Normalmente, a largura do tarugo fundido e laminado \u00e9 determinada pela largura de sa\u00edda do bocal. A fim de melhorar a utiliza\u00e7\u00e3o do equipamento e reduzir os custos operacionais, a largura das chapas produzidas por equipamentos comuns de fundi\u00e7\u00e3o e lamina\u00e7\u00e3o \u00e9 relativamente grande, atingindo geralmente 1.450 mm a 1.600 mm.<\/p>\n
No caso de placas laminadas por fundi\u00e7\u00e3o com largura inferior a 800 mm, se forem utilizados a estrutura de equipamentos e o m\u00e9todo de produ\u00e7\u00e3o tradicionais, a produ\u00e7\u00e3o unit\u00e1ria diminuir\u00e1.<\/p>\n
No processo de fundi\u00e7\u00e3o de ligas de alum\u00ednio, s\u00e3o necess\u00e1rias bra\u00e7adeiras para apoiar e prender os bicos fabricados com materiais refrat\u00e1rios (fr\u00e1geis e quebradi\u00e7os).<\/p>\n
Existem ajustes importantes no ajuste da abertura do bico, no ajuste do formato da placa e no ajuste da \u00e1rea de inje\u00e7\u00e3o de argamassa. Portanto, isso tem um grande impacto na qualidade do produto.<\/p>","protected":false},"excerpt":{"rendered":"
