A ponta de fundi\u00e7\u00e3o de silicato de alum\u00ednio, tamb\u00e9m conhecida como bocal de fundi\u00e7\u00e3o, \u00e9 um componente essencial que transporta e distribui diretamente o metal para o rolo de fundi\u00e7\u00e3o durante o processo de fundi\u00e7\u00e3o e lamina\u00e7\u00e3o cont\u00ednuas. \u00c9 composta por abas de entrada superior e inferior, v\u00e1rios espa\u00e7adores e abas laterais.<\/p>\n

Requisitos de material para pontas de fundi\u00e7\u00e3o de silicato de alum\u00ednio<\/h2>\n

Trata-se de uma placa refrat\u00e1ria fabricada com fibra cer\u00e2mica e fibra de sil\u00edcio-alum\u00ednio por meio de prensagem a v\u00e1cuo. Trata-se de um produto refrat\u00e1rio leve com as seguintes propriedades: boa estabilidade em altas temperaturas; bom isolamento t\u00e9rmico e baixa condutividade t\u00e9rmica; boa resist\u00eancia ao choque t\u00e9rmico; n\u00e3o reage com metal fundido e \u00e9 resistente \u00e0 corros\u00e3o por metais; apresenta bom desempenho na usinagem e pode ser usinado conforme necess\u00e1rio.<\/p>\n

\"Dica<\/p>\n

A estrutura interna do bocal de alimenta\u00e7\u00e3o<\/a> \u00c9 muito importante para a produ\u00e7\u00e3o est\u00e1vel do processo de lamina\u00e7\u00e3o por fundi\u00e7\u00e3o e para a melhoria da qualidade das chapas laminadas por fundi\u00e7\u00e3o. A finalidade do tecido de veda\u00e7\u00e3o interno \u00e9 tornar o campo de temperatura e o campo de fluxo do metal no bocal de alimenta\u00e7\u00e3o o mais uniforme poss\u00edvel. O tamanho, o espa\u00e7amento e a quantidade das veda\u00e7\u00f5es s\u00e3o determinados pelas diferentes estruturas e larguras dos bocais.<\/p>\n

A produ\u00e7\u00e3o do leque de boca. Como o metal solidificado ter\u00e1 uma certa largura ap\u00f3s a lamina\u00e7\u00e3o, de acordo com o chanfro das abas laterais e a composi\u00e7\u00e3o da liga, a largura do leque de boca usinado deve ser 5 a 100 mm menor do que a largura exigida da chapa. As faces finais em ambos os lados do ventilador de boca processado devem estar perpendiculares \u00e0 face final inferior, e as faces finais em ambos os lados devem estar niveladas para garantir que n\u00e3o haja folga entre as abas laterais.<\/p>\n

A espessura da borda frontal do leque de boca varia, em geral, de acordo com o material e a resist\u00eancia do leque de boca. A determina\u00e7\u00e3o da espessura da borda frontal do ventilador de boca deve ser combinada de forma integrada com a liga, a espessura da chapa e a for\u00e7a de lamina\u00e7\u00e3o nas zonas de fundi\u00e7\u00e3o e lamina\u00e7\u00e3o. A espessura da borda frontal do ventilador de boca \u00e9 geralmente de 2,5 a 5 mm.<\/p>","protected":false},"excerpt":{"rendered":"
