De acordo com os diferentes setores, as calhas refrat\u00e1rias pr\u00e9-fabricadas apresentam diversas formas e tamanhos. Elas tamb\u00e9m podem ser chamadas de canais, calhas ou por muitos outros nomes espec\u00edficos do setor. Sua variedade abrange desde instala\u00e7\u00f5es in situ muito simples at\u00e9 pe\u00e7as pr\u00e9-fabricadas sob medida para configura\u00e7\u00f5es em Y ou T e componentes para controle de fluxo.<\/p>\n

Os canais de vazamento e as calhas representam um desafio especial para os refrat\u00e1rios. \u00c9 nessas \u00e1reas que os refrat\u00e1rios s\u00e3o submetidos \u00e0 maior velocidade do metal e sofrem maior desgaste.<\/p>\n

A pia de alum\u00ednio \u00e9 uma calha, geralmente revestida por dentro, destinada a transporte de alum\u00ednio fundido<\/a>. A calha de alum\u00ednio \u00e9 um bom isolante que n\u00e3o \u00e9 molhada pelo alum\u00ednio fundido e possui excelente resist\u00eancia mec\u00e2nica, incluindo resist\u00eancia \u00e0 abras\u00e3o por metais e a danos f\u00edsicos.<\/p>\n

Os canais refrat\u00e1rios s\u00e3o o equipamento b\u00e1sico para a fundi\u00e7\u00e3o de ligas de alum\u00ednio. Sua principal fun\u00e7\u00e3o \u00e9 transferir o alum\u00ednio fundido do forno de mistura para a m\u00e1quina de fundi\u00e7\u00e3o. O canal de fundi\u00e7\u00e3o \u00e9 projetado especialmente para materiais refrat\u00e1rios tradicionais resistentes a altas temperaturas. Durante o uso, o alum\u00ednio adere facilmente \u00e0 superf\u00edcie. O operador pode limpar a calha por at\u00e9 30 minutos, o que pode facilmente causar danos ao material refrat\u00e1rio e permitir que o alum\u00ednio l\u00edquido em alta temperatura penetre no material, resultando na deforma\u00e7\u00e3o gradual da chapa de a\u00e7o do inv\u00f3lucro. Al\u00e9m disso, sempre que o canal de fundi\u00e7\u00e3o passa por manuten\u00e7\u00e3o, o material de fundi\u00e7\u00e3o precisa ser removido, e a chapa de a\u00e7o do inv\u00f3lucro deve ser calibrada e reconstru\u00edda. O processo de manuten\u00e7\u00e3o \u00e9 trabalhoso.<\/p>\n

\"\"<\/p>\n

O material refrat\u00e1rio utilizado no tipo de calha \u00e9 um material refrat\u00e1rio n\u00e3o moldado. N\u00e3o possui especifica\u00e7\u00f5es de tamanho espec\u00edficas. Basta levar em considera\u00e7\u00e3o os materiais e o ambiente. Em ambientes de alta temperatura, ele apresenta desempenho contra corros\u00e3o \u00e1cida, corros\u00e3o alcalina, resist\u00eancia ao desgaste e resist\u00eancia \u00e0 eros\u00e3o. Em condi\u00e7\u00f5es de trabalho, devem ser selecionados bet\u00f5es refrat\u00e1rios adequados de acordo com o ambiente de aplica\u00e7\u00e3o e as propriedades.<\/p>\n

Recomendamos o uso de canais de fibra cer\u00e2mica em vez dos canais de vazamento tradicionais, o que aumenta a dist\u00e2ncia de transmiss\u00e3o do metal e reduz a queda de temperatura. Combinados com a placa Adtech como cobertura isolante, eles podem gerar uma economia significativa de energia.<\/p>\n

A Adtech oferece diversas solu\u00e7\u00f5es comprovadas para garantir a maior vida \u00fatil poss\u00edvel nessas \u00e1reas.
