Existem muitos materiais refract\u00e1rios<\/a><\/strong> normalmente utilizados nos fornos de ustula\u00e7\u00e3o de carbono. Seguem-se alguns dos tipos mais comuns:<\/p>\n

Tijolos refract\u00e1rios<\/strong><\/h3>\n

1. Tijolos refract\u00e1rios de barro<\/strong><\/a>: A argila \u00e9 a principal mat\u00e9ria-prima, contendo alto teor de alumina e s\u00edlica. Tem boa estabilidade t\u00e9rmica e certa resist\u00eancia \u00e0 corros\u00e3o, e o pre\u00e7o \u00e9 relativamente baixo. \u00c9 frequentemente utilizada na parede do forno, no teto do forno e noutras partes dos fornos de torrefa\u00e7\u00e3o de carbono.<\/p>\n

\"\"<\/p>\n

2. Tijolos de alta alumina<\/a><\/strong>: O principal componente \u00e9 a alumina, que pode ser dividida em diferentes graus de acordo com o teor de alumina. Tem alta refractariedade, boa resist\u00eancia a altas temperaturas e resist\u00eancia ao choque t\u00e9rmico, e forte resist\u00eancia \u00e0 eros\u00e3o da esc\u00f3ria. \u00c9 frequentemente utilizado em pe\u00e7as-chave, como a \u00e1rea de alta temperatura do fundo do forno e a parede do forno.<\/p>\n

3. Tijolos de s\u00edlica<\/strong><\/a>: O componente principal \u00e9 a s\u00edlica, que tem boa estabilidade de volume a alta temperatura, baixo coeficiente de expans\u00e3o t\u00e9rmica e alta temperatura de amolecimento de carga, e pode manter boa forma e resist\u00eancia a alta temperatura. \u00c9 geralmente utilizado no teto do forno de fornos de torrefa\u00e7\u00e3o de carbono e noutras pe\u00e7as que t\u00eam requisitos de alta temperatura e requerem um bom desempenho de isolamento t\u00e9rmico.<\/p>\n

4. Tijolo de corindo<\/a><\/strong>: Com o corindo (alumina) como principal mat\u00e9ria-prima, tem excelentes propriedades, tais como elevada pureza, elevada dureza, resist\u00eancia a altas temperaturas, resist\u00eancia ao desgaste e resist\u00eancia \u00e0 eros\u00e3o. \u00c9 frequentemente utilizado em partes de fornos de torrefa\u00e7\u00e3o de carbono que est\u00e3o muito desgastadas e corro\u00eddas, tais como portas de fornos, portas de alimenta\u00e7\u00e3o, etc.<\/p>\n

5. Tijolo de mulite<\/strong><\/a>: \u00c9 composto principalmente de minerais de mulita, tem boa resist\u00eancia ao choque t\u00e9rmico, resist\u00eancia a altas temperaturas e estabilidade qu\u00edmica, e tamb\u00e9m tem uma baixa condutividade t\u00e9rmica e bom desempenho de isolamento t\u00e9rmico. Pode ser utilizado na parede do forno, no teto do forno e noutras partes do forno de torrefa\u00e7\u00e3o de carbono.<\/p>\n

6. Tijolo de carboneto de sil\u00edcio<\/strong><\/a>: O componente principal \u00e9 o carboneto de sil\u00edcio, que tem elevada condutividade t\u00e9rmica, elevada dureza, resist\u00eancia a altas temperaturas, resist\u00eancia ao desgaste, resist\u00eancia \u00e0 oxida\u00e7\u00e3o e resist\u00eancia \u00e0 eros\u00e3o. Tem alta condutividade t\u00e9rmica, pode efetivamente transferir calor, encurtar o ciclo de torrefa\u00e7\u00e3o e melhorar a efici\u00eancia da produ\u00e7\u00e3o. \u00c9 frequentemente utilizado no fundo do forno, no revestimento da parede do forno e noutras partes do forno de torrefa\u00e7\u00e3o de carbono.<\/p>\n

Insulation Materials<\/h3>\n

7. Materiais de isolamento<\/a><\/strong>O material de revestimento do forno \u00e9 composto por tijolos leves de argila, l\u00e3 de rocha, fibras cer\u00e2micas, etc. As suas carater\u00edsticas comuns s\u00e3o a baixa densidade e a baixa condutividade t\u00e9rmica, o que pode reduzir eficazmente a perda de calor do corpo do forno e reduzir o consumo de energia. \u00c9 normalmente utilizado para a camada exterior da parede do forno, o teto do forno e a camada de isolamento do tubo do forno de torrefa\u00e7\u00e3o de carbono.<\/p>\n

8. Tijolo de cordierite: O principal componente \u00e9 a cordierite, que tem um baixo coeficiente de expans\u00e3o t\u00e9rmica, boa resist\u00eancia ao choque t\u00e9rmico e bom desempenho de isolamento t\u00e9rmico. A sua resist\u00eancia estrutural a altas temperaturas \u00e9 boa e pode, em certa medida, resistir ao stress t\u00e9rmico e ao stress mec\u00e2nico no forno. \u00c9 frequentemente utilizado em partes de fornos de torrefa\u00e7\u00e3o de carbono que requerem uma elevada resist\u00eancia ao choque t\u00e9rmico, como as partes m\u00e9dia e superior da parede do forno.<\/p>\n

9. Tijolo de espin\u00e9lio de magn\u00e9sio-alum\u00ednio<\/strong><\/a>: O espin\u00e9lio de magn\u00e9sio-alum\u00ednio sintetizado a partir de \u00f3xido de magn\u00e9sio e \u00f3xido de alum\u00ednio \u00e9 a principal fase cristalina, com boa resist\u00eancia ao choque t\u00e9rmico, resist\u00eancia a altas temperaturas e resist\u00eancia \u00e0 eros\u00e3o. Pode manter uma estrutura est\u00e1vel a alta temperatura e resistir \u00e0 eros\u00e3o e ao desgaste de v\u00e1rias subst\u00e2ncias no forno. \u00c9 frequentemente utilizado na porta do forno, na boca do forno e noutras partes do forno de torrefa\u00e7\u00e3o de carbono.<\/p>\n
