Vis\u00e3o Geral do Forno de Vidro<\/h2>\n

Forno de fus\u00e3o de vidro \u00e9 um equipamento t\u00e9rmico para o fabrico de vidro, habitualmente feito de materiais refract\u00e1rios. Utiliza a energia qu\u00edmica de combust\u00edveis, energia el\u00e9ctrica ou outra energia para gerar calor, criando um ambiente de alta temperatura control\u00e1vel, no qual a mat\u00e9ria-prima do vidro sofre o processo de transfer\u00eancia de calor, transfer\u00eancia de massa e transfer\u00eancia de momento, completando as altera\u00e7\u00f5es f\u00edsicas e qu\u00edmicas, sendo fundido, refinado e homogeneizado. Durante as etapas de fus\u00e3o e arrefecimento, s\u00e3o fornecidas uma determinada quantidade e qualidade de vidro fundido para a produ\u00e7\u00e3o.

Materiais Refrat\u00e1rios para V\u00e1rias Partes do Forno<\/h2>\n

Na ind\u00fastria vidreira, a qualidade dos materiais refract\u00e1rios reveste-se de grande import\u00e2ncia para melhorar a qualidade dos produtos de vidro, poupar combust\u00edvel, prolongar a vida \u00fatil do forno e reduzir os custos de produ\u00e7\u00e3o do vidro. Os materiais refract\u00e1rios s\u00e3o a base material dos fornos de vidro. T\u00eam um enorme impacto na efici\u00eancia global do forno e devem ser seleccionados de forma racional. As condi\u00e7\u00f5es de trabalho das v\u00e1rias partes do forno de cuba s\u00e3o diferentes, pelo que o desempenho dos materiais refract\u00e1rios necess\u00e1rios tamb\u00e9m difere.

\"Tijolo<\/div><\/div>
\"tijolo<\/div><\/div>
<\/div><\/p>\n

(1) Azulejos para Paredes de Piscina<\/strong><\/p>\n

Os tijolos da parede da piscina s\u00e3o feitos de tijolos AZS ou tijolos de pedra de quartzo denso.<\/p>\n

(2) Tijolos para o Fundo da Piscina<\/strong><\/p>\n

Os blocos do fundo do cadinho devem ser resistentes ao desgaste e ter integridade, pelo que s\u00e3o frequentemente utilizadas estruturas de fundo de cadinho compostas por v\u00e1rias camadas. As estruturas multicamadas t\u00eam geralmente uma camada de isolamento por baixo da camada principal de grandes blocos refrat\u00e1rios de argila. S\u00e3o habitualmente utilizados blocos fundidos AZS com boa resist\u00eancia \u00e0 corros\u00e3o e ao desgaste.<\/p>\n

(3) Blocos para Tanques de Alimenta\u00e7\u00e3o<\/strong><\/p>\n

Tijolos de corindo de zirc\u00f3nio fundido contendo ZrO 41%2<\/sub> s\u00e3o habitualmente usados sem furos de retra\u00e7\u00e3o; tijolos AZS-33 de fundi\u00e7\u00e3o comum podem ser utilizados noutras partes. Grandes tijolos de caulinite fundida tamb\u00e9m podem ser considerados para os tijolos inferiores do canal de alimenta\u00e7\u00e3o.<\/p>\n

(4) Bloco de Furo L\u00edquido<\/strong><\/p>\n

O furo de escoamento utiliza blocos de AZS-41 sem furos de retra\u00e7\u00e3o.<\/p>\n

(5) Tijolos para Piscinas de Arrefecimento e Piscinas de Forma\u00e7\u00e3o<\/strong><\/p>\n

A bacia de arrefecimento requer blocos de AZS produzidos pelo m\u00e9todo de oxida\u00e7\u00e3o, que t\u00eam uma elevada temperatura de precipita\u00e7\u00e3o da fase v\u00edtrea e n\u00e3o trazem bolhas para o vidro. A bacia de conforma\u00e7\u00e3o utiliza \u03b1-Al2O3 eletrofundido2<\/sub>O3<\/sub> tijolos.<\/p>\n

(6) Tijolos para Ab\u00f3bada de Forno e Parapeito<\/strong><\/p>\n

Podem ser utilizados tijolos de s\u00edlica, tijolos de s\u00edlica de alta qualidade e tijolos de AZS-33 fundidos.<\/p>\n

(7) Tijolos para a Parede Frontal e Muro de Treli\u00e7a<\/strong><\/p>\n

Atualmente, s\u00e3o utilizados blocos eletrofundidos de AZS-33, sendo tamb\u00e9m empregues em combina\u00e7\u00e3o tijolos de s\u00edlica de alta qualidade e tijolos de AZS sinterizados.<\/p>\n

(8) Tijolos para Pequeno Forno<\/strong><\/p>\n

Os blocos do queimador s\u00e3o constitu\u00eddos por tijolos, os tijolos das paredes laterais e da sola do queimador, e os bicos s\u00e3o feitos de tijolos AZS-33 fundidos. A sola tamb\u00e9m pode ser feita de tijolos de corindo denso sinterizado.<\/p>\n

(9) Materiais Refrat\u00e1rios para Pe\u00e7as Especiais<\/strong><\/p>\n

Existem algumas partes da alvenaria do forno de piscina, tais como orif\u00edcios de bolhas, soleiras do forno, orif\u00edcios para el\u00e9trodos, orif\u00edcios de inspe\u00e7\u00e3o, orif\u00edcios de medi\u00e7\u00e3o, etc. Geralmente, utilizam-se tijolos de corindo de zirc\u00f3nio fundido sem retra\u00e7\u00e3o, contendo 41% ZrO2<\/sub> s\u00e3o utilizados os produzidos pelo m\u00e9todo de oxida\u00e7\u00e3o. Este material apresenta fraca resist\u00eancia \u00e0 vibra\u00e7\u00e3o t\u00e9rmica. Pode considerar a utiliza\u00e7\u00e3o de tijolos de quartzo fundido ou de zirc\u00f3nio denso produzidos pelo m\u00e9todo de sinteriza\u00e7\u00e3o. Os orif\u00edcios de medi\u00e7\u00e3o e de inspe\u00e7\u00e3o utilizam habitualmente tijolos personalizados de corindo de zirc\u00f3nio fundido contendo 41% ZrO2<\/sub>.<\/p>\n

Numa palavra, os blocos AZS s\u00e3o os principais materiais refract\u00e1rios necess\u00e1rios para fornos de vidro. A Kerui Refractory, como l\u00edder na ind\u00fastria refract\u00e1ria, tem nos blocos AZS os seus principais produtos de excel\u00eancia.
