Como estrutura refract\u00e1ria fundamental no processo de produ\u00e7\u00e3o de a\u00e7o, Materiais refract\u00e1rios para revestimento de panelas de fundi\u00e7\u00e3o<\/strong><\/a> deve ter boa resist\u00eancia \u00e0 eros\u00e3o, resist\u00eancia ao choque t\u00e9rmico, resist\u00eancia \u00e0 esc\u00f3ria e resist\u00eancia a altas temperaturas. De acordo com a estrutura da camada de trabalho e a posi\u00e7\u00e3o de utiliza\u00e7\u00e3o, o revestimento da panela inclui normalmente a camada de trabalho, a camada permanente e a camada de isolamento, e os materiais refract\u00e1rios utilizados nas diferentes partes s\u00e3o tamb\u00e9m diferentes.<\/p>\n

\"KERUI-Magnesia-Carbon-Brick\"<\/p>\n

Segue-se a classifica\u00e7\u00e3o dos materiais refract\u00e1rios habitualmente utilizados no revestimento de panelas:<\/p>\n

\u4e00. Camada de trabalho (a parte em contacto com o a\u00e7o fundido e a esc\u00f3ria)<\/h2>\n

T\u00eam de ser resistentes a temperaturas elevadas e \u00e0 corros\u00e3o do a\u00e7o fundido e da esc\u00f3ria:<\/p>\n

1. Tijolo de magn\u00e9sio-carbono<\/a>:<\/strong> normalmente utilizado na parede da concha, no fundo da concha e na zona da boca da concha
\nCarater\u00edsticas: boa resist\u00eancia ao choque t\u00e9rmico e forte resist\u00eancia \u00e0 corros\u00e3o<\/p>\n

2. Tijolo de alta alumina<\/a>:<\/strong> adequado para concha de baixa exig\u00eancia ou \u00e1rea de transi\u00e7\u00e3o
\nBaixo custo e vida \u00fatil m\u00e9dia<\/p>\n

3. Tijolo de alum\u00ednio, magn\u00e9sio e carbono (tijolo Al-Mg-C):<\/strong> pode ser utilizado para o topo da concha e para a zona de impacto
\nBom desempenho global<\/p>\n

4. Material fundido sem carbono<\/strong> \/ Concretos autoflutuantes com baixo teor de carbono (LC Concretos: utilizados para panelas grandes ou refinadas
\nConstru\u00e7\u00e3o c\u00f3moda, boa integridade<\/p>\n

5. Materiais refract\u00e1rios funcionais<\/strong> (tais como bicos de concha de mudan\u00e7a r\u00e1pida, tijolos de assento)
\nUtilizar materiais sinterizados ou electrofundidos para melhorar o desempenho anti-incrustante e anti-eros\u00e3o<\/p>\n

\"Tijolo<\/p>\n

\u4e8c. Camada permanente (camada de trabalho de suporte, proporcionando resist\u00eancia e isolamento)<\/h2>\n

N\u00e3o s\u00e3o necess\u00e1rios requisitos de temperatura elevada, centrando-se no suporte e no isolamento:<\/p>\n

1. Tijolo refrat\u00e1rio<\/a><\/strong>: barato, f\u00e1cil de construir<\/p>\n

2. Tijolo de alta alumina:<\/strong> maior resist\u00eancia, vida \u00fatil prolongada da panela<\/p>\n

3. Tijolo refrat\u00e1rio isolante<\/a> ou aglomerado refrat\u00e1rio leve<\/a>:<\/strong> reduzir a condu\u00e7\u00e3o de calor para a concha da concha<\/p>\n

\u4e09. Camada isolante (camada mais exterior, pr\u00f3xima da concha)<\/h2>\n

Reduzir a perda de calor e proteger a concha:<\/p>\n

1. Painel de fibras de silicato de alumina<\/a> \/ manta de fibra cer\u00e2mica<\/a>:<\/strong> excelente desempenho de isolamento<\/p>\n

2. Tijolo de isolamento leve \/ placa de perlite e outros materiais de isolamento<\/strong><\/p>\n

3. Materiais suplementares:<\/strong>
\nMaterial de vibra\u00e7\u00e3o a seco (revestimento de panelas a seco): utilizado para a fundi\u00e7\u00e3o integral do fundo ou da parede da panela, de constru\u00e7\u00e3o r\u00e1pida
\nBlocos pr\u00e9-fabricados<\/a><\/strong> (Bloco pr\u00e9-fabricado): utilizado para zona de impacto ou tijolo de assento para reduzir o tempo de manuten\u00e7\u00e3o<\/p>\n
