FUSiO2N<\/a>\u2122<\/a>\u00a0O SP da Rex Materials foi especialmente formulado para as tampas que s\u00e3o utilizadas em m\u00e1quinas de fundi\u00e7\u00e3o de lingotes da Wagstaff. O FUSiO2N SP \u00e9 uma composi\u00e7\u00e3o de s\u00edlica fundida de alta pureza, com gr\u00e3os extremamente finos, que proporciona excelentes propriedades de resist\u00eancia ao desgaste e excelente resist\u00eancia ao choque t\u00e9rmico. As propriedades especiais de n\u00e3o-molhamento, al\u00e9m do revestimento industrial com nitreto de boro, impedem a ader\u00eancia do metal e a a\u00e7\u00e3o do alum\u00ednio e outros metais fundidos. O FUSiO2N SP passou por todos os principais testes de resist\u00eancia ao alum\u00ednio especificados pelos principais fabricantes de alum\u00ednio.<\/p>\n

A menor massa t\u00e9rmica e condutividade minimizam a possibilidade de congelamentos durante a inicializa\u00e7\u00e3o ou em baixas taxas de fluxo de metal. Nosso processo especial FUSiO2N SP permite oferecer esse desempenho excepcional a um pre\u00e7o muito razo\u00e1vel. Nosso processo foi projetado de forma a que a superf\u00edcie de contato met\u00e1lica interna dos nossos tamp\u00f5es n\u00e3o apresente praticamente nenhuma porosidade.<\/p>\n

Os testes realizados pelo cliente conclu\u00edram que o FUSiO2N SP dura mais tempo do que os pinzais tradicionais de s\u00edlica fundida. Temos tanta confian\u00e7a na qualidade que oferecemos que oferecemos uma garantia de reembolso!<\/p>\n
