fundi\u00e7\u00e3o a quente<\/a> e atende a elevados requisitos de produ\u00e7\u00e3o. As necessidades t\u00e9cnicas dos produtos de fundi\u00e7\u00e3o de precis\u00e3o em liga de alum\u00ednio \u2014 como os destinados \u00e0 avia\u00e7\u00e3o, aos transportes e aos produtos eletr\u00f4nicos \u2014 exigem alto valor agregado e alto desempenho t\u00e9cnico.<\/p>\nVantagens dos an\u00e9is de grafite para hastes de alum\u00ednio<\/strong><\/p>\n1. O anel de grafite com haste de alum\u00ednio apresenta boa resist\u00eancia ao atrito, superf\u00edcie esmaltada lisa, alta precis\u00e3o de usinagem geom\u00e9trica e baixo custo de manuten\u00e7\u00e3o.
\n2. N\u00e3o h\u00e1 delamina\u00e7\u00e3o nem descascamento, o que reduz efetivamente a polui\u00e7\u00e3o do alum\u00ednio fundido e permite a fundi\u00e7\u00e3o de precis\u00e3o de alum\u00ednio sem polui\u00e7\u00e3o;
\n3. Resist\u00eancia \u00e0 eros\u00e3o, boa resist\u00eancia ao choque t\u00e9rmico e maior resist\u00eancia \u00e0 corros\u00e3o causada por metal fundido;
\n4. A vida \u00fatil \u00e9 normalmente de 800 a 1.200 ciclos de fundi\u00e7\u00e3o, o que permite economizar energia e reduzir o consumo.<\/p>\n
A grafite \u00e9 quimicamente est\u00e1vel e resistente a \u00e1cidos, \u00e1lcalis e solventes org\u00e2nicos. Devido \u00e0s propriedades \u00fanicas e excelentes da grafite mencionadas acima, ela tem sido amplamente utilizada na ind\u00fastria moderna.<\/p>\n
Utilizado como material refrat\u00e1rio: a grafite e seus derivados apresentam propriedades de resist\u00eancia a altas temperaturas e alta resist\u00eancia mec\u00e2nica. Na ind\u00fastria metal\u00fargica, \u00e9 utilizada principalmente na fabrica\u00e7\u00e3o de hastes de alum\u00ednio, an\u00e9is de grafite e cadinhos de grafite.<\/p>\n
Como material condutor: Utilizado na ind\u00fastria el\u00e9trica para a fabrica\u00e7\u00e3o de eletrodos, escovas, hastes de carbono, tubos de carbono, eletrodos positivos de dispositivos de corrente positiva de merc\u00fario, arruelas de grafite, pe\u00e7as para telefones, revestimentos para tubos de imagem de televis\u00e3o, etc.<\/p>\n
Como material lubrificante resistente ao desgaste: a grafite \u00e9 frequentemente utilizada como lubrificante na ind\u00fastria de maquin\u00e1rio. O \u00f3leo lubrificante n\u00e3o pode ser utilizado em condi\u00e7\u00f5es de alta velocidade, alta temperatura e alta press\u00e3o, enquanto os materiais de grafite resistentes ao desgaste podem operar em alta velocidade de deslizamento a temperaturas entre 200 e 2.000 \u2103 sem a necessidade de \u00f3leo lubrificante. Muitos equipamentos que transportam meios corrosivos utilizam amplamente materiais de grafite na fabrica\u00e7\u00e3o de copos de pist\u00e3o, veda\u00e7\u00f5es e rolamentos.<\/p>","protected":false},"excerpt":{"rendered":"
