Atualmente, os fundentes para ligas de alum\u00ednio dividem-se principalmente em dois sistemas: o sistema NaCl-KCl e o sistema KCl-MgCl\u2082. O primeiro cont\u00e9m s\u00f3dio (Na), e o NaCl-KCl equimolar forma um eut\u00e9tico de baixo ponto de fus\u00e3o a 665 \u00b0C, que exerce um forte efeito de umecta\u00e7\u00e3o sobre o Al\u2082O\u2083. Geralmente utilizado em ligas que n\u00e3o s\u00e3o sens\u00edveis a elementos de Na, ele \u00e9 a base da maioria dos fundentes; o segundo, como Fluxo sem Na<\/a>, \u00e9 a base dos fundentes para ligas de alum\u00ednio com alto teor de Mg. A mistura de KCl e MgCl\u2082 apresenta um ponto de fus\u00e3o baixo, entre 424 e 465 \u2103.<\/p>\n

A fim de aumentar o efeito de separa\u00e7\u00e3o entre a esc\u00f3ria e o alum\u00ednio, melhorar a tens\u00e3o superficial do fundente e aprimorar sua capacidade de purifica\u00e7\u00e3o, s\u00e3o adicionados ao fundente aditivos como Na\u2083AlF\u2086 ou K\u2083AlF\u2086 e CaF. A adi\u00e7\u00e3o desses aditivos \u00e9 geralmente dividida em mistura mec\u00e2nica e mistura por refundi\u00e7\u00e3o; a uniformidade da composi\u00e7\u00e3o do fluxo misturado por refundi\u00e7\u00e3o \u00e9 muito superior \u00e0 da mistura mec\u00e2nica e permite obter uma mistura eut\u00e9tica de baixo ponto de fus\u00e3o, mas o custo \u00e9, consequentemente, mais elevado. \u00c9 utilizado para a prepara\u00e7\u00e3o de fluxos de alto desempenho. A premissa b\u00e1sica do m\u00e9todo de mistura por refundi\u00e7\u00e3o \u00e9 dominar as propriedades termodin\u00e2micas da mistura e, em seguida, garantir o ponto de fus\u00e3o do fluxo. Geralmente, a temperatura de fus\u00e3o do fluxo deve ser inferior \u00e0 temperatura de fus\u00e3o durante a fundi\u00e7\u00e3o do alum\u00ednio em mais de 50 \u2103. O fluxo fundido \u00e9 utilizado para promover a adsor\u00e7\u00e3o e a fus\u00e3o das impurezas. Para garantir a capacidade de remo\u00e7\u00e3o de esc\u00f3ria, caso o ponto de fus\u00e3o n\u00e3o atenda aos requisitos, \u00e9 necess\u00e1rio adicionar um agente de aquecimento para promover o r\u00e1pido aumento da temperatura do fluxo, o que complicar\u00e1 a composi\u00e7\u00e3o dos fluxos para ligas de alum\u00ednio.<\/p>\n

Portanto, para avaliar a qualidade do fluxo, devemos primeiro examinar a simplicidade de sua composi\u00e7\u00e3o.<\/p>","protected":false},"excerpt":{"rendered":"
