O brilho do tubo de a\u00e7o inoxid\u00e1vel<\/a> ap\u00f3s o recozimento determina a qualidade do produto. <\/p>\n\n\n\n

\"Tubos<\/figure>\n\n\n\n

Muitos fatores afetam seu brilho. Aqui est\u00e3o os cinco fatores mais importantes para todos:<\/p>\n\n\n\n

1. Se a temperatura do recozimento atingir a temperatura especificada. O tratamento t\u00e9rmico dos acess\u00f3rios para tubos de a\u00e7o inoxid\u00e1vel \u00e9 geralmente um tratamento t\u00e9rmico de solu\u00e7\u00e3o, que \u00e9 normalmente chamado de \"recozimento\". A faixa de temperatura \u00e9 de 1040 ~ 1120 graus (padr\u00e3o japon\u00eas). Tamb\u00e9m \u00e9 poss\u00edvel observar atrav\u00e9s do orif\u00edcio de observa\u00e7\u00e3o do forno de recozimento. <\/p>\n\n\n\n

Os acess\u00f3rios para tubos de a\u00e7o inoxid\u00e1vel na zona de recozimento devem ser incandescentes, mas n\u00e3o h\u00e1 amaciamento<\/a> descair.<\/p>\n\n\n\n

2. Geralmente, o hidrog\u00eanio puro \u00e9 usado como atmosfera de recozimento. A pureza da atmosfera \u00e9 preferencialmente acima de 99.99%. Se a outra parte da atmosfera for um g\u00e1s inerte, a pureza pode ser menor, mas n\u00e3o deve conter muito oxig\u00eanio e vapor de \u00e1gua.<\/p>\n\n\n\n

3. Veda\u00e7\u00e3o do corpo do forno O forno de recozimento brilhante deve ser fechado e isolado do ar externo; usando hidrog\u00eanio como g\u00e1s de prote\u00e7\u00e3o, apenas uma porta de exaust\u00e3o \u00e9 aberta (usada para inflamar o hidrog\u00eanio descarregado).<\/p>\n\n\n\n

O m\u00e9todo de inspe\u00e7\u00e3o pode ser limpo com \u00e1gua e sab\u00e3o nas aberturas de cada junta do forno de recozimento para verificar se h\u00e1 vazamento de ar.<\/p>\n\n\n\n

O local onde o g\u00e1s tem maior probabilidade de vazar \u00e9 o local onde o forno entra no tubo e o local onde o tubo sai. O anel de veda\u00e7\u00e3o neste local \u00e9 particularmente sujeito a desgaste e \u00e9 necess\u00e1rio verific\u00e1-lo e troc\u00e1-lo com frequ\u00eancia.<\/p>\n\n\n\n

4. Para evitar micro vazamentos, a press\u00e3o do g\u00e1s de prote\u00e7\u00e3o no forno deve ser mantida em um determinado valor positivo. Se for um g\u00e1s de prote\u00e7\u00e3o de hidrog\u00eanio, geralmente \u00e9 necess\u00e1rio estar acima de 20K Bar.<\/p>\n\n\n\n

5. Verifique se o material do forno est\u00e1 seco. O material do forno deve ser seco pela primeira vez e, em seguida, o tubo de a\u00e7o inoxid\u00e1vel antes de entrar no forno n\u00e3o deve deixar muitas manchas de \u00e1gua. N\u00e3o deixe entrar \u00e1gua, caso contr\u00e1rio, a atmosfera da fornalha ser\u00e1 totalmente destru\u00edda.<\/p>\n\n\n\n

Geralmente, se for normal, o tubo de a\u00e7o inoxid\u00e1vel que deve ser recuado cerca de 20 metros ap\u00f3s o forno come\u00e7ar\u00e1 a brilhar e refletir.<\/p>\n\n\n\n

Mencionamos todos os assuntos que precisam de aten\u00e7\u00e3o acima, espero que todos possam prestar aten\u00e7\u00e3o a eles durante a produ\u00e7\u00e3o.<\/p>\n\n\n\n
