La luminosit\u00e9 de la tuyau en acier inoxydable<\/a> apr\u00e8s recuit d\u00e9termine la qualit\u00e9 du produit. <\/p>\n\n\n\n

\"Tubes<\/figure>\n\n\n\n

De nombreux facteurs affectent sa luminosit\u00e9. Voici les cinq facteurs les plus importants pour tout le monde :<\/p>\n\n\n\n

1. Si la temp\u00e9rature de recuit atteint la temp\u00e9rature sp\u00e9cifi\u00e9e. Le traitement thermique des raccords de tuyauterie en acier inoxydable est g\u00e9n\u00e9ralement un traitement thermique de mise en solution, g\u00e9n\u00e9ralement appel\u00e9 \" recuit \". La plage de temp\u00e9rature est de 1040 ~ 1120 degr\u00e9s (norme japonaise). Vous pouvez \u00e9galement observer par le trou d'observation du four de recuit. <\/p>\n\n\n\n

Les raccords de tuyauterie en acier inoxydable dans la zone de recuit devraient \u00eatre incandescents, mais il n'y en a pas. adoucissement<\/a> sag.<\/p>\n\n\n\n

2. G\u00e9n\u00e9ralement, de l'hydrog\u00e8ne pur est utilis\u00e9 comme atmosph\u00e8re de recuit. La puret\u00e9 de l'atmosph\u00e8re est de pr\u00e9f\u00e9rence sup\u00e9rieure \u00e0 99,99%. Si l'autre partie de l'atmosph\u00e8re est un gaz inerte, la puret\u00e9 peut \u00eatre moindre, mais elle ne doit pas contenir trop d'oxyg\u00e8ne et de vapeur d'eau.<\/p>\n\n\n\n

3. Etanch\u00e9it\u00e9 du corps du four Le four de recuit brillant doit \u00eatre ferm\u00e9 et isol\u00e9 de l'air ext\u00e9rieur ; en utilisant l'hydrog\u00e8ne comme gaz protecteur, un seul orifice d'\u00e9chappement est ouvert (utilis\u00e9 pour enflammer l'hydrog\u00e8ne d\u00e9charg\u00e9).<\/p>\n\n\n\n

La m\u00e9thode d'inspection peut \u00eatre essuy\u00e9e avec de l'eau savonneuse dans les interstices de chaque joint du four de recuit pour voir s'il y a des fuites d'air.<\/p>\n\n\n\n

L'endroit o\u00f9 le gaz est le plus susceptible de fuir est l'endroit o\u00f9 la fournaise entre dans le tuyau et l'endroit o\u00f9 le tuyau sort. La bague d'\u00e9tanch\u00e9it\u00e9 \u00e0 cet endroit est particuli\u00e8rement sujette \u00e0 l'usure et il est n\u00e9cessaire de la v\u00e9rifier fr\u00e9quemment et de la changer fr\u00e9quemment.<\/p>\n\n\n\n

4. Afin d'\u00e9viter les micro fuites, la pression du gaz protecteur dans le four doit \u00eatre maintenue \u00e0 une certaine valeur positive. S'il s'agit d'un gaz protecteur d'hydrog\u00e8ne, il doit g\u00e9n\u00e9ralement \u00eatre sup\u00e9rieur \u00e0 20K Bar.<\/p>\n\n\n\n

5. V\u00e9rifiez si le mat\u00e9riau du four est sec. Le mat\u00e9riau du four doit \u00eatre s\u00e9ch\u00e9 pour la premi\u00e8re fois, puis le tuyau en acier inoxydable avant d'entrer dans le four ne doit pas laisser trop de taches d'eau. Ne laissez pas entrer d'eau, sinon l'atmosph\u00e8re du four sera compl\u00e8tement bris\u00e9e.<\/p>\n\n\n\n

G\u00e9n\u00e9ralement, si c'est normal, le tuyau en acier inoxydable qui doit \u00eatre recul\u00e9 environ 20 m\u00e8tres apr\u00e8s le four commencera \u00e0 briller et \u00e0 se refl\u00e9ter.<\/p>\n\n\n\n

Nous avons mentionn\u00e9 toutes les questions n\u00e9cessitant une attention ci-dessus, j'esp\u00e8re que tout le monde pourra y pr\u00eater attention lors de la production.<\/p>\n\n\n\n
