Comment fabrique-t-on le carbure de tungst\u00e8ne ?<\/h2>\n\n\n\n

Carbure de tungst\u00e8ne<\/a> (WC) est un mat\u00e9riau d'une duret\u00e9 extr\u00eamement \u00e9lev\u00e9e, souvent utilis\u00e9 pour fabriquer des produits industriels tels que des outils de coupe, moules<\/a> et les abrasifs. Le processus de production du carbure de tungst\u00e8ne comprend principalement des \u00e9tapes telles que la pr\u00e9paration des mati\u00e8res premi\u00e8res, le m\u00e9lange, le s\u00e9chage, le frittage et le post-traitement. Comment le carbure de tungst\u00e8ne est-il fabriqu\u00e9 ? Je l'expliquerai en d\u00e9tail \u00e0 travers le processus suivant.<\/p>\n\n\n\n

1. Pr\u00e9paration du mat\u00e9riel :<\/p>\n\n\n\n

Tout d'abord, la pr\u00e9paration des mati\u00e8res premi\u00e8res est la premi\u00e8re \u00e9tape de la production de carbure de tungst\u00e8ne. En g\u00e9n\u00e9ral, la m\u00e9tallurgie des poudres est utilis\u00e9e pour m\u00e9langer la poudre de tungst\u00e8ne et la poudre de carbone dans une certaine proportion. La poudre de tungst\u00e8ne est pr\u00e9par\u00e9e par traitement, raffinage et broyage du minerai de tungst\u00e8ne comme mati\u00e8re premi\u00e8re. La poudre de carbone est pr\u00e9par\u00e9e par r\u00e9action de carbonisation avec du graphite comme mati\u00e8re premi\u00e8re.<\/p>\n\n\n\n

\"Comment<\/figure>\n\n\n\n

2. m\u00e9lange de poudres :<\/p>\n\n\n\n

Ensuite, le m\u00e9lange consiste \u00e0 m\u00e9langer la poudre de tungst\u00e8ne et la poudre de carbone selon un certain rapport de formule. Il existe deux m\u00e9thodes courantes de m\u00e9lange. L'une est le m\u00e9lange m\u00e9canique, qui consiste \u00e0 mettre la poudre de tungst\u00e8ne et la poudre de carbone dans un broyeur \u00e0 billes pour les m\u00e9langer de mani\u00e8re \u00e0 ce que la poudre de tungst\u00e8ne et la poudre de carbone soient uniform\u00e9ment r\u00e9parties ; l'autre est le m\u00e9lange humide, qui consiste \u00e0 m\u00e9langer la poudre de tungst\u00e8ne et la poudre de carbone avec un agent complexant organique respectivement, puis \u00e0 les m\u00e9langer.<\/p>\n\n\n\n

3. pressage et moulage\uff1a<\/p>\n\n\n\n

La poudre de carbone de tungst\u00e8ne m\u00e9lang\u00e9e est plac\u00e9e dans un moule pour \u00eatre press\u00e9e et moul\u00e9e. Au cours du processus de pressage, la pression et la dur\u00e9e doivent \u00eatre contr\u00f4l\u00e9es pour garantir que la densit\u00e9 et la forme des pi\u00e8ces moul\u00e9es r\u00e9pondent aux exigences. L'\u00e9tape suivante est le processus de s\u00e9chage, au cours duquel la poudre de carbone tungst\u00e8ne m\u00e9lang\u00e9e est s\u00e9ch\u00e9e \u00e0 haute temp\u00e9rature pour \u00e9liminer l'humidit\u00e9 r\u00e9siduelle. Le s\u00e9chage peut \u00eatre effectu\u00e9 dans un four ou une chambre de s\u00e9chage, et la temp\u00e9rature et la dur\u00e9e sont contr\u00f4l\u00e9es en fonction des exigences sp\u00e9cifiques du processus.<\/p>\n\n\n\n

\"\"<\/a><\/figure>\n\n\n\n

4. frittage :<\/p>\n\n\n\n

Le frittage est l'une des \u00e9tapes cl\u00e9s de la production de carbure de tungst\u00e8ne. La poudre de carbone de tungst\u00e8ne s\u00e9ch\u00e9e est fritt\u00e9e en blocs par chauffage \u00e0 haute temp\u00e9rature. Le frittage<\/a> La temp\u00e9rature est g\u00e9n\u00e9ralement comprise entre 1400\u2103 et 1600\u2103, et doit \u00eatre maintenue pendant un certain temps pour que la poudre de tungst\u00e8ne et la poudre de carbone r\u00e9agissent chimiquement pour former du carbure de tungst\u00e8ne.<\/p>\n\n\n\n

\"Comment<\/a><\/figure>\n\n\n\n

5. le post-traitement\uff1a<\/p>\n\n\n\n

Apr\u00e8s le frittage, un post-traitement est \u00e9galement n\u00e9cessaire, comprenant principalement un traitement thermique et un traitement m\u00e9canique. Le traitement thermique consiste \u00e0 recuire ou \u00e0 surchauffer le corps fritt\u00e9 pour ajuster les propri\u00e9t\u00e9s du mat\u00e9riau et r\u00e9duire les contraintes internes. Le traitement m\u00e9canique consiste \u00e0 couper, tourner, meuler et autres proc\u00e9d\u00e9s sur le carbure de tungst\u00e8ne trait\u00e9 thermiquement pour en faire un produit final conforme aux exigences.<\/p>\n\n\n\n

\"\"<\/a><\/figure>\n\n\n\n

En g\u00e9n\u00e9ral, le processus de production du carbure de tungst\u00e8ne comprend plusieurs \u00e9tapes principales telles que la pr\u00e9paration des mati\u00e8res premi\u00e8res, le m\u00e9lange, le s\u00e9chage, le frittage et le post-traitement. En contr\u00f4lant raisonnablement les param\u00e8tres et les exigences de ces \u00e9tapes, il est possible d'obtenir des mat\u00e9riaux de carbure de tungst\u00e8ne de qualit\u00e9 stable.<\/p>","protected":false},"excerpt":{"rendered":"
