Yiziphi Izinqubo Zokunamathisela Zokubumba?

Ukufakwa kwe-annealing kungenye yezinqubo ezibaluleke kakhulu zokwelapha ukushisa ze-forgings, ezisetshenziselwa ukuthuthukisa ukusebenza kwazo, ukunciphisa ukucindezeleka kwangaphakathi, ukuthuthukisa ukuguquguquka, nokuzilungiselela ukucutshungulwa okuqhubekayo. Ukufakwa kwe-annealing, okukhiqizwa ngokubumba insimbi ngaphansi kwamandla aphezulu okucindezela, kuvame ukuba nokucindezeleka okusele kanye namazinga obulukhuni obuguquguqukayo ngenxa yenqubo yokufakwa kwe-annealing. Ukufakwa kwe-annealing kusiza ekucwengisiseni isakhiwo sezinhlamvu nokulungisa izakhiwo zemishini ukuze ukufakwa kwe-annealing kusebenze kahle kakhulu ekusesheni.

Lesi sihloko sihlola incazelo ye-annealing, izizathu zokusetshenziswa kwayo, izinqubo eziyinhloko ze-annealing zokufakelwa, izinyathelo ezihilelekile, kanye nezinzuzo ezinikeza abakhiqizi kanye nabasebenzisi bokugcina.

Isingeniso ku-Annealing for Forgings

I-Annealing inqubo yokushisa nokupholisa elawulwayo eshintsha izakhiwo zensimbi ezibonakalayo futhi ngezinye izikhathi zamakhemikhali ukuze yenze ithambe futhi isebenze kalula. Ekufakeni, inqubo inciphisa ubulukhuni, ithuthukise ukuguquguquka, futhi ikhuthaze isakhiwo esincane esifanayo.

Isetshenziswa ezintweni eziningi zokwakha, okuhlanganisa insimbi yekhabhoni, insimbi ye-alloy, insimbi engagqwali, i-aluminium alloys, i-copper alloys, nezinye izinsimbi ezikhethekile.

Kungani Ukunamathisela Kudingeka Ukuze Kufakwe Izinto Ezingadingekile

  • Kuqeda Ukucindezeleka Kwangaphakathi– Ukufakelwa kungenisa ukucindezeleka ensimbini ngenxa yokuguquguquka nokupholisa okungalingani. Ukufakelwa kunciphisa lokhu kucindezeleka ukuze kuvinjelwe ukuphazamiseka ngesikhathi sokucubungula.
