Bright Annealed(BA) Seamless Tube
Mafotokozedwe Akatundu
Kuwotchera kowala ndi njira yotsekera yomwe imachitidwa mu vacuum kapena mumlengalenga wowongolera wokhala ndi mpweya wopanda mpweya (monga haidrojeni). Mpweya wolamulidwa umenewu umachepetsa kutsekemera kwa okosijeni pamtunda pang'ono zomwe zimapangitsa kuti pakhale malo owala komanso wosanjikiza wochepa kwambiri wa oxide. Pickling sikufunika pambuyo pa annealing owala chifukwa makutidwe ndi okosijeni ndi kochepa. Popeza palibe pickling, pamwamba ndi yosalala kwambiri zomwe zimabweretsa kukana bwino kwa pitting dzimbiri.
Kuchiza kowala kumasunga kusalala kwa pamwamba, ndipo mawonekedwe owala amatha kupezeka popanda kukonzanso pambuyo. Pambuyo pa annealing yowala, pamwamba pa chubu chachitsulo chimakhalabe ndi chitsulo choyambirira chachitsulo, ndipo malo owala pafupi ndi galasi akupezeka. Pazofuna zambiri, pamwamba pakhoza kugwiritsidwa ntchito mwachindunji popanda kukonzedwa.
Kuti ma annealing owala bwino agwire bwino ntchito, Timayeretsa poyera pamalo a chubu komanso opanda zinthu zakunja tisanalowetse. Ndipo timasunga kuti mpweya wa ng'anjo ukhale wopanda okosijeni (ngati pakufunika chotsatira chowala). Izi zimatheka pochotsa pafupifupi mpweya wonse (kupanga vacuum) kapena kuchotsa mpweya ndi nayitrogeni ndi hydrogen wouma kapena argon.
Vacuum yowala kwambiri imatulutsa chubu choyera kwambiri. Chubuchi chimakwaniritsa zofunikira pamizere yoperekera mpweya woyeretsedwa kwambiri monga kusalala kwamkati, ukhondo, kukana dzimbiri komanso kuchepetsedwa kwa mpweya ndi tinthu tachitsulo.
mankhwala ntchito mwatsatanetsatane zida, zipangizo zachipatala, semiconductor makampani mkulu chiyero payipi, payipi galimoto, labotale mpweya payipi, Azamlengalenga ndi haidrojeni makampani unyolo (otsika kuthamanga, sing'anga kuthamanga, kuthamanga) Ultra mkulu kuthamanga (UHP) zosapanga dzimbiri chitoliro ndi zina. minda.
Tilinso ndi machubu opitilira 100,000 metres, omwe amatha kukumana ndi makasitomala ndi nthawi yobweretsera mwachangu.

Annealing ndi njira yochizira kutentha yomwe imasintha thupi komanso nthawi zina komanso mankhwala azinthu kuti awonjezere ductility ndikuchepetsa kuuma kuti zitheke. The annealing ndondomeko amafuna zinthu pamwamba ake recrystallization kutentha kwa nthawi yoikika pamaso kuzirala.
Annealing ndi njira yochizira kutentha yomwe imagwiritsidwa ntchito posintha zitsulo ndi zida zina, kuti zikhale zofewa, zofewa, komanso zocheperako. Zimaphatikizapo kutenthetsa zinthuzo ku kutentha kwapadera ndiyeno kuzizizira pang'onopang'ono m'njira yoyendetsedwa, kuti mugwiritse ntchito mawonekedwe a crystalline.
