Kusankha Annealing Process kwa Tin Bronze Sheet

1. Kutentha kutentha, kugwira nthawi ndi njira yozizira: The gawo kusintha kutentha kwambale yamkuwa ya malatakuchokera ku α→ α + ε pafupifupi 320 ℃, ndiye kuti, kutentha kwa kutentha kumakhala kopitilira 320 ℃, ndipo kapangidwe kake ndi gawo limodzi, mpaka kutenthedwa mpaka 930 Gawo lamadzimadzi likuwoneka mozungulira ℃.Poganizira zipangizo ntchito, mlingo wa makutidwe ndi okosijeni wa workpiece pambuyo Kutentha, ndi kwenikweni processing ntchito ya workpiece pambuyo kutentha mankhwala, pambuyo pa malo kuyerekeza ndi kutsimikizira, Kutentha kutentha kwa (350 ± 10) ℃ ndi koyenera.Kutentha kwa kutentha ndikokwera kwambiri, ndipo chogwirira ntchito chimakhala ndi okosijeni kwambiri.
Ngati kutentha kuli kochepa kwambiri, mphamvu ndi elasticity ya workpiece ndipamwamba ndipo kulimba mwachiwonekere sikukwanira, kotero sikuli koyenera kupanga.Chifukwa cha kuchuluka kwa ng'anjo yamoto (230kg / 35kW dzenje ng'anjo), kuti itenthetse ndikupeza mphamvu ndi kulimba kwina, kuti atsogolere kukonzedwa kotsatira, zida zogwirira ntchito mung'anjo iliyonse ziyenera kutenthedwa kwa pafupifupi maola awiri mutatha kutentha.Ikhoza kukhala yoziziritsidwa ndi mpweya, kapena chogwirira ntchito chikhoza kusiyidwa mumgolo wotentha kuti chizizire pang'onopang'ono.
2. Kuzindikiritsa zotsatira za chithandizo cha annealing: Chifukwa cha zinthu zochepa, njira ziwiri zingagwiritsidwe ntchito kuti zizindikire mosavuta workpiece yothandizidwa.Chimodzi ndicho kuyang'ana mtundu wa workpiece, ndiko kuti, ntchito yosamalidwa bwino imasintha kuchokera ku mtundu wa mkuwa woyambirira kupita ku buluu-wakuda.Chachiwiri ndi chakuti workpiece kukonzedwa akhoza kuweruzidwa mwachindunji ndi kupinda ndi dzanja.Popinda, ngati chogwiriracho chikhoza kupindika pokhala ndi mphamvu zina ndi kusungunuka, zikutanthauza kuti mphamvu ya annealing ndi yabwino ndipo ndi yoyenera kupanga.M'malo mwake, mphamvu ndi elasticity ya workpiece pambuyo mankhwala ndi mkulu, ndipo si kophweka kupinda ndi dzanja, kusonyeza kuti annealing mankhwala zotsatira si zabwino, ndipo ayenera annealed kachiwiri.
3. Zida ndi ng'anjo yoyikira njira: Kuti mukwaniritse cholinga cha kutentha ndi anti-oxidation, zida zamkuwa zamkuwa nthawi zambiri sizoyenera kukonzedwa m'ng'anjo zamabokosi popanda kuyambitsa mafani.Mwachitsanzo, pansi pa chikhalidwe cha ng'anjo yemweyo (mphamvu ya ng'anjo ndi 230kg / 35kW), workpiece imachitidwa mu ng'anjo ya bokosi popanda kusonkhezera fani ndi dzenje lotentha ng'anjo ndi fani yolimbikitsa, motero.Pansi pa njira yomweyo annealing mikhalidwe Kutentha pa (350 ± 10) ℃, kugwira kwa 2h ndiyeno mpweya kuziziritsa, zotsatira za mankhwala awiri osiyana kwambiri.
Zida zogwirira ntchito zomwe zimagwiritsidwa ntchito ndi ng'anjo ya bokosi zimakhala ndi kuwala kosiyana, mphamvu zambiri komanso kulimba kosakwanira, zomwe zimakhala zovuta kupindika.Pambuyo pokonza mtanda womwewo wa zida zogwirira ntchito ndi ng'anjo yowotcha dzenje, kuwalako kumakhala kofanana, ndipo mphamvu ndi kulimba ndizoyenera, zomwe zimathandiza kuti ntchito zotsatila zitheke.Chifukwa chake, kwa mabizinesi omwe ali ndi malire, chithandizo cha annealing chimatha kukonzedwa ndi ng'anjo ya dzenje, ndipo mbiya yotentha yokhala ndi mphamvu yayikulu ingagwiritsidwe ntchito kulipiritsa.Zida zogwirira ntchito ziyenera kuyikidwa bwino kuti zisawonongeke zogwirira ntchito chifukwa cha kukakamizidwa.
