Kusiyana kwakukulu pakati pa annealing ndi normalizing:

1. Kuzizira kozizira kumathamanga pang'ono kuposa kuzizira, ndipo kuchuluka kwa kuzizira kwakukulu ndi kwakukulu.
2. Kapangidwe kamene kamapezeka pambuyo pa normalizing ndi bwino, ndipo mphamvu ndi kuuma ndi apamwamba kuposa annealing.

Kusankha annealing ndi normalizing:

1. Pa mapaipi achitsulo opanda mpweya opanda mpweya okhala ndi mpweya wochepera 0.25%, normalizing imagwiritsidwa ntchito m'malo mwa annealing. Chifukwa kuzirala kwachangu kumatha kuletsa chitoliro chochepa cha carbon seamless steel chitoliro kuti chisagwere mvula ya simenti yapamwamba yaulele m'malire a tirigu, potero kumapangitsa kuzizira kwa magwiridwe antchito a zidindo; normalizing akhoza kusintha kuuma kwa chitsulo ndi ntchito kudula wa otsika mpweya Msoko zitsulo chitoliro. ; Ngati palibe njira ina yochizira kutentha, kukhazikika kumatha kuyenga mbewu ndikuwongolera mphamvu zamapaipi achitsulo opanda mpweya.

2. Chitoliro chachitsulo chosakanizika chokoka mpweya chozizira chokhala ndi mpweya wapakati pa 0.25% ndi 0.5% chimathanso kukhala chokhazikika m'malo momangirira. Ngakhale sing'anga-mpweya mpweya zitsulo ozizira kukokedwa opanda msokonezo chitoliro ndi mpweya zili pafupi malire chapamwamba ali kuuma mkulu pambuyo normalizing, akadali Ikhoza kudulidwa, ndipo normalizing mtengo ndi otsika ndi zokolola ndi mkulu.

3. Cold-kokedwa seamless zitsulo mapaipi okhala ndi mpweya zili pakati pa 0,5 ndi 0.75%, chifukwa cha carbon okhutira, kuuma pambuyo normalizing ndi apamwamba kwambiri kuposa annealing, ndipo n'zovuta kuchita kudula processing, kotero annealing wathunthu ndi Nthawi zambiri amagwiritsidwa ntchito kuchepetsa Kuuma komanso kuwongolera makina.

4. Mpweya wambiri wa carbon kapena zitsulo zokhala ndi mpweya> 0,75% ya chitoliro chozizira chokoka chosasunthika nthawi zambiri chimatenga spheroidizing annealing ngati chithandizo choyambirira cha kutentha. Ngati pali simenti yachiwiri ya meshed, iyenera kusinthidwa kaye. Annealing ndi njira yochizira kutentha yomwe chitoliro chozizira chokoka chitsulo chosasunthika chimatenthedwa mpaka kutentha koyenera, kusungidwa kwa nthawi inayake, kenako kuzirala pang'onopang'ono. Kuzizira pang'onopang'ono ndi mbali yaikulu ya annealing. Mapaipi achitsulo osasunthika ozizira okokedwa ndi ozizira nthawi zambiri amazizidwa mpaka pansi pa 550 ℃ ndi ng'anjo ndi kuziziritsidwa ndi mpweya. Annealing amagwiritsidwa ntchito kwambiri kutentha mankhwala. Popanga zida, nkhungu kapena mbali zamakina, ndi zina zambiri, nthawi zambiri zimakonzedwa ngati chithandizo choyambirira cha kutentha pambuyo poponya, kupangira ndi kuwotcherera, komanso musanayambe kudula (zaukali) kukonza kuti athetse mavuto ena omwe amayamba chifukwa cha ndondomeko yapitayi. zolakwika, ndikukonzekera maopaleshoni otsatirawa.

Cholinga Chowonjezera:

① Kupititsa patsogolo kapena kuthetsa zolakwika zosiyanasiyana zamapangidwe ndi kupsinjika kotsalira komwe kumachitika chifukwa chachitsulo popanga, kupangira, kugudubuza ndi kuwotcherera, ndikupewa kupindika ndi kusweka kwa chogwiriracho;
② kufewetsa chogwirira ntchito podula;
③ Yenga njere ndikuwongolera kapangidwe kake kuti apititse patsogolo makina a workpiece;
④ Konzekerani bungwe kuti lizitha kutentha komaliza (kuzimitsa, kutentha).
