Kuchuluka kwa ntchito ndi mawonekedwe azinthu za chitoliro chachitsulo chosasunthika chozizira

Chitoliro chachitsulo chosasunthika chozizira chokokandi achitoliro chachitsulo chosasunthika chozizira bwinondi kulondola kwapamwamba kwambiri komanso kumaliza kwabwino kwapamwamba pamakina opangidwa ndi zida zama hydraulic.Kusankha chitoliro cholondola chachitsulo chosasinthikaKupanga makina kapena zida zama hydraulic kumatha kupulumutsa nthawi yamakina, kupititsa patsogolo kuchuluka kwa zinthu zomwe zimagwiritsidwa ntchito ndikuwongolera mtundu wazinthu.

Kuti mupeze mapaipi achitsulo osasunthika okhala ndi kukula kochepa komanso mtundu wabwino, kugudubuza kozizira, kujambula kozizira kapena njira zonse ziwiri ziyenera kutengedwa.Kugudubuza kozizira nthawi zambiri kumachitika pa mphero ziwiri-mkulu, ndipo mapaipi achitsulo osasunthika amakulungidwa mu chiphaso cha annular chopangidwa ndi chozungulira chozungulira chozungulira ndi pulagi yokhazikika.Kujambula kozizira nthawi zambiri kumachitika pa makina a 0.5 ~ 100T amodzi kapena makina ozizirira awiri.

2. Chitoliro chachitsulo chosasunthika chozizira chozizira ndi chinthu chomwe chatuluka m'zaka zaposachedwa, makamaka chifukwa dzenje lamkati ndi miyeso ya kunja kwa khoma ili ndi kulolerana kwakukulu ndi roughness.

Makhalidwe achitoliro chozizira (chogudubuzika) chosasokonekera chachitsulo:

1. Zing'onozing'ono zakunja zakunja.2. Kulondola kwakukulu kungagwiritsidwe ntchito popanga magulu ang'onoang'ono 3. Kukhazikika kwapamwamba kwa zinthu zozizira (zokulungidwa) zozizira komanso khalidwe labwino.4. Mtanda wa chitoliro chachitsulo chosasunthika ndizovuta kwambiri.5. Kuchita kwa chitoliro chachitsulo chosasunthika ndipamwamba, ndipo zitsulo zimakhala zowawa kwambiri.Mipope yachitsulo yopanda msoko ya zomangamanga(GB/T8162-2008) ndi mipope zitsulo zopanda msoko zamapangidwe ambiri ndi makina amakina.Ndi mtundu wa chitoliro chachitsulo chosasinthika chomwe chimagawidwa malinga ndi ntchito zake zosiyanasiyana.Kuchuluka kwa ntchito kumaphatikizapo mitundu yonse ya mapaipi achitsulo osasunthika omwe amagwiritsidwa ntchito pazomangamanga ndi makina, komanso kuchuluka kwa mafakitale monga zomangamanga, makina, mayendedwe, ndege, kugwiritsa ntchito mafuta, etc.

Kusiyana kwakukulu pakati pa annealing ndi normalizing:

1. Kuzizira kwa kutentha kwa normalizing kumakhala kofulumira pang'ono kusiyana ndi kutsekemera kwa annealing, ndipo mlingo wa supercooling ndi wapamwamba 2. The microstructure yomwe imapezeka pambuyo pa normalizing imakhala yabwino kwambiri, ndipo mphamvu ndi kuuma ndizokwera kuposa za annealing.

Kusankha annealing ndi normalizing:

1. Normalizing nthawi zambiri amagwiritsidwa ntchito m'malo momangirira mapaipi achitsulo opanda mpweya opanda mpweya wokhala ndi mpweya wosakwana 0.25%.chifukwa

Kuti kuzirala kwachangu, kumatha kuletsa chitoliro chachitsulo chopanda mpweya chopanda mpweya kuti chisasiyanitse m'malire ambewu ndikusamuka katatu kwa carburization Kupititsa patsogolo kuzizira kozizira kwa magawo opondapo;Normalizing akhoza kusintha kuuma zitsulo

Machinability wa mpweya msoko zitsulo chitoliro;Pamene palibe njira ina kutentha mankhwala, normalizing akhoza Yenga mbewu ndi kusintha mphamvu ya otsika mpweya msokonezo chitoliro.

2.Chitoliro chachitsulo chosakanizidwa ndi mpweya wozizira wapakatikatiokhala ndi mpweya wapakati pa 0,25 ndi 0.5% amathanso kusinthidwa ndikukhazikika

M'malo annealing, ngakhale kuuma kwa ozizira-kokedwa msoko zitsulo chitoliro cha sing'anga mpweya zitsulo pafupi malire chapamwamba mpweya zili ndi apamwamba pang'ono pambuyo normalizing High, koma akhoza kudula, ndipo normalizing mtengo ndi otsika ndi zokolola ndi mkulu. .3.Chitoliro chachitsulo chosakanizidwa chozizira chokhala ndi mpweya wapakati pa 0.5 ndi 0.75% chimakhala ndi mpweya wambiri,

Kuuma pambuyo normalizing ndi apamwamba kwambiri kuposa annealing, choncho n'zovuta kuchita kudula, choncho zambiri Gwiritsani annealing wathunthu kuchepetsa kuuma ndi kusintha machinability.

4. Mpweya wambiri wa carbon kapena zitsulo zokhala ndi mpweya wa carbon ＞ 0,75% ya chitoliro chozizira chosakanizidwa ndi chitsulo chosasunthika nthawi zambiri chimatenga mpira Mankhwala a annealing amagwiritsidwa ntchito ngati chithandizo choyambirira cha kutentha.Ngati pali network yachiwiri simenti, iyenera kuchitidwa choyamba Kuchotsa Moto.Annealing ndikutenthetsa chitoliro chachitsulo chosasunthika chokokedwa ndi kuzizira kuti chizizizira bwino ndikuchisunga kwakanthawi, njira yochizira kutentha ndikuzizira pang'onopang'ono.Kuziziritsa pang'onopang'ono ndiye mbali yayikulu yowotchera, ndipo kujambula kozizira komanso kozizira sikuli Nthawi zambiri, chitoliro chachitsulo cha msoko chimakhazikika mpaka pansi pa 550 ℃ mung'anjo.Annealing amagwiritsidwa ntchito kwambiri Chithandizo cha kutentha kwakukulu nthawi zambiri chimagwiritsidwa ntchito monga kukonzekera popanga zida za zida kapena makina opangira kutentha kumakonzedwa pambuyo poponyera, kupukuta ndi kuwotcherera komanso musanadulidwe (zaukali) kuti athetse ndondomeko yapitayi.Zolakwika zina zomwe zimayambitsidwa ndi ndondomekoyi. , ndi kukonzekera ndondomeko yotsatira.

Cholinga cha Annealing: ① kuchepetsa kuuma kwa chitoliro chachitsulo chosasunthika chozizira kuti chithandizire kukonza;② Chotsani kupsinjika kwamitundu yosiyanasiyana kuti mupewe kupindika kwa chitoliro chachitsulo chosasunthika chozizira;③ Yenga mbewu zolimba ndikusintha mawonekedwe amkati Konzekerani chithandizo chomaliza cha kutentha.
