Technologies Key for Cold Drawn Steel Pipe Production

Mapaipi ozizira okokedwandizofala kwambiri m'makampani ndipo ndi mtundu wogwiritsidwa ntchito kwambiri wachitsulo chachitsulo.

Mipope yazitsulo zoziziritsa kuzizira imapangidwa kuchokera ku mipope yotentha yotentha, ndipo kusankha kwa zinthu, mafotokozedwe, ndi khalidwe la mipope yotentha kwambiri zimakhudza mwachindunji zojambulazo komanso ubwino wa mankhwala omalizidwa.Posankha zipangizo, mfundo zotsatirazi ziyenera kukumbukiridwa:

(1) Posankha zida, zida zolimba pang'ono komanso pulasitiki yabwino nthawi zambiri zimasankhidwa ndikuwonetsetsa mphamvu;

(2) Zolemba zazitsulo zazitsulo ziyenera kusankhidwa malinga ndi zomwe zatsirizidwa, kuonetsetsa kuti kutalika kwawo kuli pakati pa 20% ndi 40%;Ngati elongation ndi yaying'ono kwambiri, mphamvu ya pamwamba ya chinthu chomalizidwa sichingatsimikizidwe, ndipo ngati ndi yaikulu kwambiri, zimakhala zovuta kuchita zojambulazo;

(3) Pamwamba pa zinthuzo sayenera kukhala ndi zolakwika zazikulu monga maenje, ming'alu, ming'alu, ming'alu, zipsera, ellipses, etc;

(4) Ndibwino kuti musankhe mapaipi achitsulo omwe atenthedwa ndi kuikidwa kwa 0.5-2a.Ngati nthawiyo ndi yaifupi kwambiri, dzimbiri la pamwamba pa mapaipi achitsulo lidzakhala losazama, ndipo ngati nthawiyo ili yaitali kwambiri, dzimbiri lazitsulo lazitsulo lidzakhala lakuya kwambiri.Izi zingayambitse kusakwanira chisanadze chithandizo cha zitsulo chitoliro pamwamba, potero zimakhudza pamwamba khalidwe la mankhwala yomalizidwa.

Mipope yachitsulo yosasunthika sichingakokedwe panthawi yozizira chifukwa cha kukangana kwakukulu pakati pa pamwamba pa chitoliro chachitsulo ndi nkhungu;Pokhapokha pokonzekera chithandizo, chitoliro chachitsulo chikhoza kuchotsedwa choyamba, ndipo kudzera mu phosphating, saponification, ndi mankhwala ena, filimu yachitsulo yachitsulo imapangidwira mkati ndi kunja kuti muchepetse mikangano pakati pa chitoliro chachitsulo ndi nkhungu. , motero kuonetsetsa kuti zojambulajambula zikuyenda bwino.Pa nthawi yomweyo, chisanadze mankhwala angathenso kuchepetsa kutayika kwa nkhungu, kusintha zokolola ndi ntchito Mwachangu, ndi kupanga pamwamba pa mankhwala kukonzedwa bwino ndi yunifolomu, ndi wabwino kupewa dzimbiri.

Mfundo zotsatirazi ziyenera kuzindikirika pochiza mipope yachitsulo chisanachitike:

(1) Kuyeretsa asidi ndi kuchotsa dzimbiri kuyenera kukhala koyenera.Dzimbiri lomwe silinachotsedwe likapezeka, liyenera kuchotsedwanso.

(2) Pakupanga, kuchuluka kwa yankho la phosphating ndi yankho la saponification liyenera kuyesedwa pafupipafupi kuti zitsimikizire zowonetsa za yankho la phosphating ndi yankho la saponification.Ngati zizindikiro sizikukwaniritsidwa, kusakaniza kwanthawi yake kuyenera kuchitika.

(3) Onetsetsani kwambiri kutentha ndi nthawi yogwiritsira ntchito njira yothetsera mankhwala.

Cold kukopeka mipope amapangidwa ndi kujambula ena mawonekedwe ndi kukula nkhungu pansi pa zochita za mphamvu, ndi dimensional kulondola ndi pamwamba khalidwe nkhungu mwachindunji amakhudza kulondola dimensional ndi khalidwe la yomalizidwa mankhwala.

Mapangidwe a nkhungu ayenera kulabadira zinthu zotsatirazi:

(1) Kutsimikiza kwa kukula kwa nkhungu mkati ndi kunja kuyenera kuganiziranso kuchuluka kwa zinthu zomwe zamalizidwa pambuyo pojambula kuzizira.Nthawi zambiri, zida zokhala ndi kuuma pang'ono ndi kupindika pang'ono zimakhala ndi kachulukidwe kakang'ono, pomwe zida zolimba kwambiri komanso zopindika zazikulu zimakhala ndi kuchuluka kwakukulu;

(2) Pamwamba pa nkhungu iyenera kukhala ndi kufunikira kocheperako, kawirikawiri mlingo umodzi kapena uwiri wocheperapo kuposa mankhwala omalizidwa;

(3) Zomwe zimapangidwa ndi nkhungu zimapangidwa ndi zinthu zamphamvu kwambiri komanso zosavala.

New Gapower Metalndi katswiri wopanga chitoliro chachitsulo, kukula kuchokera ku OD6mm mpaka 273mm, makulidwe amachokera ku 0.5mm mpaka 35mm.Gulu lachitsulo likhoza kukhala ST35 ST37 ST44 ST52 42CRMO4, S45C CK45 SAE4130 SAE4140 SCM440 etc. Takulandirani kasitomala kuti mufunse ndikupita ku fakitale.
