Nkhani - Njira Yopangira Mapaipi Achitsulo Opangidwa ndi Ductile: Njira Yolimba Yopangira Mapaipi Abwino Kwambiri

Mu mafakitale amakono, mapaipi achitsulo chosungunuka amagwiritsidwa ntchito kwambiri popereka madzi, madzi otayira, kufalitsa mpweya ndi zina chifukwa cha mphamvu zawo zabwino kwambiri zamakaniko komanso kukana dzimbiri. Pofuna kuonetsetsa kuti mapaipi achitsulo chosungunuka ndi abwino komanso odalirika, njira yawo yopangira iyenera kuyendetsedwa bwino komanso kukonzedwa bwino. Kuyambira kukonzekera ndi kusungunula chitsulo chosungunuka, mpaka kuponya kwa centrifugal, kuyika, ndi kumaliza monga kupopera zinc, kupukuta, kuyesa kuthamanga kwa hydraulic, simenti ndi kupopera phula, ulalo uliwonse ndi wofunikira. Nkhaniyi ifotokoza njira yopangiraChitoliro cha Ductile Cast Ironmwatsatanetsatane, ndikuwonetsa momwe mungatsimikizire kuti chitoliro chilichonse chikhoza kukwaniritsa miyezo yapadziko lonse lapansi komanso zofunikira zenizeni zogwiritsira ntchito kudzera mu kayendetsedwe ka sayansi ndi njira zapamwamba zaukadaulo, ndikupereka chitsimikizo chodalirika cha zomangamanga pamapulojekiti osiyanasiyana aukadaulo.

1. Kukonzekera Chitsulo Chosungunuka
Kukonzekera Chitsulo Chosungunuka ndi Kusungunuka kwa Spheroid: Sankhani chitsulo cha nkhumba chopangidwa ndi ductile chomwe chili ndi chitsulo cha nkhumba chopangidwa ndi ductile, chomwe chili ndi makhalidwe a P yochepa, S yochepa, ndi Ti yochepa. Malinga ndi zomwe zili mu payipi ya mainchesi yomwe ikufunika kupangidwa, zinthu zoyenera zimawonjezedwa ku ng'anjo yamagetsi yapakatikati, yomwe imasintha chitsulo chosungunuka ndikuchitentha kutentha komwe kumafunika panthawiyo, kenako ndikuwonjezera chothandizira cha spheroidizing kuti chigwiritsidwe ntchito.
Kuwongolera Ubwino wa Chitsulo Chotentha: Pakukonzekera chitsulo chosungunuka, ubwino ndi kutentha kwa cholumikizira chilichonse zimayendetsedwa mosamala. Uvuni uliwonse ndi thumba lililonse la chitsulo chosungunuka ziyenera kufufuzidwa ndi spectrometer yowerengera mwachindunji kuti zitsimikizire kuti chitsulo chosungunukacho chikukwaniritsa zofunikira pakuponya.

2. Kuponya kwa Centrifugal
Kuponya Chitsulo Chozizira ndi Madzi Chotchedwa Centrifuge Casting: Chitsulo chosungunuka chachitsulo choziziritsidwa ndi madzi chimagwiritsidwa ntchito poponya. Chitsulo chosungunuka cha kutentha kwambiri chimathiridwa nthawi zonse mu chitoliro chozungulira cha chitoliro chothamanga kwambiri. Pogwiritsa ntchito mphamvu ya centrifugal, chitsulo chosungunukacho chimagawidwa mofanana pakhoma lamkati la chitoliro cha chitoliro, ndipo chitsulo chosungunukacho chimalimba mwachangu ndi kuzizira kwa madzi kuti chipange chitoliro chachitsulo chosungunuka. Pambuyo poponya, chitolirocho chimayang'aniridwa nthawi yomweyo ndikuyesedwa ngati pali zolakwika pakuponya kuti zitsimikizire mtundu wa chitoliro chilichonse.
Chithandizo cha Annealing: Ochita seweroChubu chachitsuloKenako imayikidwa mu uvuni wothira madzi kuti ichotse kupsinjika kwamkati komwe kumachitika panthawi yothira madzi ndikukonza kapangidwe ka metallographic ndi mawonekedwe a makina a chitolirocho.
Kuyesa Magwiridwe Antchito: Pambuyo poyatsa, chitoliro chachitsulo chodumphadumpha chimayesedwa motsatira njira zosiyanasiyana, kuphatikizapo mayeso olowera, mayeso owoneka, mayeso ophwanyika, mayeso omangirira, mayeso ouma, mayeso a metallographic, ndi zina zotero. Mapaipi omwe sakwaniritsa zofunikira adzachotsedwa ndipo sayenera kulowa mu ndondomeko yotsatira.

Chitoliro chachitsulo chopangidwa ndi ductile

3. Kumaliza
Kupopera ZincChitoliro chachitsulo chosungunuka chimathiridwa ndi zinc pogwiritsa ntchito makina opopera amagetsi amphamvu kwambiri. Zinc wosanjikiza ukhoza kupanga filimu yoteteza pamwamba pa chitoliro kuti chiwonjezeke kukana dzimbiri kwa chitolirocho.
Kupera: WoyenereraChitoliro cha Ductile Iron DrainageAmatumizidwa ku malo opukutira achitatu kuti akawone mawonekedwe ake, ndipo soketi, spigot ndi khoma lamkati la chitoliro chilichonse zimapukutidwa ndikutsukidwa kuti zitsimikizire kuti pamwamba pa chitolirocho ndi potseka mawonekedwe ake.
Mayeso a HydrostaticMapaipi okonzedwa amayesedwa ndi hydrostatic, ndipo kuthamanga kwa mayeso ndi 10kg/cm² kuposa muyezo wapadziko lonse wa ISO2531 ndi muyezo wa ku Europe, kuti zitsimikizire kuti mapaipiwo amatha kupirira kuthamanga kwamkati kokwanira ndikukwaniritsa zofunikira pakukakamizidwa pakugwiritsa ntchito kwenikweni.
Mkati mwa simenti: Khoma lamkati la chitolirocho limakutidwa ndi simenti pogwiritsa ntchito makina olumikizira simenti okhala ndi malo awiri. Chomangira cha simenti chomwe chimagwiritsidwa ntchito chayang'aniridwa bwino komanso kulamulidwa ndi chiŵerengero cha zinthu. Njira yonse yophimba imayendetsedwa ndi kompyuta kuti zitsimikizire kuti chomangira simenti chili bwino komanso chokhazikika. Mapaipi okhala ndi simenti amakonzedwa ngati pakufunika kuti chomangira simenti chikhale cholimba mokwanira.
Kupopera Asphalt: Mapaipi okonzedwa amayamba kutenthedwa pamwamba, kenako phula limapopedwa ndi chopopera chodzipangira chokha chokhala ndi malo awiri. Chophimba cha phula chimawonjezera mphamvu yolimbana ndi dzimbiri ya mapaipi ndikuwonjezera nthawi yogwira ntchito ya mapaipi.
Kuyendera Komaliza, Kulongedza ndi Kusunga: Mapaipi opopera ndi phula amayesedwa komaliza. Mapaipi oyenerera bwino okha ndi omwe angapoperedwe ndi zizindikiro, kenako nkupakidwa ndi kusungidwa momwe akufunira, akudikira kuti atumizidwe kumalo osiyanasiyana kuti akagwiritsidwe ntchito.
