Nkhani - Njira Yopangira Chitoliro cha Chitsulo cha Ductile: Njira Yolimba Yoponya Mapaipi Apamwamba

Popanga mafakitale amakono, mapaipi achitsulo a ductile amagwiritsidwa ntchito kwambiri popereka madzi, ngalande, kufalitsa gasi ndi magawo ena chifukwa cha makina awo abwino kwambiri komanso kukana dzimbiri. Pofuna kuonetsetsa kudalirika kwapamwamba komanso kudalirika kwa mapaipi achitsulo a ductile, kupanga kwawo kuyenera kuyendetsedwa mosamalitsa komanso kukonzedwa bwino. Kuchokera pakukonzekera ndi kuphatikizika kwachitsulo chosungunula, kuponyera pakati, kutsekereza, ndi kumaliza njira monga kupopera mbewu mankhwalawa zinki, kugaya, kuyezetsa kuthamanga kwa hydraulic, kuyika simenti ndi kupopera phula, ulalo uliwonse ndi wofunikira. Nkhaniyi ifotokoza za kupanga kwaDuctile Cast Iron Pipemwatsatanetsatane, ndikuwonetsa momwe mungawonetsere kuti chitoliro chilichonse chikhoza kukwaniritsa miyezo yapadziko lonse ndi zofunikira zenizeni zogwiritsira ntchito pogwiritsa ntchito kasamalidwe ka sayansi ndi njira zamakono zamakono, ndikupereka zitsimikizo zodalirika za zomangamanga za ntchito zosiyanasiyana zaumisiri.

1. Kukonzekera kwa Chitsulo Chosungunuka
Kukonzekera kwa Iron Molten ndi Spheroidization: Sankhani chitsulo chamtengo wapatali choponyera nkhumba ngati zopangira, monga chitsulo chapamwamba cha ductile casting pig iron, chomwe chili ndi mawonekedwe a low P, low S, ndi low Ti. Malinga ndi mafotokozedwe a m'mimba mwake wa chitoliro kuti apangidwe, zida zofananira zimawonjezedwa kung'anjo yamagetsi yamafupipafupi, yomwe imasintha chitsulo chosungunula ndikuchitenthetsa ndi kutentha komwe kumafunikira ndi ndondomekoyi, kenako ndikuwonjezera spheroidizing wothandizira spheroidization.
Hot Iron Quality Control: Pokonzekera chitsulo chosungunula, ubwino ndi kutentha kwa ulalo uliwonse zimayendetsedwa mosamalitsa. Ng'anjo iliyonse ndi thumba lililonse lachitsulo chosungunuka ziyenera kufufuzidwa ndi spectrometer yowerengera molunjika kuti zitsimikizire kuti chitsulo chosungunuka chikukwaniritsa zofunikira zoponyera.

2. Centrifugal Casting
Madzi utakhazikika Metal Mold Centrifuge Casting: Madzi utakhazikika zitsulo nkhungu centrifuge ntchito kuponyera. Kutentha kwambiri kwachitsulo chosungunuka kumatsanuliridwa mosalekeza mu nkhungu ya chitoliro chothamanga kwambiri. Pansi pa mphamvu ya centrifugal, chitsulo chosungunula chimagawidwa mofanana pakhoma lamkati la nkhungu ya chitoliro, ndipo chitsulo chosungunuka chimalimba mofulumira ndi kuzizira kwa madzi kuti apange chitoliro chachitsulo cha ductile. Kuponya kukamalizidwa, chitolirocho chimawunikidwa nthawi yomweyo ndikuyezedwa ngati pali zolakwika kuti chitoliro chilichonse chiwoneke bwino.
Chithandizo cha Annealing: WojambulaChubu chachitsulondiye amaikidwa mu ng'anjo annealing kwa annealing mankhwala kuthetsa nkhawa mkati kwaiye pa ndondomeko kuponyera ndi kusintha metallographic dongosolo ndi katundu makina chitoliro. .
Kuyesa Magwiridwe: Pambuyo pa annealing, chitoliro chachitsulo cha ductile chimayang'aniridwa ndi mayesero okhwima okhwima, kuphatikizapo kuyesa kwa indentation, kuyesa kwa maonekedwe, kuyesa kwa flattening, kuyesa kwamphamvu, kuyesa kuuma, kuyesa kwa metallographic, ndi zina zotero.

3. Kumaliza
Kupopera Zinc: Chitoliro chachitsulo cha ductile chimagwiritsidwa ntchito ndi zinki pogwiritsa ntchito makina opopera amagetsi othamanga kwambiri. Zinc wosanjikiza akhoza kupanga filimu zoteteza pamwamba pa chitoliro kumapangitsanso dzimbiri kukana chitoliro. .
Kupera: WoyenereraChipo cha Ductile Iron Drainageamatumizidwa ku siteshoni yachitatu yopera kuti akawonedwe, ndipo socket, spigot ndi khoma lamkati la chitoliro chilichonse amapukutidwa ndi kutsukidwa kuti atsimikizire kusalala ndi kutha kwa chitoliro ndi kusindikizidwa kwa mawonekedwe.
Kuyesedwa kwa Hydrostatic: Mapaipi okonzedwa amayesedwa ndi hydrostatic test, ndipo kuthamanga kwa mayeso ndi 10kg/cm² kuposa muyezo wapadziko lonse wa ISO2531 ndi muyezo waku Europe, kuti zitsimikizire kuti mapaipi amatha kupirira kukakamiza kokwanira kwamkati ndikukwaniritsa zofunikira pakugwiritsa ntchito kwenikweni. .
Simenti Lining: Khoma lamkati la chitoliro limakutidwa ndi simenti ndi makina awiri a simenti. Tondo la simenti lomwe limagwiritsidwa ntchito layang'aniridwa mosamalitsa komanso kuwongolera chiŵerengero. Njira yonse yokutira imayang'aniridwa ndi kompyuta kuti zitsimikizire kufanana kwabwino komanso kukhazikika kwazitsulo za simenti. Mapaipi opangidwa ndi simenti amachiritsidwa monga momwe amafunikira kuti akhazikitse bwino mzere wa simenti. .
Kupopera kwa Asphalt: Mapaipi ochiritsidwa amayamba kutenthedwa pamwamba, ndiyeno phula amawapopera ndi sprayer ya double station automatic. Kupaka kwa asphalt kumawonjezera mphamvu yoletsa dzimbiri ya mapaipi ndikuwonjezera moyo wautumiki wa mapaipi. .
Kuyanika Komaliza, Kuyika ndi Kusunga: Mapaipi opopera ndi asphalt amayesedwa komaliza. Mapaipi oyenerera okha ndi omwe angapopedwe ndi zizindikiro, kenaka amapakidwa ndi kusungidwa monga momwe amafunira, akudikirira kutumizidwa kumalo osiyanasiyana kuti agwiritsidwe ntchito.
