Kodi chitoliro chachitsulo cha carbon ndi chitoliro chachitsulo chowotcherera?

Mpweya zitsulo chitoliro si welded zitsulo chitoliro. Mpweya zitsulo chitoliro amatanthauza zinthu zenizeni za chitsulo chitoliro ndi mpweya zitsulo, kutanthauza chitsulo-mpweya aloyi ndi mpweya zili Wc zosakwana 2.11%. Kuphatikiza pa kaboni, nthawi zambiri imakhala ndi silicon, manganese, phosphorous, sulfure ndi zonyansa zina. ndi zina zotsalira zotsalira. Kuphatikiza apo, chitoliro chachitsulo cha kaboni ichi chili ndi ntchito zambiri, zomwe zimagwiritsidwa ntchito pomanga, milatho, njanji, magalimoto, zombo ndi mafakitale osiyanasiyana opanga makina.

Mpweya zitsulo mipope akhoza kugawidwa mu mpweya zitsulo welded mapaipi ndi mpweya zitsulo mipope msokonezo malinga ndi ndondomeko kupanga.

Mpweya wachitsulo welded mapaipi akhoza kugawidwa m'magulu atatu: msoko wowongoka pansi pa madzi arc welded zitsulo mapaipi, mipope zitsulo wozungulira, ndi mipope yowongoka yowongoka kwambiri yowongoka molingana ndi njira yopangira msoko wowotcherera.
Longitudinal welded chitoliro: The weld ali mu mzere wolunjika, choncho amatchedwa molunjika msoko welded chitoliro.
Spiral welded pipe: Msoko wowotcherera uli mu mawonekedwe ozungulira, omwe amatchedwa spiral welding.

Njira zitatu zowotcherera zili ndi ubwino ndi zovuta zake, ndipo zomwe zimagwiritsidwa ntchito zimadalira zomwe zimapangidwira. Carbon steel welded steel pipe ingagwiritsidwe ntchito m'magawo ambiri, monga ntchito zoperekera madzi ndi ngalande, mapulojekiti ophatikizira, mapaipi a zinyalala, kutumiza mafuta ndi gasi, zipilala zamapangidwe ndi ntchito zina. Panopa njira kuwotcherera mpweya zitsulo welded zitsulo chitoliro makamaka iwiri kumbali kumizidwa arc kuwotcherera. Njira yowotcherera iyi imakhala ndi magwiridwe antchito apamwamba, mawonekedwe apamwamba kwambiri komanso malo osalala.

Njira yopanga chitoliro chopanda chitsulo cha Carbon:

Mapaipi achitsulo opanda mpweya amagawidwa m'mitundu iwiri: mapaipi achitsulo otenthedwa (otuluka) osasunthika ndi mapaipi achitsulo ozizira (okulungidwa) opanda msoko chifukwa cha njira zosiyanasiyana zopangira. Machubu ozizira (okulungidwa) amagawidwa m'mitundu iwiri: machubu ozungulira ndi machubu ooneka ngati apadera.

1. Chitoliro chachitsulo chotentha (chotuluka) cha carbon chitsulo chosasokonezeka: chubu chozungulira → kutenthetsa → kuboola → kugudubuza mipukutu itatu, kugudubuza mosalekeza kapena kutulutsa → kuchotsa machubu → kukula (kapena kuchepetsa) → kuzirala → kuwongola → kuyezetsa kupanikizika kwa madzi ( kapena kuzindikira zolakwika) → kuyika chizindikiro → kusungirako

Zopangira zopangira chitoliro chopanda chitsulo cha kaboni ndi chubu chozungulira, ndipo mluza wozungulira wa chubu uyenera kudulidwa ndi makina odulira kuti ukule mabilu atali pafupifupi mita imodzi, ndikupita kung'anjo ndi lamba wotumizira. Billet amadyetsedwa mu ng'anjo kutentha, kutentha ndi pafupifupi 1200 digiri Celsius. Mafutawa ndi hydrogen kapena acetylene. Kuwongolera kutentha mu ng'anjo ndi nkhani yaikulu. Pambuyo pozungulira chubu kuchokera mu ng'anjo, iyenera kubayidwa kupyolera mu kubowola kokakamiza. Nthawi zambiri, woboola wofala kwambiri ndi woboola chulu. Woboola wamtunduwu amakhala ndi magwiridwe antchito apamwamba, mtundu wabwino wazinthu, kukulitsa kwakukulu koboola m'mimba mwake, ndipo amatha kuvala mitundu yosiyanasiyana yazitsulo. Pambuyo kuboola, chozungulira chubu billet imapindidwa motsatizana, kukulungidwa mosalekeza kapena kutulutsa mipukutu itatu. Pambuyo pa extrusion, chubu liyenera kuchotsedwa kuti liyike. Kukula pobowola mothamanga kwambiri ma rotary cone mu billet kupanga chubu. M'mimba mwake mkati mwa chitoliro chachitsulo chimatsimikiziridwa ndi kutalika kwa m'mimba mwake wakunja kwa kubowola kwa makina opangira. Chitoliro chachitsulo chikakula, chimalowa munsanja yozizirira ndipo chimakhazikika ndi kupopera madzi. Chitoliro chachitsulo chikakhazikika, chidzawongoledwa. Pambuyo kuwongola, chitoliro chachitsulo chimatumizidwa ku chowunikira chachitsulo (kapena kuyesa kwa hydraulic) ndi lamba wotumizira kuti azindikire zolakwika zamkati. Ngati pali ming'alu, thovu ndi mavuto ena mkati mwa chitoliro chachitsulo, adzadziwika. Pambuyo pakuwunika kwabwino kwa mapaipi achitsulo, kusankha kozama kwamanja kumafunika. Pambuyo poyang'ana khalidwe la chitoliro chachitsulo, pentani nambala ya siriyo, ndondomeko, nambala ya batch yopanga, etc. ndi utoto. Ndipo adakwezedwa m'nyumba yosungiramo katundu ndi crane.

2. Chitoliro chozizira chokoka (chogudubuzika) chachitsulo cha kaboni chopanda msokonezo: chubu chozungulira chosasoweka →kutenthetsa→kuboola→mutu→kuwotcha→kuwotcha→kuwotcha →kupaka mafuta (kuyika kwa mkuwa)→kujambula kozizira kosiyanasiyana (kugudubuzika kozizira)→chubu chopanda kanthu→mankhwala otentha→ kuwongola → kuyesa kwa hydrostatic (kuzindikira zolakwika) → kuyika → kusunga
