Carbon Steel Seamless Steel Tube - Gulu la Royal

1. Kugudubuzika kotentha (chitoliro chopanda chitsulo chosasunthika) : chubu chozungulira chilibe kanthu → Kutenthetsa → kuthirira → kugudubuza kotalikirana katatu, kugudubuza kosalekeza kapena kutulutsa → kuvula → kukula (kapena kuchepetsa) → kuzirala → kuwongola → kuyesa kwa hydrostatic (kapena kuyang'anira) → kulemba → kusungirako
Zopangira zopangira chubu chosasinthika ndi chubu chozungulira, chozungulira chubu chozungulira chimadulidwa ndikukonzedwa ndi makina odulira omwe amakula pafupifupi 1 mita opanda kanthu, ndikutumizidwa kung'anjo ndi kutentha kwa lamba wotumizira. Billet amadyetsedwa mu ng'anjo ndikutenthedwa mpaka pafupifupi madigiri 1200 Celsius. Mafutawa ndi hydrogen kapena acetylene. Kuwongolera kutentha mu ng'anjo ndilo vuto lalikulu. Pambuyo pozungulira chubu billet kutuluka, ndi perforated ndi nkhonya kuthamanga. Kawirikawiri, perforator yodziwika kwambiri ndi conical roll perforator. Perforator yamtunduwu imakhala ndi magwiridwe antchito apamwamba, mtundu wabwino wazinthu, kuchuluka kwa perforating m'mimba mwake ndipo imatha kuvala zitsulo zosiyanasiyana. Pambuyo pobowola, chozungulira chubu billet amagubuduzidwa motsatizana ndi atatu otalikirana okwera, akugudubuza mosalekeza kapena extrusion. Pambuyo pa extrusion, chitolirocho chiyenera kuchotsedwa kuti chiwonjezeke. Caliper imazungulira mumluza wachitsulo kudzera pakubowola kowoneka bwino kwambiri kuti ibowole mabowo ndikupanga mapaipi achitsulo. The awiri m'mimba mwake wa zitsulo chitoliro anatsimikiza ndi akunja awiri kutalika kwa caliper kubowola pang'ono. Pambuyo poyesa chitoliro chachitsulo, chimalowa munsanja yozizirira ndikuzizidwa ndi kupopera madzi. Pambuyo pozizira chitoliro chachitsulo, chidzawongoledwa.
2. Chitoliro chachitsulo chozizira (chogudubuzika) chosasokonekera: chubu chozungulira chilibe kanthu → kutenthetsa → kubowoleza → mutu → kupukuta → pickling → kudzola mafuta (chophimba chamkuwa) → chojambula chozizira chambiri (chozizira) → chubu chopanda kanthu → chithandizo cha kutentha → kuwongola → kuyesa kwa hydrostatic (kuwunika) → kuyika chizindikiro → kusunga.
Njira yodzigudubuza yojambulira (kugudubuzika) chitoliro chachitsulo chosasunthika ndizovuta kwambiri kuposa chitoliro chotentha (extrusion) chopanda chitsulo chosasunthika. Masitepe atatu oyamba akupanga kwawo ndi ofanana. Kusiyana kwa sitepe yachinayi, chubu chozungulira chopanda kanthu pambuyo kukhomerera, kupita kumutu, annealing. Pambuyo pa annealing, madzi apadera acidic amagwiritsidwa ntchito potola. Pambuyo pa pickling, mafuta amagwiritsidwa ntchito. Izi zimatsatiridwa ndi chithandizo chapadera cha kutentha kwa chubu cha rebillet pambuyo pa kujambula kozizira kambiri (kuzizira kozizira). Pambuyo pa chithandizo cha kutentha, chimawongoledwa.
