Mipope yachitsulo yopanda msoko

Mipope yachitsulo yopanda msoko imapangidwa ndi chitsulo chonse, ndipo palibe zitsulo pamwamba. Amatchedwa mapaipi achitsulo opanda msoko. Malinga ndi njira yopanga, mipope yopanda phokoso imagawidwa m'mapaipi otentha, mipope yozizira, mipope yozizira, mipope yowonjezera, mipope ya jacking, ndi zina zotero. mapaipi ooneka bwino. Mapaipi ooneka ngati apadera ali ndi masikweya, oval, makona atatu, hexagon, njere ya vwende, nyenyezi, mapaipi amapiko ndi mawonekedwe ena ambiri ovuta. Kutalika kwakukulu ndi 650mm ndipo m'mimba mwake osachepera 0.3mm. Malinga ndi ntchito zosiyanasiyana, pali mipope yokhuthala ndi mipanda yopyapyala. Mapaipi achitsulo osasunthika amagwiritsidwa ntchito kwambiri ngati mapaipi akubowola mafuta a petroleum, mapaipi ophwanyika amafuta amafuta, mapaipi otenthetsera, mapaipi onyamula, ndi mapaipi achitsulo olondola kwambiri pamagalimoto, mathirakitala, ndi ndege. Chitoliro chachitsulo chopanda ma seam m'mphepete mwa gawo lake. Malinga ndi njira zosiyanasiyana zopangira, zimagawidwa m'mapaipi otentha, mapaipi ozizira ozizira, mipope yozizira, mipope ya extruded, mipope ya jacking, ndi zina zotero, zonse zomwe zili ndi ndondomeko zawo. Zida zikuphatikizapo wamba ndi apamwamba mpweya structural zitsulo (Q215-A ~ Q275-A ndi 10 ~ 50 zitsulo), otsika aloyi zitsulo (09MnV, 16Mn, etc.), aloyi chitsulo, zosapanga dzimbiri asidi zosagwira zitsulo, etc. Malinga kuti agwiritse ntchito, amagawidwa m'magulu onse (omwe amagwiritsidwa ntchito pamadzi, mapaipi a gasi ndi zigawo zamakina, makina) ndi ntchito yapadera (yomwe imagwiritsidwa ntchito popangira ma boilers, kufufuza kwa nthaka, mayendedwe, kukana asidi, etc.). ① Njira yayikulu yopangira chitoliro chachitsulo chosasunthika chotentha (△ Njira yayikulu yoyendera):
Kukonzekera ndi kuyang'anitsitsa chitoliro chopanda kanthu △→ Kutenthetsa chitoliro → Kubowoleza chitoliro → Kugudubuza chitoliro → Kutenthetsanso chitoliro → Kukula (kuchepetsa) → Kuchiza kutentha △ → Kuwongola mapaipi omaliza → Kumaliza → Kuyendera △(Kuyendera kwa benchi) → Kusungirako zinthu

Kukonzekera kosapanda kanthu →Kutola asidi ndi kudzola → Kugudubuza kozizira (kujambula)→ Chithandizo cha kutentha→Kuwongola→Kumaliza→Kuyendera
General mosasokoneka zitsulo chitoliro kupanga ndondomeko akhoza kugawidwa mu zojambula ozizira ndi yotentha anagubuduza. Kapangidwe ka chitoliro chachitsulo chosasunthika chozizira nthawi zambiri chimakhala chovuta kwambiri kuposa kugudubuza kotentha. Chitoliro chopanda kanthu chiyenera kukulungidwa ndi zodzigudubuza zitatu, ndiyeno kuyesa kuyenera kuchitika pambuyo pa extrusion. Ngati palibe kung'ung'udza pamwamba, chitoliro chozungulira chiyenera kudulidwa ndi makina odulira ndikudula mu billet pafupifupi mita imodzi m'litali. Ndiye kulowa annealing ndondomeko. Kusakaniza kuyenera kutsukidwa ndi madzi acidic. Pamene pickling, samalani ngati pali thovu lalikulu pamwamba. Ngati pali thovu lalikulu, zikutanthauza kuti ubwino wa chitoliro chachitsulo sichikugwirizana ndi miyezo yoyenera. Maonekedwe, mapaipi achitsulo osakanizidwa ozizira ndi aafupi kuposa mapaipi achitsulo osasunthika. Kukhuthala kwa khoma la mipope yachitsulo yopanda msoko yozizira nthawi zambiri imakhala yaying'ono kuposa mipope yachitsulo yopanda msoko yotentha, koma pamwamba pake imawoneka yowala kuposa mipope yachitsulo yopanda msoko, ndipo pamwamba pake sivuta kwambiri, ndipo m'mimba mwake mulibe. ma burrs ambiri.
Kutumiza kwa mapaipi achitsulo osasunthika otentha nthawi zambiri amatenthedwa ndikutenthedwa asanaperekedwe. Pambuyo poyang'anitsitsa khalidwe, mapaipi achitsulo osasunthika otentha ayenera kusankhidwa mosamala ndi ogwira ntchito, ndipo pamwamba pake ayenera kuthiridwa mafuta pambuyo poyendera khalidwe, ndikutsatiridwa ndi mayesero angapo ozizira ozizira. Pambuyo pa chithandizo chotentha, kuyezetsa perforation kuyenera kuchitidwa. Ngati m'mimba mwake wa perforation ndi waukulu kwambiri, kuwongola ndi kuwongolera kuyenera kuchitika. Pambuyo kuwongola, chipangizo chotumizira chidzaperekedwa ku chowunikira kuti chizindikire zolakwika, ndipo potsirizira pake chimalembedwa, chokonzedwa mwatsatanetsatane, ndi kuikidwa m'nyumba yosungiramo katundu.
Round chubu billet → kutentha → perforation → katatu-roller oblique rolling, mosalekeza kugudubuza kapena extrusion → kuchotsa chubu → kukula (kapena kuchepetsa m'mimba mwake) → kuzizira → kuwongola → hydraulic pressure test (kapena kuzindikira zolakwika) → chizindikiro → yosungirako Chitoliro chopanda msoko chimapangidwa wa chitsulo ingot kapena olimba chubu billet ndi perforation mu chubu akhakula, ndiyeno amapangidwa ndi otentha kugudubuza, ozizira kugudubuza kapena ozizira kujambula. Mafotokozedwe a chitoliro chopanda chitsulo chopanda msoko amawonetsedwa mamilimita akunja awiri * makulidwe a khoma.
M'mimba mwake wakunja kwa chitoliro chosasunthika chotentha nthawi zambiri ndi wamkulu kuposa 32mm, ndipo makulidwe a khoma ndi 2.5-200mm. The awiri akunja ozizira adagulung'undisa zitsulo chitoliro angafikire 6mm, khoma makulidwe angafikire 0.25mm, ndi m'mimba mwake akunja chitoliro woonda-mipanda akhoza kufika 5mm ndi makulidwe khoma ndi zosakwana 0.25mm. Kugudubuza kozizira kumakhala kolondola kwambiri kuposa kugudubuza kotentha.
Nthawi zambiri, mipope yachitsulo yopanda msoko imapangidwa ndi 10, 20, 30, 35, 45 apamwamba kwambiri a carbon steel, 16Mn, 5MnV ndi zitsulo zina zotsika aloyi kapena 40Cr, 30CrMnSi, 45Mn2, 40MnB ndi zitsulo zina za alloy. Kutentha kotentha kapena kuzizira kozizira. Mapaipi opanda msoko opangidwa ndi chitsulo chochepa cha carbon monga 10 ndi 20 amagwiritsidwa ntchito makamaka poperekera madzimadzi. Mapaipi opanda msoko opangidwa ndi chitsulo chapakati cha kaboni monga 45 ndi 40Cr amagwiritsidwa ntchito popanga zida zamakina, monga mbali zonyamula katundu zamagalimoto ndi mathirakitala. Nthawi zambiri, mipope yachitsulo yopanda msoko iyenera kuwonetsetsa kulimba komanso kuyesa kosalala. Mipope yachitsulo yotentha kwambiri imaperekedwa m'madera otentha kapena otentha; mapaipi azitsulo ozizira ozizira amaperekedwa m'madera otentha.
Kuthamanga kotentha, monga momwe dzinalo limatanthawuzira, kumakhala ndi kutentha kwakukulu kwa chidutswa chokulungidwa, kotero kuti kukana kwa deformation kumakhala kochepa ndipo kuchuluka kwakukulu kwa deformation kungapezeke. Kutengera kugudubuza mbale zachitsulo monga chitsanzo, makulidwe a billet mosalekeza nthawi zambiri amakhala pafupifupi 230mm, ndipo pambuyo pakugudubuza movutikira ndikumaliza, makulidwe omaliza ndi 1 ~ 20mm. Pa nthawi yomweyo, chifukwa yaing'ono m'lifupi ndi makulidwe chiŵerengero cha mbale zitsulo, amiyeso yolondola zofunika ndi otsika, ndipo si zophweka kukhala mbale mawonekedwe mavuto, makamaka kulamulira convexity. Kwa iwo omwe ali ndi zofunikira za bungwe, nthawi zambiri zimatheka kudzera mukugudubuzika koyendetsedwa ndi kuzizira koyendetsedwa, ndiko kuti, kuwongolera kutentha koyambira komanso kutentha komaliza kwa kugudubuza komaliza. Round chubu billet → kutentha → kuboola → mutu → annealing → pickling → kudzola mafuta (copper plating) → maulendo angapo a zojambula zozizira (kuzizira) → billet chubu → kutentha kutentha → kuwongola → kuyesa kuthamanga kwa madzi (kuzindikira zolakwika) → chizindikiro → kusunga.
