①Kulolera kwakunja
Chitoliro chachitsulo chosasunthika: Njira yopangira yotentha imagwiritsidwa ntchito, ndipo kukula kwake kumamalizidwa pafupifupi 8000C. Kapangidwe kazinthu zopangira, kuzizirira, komanso kuzizira kwa mipukutu ya chitoliro chachitsulo zimakhudza kwambiri m'mimba mwake. Chifukwa chake, kuwongolera m'mimba mwake kumakhala kovuta kulondola komanso kusinthasintha. Zokulirapo.
Chitoliro chachitsulo cha ERW: chimatenga kupendekera kozizira ndikuchepetsa kutsika kwa 0.6%. Kutentha kwa ndondomekoyi kumakhala kosalekeza kutentha, kotero kuti m'mimba mwake kunja kumayendetsedwa molondola ndipo kusinthasintha kumakhala kochepa, komwe kumathandiza kuti ma buckles athetsedwe;

②Kulekerera makulidwe a khoma
Chitoliro chachitsulo chosasunthika: Chopangidwa ndi zitsulo zozungulira zozungulira, kupatuka kwa makulidwe a khoma ndi kwakukulu. Kugudubuzika kotsatira kotentha kumatha kuthetseratu kusalingana kwa khoma, koma pakadali pano, mayunitsi apamwamba kwambiri amatha kuwongolera mkati mwa ± 5 ~ 10% t.
Chitoliro chachitsulo cha ERW: Ma coils otenthedwa ndi otentha amagwiritsidwa ntchito ngati zida zopangira, ndipo kulolerana kwa makulidwe azitsulo zamakono zotenthedwa zimatha kuwongoleredwa mkati mwa 0.05mm.

③Mawonekedwe
Zowonongeka zakunja zakunja zomwe zimagwiritsidwa ntchito m'mapaipi opanda zitsulo sizingathetsedwe kupyolera mu ndondomeko yotentha yotentha. Amatha kupukuta pambuyo pomaliza kumaliza. Njira yozungulira yomwe yatsala pambuyo pobowoleza imatha kuthetsedwa pang'ono panthawi yochepetsera khoma.
Mapaipi achitsulo a ERW amagwiritsa ntchito ma koyilo opiringizika otentha ngati zida. Ubwino wapamtunda wa ma koyilo ndi mawonekedwe apamwamba a mapaipi achitsulo a ERW. Ubwino wa pamwamba wa ma koyilo otenthedwa ndi osavuta kuwongolera komanso ali ndi mawonekedwe apamwamba. Chifukwa chake, mawonekedwe apamwamba a mapaipi achitsulo a ERW ndiabwino kwambiri kuposa mapaipi achitsulo opanda msoko.

④Ovality
Chitoliro chachitsulo chosasunthika: Pogwiritsa ntchito njira yopangira yotentha, kapangidwe kazinthu zopangira, kuziziritsa, komanso kuziziritsa kwa mipukutuyo zonse zimakhudza kwambiri kunja kwa chitoliro chachitsulo. Chifukwa chake, kuwongolera m'mimba mwake kumakhala kovuta kuwongolera molondola, ndipo kusinthasintha kwamitundu ndi kwakukulu.
ERW chitsulo chitoliro: Imapangidwa ndi kupendekeka kozizira, kotero kuti m'mimba mwake yakunja imayendetsedwa molondola ndipo kusinthasintha kwake kumakhala kochepa.

⑤Mayeso olimba
Zizindikiro zogwira ntchito zamapaipi achitsulo opanda msoko ndi mapaipi achitsulo a ERW onse amakwaniritsa miyezo ya API, koma kulimba kwa mapaipi achitsulo osasunthika nthawi zambiri kumakhala kumtunda ndipo pulasitiki imakhala yotsika. Poyerekeza, index ya mphamvu ya mapaipi achitsulo a ERW ndi yabwino kwambiri, ndipo index ya pulasitiki ndi 33.3% kuposa muyezo. , chifukwa chake ndi chakuti ntchito yazitsulo zotentha zotentha, zopangira zitsulo zazitsulo za ERW, zimatsimikiziridwa pogwiritsa ntchito microalloying smelting, kuyeretsa kunja kwa ng'anjo, ndi kuzizira kolamulidwa ndi kugudubuza; mapaipi achitsulo opanda msoko makamaka amadalira njira zowonjezera mpweya wa carbon, zomwe zimapangitsa kuti zikhale zovuta kutsimikizira mphamvu ndi pulasitiki. machesi wololera.

⑥Kuvuta
Zomwe zimapangidwa ndi mapaipi achitsulo a ERW - mazenera otenthedwa, amakhala olondola kwambiri pakuziziritsa komanso kugudubuza panthawi yogubuduza, zomwe zimatha kutsimikizira magwiridwe antchito amtundu uliwonse wa ma coils.

⑦Kukula kwambewu
Zopangira za chitoliro chachitsulo cha ERW - chowotcha chozungulira chowotcha chimapangidwa ndi billet yayikulu komanso yayikulu yosalekeza, yomwe imakhala ndi gawo laling'ono lolimba, lopanda kristalo wa columnar, shrinkage cavity ndi looseness, kupatuka kwakung'ono, komanso wandiweyani. kapangidwe; mu ndondomeko wotsatira anagubuduza Pakati pawo, ntchito ankalamulira kuzirala ndi ankalamulira anagubuduza luso zina kuonetsetsa kuti mbewu kukula kwa zipangizo.

⑧Kugwetsa kukana kuyesa
Chitoliro chachitsulo cha ERW chimadziwika ndi zida zake komanso kupanga chitoliro. Kufanana kwake ndi makulidwe a khoma ndi oval ndi bwino kwambiri kuposa mapaipi achitsulo opanda msoko, chifukwa chachikulu chomwe ntchito yake yotsutsa kugwa ndi yapamwamba kuposa mipope yachitsulo yopanda msoko.

⑨Kuyesa kwamphamvu
Popeza kulimba kwa zinthu zoyambira za mapaipi achitsulo a ERW ndi kuwirikiza kangapo kuposa mapaipi achitsulo opanda msoko, kulimba kwa weld ndiye chinsinsi cha mapaipi achitsulo a ERW. Ndi kulamulira zonyansa zili zopangira, kutalika ndi malangizo a slitting burrs, mawonekedwe a m'mbali anapanga, kuwotcherera ngodya, liwiro kuwotcherera, Kutentha mphamvu, ndi pafupipafupi, kuwotcherera extrusion kuchuluka, wapakatikati pafupipafupi achire kutentha ndi kuya, mpweya. kuzirala gawo kutalika ndi magawo ena ndondomeko kuonetsetsa kuti mphamvu mphamvu ya weld kufika oposa 60% ya zitsulo m'munsi. Ngati kukhathamiritsanso, mphamvu ya weld imatha kuyandikira yachitsulo cha kholo. zipangizo, kuchititsa ntchito mosokonekera.

⑩Kuyesa kuphulika
Mayesero ophulika a mapaipi achitsulo a ERW ndi apamwamba kwambiri kuposa zomwe zimafunikira, makamaka chifukwa cha kufanana kwakukulu kwa makulidwe a khoma ndi yunifolomu yakunja kwa mapaipi achitsulo a ERW.

⑪Kuwongoka
Mipope yachitsulo yosasunthika imapangidwa mu pulasitiki, ndipo ndi wolamulira umodzi (nthawi 3 mpaka 4 wolamulira kuti azigudubuza mosalekeza), kuwongoka kwa mapeto a chitoliro kumakhala kovuta kulamulira;
Mapaipi achitsulo a ERW amakonzedwa mozizira ndipo amawongoka pa intaneti m'kati mwake. Kuphatikiza apo, amachulukitsidwa mopanda malire, kotero kuwongoka kuli bwino.

⑫Kuchuluka kwachitsulo chomwe chimagwiritsidwa ntchito posungira pamamita 10,000 a kanema
Makulidwe a khoma la mipope yachitsulo ya ERW ndi yunifolomu ndipo kulolerana kwa makulidwe ake ndikosavuta, pomwe malire olondola a kusiyana kwa makulidwe a mipope yachitsulo ndi ± 5% t, yomwe nthawi zambiri imayendetsedwa pa ± 5 ~ 10% t. Kuonetsetsa kuti makulidwe ochepera a khoma amatha kukwaniritsa zofunikira komanso magwiridwe antchito, njira yokhayo ndiyowonjezera makulidwe a khoma moyenera. Chifukwa chake, pakuyika zofananira ndi kulemera kwake, mapaipi achitsulo a ERW amakhala otalikirapo 5 mpaka 10% kuposa mipope yachitsulo yopanda msoko, kapena kupitilira apo, zomwe zimachepetsa kugwiritsa ntchito zitsulo pamamita 10,000 a kanema ndi 5 mpaka 10%. Ngakhale pamtengo womwewo, mapaipi achitsulo a ERW amapulumutsa ogwiritsa ntchito 5 mpaka 10% ya ndalama zogulira.

Chidule cha nkhaniyi: Komabe, pakali pano maiko akunyumba ndi akunja akugwiritsabe ntchito zopanda msoko, chifukwa zitsulo zapaipi zazitsulo za ERW zitha kulamulidwa pamtengo wapamwamba kwambiri wa K55. Ngati kalasi yachitsulo ndi yapamwamba, tilibe mphamvu zopanga zoweta. Ponena za msika wamakono wa ERW wachitsulo, zida zopangira ku Japan ndi ukadaulo wopanga zimatha kufikira pamlingo wina wopangira casing, koma zimatha kutulutsa mpaka N80. Ngati mukufuna kupanga P110 kapena apamwamba apamwamba zitsulo, pali panopa malire. Zovuta, kotero chitoliro chachitsulo cha ERW chingagwiritsidwe ntchito ngati wotchi.
