Chitoliro chachitsulo chowongoka ndi chitoliro chachitsulo chowotcherera chomwe chimatsutsana ndi chitoliro chachitsulo chozungulira. The kuwotcherera ndondomeko ya mtundu uwu wa zitsulo chitoliro ndi yosavuta, mtengo kuwotcherera ndi otsika, ndipo akhoza kukwaniritsa Mwachangu mkulu pa kupanga, choncho ndi wamba pamsika. Ndipo ndi mankhwala omwe amagwiritsidwa ntchito kwambiri, ndiye ubwino wake ndi wotani?

Chitoliro chachitsulo chamtunduwu chimawotchedwa pogwiritsa ntchito njira yowotcherera yomwe ikufanana ndi njira yotalikirapo ya chitoliro chachitsulo, ndipo imagwiritsidwanso ntchito kwambiri. Kwa m'mimba mwake ndi utali womwewo, kutalika kwa kuwotcherera kwa mipope yachitsulo yowongoka ndi yocheperako, pomwe kutalika kwa mipope yazitsulo zozungulira kumatha kuchulukira kuposa 30%. Chifukwa ndondomeko zifukwa pa kuwotcherera dzuwa, dzuwa ndi otsika ndipo linanena bungwe ndi otsika kwambiri. Koma pamapaipi omwewo opanda kanthu, mipope yowotcherera yozungulira imatha kupangidwa mosiyanasiyana. Mosiyana ndi izi, mipope yachitsulo yowongoka ya msoko sangakwaniritse izi.

Mipope yachitsulo yolunjika imagwiritsidwa ntchito kwambiri pamsika chifukwa cha mawonekedwe awo. Popeza mtengo wa ndondomeko yomwe imagwiritsidwa ntchito panthawi yowotcherera ndi yotsika kwambiri, ndipo njira zopangira zitsulo zopangira zitsulo, extrusion, rolling, ndi kujambula zitsulo zingathe kupangidwa, ndipo zomwe zimatchulidwanso ndizotsimikizika, zimapereka ntchito zosiyanasiyana. kuthekera. M'dziko lathu, mafakitale a petrochemical, mafakitale opanga madzi, zomangamanga zamatawuni, zomangamanga zamagetsi, ndi zina zonse zimafunikira mapaipi achitsulo owongoka.

Msika wowongoka wowongoka wamagetsi wowotcherera zitsulo zachitsulo wakhala mu khola lofooka kapena ngakhale kugwa, ndipo kutsika kumakhala kovuta kusintha. Zikumveka kuti ngakhale kuti tsopano ndi chikhalidwe pachimake nyengo kudyedwa mu msika zitsulo, kunsi kwa mtsinje ndi otsiriza kufunika n'kovuta kwambiri kumasula, ndi mphamvu mowa wa mowongoka msoko magetsi welded mipope zitsulo ndi ofooka, chifukwa chosowa thandizo yabwino. zinthu zamitengo. Ndikufika kwaposachedwa kwazinthu zatsopano pamsika, chodabwitsa cha mayendedwe osagwirizana m'malo ena chatsika pang'ono. Ogulitsa omwe ali ndi katundu wokwanira akuyang'anabe kwambiri zotumiza, pomwe amalonda ambiri omwe ali ndi zinthu zochepa amasankha kudikirira ndikuwona zomwe zikuchitika. Mwamwayi, zolimba panopa za liquidity mu mowongoka msoko magetsi welded zitsulo chitoliro msika si mkulu, ndipo komabe sangathe kupanga kupondereza lalikulu pa mtengo azimuth. Pamsika wowongoka wowongoka wamagetsi wowotcherera chitoliro chachitsulo, momwe mtengo umakhalira uyenera kubwereranso pamlingo wofunikira. Poganizira kuti malonda aposachedwa amsika akadali odekha, ndikuwopa kuti pali chiwopsezo chamitengo, koma kukula kwake sikudzakhala kwakukulu.
