Chitoliro chopanda msokonezo (GB/T8162-2008) ndi mtundu wa chitoliro chopanda chitsulo chomwe chimagwiritsidwa ntchito popanga zonse komanso makina.Chitoliro chachitsulo chosasunthika chamadzimadzi chimagwira ntchito pamapaipi opanda zitsulo omwe amanyamula madzi.

Kuwonjezera carbon (C) zinthu ndi kuchuluka kwa pakachitsulo (Si) (zambiri zosaposa 0,40%) ndi manganese (Mn) (zambiri zosaposa 0.80%, apamwamba mpaka 1.20%) aloyi zinthu kwa deoxidation, structural mapaipi achitsulo , popanda zinthu zina zowonjezera (kupatula zinthu zotsalira).

Mipope yachitsulo yotereyi iyenera kutsimikizira zonse zomwe zili ndi mankhwala komanso makina.Zomwe zili muzinthu zonyansa za sulfure (S) ndi phosphorous (P) nthawi zambiri zimayendetsedwa pansi pa 0.035%.Ngati ikuyendetsedwa pansi pa 0,030%, imatchedwa chitsulo chapamwamba kwambiri, ndipo "A" iyenera kuwonjezeredwa pambuyo pa kalasi yake, monga 20A;ngati P imayendetsedwa pansipa 0.025% ndipo S ili pansi pa 0.020%, imatchedwa chitoliro chachitsulo chapamwamba kwambiri, ndipo kalasi yake iyenera kutsatiridwa ndi Add "E" kusiyanitsa.Pazinthu zina zotsalira zotsalira zomwe zimabweretsedwa mu mapaipi achitsulo kuchokera kuzinthu zopangira, zomwe zili mu chromium (Cr), faifi tambala (Ni), mkuwa (Cu), ndi zina zambiri zimayendetsedwa ku Cr≤0.25%, Ni≤0.30%, Cu≤ 0.25%.Magiredi ena a manganese (Mn) amafika 1.40%, otchedwa chitsulo cha manganese.

Kusiyana pakati pa chitoliro chopanda msoko ndi chitoliro chosasunthika chamadzimadzi:

Kusiyanitsa kwakukulu pakati pawo ndi chitoliro chopanda chitsulo chosasunthika ndikuti chitoliro chamadzimadzi chosasunthika chimayesedwa ndi hydraulic test m'modzi kapena akupanga, eddy pano ndi maginito kutayikira.Chifukwa chake, pakusankha kokhazikika kwa mapaipi azitsulo azitsulo, mapaipi achitsulo osasunthika sayenera kugwiritsidwa ntchito.Njira yoyimira chitoliro chachitsulo chosasunthika ndi m'mimba mwake, makulidwe a khoma, ndi chitoliro chachitsulo chosakanizidwa ndi mipanda chimagwiritsidwa ntchito makamaka popanga makina, mgodi wamalasha, chitsulo cha hydraulic, ndi zolinga zina.The zakuthupi wandiweyani-mipanda opanda msokonezo chitoliro lagawidwa 10 #, 20 #, 35 #, 45 #, 16Mn, 27SiMn, 12Cr1MoV, 10CrMo910, 15CrMo, 35CrMo ndi zina zotero.

Chitoliro chosapanga dzimbiri chosapanga dzimbiri (GB/T14975-1994) ndi chitoliro chotentha (chowonjezera, chokulitsa) komanso chitoliro chozizira (chogudubuzika) chosasokonekera.

Chifukwa cha njira zosiyanasiyana zopangira, mapaipi achitsulo osasunthika amagawidwa m'mapaipi achitsulo otenthedwa (otuluka) osasunthika ndi mapaipi achitsulo ozizira (okulungidwa) opanda msoko.Machubu ozizira (okulungidwa) amagawidwa m'mitundu iwiri: machubu ozungulira ndi machubu apadera.

Ndondomeko yoyenda mwachidule:
Kugudubuzika kotentha (chitoliro chachitsulo chosakanizidwa chotuluka): chubu chozungulira → kutenthetsa → kubowoleza → kugudubuzika kozungulira katatu, kugudubuzika kosalekeza kapena kutulutsa → kuchotsa machubu → kukula (kapena kuchepetsa m'mimba mwake) → kuzirala → chubu cha billet → kuwongola → Kuyesa kuthamanga kwamadzi (kapena kuzindikira zolakwika) → chizindikiro → kusungirako.

Chitoliro chozizira chokoka (chokulungidwa) chosasunthika chachitsulo: chozungulira chubu billet → kutentha → perforation → mutu → annealing → pickling → kudzola mafuta (kuyika kwa mkuwa) → kujambula kozizira kopitilira muyeso (kugudubuza kozizira) → billet → chithandizo cha kutentha → kuwongola → Mayeso a Hydraulic (cholakwika kuzindikira)→kuyika →kusungira.
