Nthawi zambiri, ang'onoang'ono ndi apakatikati (H400×200 ndi pansi) matabwa a H nthawi zambiri amagwiritsa ntchito masikweya atali ndi makona anayi, ndi okulirapo (H400)×200 ndi pamwamba) Miyendo ya H nthawi zambiri imagwiritsa ntchito mapepala opangidwa ndi mawonekedwe apadera, ndipo mapepala opitilirapo amatha kugwiritsidwa ntchito pamapepala amtundu wa makoswe ndi apadera.Pambuyo kuyeza, billet kuchokera kuponyedwa kosalekeza imayikidwa mu sitepe ndi sitepe (kapena mtundu wa pusher, pali ng'anjo zochepa zomwe zimagwiritsidwa ntchito popanga zitsulo zachigawo) ng'anjo yotentha ndi kutentha mpaka 1200-1250.°C kuti amasulidwe mu ng'anjo.Ambiri mwa ng'anjo zowotchera zoyenda amatengera zowotcha ziwiri zoyatsira moto zomwe zimakonzedwa m'mwamba ndi pansi, zomwe zimatha kupereka kutentha kwabwino kwa ma billets amitundu yosiyanasiyana ndikusunga mafuta.
Billet ikatuluka mu ng'anjo, imayikidwa koyamba ndi 10-25MPa madzi othamanga kwambiri, kenako imatumizidwa ku mphero ya billet kuti igubuduze.Makina osalemba kanthu nthawi zambiri amakhala mphero ya mipukutu iwiri (palinso gitala itatu.mpherokwa chitsulo chaching'ono, koma kuchepa kwa ndondomeko sikungagwirizane ndi bungwe lopanga kupanga), ndipo makina osatsegula amayenera kugubuduzidwa pafupifupi 5 mpaka 13 akudutsa, ndiyeno chidutswa chogubuduzika Chowonadi chotentha chimakhala ndi udindo wodula mbali yosasinthika. mutu, komakumeta ubweya wowulukaakhoza kudula mutu, gawo ndi mchira.Zidutswa zomwe zidakulungidwa pambuyo podula mutu zimatumizidwa ku mphero yomaliza kuti agubuduze.The kutsirizitsa anagubuduza ang'onoang'ono chigawo zitsulo opanga zikuluzikulu zoweta utenga mawonekedwe a anagubuduza mosalekeza, ndi yotsirizira anagubuduza lalikulu-kakulidwe zitsulo gawo ndi kugubuduza reversible.Akamaliza kugudubuza, nthawi zambiri amatumizidwa ku bedi lozizirira kuti akaziziritse, koma palinso magawo omwe amagawika bedi lozizirira lisanakwane kapena kudulidwa pambuyo pa bedi lozizirira.Chifukwa cha kusiyana kwakukulu pakati pa makulidwe a miyendo ndi makulidwe a m'chiuno cha zitsulo zazikuluzikulu-kakulidwe kagawo, ngati ayikidwa lathyathyathya, kuzirala liwiro la m'chiuno ndi miyendo ndi zosagwirizana, kuchititsa mafunde m'chiuno, kotero ofukula. Kuziziritsa kumagwiritsidwa ntchito nthawi zambiri.Komabe, omwe amapanga matabwa ang'onoang'ono a H onse amatengerapoponda mano ozizira mabedi, zomwe zimayikidwa mobisa pachoyikapo.Kugwiritsa ntchito mabedi oziziritsira dzino sikungangochepetsa zolakwika zomwe zimayambitsidwa ndi makina onyamula unyolo woyambirira, komanso kuwongolera kuzirala kwa liwiro lachitsulo mosavuta.The utakhazikika H-mtengo amatumizidwa kwamakina owongolakwa kuwongola.Chifukwa cha gawo lalikulu la matabwa a H-mitengo, makina owongolera a 8-roll, 9-roll kapena 10-roll amagwiritsidwa ntchito kuwongola, ndipo mtunda wautali pakati pa odzigudubuza ukhoza kufika 2200mm.Pambuyo kuwongola, chitsulocho chimatumizidwa kumalo osungiramo magulu kuti apange magulu ndikudikirira kucheka.Pambuyo podulidwa ndi macheka ozizira molingana ndi utali wokhazikika, amatumizidwa ku tebulo loyang'anira kuti ayang'ane kukula kwake, mawonekedwe ake ndi khalidwe lapamwamba, ndiyeno amasanjidwa, amasanjidwa ndi kumangidwa.kutumizidwa kunkhokwe.Pakuti mankhwala osayenera, malinga ndi mtundu wa chilema, lolingana kachiwiri kuwongola, akupera, kuwotcherera kukonza ndi mankhwala ena adzachitidwa, ndiyeno iwo adzalowa lolingana khalidwe anayendera pulogalamu ndiyeno m'gulu yosungirako pambuyo podutsa anayendera.
Pofuna kupititsa patsogolo kagwiritsidwe ntchito ka mphero ndikuchepetsa nthawi yosinthira mpukutu, pafupifupi opanga onse amatengera njira yosinthira mwachangu, ndiko kuti, mipukutu yofunikira pamitundu yotsatira imasonkhanitsidwa pasadakhale popanga.Mukasintha mipukutu, ingotulutsani zoyika zonse zoyambirira ndikuzisintha ndi zida zatsopano zomwe zayikidwa.Chimango chilichonse chimakhala ndi cholumikizira chofulumira, chomwe chimaphatikizapo madzi ozizira, kuthamanga kwa hydraulic, mafuta opyapyala ndi maulalo a mapaipi owuma komanso zida zolumikizira zolumikizira ndodo.Chipangizocho ndi chosavuta komanso chofulumira kusokoneza ndikugwirizanitsa, ndipo nthawi yonse yosintha mpukutu ndi pafupi mphindi 10-20.Malinga ndi mpukutu kusintha zinachitikira zitsulo zazing'ono, lonse mpukutu kusintha nthawi zambiri za 45-70 mphindi.
