Billet yomwe imagwiritsidwa ntchito popanga mapaipi achitsulo imatchedwa chubu billet. Nthawi zambiri chitsulo chapamwamba (kapena aloyi) cholimba chozungulira chimagwiritsidwa ntchito ngati chubu billet. Malingana ndi njira zosiyanasiyana zopangira, machubu opanda phokoso ali ndi mapepala opangidwa ndi zitsulo zachitsulo, mapepala opitirirabe oponyedwa, mapepala opangira mapepala, mapepala opukutidwa ndi mapepala opangidwa ndi centrifugally. chubu billet ndi yofunika kwambiri.

Nthawi zambiri, chubu chopanda kanthu chimatanthawuza kuzungulira chubu billet. Kukula kwa chubu chozungulira billet kumayimiridwa ndi mainchesi azitsulo zolimba zozungulira. Kukonzekera kwa Tube billet kumaphatikizapo kusankha mtundu wa chubu billet ndi mawonekedwe, kapangidwe ka mankhwala ndi kuyang'anira kapangidwe kake, kuyang'anira zolakwika ndi kuyeretsa, kudula, kuyika pakati, etc.
Kupanga kwa seamless steel chubu billet ndi motere:

Kupanga Ironmaking - Kupanga Zitsulo - Open Hearth Steel (kapena Chitsulo cha Ng'anjo Yamagetsi ndi Oxygen Blowing Converter Steel) - Ingot - Billeting - Rolled Round Bar - Tube Billet

A) Gulu la zitsulo zopanda msoko

The seamless zitsulo chubu billet akhoza m'gulu malinga ndi njira processing, mankhwala zikuchokera, kupanga njira, mikhalidwe ntchito, etc. chubu chitsulo.
Mwachitsanzo, malinga ndi njira ya mankhwala, akhoza kugawidwa mu ng'anjo magetsi zitsulo chitoliro billet, Converter zitsulo chitoliro billet ndi electroslag zitsulo chitoliro billet; molingana ndi njira yopangira, imatha kugawidwa mu ingot yachitsulo, chitoliro chopitilira chitoliro, chitoliro chonyezimira, chitoliro chopindika ndi chubu chapakati. Malinga ndi mankhwala zikuchokera, akhoza kugawidwa mu mpweya zitsulo chitoliro billet, aloyi zitsulo chitoliro billet, zosapanga dzimbiri chitoliro billet ndi dzimbiri zosagwira aloyi chitoliro billet; Kubowola ndi kubowola machubu a geological, ma tubu amtundu wa feteleza, mabaluti okhala ndi machubu, ndi zina zapadera zamachubu.

B) Kusankha zitsulo zamachubu opanda msoko

Kusankhidwa kwa zitsulo zazitsulo zopanda zitsulo kumaphatikizapo kusankha magiredi achitsulo, ndondomeko, njira zosungunulira ndi njira zopangira.
Sankhani magiredi achitsulo, njira zopangira ndi kupanga njira molingana ndi miyezo yazinthu kapena kuyitanitsa zinthu zaukadaulo. Kusankhidwa kwa kukula kwa billet kumachokera pakupeza kukula kwa billet kofananira mu tebulo lopukutira molingana ndi kukula kwa chitoliro chachitsulo.

Nthawi zambiri, mphero zazitsulo zopanda msoko zimagwiritsa ntchito chitsulo chosinthira chosinthira kapena chitsulo cha ng'anjo yamagetsi popitilira kuponyera ma billets ozungulira.
Pamene kalasi yachitsulo kapena ndondomeko sizingathe kuponyedwa mosalekeza, chitsulo chosungunuka kapena centrifugal casting chimapangidwa kukhala billet yozungulira. Pamene kukula kwa chubu chopanda kanthu sikungakwaniritse zofunikira za chiŵerengero cha kuponderezana, chubu chokulirapo chopanda kanthu chingasankhidwe ndi kukulungidwa kapena kupangidwa kuti chikhale chopanda kanthu chomwe chimakwaniritsa zofunikira za kukula. Mawerengedwe a chiŵerengero cha psinjika ndi motere: K = F, 1F pamene K ndi chiŵerengero cha kuponderezana; F——gawo lopanda kanthu la chubu lopanda kanthu, mm; F——gawo lapakati la chitoliro chachitsulo, mm.

Pakakhala zofunika kwambiri pakufanana kwa chubu chopanda kanthu, zomwe zili mkati kapena gasi, chubu chopanda kanthu chomwe chimasungunuka ndi electroslag kapena vacuum degassing ng'anjo imagwiritsidwa ntchito.
