Inkqubo ephambili yokuvelisa umbhobho woxinzelelo oluphezulu: ukufudumeza kwe-billet, ityhubhu ene-perforated, ukwandiswa kombhobho.

Ukuqengqeleka kombhobho woxinzelelo oluphezulu, ubungakanani bombhobho kunye nokunciphisa, ukugqiba kunye nombhobho wokupholisa okanye indlela yokuvelisa inokuthiwa Ibillet yokufudumeza iqhina lobushushu lokuchola elibandayo elitsalwa yikhabhoni elitshisayo lokusika intloko yokutshiza umqulu ogqityiweyo ukupakisha uhlobo olunye lombhobho wentsimbi ongenamthungo ophawulwe kuloo nto: Ubuninzi bezitendi eziqengqelekayo ezineerolo ukuya kwicala eliqengqelekayo lolungelelwaniso olwahlukeneyo oluqhubekayo lwe-mandrel mill eqhubekayo, kumgca wokwenza umbhobho wentsimbi ongenamthungo wokuqengqeleka emva kokuqengqeleka kombhobho ojikelezayo emva kokuqengqeleka kwindawo eninzi, ngokweziphumo zomlinganiselo, kancinane ukulawula izikhundla zeziphelo ezichaphazelekayo shaft mandrel lokusila isiseko sokugqiba ukuqengqeleka rolling, ngoko udonga olungalinganiyo ubukhulu ukuya ubuncinane.Ngokuqhelekileyo umbhobho we-alloy> ityhubhu ye-alloy> ityhubhu ye-alloy> umbhobho we-alloy ophezulu ongenamthungo ekubhekiselwe kuwo yintsimbi eqhelekileyo yekhabhoni, intsimbi yekhabhoni ephezulu, intsimbi yealloy kunye nentsimbi eqhelekileyo ephantsi-ingxubevange yolwakhiwo lokwenziwa kombhobho wokuthutha ulwelo okanye ubume bemveliso, ukusetyenziswa kwenxalenye.Idayamitha yombhobho woxinzelelo oluphezulu kunye nobukhulu bodonga obukhoyo, kukho iintlobo ngeentlobo zobunzima bodonga kwidayamitha yangaphandle efanayo, uluhlu olukhulu loxinzelelo lombhobho oluphezulu.Ngokuqhelekileyo ubude bentsimbi, ityhubhu eshushu-eshushu 3-12.5m, umbhobho obandayo (ogqityiweyo) ngu-1.5-9m.
