Kupisa-yakakungurutswa yesimbi isina musono pombi kubva pachubhu kuenda kuchigadzirwa kazhinji inoda kudziya mbiri, iyo yakaboora chubhu isati yatanga uye mushure mekudziya uye kukungurutsa dhayamita yepombi isina chinhu pane yakapihwa pre-kudziisa;kugadzirwa kwechando-yakakungurutswa (kudhonza) apo pombi inoda kushandiswa kwepakati annealing kubvisa kushushikana kwakasara;simbi kune zvimwe zvakakosha zvinodiwa, kuitira kuvandudza michina yesimbi pombi nekuvandudza kurongeka uye maitiro ekuita, asiwo kupisa kwayo kurapwa.Common chubhu (pombi) kudziyisa chubhu kukanganisa kusaenzana kudziyisa, oxidation, decarbonization, kupisa makatsemuka, overheating, over-kupisa.

Inopisa pamberi perforated chubhu, uye chinangwa chayo ndechekuvandudza ductility;kuderedza deformation resistance simbi;kupa yakanaka microstructure iri rolling.Ikoko annular furnace chubhu choto, reheating choto, yakarereka yekupisa mavira uye mota yepasi pevira.Tichifunga kushomeka kwepombi dhayamita isati yatangazve kupisa, iyo ine chinangwa chekuwedzera tembiricha yechubhu uye kushomeka kweyunifomu uye kuvandudza ductility yesimbi, kudzora microstructure yayo, kugadzira mamiriro akanaka epombi saizi uye kuve nechokwadi chemichina yesimbi.Common type reheating furnace stepping furnace, continuous roller hearth reheating furnace, the fire hearth oblique, inductive reheating furnace.Cold-yakakungurutswa (dhonza) reheating kuomesa kunyanya kubvisa, kuderedza deformation kuramba.Yakajairika annealing choto inonyanya kushandiswa mukupisa moto, mota yepasi choto, inoenderera roller yemoto choto.Mukugadzirwa kwemachubhu esimbi asina musono, annular vira uye reheating furnace parizvino ndiyo inonyanya kushandiswa;electric induction furnace iri kugadzirwawo;yakarerekera moto yekupisa choto nekuti mhando yacho haina kukwirira, inobata-simba uye inowanzo bviswa.Inoenderera mberi roller hearth furnace inonyanya kushandiswa mukutonhora-yakakunguruka (kudhonza) kupisa kwekupisa kwesimbi;cheni chemota chepasi chakakodzera mabhechi madiki, kupisa kupisa nguva yakareba kupisa uye insulation gobvu-walled alloy simbi pombi;inodzivirira gasi inoenderera mberi roller yemoto yevira inonyanya kushandiswa musimbi pamusoro inoda kupisa kurapwa uye inotonhora yakapera simbi isina oxidation (kudhonza) panguva yekunhonga maitiro annealing.
