Forgingsa cikintsarin ƙirƙira, zafi magani ne mafi muhimmanci mahada, zafi magani wajen annealing, normalizing, quenching da tempering hudu asali matakai, fiye da aka sani da karfe zafi magani na "hudu wuta".

daya, karfe maganin zafin wuta - annealing:
1, annealing ne don zafi da workpiece zuwa dace zafin jiki, bisa ga kayan da workpiece size ta yin amfani da daban-daban rike lokaci, sa'an nan jinkirin sanyaya, da manufar shi ne ya sa karfe ciki kungiyar isa ko kusa da ma'auni jihar, don samun. kyakkyawan tsari da aiki da aiki, ko don ƙarin quenching don shirye-shiryen nama.
2, makasudin annealing:

① Don inganta ko kawar da karfe a cikin simintin gyare-gyare, ƙirƙira, mirgina da tsarin walda wanda ya haifar da lahani iri-iri na ƙungiyoyi da damuwa na saura, don hana nakasar kayan aiki, fatattaka.

② Tausasa kayan aikin don yankan.

③ Tace hatsi da inganta tsarin don inganta kayan aikin injiniya na kayan aiki. (4) Shirya don maganin zafi na ƙarshe (quenching, tempering).
Biyu, ƙarfe zafi magani na biyu wuta - normalizing:
1, normalizing ne don zafi da workpiece zuwa dace zafin jiki bayan sanyaya a cikin iska, da sakamakon normalizing ne kama da annealing, amma tsarin ne mafi kyau, sau da yawa amfani da inganta yankan yi na kayan, amma kuma wani lokacin amfani ga wasu sassa. tare da ƙananan buƙatun azaman maganin zafi na ƙarshe.
2, manufar daidaitawa:
① Yana iya kawar da superheated m hatsi tsarin da widnells tsarin na simintin gyaran kafa, ƙirƙira da walda sassa, da kuma banded tsarin a cikin mirgina abu; Gyaran hatsi; Kuma za'a iya amfani dashi azaman maganin zafin jiki kafin quenching.
② Yana iya kawar da cementite na biyu na cibiyar sadarwa, da kuma tsaftace pearlite, ba wai kawai inganta kayan aikin injiniya ba, amma har ma yana taimakawa ga spheroidizing annealing na gaba.
③Za a iya kawar da siminti na kyauta a iyakar hatsi don inganta aikin zane mai zurfi.
Uku, maganin zafi na ƙarfe na wuta ta uku - quenching:
1, quenching ne don zafi da workpiece bayan zafi kiyayewa, a cikin ruwa, mai ko wasu inorganic salts, Organic ruwa bayani da sauran quenching matsakaici sanyaya da sauri. Bayan quenching, karfe ya zama mai wuya, amma a lokaci guda ya zama maras kyau.
2. Manufar kashewa:
① Inganta kayan aikin ƙarfe na kayan ƙarfe ko sassa. Alal misali: inganta taurin da kuma sa juriya na kayan aiki, bearings, da dai sauransu, inganta na roba iyaka na marẽmari, inganta m inji Properties na shaft sassa, da dai sauransu.
②, inganta kayan kaddarorin ko sinadarai na wasu ƙarfe na musamman. Irin su inganta juriya na bakin karfe, ƙara ƙarfin maganadisu na dindindin na ƙarfe na ƙarfe, da dai sauransu.
Hudu, ƙarfe zafi magani na hudu wuta - tempering:
1, tempering domin rage brittleness na karfe, da quench na karfe a wani dace zafin jiki sama da dakin zafin jiki da kuma kasa 710 ℃ na dogon lokaci, sa'an nan sanyaya, wannan tsari ake kira tempering.
2, dalilin fushi:
①, rage danniya na ciki da kuma rage brittleness, akwai mai yawa danniya da brittleness na quenching sassa, irin su ba dace tempering sau da yawa samar da nakasawa har ma da fatattaka.
② Daidaita kayan aikin injiniya na kayan aikin. Bayan quenching, da workpiece yana da high taurin da brittleness. Domin saduwa da daban-daban yi bukatun na daban-daban workpiece, da taurin, ƙarfi, plasticity da taurin za a iya gyara ta tempering.
③, daidaita girman workpiece. Ta hanyar zafi, ana iya daidaita tsarin metallographic don tabbatar da cewa nakasawa ba zai faru ba a cikin tsarin amfani na gaba.
④, inganta yankan yi na wasu gami karfe.
