Tsarin maganin zafi – normalizing

Normalizing, wanda kuma aka sani da al’ada, wani tsari ne na maganin zafi na ƙarfe wanda aikin aikin yana mai tsanani zuwa 30 ~ 50 ° C sama da Ac3 ko Accm, kuma bayan an riƙe shi na wani lokaci, ana fitar da shi daga cikin tanderun kuma sanyaya da ruwa. , fesa ko busa. Bambanci tsakanin daidaitawa da annealing shi ne cewa yanayin sanyaya na daidaitawa yana da sauri fiye da na annealing, don haka tsarin daidaitawa ya fi kyau fiye da tsarin annealing, kuma an inganta kayan aikin injiniya. Bugu da kari, da waje sanyaya na normalizing tanderu ba ya mamaye kayan aiki, da yawan aiki yana da girma. Sabili da haka, ana amfani da al’ada kamar yadda zai yiwu don maye gurbin annealing a cikin samarwa.

Babban wuraren aikace-aikacen al’ada sune: ① Don ƙananan ƙarfe na carbon, taurin bayan al’ada ya dan kadan fiye da na annealing, kuma taurin ya fi kyau, wanda za’a iya amfani dashi azaman pretreatment don yankan. ②Don matsakaicin ƙarfe na carbon, ana iya amfani da shi azaman maganin zafi na ƙarshe maimakon quenching da jiyya na zafin rai, ko azaman magani na shirye-shirye kafin quenching saman ta hanyar dumama shigar. ③Ana amfani da ƙarfe na kayan aiki, ƙarfe mai ɗaukar nauyi, ƙarfe na ƙarfe, da dai sauransu, yana iya rage ko hana samuwar carbide cibiyar sadarwa, don samun kyakkyawan tsarin da ake buƙata don spheroidizing annealing. ④ Don simintin ƙarfe na ƙarfe, yana iya daidaita tsarin simintin simintin gyare-gyare da haɓaka aikin injin. ⑤ Don manyan ƙirƙira, ana iya amfani da shi azaman maganin zafi na ƙarshe don guje wa babban yanayin fashe yayin kashewa. ⑥An yi amfani da shi don ductile baƙin ƙarfe don inganta taurin, ƙarfi da juriya, kamar don kera mahimman sassa kamar crankshafts da igiyoyi masu haɗawa na motoci, tarakta da injunan diesel. ⑦ Daya normalizing kafin spheroidizing annealing na hypereutectoid karfe iya kawar da reticulated cementite don tabbatar da cewa duk cementite ne spheroidized a lokacin spheroidizing annealing.
