Annealing tsari ne na maganin zafi don bututu masu waldaran bakin karfe.Manufarsa ita ce kawar da saura danniya, daidaita girma, da rage halin nakasa da fasa.
Menene annealing na 2205 bakin karfe bututu?
Tare da bututun da aka samar ta hanyar aikin sanyi, hazo carbide, lahani na lattice, da tsarin da bai dace ba da abun da ke ciki zai haifar da juriya na lalata bakin karfe don raguwa.A wannan lokacin, ana buƙatar magani na annealing (ko maganin mafita).
Me yasa bututun bakin karfe 2205 aka rufe?
Rage taurin karfe kuma inganta filastik don sauƙaƙe yankewa da sarrafa nakasar sanyi
Tace hatsi, daidaita tsarin karfe da abun da ke ciki, inganta kaddarorin karfe ko shirya don maganin zafi na gaba
Kawar da ragowar damuwa na ciki a cikin karfe don hana lalacewa da tsagewa.
2205 bakin karfe tube annealing tsari
A cikin samarwa, ana amfani da tsari na annealing sosai.Dangane da daban-daban dalilai na annealing da ake bukata ta workpiece, akwai daban-daban annealing tsari bayani dalla-dalla, da aka saba amfani da su ne danniya taimako annealing, cikakken annealing da spheroidizing annealing.
Danniya taimako annealing.Kayan aiki na yau da kullun don sauƙaƙe damuwa na bututun ƙarfe shine ci gaba da murhun murhun wuta mai haske don bututun ƙarfe, wanda shine nau'in murfi mai ƙyalli mai haske.Tushen iskar gas mai kariya yana ɗaukar tanderun bazuwar ammonia kuma an sanye shi da na'urar tsarkakewa. Hangao Tech (Mashin ɗin SEKO) ya aiwatar da canjin tsarin wutar lantarki, yana kawar da hanyar isar da bel ɗin raga da maye gurbin shi tare da ci gaba da isar da abin nadi guda ɗaya akan layi.Kayan aiki yana da halaye na ci-gaba iko, ban mamaki makamashi ceto, m kiyayewa, da dai sauransu The dumama yankin na dukan line rungumi dabi'ar PID atomatik Multi-zone zafin jiki kula.Bakin karfe bututu zafi-bi ta hanyar mu zafi kiyayewa bakin karfe bututu mai haske annealing makera rage nakasawa da kuma tabbatar da elpticity na bututu.
A bakin karfe tube a ko'ina shirya a kan ciyar tara, aika zuwa annealing tanderu ta hanyar conveyor bel, mai tsanani zuwa 1050-1080 ℃ a karkashin kariya daga wani controlable yanayi, sa'an nan kuma kiyaye na wani ɗan gajeren lokaci, duk carbides iya. a narkar da a cikin annealing tanderu.A cikin tsarin austenite, sa'an nan kuma da sauri sanyaya zuwa ƙasa da 350 ° C, za a iya samun ingantaccen bayani mai ƙarfi, wato, tsari na unidirectional austenite, za a iya samu.
Cikakkun ɓarna.Ana amfani da shi don tace ƙaƙƙarfan tsari mai zafi tare da ƙarancin kayan inji bayan simintin gyare-gyare, ƙirƙira da walda na matsakaici da ƙananan ƙarfe na carbon.Zafin aikin aikin zuwa zafin jiki na 30-50 ° C sama da zafin jiki wanda duk ferrite ke canzawa zuwa austenite, riƙe na ɗan lokaci, sannan a hankali kwantar da tanderun.A lokacin aikin sanyaya, austenite ya sake canzawa, wanda zai iya sa tsarin karfe ya zama bakin ciki..
Spheroidizing Annealing.Ana amfani da shi don rage babban taurin kayan aiki da ƙarfe na ƙarfe bayan ƙirƙira.The workpiece ne mai tsanani zuwa 20-40 ° C sama da zafin jiki a wanda karfe fara samar da austenite, sa'an nan kuma sannu a hankali sanyaya bayan zafi adana.A lokacin aikin sanyaya, siminti na lamellar a cikin pearlite ya zama mai siffar zobe, don haka rage taurin.
