Normalizing mushonga wekupisa unovandudza kuoma kwesimbi. Mushure mekupisa zvinhu zvesimbi kusvika patembiricha ye30-50 ℃ pamusoro petembiricha yeAc3, zvibate kwenguva yakati uye nemhepo zvitonhodze kubva muchoto. Chimiro chikuru ndechekuti mwero wekutonhodza unokurumidza pane kuvharisa asi wakaderera pane kudzima. Munguva ye normalizing, iyo crystalline tsanga dzesimbi inogona kunatswa mune zvishoma inokurumidza kutonhora maitiro, iyo isingangowani simba rinogutsa, asi zvakare inovandudza zvakanyanya kuoma (AKV kukosha) uye inoderedza maitiro ezvimedu kutsemuka Mushure me normalizing, iyo yakazara mechanical properties. yeimwe yakaderera alloy inopisa yakakungurutswa simbi mahwendefa, yakaderera alloy simbi forgings, uye castings inogona kuvandudzwa zvakanyanya, uye kuita kwekucheka kunogonawo kuvandudzwa.
Normalizing inonyanya kushandiswa kune simbi workpieces. Normalizing uye annealing yegeneral simbi yakafanana, asi mwero wekutonhora wakakwira zvishoma uye microstructure yakanaka. Mamwe masimbi ane mwero wakaderera wakakomba wekutonhora anogona kushandura austenite kuita martensite nekutonhodza mumhepo. Mushonga uyu hauna kujaira uye unonzi air cooling quenching. Pane zvinopesana, mamwe mahombe e-cross-section workpieces akagadzirwa nesimbi ane yakanyanya kutonhora kutonhora mwero haakwanise kuwana martensite kunyangwe mushure mekudzima mumvura, uye kudzima kwave pedyo nekujairira. Kuomarara kwesimbi mushure mekudzikamisa kwakakwira kupfuura iyo mushure mekuvhara. Paunenge uchijairika, hazvifanirwe kutonhodza iyo workpiece muchoto senge annealing, iyo inotora nguva pfupi yechoto uye ine yakakwira kugadzirwa. Naizvozvo, mukugadzira, normalizing inowanzo shandiswa pachinzvimbo cheannealing zvakanyanya sezvinobvira. Kune yakaderera-kabhoni simbi ine kabhoni yemukati yakaderera pane 0.25%, kuomarara kunowanikwa mushure mejairika kuri pakati nepakati uye kuri nyore kucheka pane annealing. Normalizing inowanzo shandiswa kucheka uye kugadzirira basa. Kune yepakati kabhoni simbi ine kabhoni yemukati ye0.25-0.5%, normalizing inogonawo kusangana nezvinodiwa zvekucheka kugadzirisa. Kune zvikamu zvisingaremi zvakagadzirwa nemhando iyi yesimbi, normalizing inogonawo kushandiswa seyekupedzisira kupisa kurapwa. Normalizing yakakwira kabhoni chishandiso simbi uye inotakura simbi ndeyekubvisa network carbides muchimiro uye kugadzirira chimiro che periodization annealing.
Iyo yekupedzisira yekupisa kupisa yezvakajairwa zvimiro zvezvikamu, nekuda kweiyo iri nani yakazara mekiniki zvimiro zvechishandiso mushure me normalizing kana ichienzaniswa neye annealed state, inogona kushandiswa seyekupedzisira kupisa kwekupisa kune mamwe akajairwa maumbirwo akaderera uye kuderera kwekuita zvinodiwa, kuderedza maitiro. , kuchengetedza simba, uye kunatsiridza kugadzirwa kwemaitiro. Uye zvakare, kune mamwe makuru kana akaoma maumbirwo ezvikamu, kana paine njodzi yekutsemuka panguva yekudzima, normalizing inogona kazhinji kutsiva quenching uye tempering kurapwa seyekupedzisira kupisa kupisa.
