Annealing inzira yekurapa kupisa kwesimbi isina tsvina yakakandwa mapaipi.Chinangwa chayo ndechekubvisa kusara kunetseka, kudzikamisa zviyero, uye kuderedza maitiro e deformation uye kutsemuka.
Chii chinonzi annealing ye2205 Stainless simbi pombi?
Nepombi inogadzirwa nekushanda kunotonhora, kunaya kwecarbide, kukanganiswa kwelattice, uye kusawirirana kwechimiro uye kuumbwa kuchaita kuti kushora kwesimbi yesimbi kuderera.Panguva ino, annealing kurapwa (kana mhinduro kurapwa) inodiwa.
Nei 2205 pombi yesimbi isina tsvina yakavharwa?
Deredza kuoma kwesimbi uye kuvandudza plastiki kuti iite kucheka uye kutonhora deformation kugadzirisa
Natsa zviyo, homogenize simbi chimiro uye kuumbwa, kunatsiridza zvivakwa zvesimbi kana kugadzirira kunotevera kupisa kurapwa
Bvisa zvakasara mukati kushushikana musimbi kudzivirira deformation uye kuputika.
2205 simbi isina tsvina chubhu annealing maitiro
Mukugadzira, iyo annealing process inoshandiswa zvakanyanya.Zvinoenderana nezvinangwa zvakasiyana-siyana zvekuvharisa zvinodikanwa neiyo workpiece, kune akasiyana annealing maitiro ekutemerwa, anowanzo shandiswa kudzoreredza kushushikana, kupedzisa annealing uye spheroidizing annealing.
Kuderedza kushushikana.Midziyo yakajairika yekudzikisa kushushikana kusungirirwa kwemachubhu esimbi isina simbi inoramba ichipenya inonamira machubhu esimbi isina tsvina, inova muffle rudzi inopenya annealing choto.Iyo inodzivirira gasi sosi inotora choto chekuora ammonia uye ine mudziyo wekuchenesa gasi. Hangao Tech (SEKO Machina) yakaita shanduko yehutofu yevira, kubvisa nzira yekufambisa mesh bhandi uye kuitsiva nekuenderera mberi single-tube roller inoendesa pamutsetse.Midziyo yacho ine hunhu hwehutongi hwepamberi, inoshamisa kuchengetedza simba, kugadzirisa kuri nyore, nezvimwe. Nzvimbo yekudziya yemutsara wese inotora PID otomatiki yakawanda-zone tembiricha yekudzora.Stainless simbi mapaipi kupisa-kurapwa kuburikidza yedu kupisa kwekuchengetedza Stainless simbi pombi inopenya annealing choto kuderedza deformation uye nechokwadi ellipticity yepombi.
Iyo simbi isina tsvina mitsetse yakarongedzerwa zvakaenzana pane yekudyisa rack, inotumirwa kuchoto chinopisa kuburikidza nebhandi rekutakura, inopisa kusvika 1050-1080 ℃ pasi pekuchengetedzwa kwemhepo inodzoreka, uye yozochengetwa kwenguva pfupi, ese macarbides anogona. zvinyungudiswe muvira romoto unopfuta kwazvo.Muchimiro che austenite, uye ndokukurumidza kutonhora kusvika pasi pe350 ° C, mhinduro yakasimba ye supersaturated, kureva, yunifomu unidirectional austenite chimiro, inogona kuwanikwa.
Zvakanyura zvizere.Inoshandiswa kunatsiridza iyo yakaomesesa superheated chimiro neasina kusimba mechanicha zvinhu mushure mekukandira, kuforoma uye welding yepakati uye yakaderera kabhoni simbi.Pisa iyo workpiece kune tembiricha ye 30-50 ° C pamusoro pekupisa uko ferrite yese inoshandura kuita austenite, bata kwenguva yakati, uye wozotonhora zvishoma nezvishoma nechoto.Munguva yekutonhora, iyo austenite inoshandura zvakare, iyo inogona kuita kuti chimiro chesimbi chive chitete..
Spheroidizing Annealing.Inoshandiswa kuderedza kuoma kwepamusoro kwesimbi yemidziyo uye simbi inotakura mushure mekugadzira.Iyo workpiece inopisa kusvika ku20-40 ° C pamusoro pekushisa apo simbi inotanga kuumba austenite, uye inononoka zvishoma nezvishoma mushure mekuchengetedza kupisa.Munguva yekutonhora, iyo lamellar cementite mu pearlite inova spherical, nokudaro kuderedza kuoma.
