Maganin warwarewa, wanda kuma aka sani da maganin maganin, shine tsarin kula da zafi da farko da ake amfani dashi don haɓaka juriya na lalata, kaddarorin injina, da daidaiton tsari na bakin karfe.
Menene annealing?
Annealingwani tsari ne na maganin zafi wanda aka tsara don haɓaka ductility da aiki na kayan aiki ta hanyar rage taurin da kuma kawar da matsalolin ciki. Tsarin ya ƙunshi dumama sarrafawa zuwa takamaiman zafin jiki, riƙe da wannan zafin jiki don ba da damar sauyi tsarin, sannan jinkirin sanyaya-yawanci a cikin tanderu. Annealing inganta microstructure na abu, sa shi mafi uniform da kuma barga. Ana amfani da shi a kan karafa kamar karfe, jan karfe, da tagulla, da kuma kayan kamar gilashi da wasu polymers don haɓaka kayan aikin injiniya da sarrafa su.
Menene Annealed Bakin Karfe?
Bakin karfe da aka rufebakin karfe ne wanda aka yi maganin zafi mai ratsawa don haɓaka halayensa. Wannan tsari ya ƙunshi dumama karfe zuwa yanayin zafi da aka keɓance sannan a sanyaya shi a hankali don rage damuwa na ciki, haɓaka ductility, da sassauta kayan. Saboda haka, bakin karfen da aka rufe yana ba da ingantacciyar injin aiki, ingantaccen tsari, da ingantaccen juriyar lalata idan aka kwatanta da takwaransa da ba a kula da shi ba.
Menene Manufar Bakin Karfe Annealing?
1.Eliminate Intergranular precipitates da kuma mayar da lalata juriya
Ta hanyar narkar da chromium carbides (misali, Cr₃C₂) baya cikin matrix austenitic, maganin maganin yana hana samuwar sassan chromium-depleted, inganta ingantaccen juriya ga lalata intergranular.
2.Cimma Austenitic Microstructure mai kama da juna
Dumama bakin karfe zuwa yanayin zafi mai zafi (yawanci 1050 ° C-1150 ° C) yana biye da sakamakon saurin kashewa a cikin tsari mai daidaituwa da kwanciyar hankali, wanda ke haɓaka aikin kayan gabaɗaya.
3.Inganta Ductility da Tauri
Maganin yana sauƙaƙe damuwa na ciki kuma yana inganta haɓakar hatsi, yana haifar da ingantaccen tsari da juriya mai tasiri.
4.Inganta Machinability
Don bakin karfen da aka yi aikin sanyi, warwarewar bayani yana kawar da tasirin aikin aiki, yana sauƙaƙa sarrafa mashin ɗin da ƙirƙirar aiki na gaba.
5.Shirya Kayan Don ƙarin Jiyya na Zafi
Magani annealing yana ba da ingantaccen tushe microstructural don matakai kamar tsufa ko walda, musamman don hazo-taurare ko duplex bakin karfe.
Misalai na nau'ikan ƙarfe masu dacewa
• Austenitic bakin karfe (kamar 304, 316, 321): Kawar da halayen lalata tsakanin granular
• Hazo hardening bakin karfe (kamar 17-4PH): Maganin maganin da ke biye da tsufa
• Duplex bakin karfe (kamar 2205, 2507): Ana amfani da maganin maganin don samun madaidaicin austenite + ferrite rabo
