Ko bakin karfe bututu zai zama mai haske bayan annealing yafi dogara da wadannan tasiri da dalilai:
1. Ko zafin zafi na annealing ya kai ƙayyadadden zafin jiki. Maganin zafi na bututun bakin karfe gabaɗaya yana ɗaukar maganin zafi mai zafi, wanda shine abin da mutane sukan kira "annealing". Yanayin zafin jiki shine 1040 ~ 1120 ℃ (Japan misali). Hakanan zaka iya lura ta hanyar ramin kallo na murhun wuta. Bututun bakin karfe a wurin da ake cirewa ya kamata ya kasance a cikin yanayi mara kyau, amma bai kamata a yi laushi da sagging ba.
2. yanayi mai ban tsoro. Gabaɗaya, ana amfani da tsantsar hydrogen a matsayin yanayi mai banƙyama. Tsaftar yanayi ya fi dacewa sama da 99.99%. Idan dayan bangaren iskar iskar iskar gas ce, tsaftar na iya zama kasa, amma dole ne bai kunshi iskar oxygen ko tururin ruwa da yawa ba.
3. Rushewar jiki ta wuta. Ya kamata a rufe murhun wuta mai haske kuma a ware daga iska ta waje; idan an yi amfani da hydrogen a matsayin iskar kariya, tashar shaye-shaye ɗaya kawai ya kamata a buɗe (amfani da ita don kunna hydrogen ɗin da aka fitar). Hanyar dubawa na iya zama a shafa ruwan sabulu a kan mahaɗin tanderun da ke ɗaurewa don ganin ko akwai zubar iska; Wuraren da ya fi dacewa don zubar da iska su ne wuraren da bututun ke shiga da fita daga tanderun da ke rufewa. Zoben rufewa a wannan wuri suna da sauƙin sawa musamman. Duba kuma canza akai-akai.
4. Matsi mai kariya. Don hana ƙwayar ƙwayar cuta, iskar gas mai kariya a cikin tanderun ya kamata ya kula da wani matsi mai kyau. Idan iskar gas ce mai kariyar hydrogen, gabaɗaya yana buƙatar fiye da 20kBar.
5. Turin ruwa a cikin tanderun. Na farko shine a bincika gabaɗaya ko kayan jikin tanderun ya bushe. Lokacin shigar da wutar lantarki a karon farko, dole ne a bushe kayan jikin tanderun; na biyu shine duba ko akwai tabo da yawa akan bututun bakin karfe dake shiga cikin tanderun. Musamman idan akwai ramuka a cikin bututu, kar a zubar da ruwa a ciki, in ba haka ba zai lalata yanayin wutar lantarki. Abin da kuke buƙatar kulawa shine waɗannan. A yadda aka saba, bututun bakin karfe da ya kamata a ja da baya game da mita 20 bayan bude tanderun zai fara haskakawa, mai haske da haske. An ƙera shi don ƙaƙƙarfan haske na kan layi na masana'antun bututu na bakin karfe kuma ya dogara ne akan tsarin buƙatun buƙatun-gefen buƙatun. Dangane da buƙatun, ya ƙunshi cikakken saitin kayan aiki wanda ya ƙunshi jerin IWH duk-ƙarfin-jihar IGBT ultra-audio induction dumama wutar lantarki, na'urar kariya ta gas, na'urar ma'aunin zafin infrared, na'urar bazuwar ammonia, tsarin sanyaya ruwa, na'urar tsaftacewa, tsarin kula da lantarki da na'urar kwantar da wutar lantarki. Yin amfani da inert yanayi azaman yanayin kariya, aikin aikin yana mai zafi kuma yana sanyaya a yanayin zafi mai zafi ba tare da iskar oxygen ba don cimma tasirin jiyya mai haske. Kayan aiki yana ɗaukar tsarin dumama mai ci gaba da rukuni. A lokacin dumama, ana ƙara iskar gas a cikin bututun tanderun don ragewa da kare wayar ƙarfe, yana sa samansa yayi haske sosai. (Matte matte) yana rage yawan iskar shaka na saman karfe, yana kara samun kaddarorin anti-tsatsa.
