A fannoni kamar gina bangon labule, gidajen kayan aiki, da kuma maƙallan ɗaukar hoto, na'urorin ƙarfe na galvalume suna maye gurbin na'urorin ƙarfe na galvalume na gargajiya a hankali a matsayin babban zaɓi saboda fa'idodi biyu na juriya ga tsatsa da kuma ingancin farashi. Ko dai farashin na'urorin ƙarfe na Galvalume ne, muhimmin abin la'akari a fannin siyan injiniya, ko kumaASTM A792 GalvalumeDangane da ƙayyadaddun bayanai da aka bayyana a sarari a cikin ƙa'idodin samarwa, bambance-bambancen aikin asali ya samo asali ne daga daidaitaccen sarrafa abun da ke ciki. A yau, za mu fara da nazarin abun da ke ciki don warware sirrin aikin na'urorin ƙarfe na galvalume (gami da Galvalume Roll, Steel Coil Galvalume, da sauransu).
I. Binciken Tsarin Tsarin Nauyin Galvalume Karfe
Ana ƙayyade aikin na'urorin ƙarfe na galvalume ta hanyar "kayan tushe" da kuma "rufi." Girman sassa daban-daban kai tsaye yana shafar yanayin da ya dace na samfurin ƙarshe. Misali, ƙirar kayan aikin Galvalume Steel Coil Az150, wanda ke buƙatar juriya mai ƙarfi ga tsatsa, ya bambanta sosai da na Galvalume Coil na yau da kullun.
1. Tsarin Rufi: "Rabon Zinare" na Aluminum, Zinc, da Silicon

Rufin aluminum da zinc ba ƙarfe ɗaya ba ne, amma tsarin ƙarfe ne na aluminum (55%), zinc (43.5%), da silicon (1.5%). Wannan rabo shine mafita mafi kyau da aka tabbatar ta hanyar aiki na dogon lokaci:
* Aluminum (Al): "Cibiyar da ke jure wa tsatsa" ta shafi murfin. Aluminum yana samar da wani fim mai kauri na Al₂O₃ oxide a saman murfin karfe, wanda zai iya jure wa tsatsa daga yanayi mai tsauri kamar ruwan sama mai guba da feshin gishiri. Wannan shine babban dalilin da yasa murfin karfe mai rufi da aluminum-zinc yana da juriyar tsatsa sau 3-5 fiye da na'urorin karfe na galvanized na yau da kullun;
* Zinc (Zn): Yana taka rawar "kariyar hadaya ta anode." Idan aka goge murfin, zinc zai fi dacewa ya yi aiki da iskar oxygen don hana ƙarfen tushe yin tsatsa. A lokaci guda, kasancewar zinc kuma zai iya inganta lanƙwasa murfin, wanda hakan zai sauƙaƙa wa Galvalume Roll lanƙwasa da tambari;
* Silicon (Si): Yana magance matsalar "mannewa na rufi". Silicon na iya hana amsawar da ke tsakanin aluminum da ƙarfe don samar da mahaɗan Fe-Al masu ƙarfi da ƙarfi, wanda ke rage haɗarin barewar rufi. Tasirin daidaita silicon yana da mahimmanci musamman ga Galvalume Steel Coil Az150 mai kauri (AZ150 yana wakiltar 150g na nauyin rufi a kowace murabba'in mita).
2. Tsarin Substrate: "Garantin Asali" na Ƙaramin Carbon

Substrate nana'urorin ƙarfe na galvalumegalibi ƙarfe ne mai ƙarancin carbon (ƙarfin carbon ≤0.12%), wanda aka ƙara masa ƙaramin manganese (0.3-0.6%) da phosphorus (≤0.045%): Carbon (C): Yawan sinadarin carbon zai sa substrate ya yi tauri sosai, wanda hakan zai sa ya yi saurin fashewa yayin sarrafawa; ƙarancin abun ciki zai rage ƙarfin na'urar ƙarfe. Saboda haka, dole ne a sarrafa yawan sinadarin carbon na ƙarfe mai ƙarancin carbon sosai a cikin "ƙarfi da daidaiton sarrafawa"; Manganese (Mn): Ƙaramin adadin manganese zai iya inganta ƙarfin yawan amfanin ƙasa ba tare da yin tasiri sosai ga danshi ba, wanda hakan ya sa ya dace da aikace-aikacen ɗaukar kaya (kamar galvalume na ƙarfe don maƙallan photovoltaic); Phosphorus (P): Phosphorus yana ƙara karyewar ƙarfe, don haka dole ne a iyakance yawan sinadarin phosphorus a cikin substrate sosai, wanda kuma yana ɗaya daga cikin alamun da aka ƙayyade a cikin ma'aunin ASTM A792 Galvalume.
II. Alaƙar da ke Tsakanin Haɗaɗɗen Siffofi da Muhimman Halayen Aiki Fahimtar yadda aka tsara abun da ke ciki yana ba mu damar fahimtar dalilin da yasa wasu ke yin hakan.Galvalume Coilssun dace da gini a waje yayin da wasu kuma sun dace da layukan kayan aiki—mahimmin abu shine bambance-bambancen aiki da suka samo asali daga gyare-gyaren kayan aiki.

1. Juriyar Tsatsa: Abubuwan Aluminum Suna Ƙayyade "Matsayin Kariya" Juriyar Tsatsa shine babban gasa namirgina na galvalume, kuma alaƙar da ke tsakaninsa da abun da ke ciki kai tsaye ce: Lokacin da sinadarin aluminum na murfin ya ƙaru daga kashi 50% zuwa kashi 55%, yawan fim ɗin oxide na Al₂O₃ ya inganta sosai. A cikin yanayin feshin gishiri a bakin teku, lokacin tsatsa na na'urar ƙarfe na iya ƙaruwa daga shekaru 10 zuwa sama da shekaru 20. Idan sinadarin silicon ya ƙasa da kashi 1%, zai haifar da raguwar mannewa tsakanin murfin da substrate, wanda hakan ke sa murfin ya yi kama da ƙura a gwaje-gwajen feshin gishiri; idan ya wuce kashi 2%, zai ƙara karyewar murfin, don haka rage juriyar tsatsa. Wannan kuma shine dalilin da ya sa Galvalume Steel Coil AZ150 yana da ƙarfin juriyar tsatsa fiye da AZ100 (rufin 100g a kowace murabba'in mita) - ba wai kawai murfin ya fi kauri ba, har ma da rabon aluminum-zinc-silicon ya fi dacewa da buƙatun kariya mai girma.
2. Halayen Inji: Tsarin Substrate Ya Mamaye "Ƙarfi da Ikon Sarrafawa"
Ƙarfi: Ga kowace ƙaruwar 0.1% a cikin sinadarin manganese na substrate, ƙarfin yawan amfanin na'urar ƙarfe na iya ƙaruwa da 5-8 MPa. Saboda haka, ga na'urar Galvalume Steel Coil da ake amfani da ita wajen amfani da kayan ɗaukar kaya, ana sarrafa yawan manganese a 0.5-0.6%.
Tsarin sarrafawa: Don aikace-aikacen da ke buƙatar tambari mai rikitarwa, kamar su akwatunan kayan aiki, ana zaɓar substrates tare da abun ciki na carbon ≤0.1%, yayin da ake rage abun ciki na silicon na murfin zuwa kusan 1.5% don hana fashewa na shafi yayin tambari. 3. Juriyar Zazzabi Mai Girma: Fa'idar Aluminum na "Tsawon Zazzabi Mai Girma"
Wurin narkewar aluminum (660℃) ya fi na zinc (419℃) girma sosai, saboda haka, juriyar zafin jiki na na'urorin ƙarfe na zinc da aka yi da aluminum ya fi na na'urorin ƙarfe na galvanized kyau:
A cikin yanayin zafi ƙasa da 200℃ (kamar rufin tanda), aikin rufin yana da karko;
Ko da a ƙarƙashin yanayin zafi na ɗan gajeren lokaci na 300℃, fim ɗin Al₂O₃ zai iya hana iskar shaka a cikin rufi, wanda shine babban dalilin da yasa Galvalume Roll ya dace da bututun hayaki da rufin bututu mai zafi.

III. Alaƙar da ke Tsakanin Haɗawa, Aiki, da Farashin Na'urar Karfe ta Galvalume

Mutane da yawa suna mamaki yayin sayayya: Me yasa bambancin farashi na Galvalume Coil na irin wannan ƙayyadaddun bayanai zai iya kaiwa RMB 100-200/ton? A taƙaice, bambancin farashi yana nuna farashin abubuwan da aka haɗa: Kudin shafa: Farashin kasuwa na aluminum ya ninka na zinc sau 2-3. Saboda haka, mafi girman abun ciki na aluminum a cikin shafa (misali, AZ150 idan aka kwatanta da AZ90), mafi girman farashi, kuma mafi girman Farashin Galvalume Steel Coil. Farashin kayan tushe: Mafi girman abun ciki na manganese da ƙarancin abun ciki na phosphorus a cikin ƙarfe mai ƙarancin carbon, mafi girman farashin narkewa, kuma mafi girman farashin Galvalume Steel Coil da ya dace. Matsakaicin farashi: Kayayyakin da suka dace da ma'aunin ASTM A792 Galvalume suna da ƙaƙƙarfan ikon sarrafa jurewar sassan (misali, karkacewar abun ciki na aluminum ≤ ±1%), mafi girman ƙimar shara yayin samarwa, da farashi 5-8% sama da samfuran da ba na yau da kullun ba. IV. Yanayin Amfani Mai Amfani: Muhimmancin Zaɓin Abun Ciki

Wani aikin gina bakin teku ya kwatanta nau'ikan na'urorin ƙarfe na galvalume guda biyu: Na'urar Galvalume ta Ordinary (50% aluminum, 1% silicon): Tsatsa ta bayyana bayan shekaru 3 na amfani; Na'urar Galvalume Steel Coil Az150 (55% aluminum, 1.5% silicon), wanda ya dace da ASTM A792: Babu wani tsatsa mai mahimmanci bayan shekaru 5 na amfani, kuma babu wani nakasa a lokacin tasirin guguwa (ƙananan halayen injiniya). A ƙarshe aikin ya zaɓi na ƙarshe. Duk da cewa farashin farko na Na'urar Galvalume Steel Coil ya fi 150 RMB/ton girma, an tsawaita tsawon rayuwar sabis da fiye da shekaru 10, wanda ya haifar da ƙarancin farashi na dogon lokaci.

Kammalawa: Tsarin haɗakar na'urorin ƙarfe na galvalume tsari ne na "buƙatu masu dacewa daidai": An zaɓi AZ150 (babban aluminum, babban silicon) don juriyar tsatsa mai yawa; an zaɓi ƙananan silicon, ƙananan carbon substrates don sarrafawa mai rikitarwa; kuma an zaɓi samfuran ASTM A792 na yau da kullun don ayyukan fitarwa. Tare da ci gaban masana'antar samar da wutar lantarki da sabbin makamashi a nan gaba, inganta tsarin (kamar ƙara adadin abubuwan ƙasa masu wuya don inganta juriyar tsatsa) zai zama muhimmin alkiblar ci gaba ga na'urorin ƙarfe na zinc da aka yi da aluminum, yana ƙara faɗaɗa iyakokin aikace-aikacen su.
