Shin Kunsan Tsarin Narkewar Gwangwani Aluminum?

Gwangwani na aluminum shine abin gani na yau da kullum a cikin rayuwarmu ta yau da kullum, suna aiki a matsayin kwantena don abubuwan sha da sauran kayan masarufi.Wadannan gwangwani an yi su ne daga wani abu mai sauƙi, mai jure lalata, da kuma abin da za a iya sake yin amfani da su - aluminum.Ƙirƙira da sake yin amfani da gwangwani na aluminum sun ƙunshi matakai da yawa, ciki har da narkewar aluminum.A cikin wannan labarin, za mu bincika tsarin narkewa mai ban sha'awa na gwangwani na aluminum, mai da hankali kan mahimman abubuwa kamar wutar lantarki ta narke aluminium, abubuwan cire slag, wakilai masu tacewa, silicon ƙarfe, da matatun yumbun kumfa.

I. Aluminum Narke Furnace
Tsarin narkewar gwangwani na aluminium yana farawa da tanderun narkewar aluminium, wanda ke taka muhimmiyar rawa wajen canza ƙaƙƙarfan aluminum zuwa yanayin narkakkar.Akwai nau'ikan tanderu iri-iri da ake amfani da su a cikin masana'antar, amma waɗanda aka fi sani da su sun haɗa da:
Furnace Reverberatory: An ƙera wannan tander ne da ƙaramin ɗaki mai ɗaki mai ɗaki inda aluminum ke dumama a kaikaice ta hanyar hasken wuta daga rufin da bango.Tanderun na iya kaiwa yanayin zafi har zuwa 1200 ° C, wanda ya fi isa ya narke aluminum.
Crucible Furnace: Wannan nau'in tanderun yana amfani da crucible mai layi don ɗaukar aluminum.Ana ɗora ƙugiyar wuta ta hanyar wutan lantarki ko gas, kuma aluminum yana narkewa a cikinsa.
Induction Furnace: Wannan tanderun yana dogara ne akan shigar da wutar lantarki don samar da zafi a cikin aluminum.Tsarin yana da tsabta kuma yana da ƙarfi, yana sa ya zama sanannen zaɓi don narke aluminum.

II.Wakilan Cire Slag
A lokacin aikin narkewa, ƙazanta a cikin aluminium na iya samar da wani nau'i na slag a saman narkakken ƙarfe.Don tabbatar da ingancin samfurin ƙarshe, yana da mahimmanci don cire slag.Abubuwan cire slag, wanda kuma aka sani da fluxes, sunadarai ne waɗanda ke sauƙaƙe rarrabuwar slag daga narkakken aluminum.Abubuwan cire slag gama gari sun haɗa da masu zuwa:
Sodium Chloride (NaCl): Wannan gishiri yana taimakawa wajen rushe slag, yana sauƙaƙa cirewa.
Potassium Chloride (KCl): Kamar sodium chloride, potassium chloride yana taimakawa wajen tarwatsewar slag, yana haɓaka rabuwa da narkakken aluminum.
Fluxes na tushen Fluoride: Wadannan sauye-sauyen suna taimakawa wajen kawar da ƙazanta na oxide da kuma rage wurin narkewa na slag, yana sauƙaƙa cirewa.

III.Wakilan Masu Tacewa

Ana amfani da abubuwan tacewa don haɓaka ingancin narkakkar aluminum ta hanyar cire ƙazanta irin su hydrogen gas da haɗawa.Wasu wakilai na yau da kullun na tacewa sun haɗa da:

Hexachloroethane (C2Cl6): Wannan fili yana bazuwa a cikin narkakkar aluminum, yana fitar da iskar chlorine wanda ke amsawa da ƙazanta, yana sauƙaƙa cire su.
Nitrogen Gas (N2): Lokacin da iskar nitrogen ke kumfa ta cikin narkakkar aluminum, yana taimakawa wajen cire iskar hydrogen da abubuwan da aka haɗa.
Argon Gas (Ar): Kamar nitrogen, ana iya amfani da iskar argon don cire iskar hydrogen da haɗawa daga narkakken aluminum.

IV.Karfe Silicon

Ana ƙara siliki na ƙarfe zuwa narkakken aluminum a matsayin sinadari mai haɗawa.Ƙarin siliki na ƙarfe yana inganta kayan aikin injiniya na samfurin ƙarshe, kamar ƙarfinsa da taurinsa.Bugu da ƙari, silicon kuma yana taimakawa wajen tace narkakkar aluminum ta hanyar mayar da martani tare da ƙazanta da inganta cire su.

A ƙarshe, tsarin narkewar gwangwani na aluminum hanya ce mai rikitarwa amma mai ban sha'awa wacce ta ƙunshi abubuwa da matakai masu mahimmanci da yawa.Tanderun narkewar aluminium, ko ya zama mai reverberatory, crucible, ko induction tander, yana aiki a matsayin kashin baya na tsari, yana ba da damar sauya ingantaccen aluminum zuwa yanayin narkakkar.Abubuwan kawar da Slag, irin su sodium chloride da potassium chloride, suna taka muhimmiyar rawa wajen kawar da ƙazanta da tabbatar da ingancin narkakkar aluminum.Abubuwan da ake tacewa, kamar hexachloroethane da iskar nitrogen, suna ƙara haɓaka inganci ta hanyar cire iskar hydrogen da haɗaɗɗun.Bugu da kari na karfe silicon a matsayin alloying kashi ba kawai inganta inji kaddarorin na karshe samfurin amma kuma taimaka wajen tacewa tsari.A ƙarshe, matatun yumbura kumfa suna taimakawa a cikin tsaftar ƙarshe na narkakkar aluminum, yana haifar da mafi tsabta da ingantaccen samfurin ƙarshe.Fahimtar waɗannan abubuwa masu mahimmanci da matakai suna ba da haske mai mahimmanci game da gagarumin tsari bayan samarwa da sake yin amfani da gwangwani na aluminum.
