Warshadaha samaynta birta, birta birta ahi waa weel muhiim ah oo qaada, xajiya, oo daaweeya birta dhalaalaysa inta u dhaxaysa hababka wax soo saarka ee kala duwan. Waxqabadkeedu wuxuu si toos ah u saameeyaa tayada birta, hufnaanta wax soo saarka, iyo kharashyada hawlgalka. Si kastaba ha noqotee, birta dhalaalaysa waxay gaartaa heerkul aad u sarreeya 1,600 ° C ama ka badan, waxayna sidoo kale la falgashaa qulqulka gardarrada, nabaad guurka farsamada, iyo shoogga kulaylka - taasoo caqabado ba'an ku ah walxaha dib-u-celinta ee dahaarka birta. Tani waa meeshaleben kaarboon magnesium(MgO-C leben) waxay u taagan yihiin xalka kama dambaysta ah, iyagoo keenaya adkeysiga aan la isku halayn karin iyo isku halaynta hawlaha birta.
Waa maxay sababta bulukeetiyada Kaarboonka ee Magnesium ay lagama maarmaanka u yihiin birta
Saqafka birta ahi waxay u baahan yihiin agab dib-u-celin ah oo u adkeysan kara xaaladaha ba'an iyada oo aan waxyeello loo geysan waxqabadka. Leben-dhaqameedka caaddigga ah ayaa inta badan ku guul-darraysta inay buuxiyaan shuruudahan, taasoo keenta beddelaad joogto ah, waqti-soo-saarka, iyo korodhka kharashyada. Lebenka kaarboonka ee Magnesium, si kastaba ha ahaatee, waxay isku daraan xoogga magnesia-nadiifinta sare (MgO) iyo graphite si ay wax uga qabtaan caqabad kasta oo muhiim ah ee dahaarka birta:
1. Caabbinta Heerkulka Sare ee Gaarka ah
Magnesia, oo ah qaybta xudunta u ah lebenka MgO-C, waxay leedahay meel dhalaalaysa oo aad u saraysa oo ku dhow 2,800°C—oo aad uga badan heerkulka ugu badan ee birta dhalaalaysa. Marka lagu daro garaafka (walax leh xasilooni kulayl aad u fiican), lebenka kaarboon ee magnesium waxay ilaalinayaan sharaftooda qaab dhismeedka xitaa hoos u dhigista dheer ee birta dhalaalaysa ee 1,600+°C. Iska caabbintani waxay ka hortagtaa jilicsanaanta lebenka, qallafsanaanta, ama dhalaalka, hubinta in birta birta ahi ay badbaado tahay oo shaqaynayso muddo dheer.
2. Iska caabinta Daxalka Slag Sare
Birta dhalaalaysa waxa weheliya slags—products-ka hodanka ku ah oksaydhisku (sida SiO₂, Al₂O₃, iyo FeO) kuwaas oo aad u daxal-maray dib-u-celinta. Magnesia ee lebenka MgO-C waxay si yar uga falcelisaa xargahaan, iyaga oo ka samaysanaya lakab cufan oo aan la nadiifin karin oo ku yaal dusha lebenka kaas oo xannibaya soo gelista dharbaaxada. Si ka duwan lebenka alumina-silica, kuwaas oo si fudud u baabi'in kara aashitada ama lakabyada aasaasiga ah, lebenka kaarboon ee magnesium waxay ilaalinayaan dhumucdooda, yaraynta khatarta dheecaanka leaks.
3. Iska caabinta shoogga kulaylka heer sare ah?
Saqadaha birta ah waxay maraan kuleyl soo noqnoqda (si ay u qabtaan birta dhalaalaysa) iyo qaboojinta (inta lagu jiro dayactirka ama xilliyada shaqo la'aanta) - habka keena shoogga kulaylka. Haddii alaabta dib-u-celinta aysan u adkeysan karin isbeddelada heerkulka degdega ah, way dillaaci doonaan, taasoo keenta guuldarro degdeg ah. Garaafka ku jira lebenka kaarboonka ee magnesium waxa uu u shaqeeyaa sidii “buffer,” nuugaysa diiqada kulaylka iyo ka hortagga samaynta dildilaaca. Tani waxay ka dhigan tahay lebenka MgO-C waxay u adkeysan karaan boqolaal wareegyada qaboojinta kuleylka iyada oo aan la lumin waxqabadka, kordhinta nolosha adeegga dahaarka birta.
4. Kharashyada xidhashada iyo dayactirka oo la dhimay
Xirashada makaanikada ee ka dhalata birta dhalaalaysa, dhaq-dhaqaaqa ladle, iyo xoqidda dharbaaxada ayaa ah arrin kale oo weyn oo loogu talagalay dib-u-celinta birta. Lebenka kaarboon ee Magnesium waxay leeyihiin awood farsamo oo sarreeya iyo adkaantooda, taas oo ay ugu wacan tahay isku xidhka u dhexeeya miraha magnesia iyo garaafka. Waartani waxa ay yaraynaysaa xidhashada lebenka, taas oo u ogolaanaysa in xadhigu ku shaqeeyo wakhti dheer inta u dhaxaysa relins. Dhirta birta ah, tani waxay u tarjumeysaa wakhtiga dhimista, hoos u dhaca kharashka shaqada ee beddelka diidmada, iyo jadwal wax soo saar oo joogto ah.
Codsiyada Muhiimka ah ee Biraha Kaarboon ee Magnesium ee ku jira Laadyada Birta
Lebenka kaarboon ee Magnesium ma aha hal-cabbir-ku-habboon-dhammaan-xalka-waxay ku habboon yihiin qaybo kala duwan oo ka mid ah birta birta ah oo ku salaysan heerarka walaaca gaarka ah:
Gunta iyo gidaarada:Darbiyada hoose iyo kuwa hoose ee gogosha ayaa si toos ah, xidhiidh wakhti dheer u leh birta dhalaalaysa iyo dhogorta. Halkan, lebenka kaarboonka ee magnesium cufan (oo leh 10-20% graphite content) ayaa loo isticmaalaa si looga hortago daxalka iyo xirashada.
Ladle Slag Line:Xariiqda xargaha ayaa ah meesha ugu nugul, maadaama ay wajaheyso soo-gaadhis joogto ah oo ku saabsan dharbaaxada daxalka ah iyo shoogga kulaylka. Lebenka kaarboonka ee magnesium-ka ah (oo leh graphite-ka sare iyo antioxidants lagu daray sida Al ama Si) ayaa halkan la geeyay si loo kordhiyo nolosha adeegga.
Duubka Ladle iyo Daloolka Taabo:Meelahani waxay u baahan yihiin leben leh koror kuleyl sare leh iyo caabbinta nabaad guurka si loo hubiyo socodka birta dhalaalaysa ee siman. Leben khaas ah oo MgO-C ah oo leh magnesia miro-dhuuban ayaa loo isticmaalaa si looga hortago xidhidhsiga iyo kordhinta nolosha sanka.
Faa'iidooyinka dhirta birta ah: Ka baxsan cimriga
Doorashada leben magnesium ee kaarboonka ee loogu talagalay dahaarka birta ee birta waxay soo saartaa faa'iidooyin ganacsi oo la taaban karo oo loogu talagalay soosaarayaasha birta:
Tayada birta oo la hagaajiyay:Iyada oo laga hortagayo nabaad guurka refractory, lebenka MgO-C waxa ay yareeyaan halista walxaha refractory ee wasakhaysan birta dhalaalaysa—iyaga oo hubinaya isku dhafka kiimikaad ee joogtada ah iyo cilladaha yar ee alaabada birta dhammaatay.
Keydka Tamarta:Heerarka kulaylka sare ee garaafka ee lebenka MgO-C waxay gacan ka geysataa in kulaylka lagu hayo saqafka, yaraynta baahida dib u kululaynta birta dhalaalaysa. Tani waxay hoos u dhigtaa isticmaalka shidaalka iyo qiiqa kaarboonka
Nolosha Adeegga Ladle ee Dheeraadka ah: Celcelis ahaan, dahaarka leben kaarboon ee magnesium waxa uu socdaa 2-3 jeer in ka badan dahaarka caaqilka ah. Qalabka birta ah ee caadiga ah, tani waxay ka dhigan tahay hal mar oo keliya 6-12 bilood, marka la barbardhigo 2-3 jeer sannadkii oo leh qalab kale.
