Noocyada iyo Hababka Isticmaalka Qalabka Dib-u-Celinta ee Foornooyinka Dhallaanka Warshadaha

Qalabka kulaylka ugu weyn eefoornada dhalaalka warshadahawaxaa ka mid ah foornada calcination iyo sintering, haanta korantada iyofoornada dhalaalaysa.Dahaarka aagga toogashada ee foornada wareega ayaa guud ahaan lagu dhisay leben aluminium sare leh, leben dhoobo ah ayaa loo isticmaali karaa sida dahaarka qaybaha kale.Lakab ka mid ah fiber-ka-soo-celinta dareenka ayaa la dulsaaraa lakabka kulaylka ee u dhow qolofka foornada, ka dibna lakabka lebennada fudud ama leben fudud ayaa la dhisay.Kabka shubka ah ee tayada leh.

Qolofka unugga electrolytic-ka waxa uu ka samaysan yahay saxan bir ah, waxaana la dhigayaa lakabka looxa dahaarka ah ama fiilada refractory ee gudaha gudaha qolofta, ka dibna leben khafiif ah ayaa la dhisayaa ama la shubay bulukeeti khafiif ah, ka dibna waxaa la dhisay leben dhoobo samee lakab aan shaqaynayn, unugga korantadana wuu shaqeeyaa lakabka waxa kaliya oo laga samayn karaa kaarboon ama silicon carbide maaddooyinka refractory ee leh korantada wanaagsan, si ay iskaga caabiyaan galitaanka aluminium dhalaalaysa iyo nabaadguurka electrolyte fluoride.Waagii hore, lakabka shaqada ee gidaarka unugga ee unugga korantada waxaa guud ahaan lagu dhisay blocks kaarboon.Sanadihii la soo dhaafay, Japan iyo qaar ka mid ah wadamada Galbeedka Yurub waxay isticmaaleen leben silikoon carbide ah oo lagu daray silikoon nitride si loo dhiso, waxayna heleen natiijooyin wanaagsan.

Lakabka shaqada ee hoose ee unugga korantada ayaa guud ahaan ka dhisnaa kaarboon kaarboon oo leh kala-goysyo yaryar oo ay ka buuxaan koollada kaarboon si looga hortago dhexgalka xalalka aluminium iyo kor loogu qaado dhaqdhaqaaqa.

Aluminiumka inta badan la isticmaaloqalabka wax lagu karsadowaa foornada reverberatory.Dahaarka foornada ee xiriirka la leh xalka aluminiumka waxaa guud ahaan lagu dhisay leben aluminium sare leh oo leh A1203 oo ka kooban 80% -85%.Markaad dhalaalayso aluminium bir saafi ah oo nadiif ah, leben badan ama leben corundum waa in la isticmaalaa.Warshadaha qaarkood, leben kaarbide silikoon oo ay weheliso nitride silikoon ayaa loo isticmaalaa dhagaxyada qaybaha u nugul nabaadguurka iyo xidhashada, sida jiirada dabka iyo walxaha aluminiumka qashinka ah.Lebenka carbide ee silikoon isku xidhan ama silikoon nitride ku xidhan ayaa sidoo kale loo isticmaalaa sida dahaarka leh leben zircon.Xiritaanka aluminium ka soo baxa, saamaynta fibre refractory tuurista vacuum ayaa ka fiican.Dahaarka foornada ee aan la xiriirin xalka aluminiumka waxaa guud ahaan lagu dhisay leben dhoobo ah, kabka dhoobada ah ama balaastikada dib u celinta.Si loo dedejiyo xawaaraha dhalaalka oo loo badbaadiyo tamarta, lebennada khafiifka ah, castables refractory ee khafiifka ah iyo alaabooyinka fiber-ka-celinta ayaa guud ahaan loo isticmaalaa lakabyo kulaylka.

Foornada dhalaalaysa ee aluminium dhalada ayaa sidoo kale sida caadiga ah loo isticmaalo qalabka.Dahaarka ayaa guud ahaan ka samaysan alumina-alumina-sare ee kabka la kasban karo ama walxo refractory ah oo leh A1203 ka kooban 70%-80%, iyo shubka refractory corundum ayaa sidoo kale loo isticmaalaa dahaar ahaan.

Aluminiumka dhalaaliyay wuxuu ka soo baxaa aluminiumka foornada iyada oo loo marayo haanta socodka aluminiumka.Dahaarka taangiga guud ahaan waxa uu ka samaysan yahay leben silikoon carbide ah, waxa kale oo jira baloogyo hore loo sii diyaariyay oo ciid silica isku dhafan ah.Haddii baloogga la sii hagaajiyay loo isticmaalo dahaarka taangiga oo kale, dusha sare waa in lagu dahaadhay ciid silica ah oo isku qasan ama Isticmaal sibidhka sare ee alumina ee la isku daray silica ciid refractory castable sida lakab ilaalin ah.
