Waa maxay nooca foornada soo kicinta ee alaabta ramming ee loo isticmaalo aluminium master alloy?

Isticmaalka alaabada foornada kicinta kicinta ee alwaaxyada sayidyada Dhawaan, soosaarayaal badan oo soo saara foornada foornada wax-soo-saarka ayaa la dhalaaliyay, shuruudaha foornada soo-gelinta alaabada dib-u-celinta waxay noqdeen kuwo sarreeya oo sarreeya. Shuruudaha loogu talagalay impermeability, refractority, caabbinta daxalka, iwm ayaa aad uga sarreeya shuruudihii hore, waxaana sidoo kale rajeyneynaa in kharashka la dhimi karo. Marka loo eego baahida suuqa iyo baahida, warshadda alaabta foornada kuleylkeedu sarreeyo ayaa ka gudubtay sahaminta iyo tijaabinta joogtada ah. Waxa uu si guul leh u horumariyay tiro macaamiisha Alloy-ga ah ee deegaanka, waxaanu kasbaday sumcad wanaagsan iyo ammaanta macaamiisha. Alloys Master-ka ee hadda jira ee suuqa guud ahaan waxay ku saleysan yihiin aluminium aluminium, aluminium copper, aluminium iron, boron titanium aluminium iyo wixii la mid ah. Heerkulka dhalaalinta guud ahaan uma sarreeyo sida tan dhalaalidda birta, laakiin waxa uu ka sarreeyaa heerkulka guud ee aluminiumka.

Sababtoo ah qulqulka xooggan ee aluminium, waa la daadin karaa markaad aragto tolitaanka, iyo dhaqdhaqaaqa aluminiumku waa mid aad u sarreeya, taas oo u nugul falcelinta beddelka. Sidaa darteed, alaabooyin badan oo foornada guud ah laguma soo saari karo dhowr foorno. Sidaa darteed, hadda waa wax caadi ah in la isticmaalo garaafyada garaafyada leh qalabka foornada induction ee ka celinaysa ramming. Si kastaba ha ahaatee, faa’iido darrada walxaha ramming refractory ee foornada induction caadiga ah waa in mar haddii graphite crucible la jabiyo, dahaarka foornada waa in la saaraa, haddii kale foornada waa fududahay in la xidho. Walxahayagii dhawaan la sameeyay ee foornada kicinta ee foornada induction kaliya lama isticmaali karo laakiin sidoo kale waxaa loo isticmaali karaa garaafyada garaafyada. Xaaladda isticmaalka wadajirka ah, xitaa haddii qoloftu ay si lama filaan ah u dillaacdo marka maaddadu ay ka hooseyso maaddada, ma saameyn doonto isticmaalka, weli waa la isticmaali karaa mar kasta, mana jirto baahi loo qabo in laga walwalo xuubka foornada, taas oo aan saameyn ku yeelan doonin shaqada caadiga ah. Kharashyada kale maaha mid sarreeya. Tan iyo markii la aasaasay, waxay si dhakhso ah u heshay tiro badan oo macaamiisha aluminium ah iyada oo loo marayo ammaanta dadweynaha ee macaamiisha.
