Tallaabooyinka Habaynta:
Xoq → Dooro& Goyn → Dhalashi → Sifeyn (decarbonize) → Atomizing → Qallajin → Baadhitaanka Scalper → Daboolista&Afuufid si meesha looga saaro daloolka hawada
QIIMAHA FAA'IIDADA BADAN EE KAAROON HOOS YAHAY
• Waxqabadka in ka badan 20% ka dhanka ah tallaalada kaarboonka sare
• Xirashada mashiinada iyo qalabka oo yaraada taasoo ay ugu wacan tahay nuugista tamarta badan ee saamaynta qaybaha
• Qaybaha ka nadiifsan cilladaha ka dhasha daaweynta kulaylka, jabka ama dildilaaca yaryar
HORMARINTA DEEGAANKA
• Yaraynta budada
• Qaab-dhismeedka yaryar ee Bainitic waxa uu dammaanad qaadayaa in aanay jebin doonin inta lagu jiro nolosheeda waxtarka leh
MUUQAALKA GUUD
Qaabka toogashada birta kaarboon ee hooseeya waxay la mid tahay wareega.Joogitaanka ugu yar ee qaybo dhaadheer, qaybo qallafsan oo leh dalool, dharbaaxo ama wasakh ayaa suurtagal ah.
Tani ma saameynayso waxqabadka tallaalka, waxaa lagu xaqiijin karaa iyada oo la cabbirayo waxqabadkeeda mashiinka.
Adag
Qaab-dhismeedka yar yar ee bainitic wuxuu dammaanad qaadayaa heerar adag oo adag.90% qaybuhu waxay u dhexeeyaan 40 - 50 Rockwell C.
Kaarboonka hooseeya ee dheellitirka manganese wuxuu dammaanad qaadayaa nolol dheer oo faa'iido leh oo ka mid ah qaybaha, sidaas darteed hagaajinta nadaafadda qaybaha, maaddaama shaqada farsamada ay kordhiyaan adkaantooda.
Tamarta qarxinta rasaasta waxaa inta badan nuuga qaybaha, sidaas darteed hoos u dhigista daminta mishiinka.
GRANULATION KAARBON, WAXQABAD SARE
Isticmaalka tallaalka birta kaarboon ee hooseeya wuxuu leeyahay baaxadda mashiinnada leh marawaxadaha 2500 ilaa 3000 RPM iyo xawaarahooda 80 M / S.
Qalabka cusub ee isticmaala 3600 RPM marawaxadaha iyo xawaarahooda 110 M/S, kuwani waa shuruudo lagu kordhinayo wax soo saarka.
