Codsiga Birta Kaalshiyamka ee Warshada Samaynta Biraha

Birta kalsiyumku waxay leedahay codsi muhiim ah warshadaha samaynta birta, taas oo hagaajin karta waxqabadka iyo tayada birta.
1. Wakiilka daawaynta kaalshiyamka: kalsiyum macdan ah waxa sida caadiga ah loo isticmaalaa daawaynta kaalshiyamka habka birta samaynta. Marka lagu daro qadar habboon oo kalsiyum ah oo bir ah foornada birta, wasakhowga oksijiinta sida oxides, sulfides iyo nitrides ee birta dhalaalaysa ayaa si wax ku ool ah looga saari karaa, taas oo kor u qaadeysa nadiifnimada birta dhalaalaysa.
2. Deoxidizer: Birta kalsiyum waxa kale oo loo isticmaali karaa deoxidizer ahaan habka birta samaynta. Inta lagu jiro habka dhalaalidda, iyada oo lagu daro calcium macdan ah birta dhalaalaysa, kalsiyumku waxay la falgali kartaa oksijiinta birta dhalaalaysa si ay u soo saarto kalsiyum oxide, oo ay uga falceliso wasakhda ku jirta halabuurka si ay u sameyso oxides, si wax ku ool ah u yareyso nuxurka oksijiinta kala diri iyo hagaajinta saameynta deoxidation ee birta .
3. Beddeeye: Birta kaalshiyamka waxa kale oo loo isticmaali karaa sidii wax ka beddelka si loo hagaajiyo qaab dhismeedka crystal iyo sifooyinka farsamada ee birta. Habka birta samaynta, kalsiyum macdan ah waxa uu kaga falcelin karaa silikoon, aluminium iyo walxo kale oo ku jira birta dhalaalaysa si ay u sameeyaan carbide iyo silicides oo la mid ah kalsiyum oxide, sifee qaybaha, una hagaajiyaan xoogga iyo adkaanta birta.
4. Aloy Additives: Birta kaalshiyamka waxa kale oo loo isticmaali karaa sida wax lagu daro daawaha ee birta si loo hagaajiyo loona hagaajiyo isku dhafka kiimikada iyo sifooyinka birta. Marka loo eego baahiyaha, qadar ku habboon oo kalsiyum ah oo bir ah ayaa lagu dari karaa birta si loo hagaajiyo nuxurka silikoon, beddelo heerkulka martensitic ee birta, oo loo kordhiyo adkaanta.
Birta kalsiyumku waxay door muhiim ah ka ciyaartaa warshadaha samaynta birta, hagaajinta tayada iyo sifooyinka birta. Iyada oo loo marayo codsiga wakiilada daaweynta calcium, deoxidizers, modifiers iyo alloy additives, nadiifinta, saamaynta deoxidation, qaab dhismeedka crystal iyo sifooyinka farsamada ee birta ayaa si wax ku ool ah loo wanaajin karaa si loo daboolo baahiyaha birta ee beeraha codsiyada kala duwan.
