Dulmar guud oo ku saabsan Birta Tareenka
Biraha tareenadu waa qaybaha ugu muhiimsan ee tareenada tareenka. Shaqadoodu waa inay hagto giraangiraha shayga rogroga si ay hore ugu socdaan, u qaadaan cadaadiska weyn ee giraangiraha, una gudbiyaan kuwa seexda. Biraha tareenadu waa inay bixiyaan dusha sare ee rogroga oo joogto ah, siman oo aan jiid lahayn oo loogu talagalay giraangiraha. Tareenada korontada ku shaqeeya ama qaybaha xannibaadda otomaatiga ah, biruhu sidoo kale waxaa loo isticmaali karaa wareegyo tareen.
Waxyaabaha Caadiga ah ee Birta Raad-raaca
Sida ku xusan nooca birta, tareenka waxaa loo qaybin karaa saddex nooc:
Birta kaarboonka ah
Birta kaarboonku waa bir bir ah oo lagu dhalaaliyo laguna duubo macdanta birta ceeriin ee dabiiciga ah. Waxay inta badan isticmaashaa curiyayaasha kaarboonka iyo manganese ee ku jira macdanta si loo kordhiyo xoogga tareenka. Birta tareenka ee caadiga ah ee kaarboonku waxay ka kooban tahay 0.40%-0.80% kaarboon iyo manganese oo ka yar 1.30%-1.4%.
l Birta Daawaha
Birta daawadu waa bir bir ah oo la dhalaaliyo oo la duubo ka dib marka lagu daro xaddi ku habboon oo walxo daawadu ka samaysan yihiin sida vanadium, titanium, chromium, iyo tin ah macdanta birta asalka ah. Xoogga iyo adkaanta noocan ah ee birta ayaa ka sarreeya kan birta kaarboonka.
l Birta kulaylka lagu daweeyay
Birta kulaylka lagu daweeyay waa bir bir ah oo lagu sameeyo kuleylinta iyo xakamaynta qaboojinta birta kaarboonka kulul ama birta dahaarka leh. Qaab-dhismeedka luulka ee birta kulaylka lagu daweeyay ayaa ka sii fiican kan birta kulul lagu daweeyay, taasoo keenta xoog iyo adkaysi sare. Birta adag ka dib daaweynta kulaylka waxay leedahay lakab hagaajin adag oo ku yaal madaxa tareenka, taas oo si weyn u wanaajisa sifooyinkeeda farsamada si cimriga adeegga tareenka loo dheereeyo.
