Kookaha batroolka ee sawiran ee loo isticmaalo warshadaha shubka birta ee ductile
Sharaxaad Gaaban:
Kookaha batroolka ee graphitized-ka ah ee saafiga ah waxaa laga sameeyaa kookaha batroolka ee tayada sare leh heerkulkiisuna yahay 2,500-3,500℃. Maadaama uu yahay walax kaarboon saafi ah, wuxuu leeyahay astaamo kaarboon go'an oo sarreeya, baaruud hooseeya, dambas hooseeya, dalool hoose iwm. Waxaa loo isticmaali karaa sidii kor u qaadis kaarboon (Recarburizer) si loo soo saaro bir tayo sare leh, bir la shubay iyo daawaha. Waxa kale oo loo isticmaali karaa balaastig iyo caag ahaan wax lagu daro.
