He aha nga whakamahinga o nga hiko kauwhata 1. Mo te oumu hiko arc steelmaking Kei te nuinga whakamahia graphite electrode mo te hiko oumu steelmaking. Ka whakamahia e te hanga rino oumu hiko te hiko kauwhata hei arahi i te rere hiko ki roto i te oumu. Ko te naianei kaha ka whakaputa i te rere arc ma te hau i te pito o raro o te hiko, me te whakamahi i te wera i hangaia e te pewa hiko ki te hongi. 2. Mo te oumu arc submerged Ka whakamahia te graphite electrode submerged arc umu ki te whakaputa ferroalloy, silicon parakore, ūkuikui kōwhai, Hāmā me te konupūmā carbide. 3. Mo te oumu parenga Ko te oumu graphitization mo te whakaputa hua graphite, te oumu rewa mo te karaihe whakarewa me te oumu hiko mo te hanga silicon carbide he oumu parenga katoa. Ko nga rauemi mata i roto i te oumu ehara i te mea ko te parenga rino anake, engari ko te whaainga o te whakamahana. 4. Mo te miihini He maha nga graphite electrode burrs e whakamahia ana ki te whakaputa me te tukatuka i nga momo crucibles, graphite poti rīhi, whakarewa mate wera, whakamahana oumu hiko korehau me etahi atu taonga.
