Umphakamisi wekhabhoni yinto yekhabhoni, eveliswa kubushushu obuphezulu kwaye isetyenziselwa i-carburization yentsimbi kunye nentsimbi.
Isetyenziswe ngexesha le-steelmaking kunye nomxholo wentsimbi ephantsi (ukuvumela insimbi kunye nekhabhoni) ekuhlawuleni kwi-oxygen converter kunye neenkqubo ze-electrosmelting.Kwi-metallurgy carbon raiser (i-graphite egayiweyo) isetyenziswa ngokubanzi kwi-slag foaming, ngexesha lokuvelisa i-graphite yamalahle, njengesizaliso seplastiki eqiniswe ngegraphite.
