Lapho ukuthetheliswa kufudumala, isikhathi sokuhlala isikhathi side kakhulu ekushiseni okuphezulu, umoya-mpilo esithandweni somlilo kanye nomoya-mpilo omoyeni wamanzi uhlangana nama-athomu we-iron of the oxidation abizwa ngokuthi yi-oxidation. I-Fusible eyakhiwe ngokunamathela kwe-iron oxide ebusweni besikhumba sensimbi solide oxide oxide, njengokusiza ngaphambi kokususa ukungcola, kuzocindezelwa ebusweni bokuthi, kuhlanze noma ngemuva kokukhamba, kwakhiwa i-sag ye-sagukwakha ingaphezulupitting, stican uma ubizela usayizi we-geometry, isibonelelo semishini, noma umphumela onganele futhi wenze izingxenye ngobuso obumnyama ku-scrap, kuzoba nomphumela ekuqondeni kwe-Ukufa Kuza Kwecala.

Izindlela zokuvimbela i-oxidation yile:
.
.
(3) Gcina ingcindezi encane enhle esithandweni sokuvimba umoya obandayo usuka ekuthini ungene esithandweni somlilo.
. i-oxide scale.
