Chinyorwa: Fe2O3 + 2 Al → 2 Fe + Al2O3Zvimwewo, pig iron inogona kugadzirwa kuita simbi (ine 2% kabhoni) kana simbi yakaumbwa (simbi yakachena kutengeserana). Maitiro akasiyana-siyana akashandiswa kune izvi, kusanganisira finery forges, puddling furnaces, Bessemer converters, open hearth furnaces, basic oxygen furnaces, uye magetsi arc furnaces. Muzviitiko zvose, chinangwa ndechekuisa mamwe kana kuti carbon yose, pamwe chete nezvimwe zvisiri izvo. Kune rumwe rutivi, dzimwe simbi dzinogona kuwedzerwa kuti dziite alloy steels. Mubvunzo: Chii chinonzi oxidation chiri kuedza kubvisa?
