Iindlela zokuvelisa i-carbon ferrochrome ephezulu ziquka indlela yesithando sombane, i-shaft furnace (i-blast furnace) indlela, indlela yeplasma kunye nendlela yokunciphisa inyibilika. Indlela yesithando somlilo ngoku ivelisa kuphela i-chromium alloy ephantsi (Cr <30%), umxholo ophezulu we-chromium (njenge-Cr> 60%) yenkqubo yokuvelisa isithando somlilo kusekho kwinqanaba lophando; iindlela ezimbini zokugqibela ziyaphononongwa kwinkqubo esakhulayo; ngoko ke, uninzi lwezorhwebo lwe-ferrochrome ephezulu yekhabhoni kunye ne-ferrochrome eyenziwe ngokutsha isetyenziselwa ukuveliswa kweziko lombane (i-mineral furnace) indlela.
(1) Iziko lombane lisebenzisa umbane, owona mthombo wamandla ucocekileyo. Eminye imithombo yamandla efana namalahle, icoke, ioyile ekrwada, igesi yendalo, njl. Kuphela iziko zombane ezinokuthi zivelise i-alloys ecocekileyo.
(2) Umbane kuphela komthombo wamandla onokufumana iimeko zobushushu obuphezulu ngaphandle kwesizathu.
(3) Isithando somlilo sombane sinokuqonda ngokulula iimeko ze-thermodynamic ezifana noxinzelelo lwe-oxygen inxalenye kunye noxinzelelo lwe-nitrogen inxalenye efunwa yi-metallurgical reactions ezifana nokunciphisa, ukucocwa kunye ne-nitriding.
