Isithombe Esivelele Semishini Yesithando Sokuncibilikisa I-Ferrochrome Enekhabhoni Eningi — Imishini Yesithando Sokuncibilikisa I-Ferrochrome Ene-Carbon Eningi

Incazelo yomkhiqizo

Izindlela zokukhiqiza i-ferrochrome enekhabhoni ephezulu zifaka phakathi indlela ye-electric furnace, indlela ye-shaft furnace (blast furnace), indlela ye-plasma kanye nendlela yokunciphisa ukuncibilika. Indlela ye-shaft furnace manje ikhiqiza kuphela i-chromium alloy ephansi (Cr < 30%), okuqukethwe okuphezulu kwe-chromium (njenge-Cr> 60%) yenqubo yokukhiqiza i-shaft furnace kusesesigabeni socwaningo; izindlela ezimbili zokugcina ziyahlolwa enkambisweni evelayo; ngakho-ke, iningi elikhulu le-ferrochrome enekhabhoni ephezulu yezentengiselwano kanye ne-ferrochrome eyenziwe kabusha isetshenziswa ekukhiqizweni kwendlela ye-electric furnace (mineral furnace).

XHUMANA MANJE

Ukuncibilikisa isithando sikagesi kunezici ezilandelayo

(1) Isithando sikagesi sisebenzisa ugesi, umthombo wamandla ohlanzekile kakhulu. Eminye imithombo yamandla efana namalahle, i-coke, uwoyela ongahluziwe, igesi yemvelo, njll. izoletha ngokungenakugwenywa izinto ezingcolile ezihambisana naso enkambisweni yensimbi. Izithando zikagesi kuphela ezingakhiqiza ama-alloy ahlanzekile kakhulu.

(2) Ugesi uwukuphela komthombo wamandla ongathola izimo zokushisa eziphakeme ngokungahleliwe.

(3) Isithando sikagesi singabona kalula izimo ze-thermodynamic ezifana nomfutho we-oxygen ongaphelele kanye nomfutho we-nitrogen ongaphelele odingwa yizindlela ezahlukahlukene zokusabela kwe-metallurgical njengokunciphisa, ukucwenga kanye nokukhipha i-nitriding.
