Ferrochrome, cyangwaferrochromium(FeCr) ni ubwoko bwa ferroalloy, ni ukuvuga umusemburo wa chromium na fer, muri rusange urimo chromium 50 kugeza 70% kuburemere.

Ferrochrome ikorwa namashanyarazi arc carbothermic kugabanya chromite.Ibyinshi mubisohoka kwisi bikorerwa muri Afrika yepfo, Qazaqistan no mubuhinde, bifite umutungo munini wa chromite.Kwiyongera kwamafaranga biva muburusiya n'Ubushinwa.Umusaruro wibyuma, cyane cyane ibyuma bitagira umuyonga hamwe na chromium ya 10 kugeza kuri 20%, ni umuguzi munini kandi ukoresha ferrochrome.

Ikoreshwa

Kurenga 80% byisiferrochromeikoreshwa mugukora ibyuma bitagira umwanda.Muri 2006, hakozwe Mt 28 z'ibyuma bitagira umwanda.Ibyuma bitagira umwanda biterwa na chromium kubigaragara no kurwanya ruswa.Impuzandengo ya chrome yibirimo mubyuma bidafite ingero.18%.Irakoreshwa kandi mukongeramo chromium mubyuma bya karubone.FeCr yo muri Afrika yepfo, izwi nka "charge chrome" kandi ikomoka muri Cr irimo ubutare burimo karuboni nkeya, ikoreshwa cyane mubikorwa byibyuma bidafite ingese.Ubundi, karubone ndende ya FeCr ikomoka mumabuye yo murwego rwohejuru aboneka muri Qazaqistan (hamwe nahandi hantu) ikoreshwa cyane mubikorwa byinzobere nkibikoresho byubwubatsi aho igipimo kinini cya Cr / Fe hamwe nuburinganire bwibindi bintu (sulfure, fosifore, titanium nibindi) .) nibyingenzi kandi kubyara ibyuma byarangiye bibera mumatara mato mato ya arc ugereranije nitanura rinini.

Umusaruro

Umusaruro wa ferrochrome nigikorwa cyo kugabanya carbothermic igikorwa kubushyuhe bwinshi.Amabuye ya Chromium (oxyde ya Cr na Fe) agabanywa namakara na kokiya kugirango akore fer-chromium.Ubushyuhe bwiyi reaction burashobora guturuka muburyo butandukanye, ariko mubisanzwe biva mumashanyarazi arc yakozwe hagati yinama ya electrode munsi yitanura hamwe nitanura.Iyi arc ikora ubushyuhe bwa 2.800 ° C (5,070 ° F).Muburyo bwo gushonga, amashanyarazi menshi arakoreshwa, bigatuma umusaruro uhenze cyane mubihugu aho amashanyarazi ari menshi.

Gufata ibikoresho biva mu itanura bibaho rimwe na rimwe.Iyo ferrochrome ihagije imaze kwegeranya mu ziko, umwobo wa robine urakingurwa hanyuma umugezi wicyuma gishongeshejwe hamwe nigitonyanga cyihuta kumanuka mukibindi gikonjesha.Ferrochrome ikomera muri casting nini zajanjaguwe kugurishwa cyangwa gutunganywa neza.

Ubusanzwe Ferrochrome ishyirwa mubikorwa nubunini bwa karubone na chrome irimo.Ubwinshi bwa FeCr yakozwe ni "charge chrome" yo muri Afrika yepfo, hamwe na karubone ndende nigice cya kabiri kinini gikurikirwa nimirenge mito ya karubone nkeya hamwe na karubone hagati.
