Kev smelting ntawm qis-qib ferroalloys siv crucibles pib nyob rau hauv 1860. Tom qab ntawd, smelting ntawm ferromanganese thiab ferrosilicon uas muaj tsawg tshaj li 12% silicon ntsiab lus tau tsim los siv blast furnaces. Nyob nruab nrab ntawm 1890 thiab 1910, kev tsim cov ferroalloys siv hluav taws xob arc furnaces pib hauv Fabkis. H. Moissan tau ua qhov kev sim ua haujlwm ntawm qhov nyuaj-kom- txo cov khoom siv hluav taws xob arc rauv, thiab PLTH Roult tau siv nws rau kev tsim khoom. Lub sijhawm ntawd, coke thiab charcoal tau siv los ua cov neeg ua haujlwm txo kom txo tau cov ore uas cuam tshuam, thiab cov khoom lag luam feem ntau siab -carbon.
Tom qab xyoo 1920, kom ua tau raws li qhov xav tau ntawm kev txhim kho qib siab - cov hlau zoo thiab cov hlau tsis muaj steel, ib theem tshiab ntawm qis- carbon ferroalloy tau pib. Ntawm qhov tod tes, raws li cov txheej txheem aluminothermic tau npaj los ntawm K. Goldschmidt hauv xyoo 1898, kev smelting ntawm qee cov pa roj carbon - dawb ferroalloys thiab cov hlau ntshiab siv cov txheej txheem aluminothermic tau tsim; ntawm qhov tod tes, ib txoj kev desilication refining yog tsim los oxidize silicon-muaj alloys nyob rau hauv ib lub cub hluav taws xob. Vim yog tus nqi ntau lawm ntawm cov txheej txheem aluminothermic, desilication refining txoj kev tau dav siv ntau dua. Txawm niaj hnub no, nruab nrab-carbon, qis{11}}carbon, thiab ultra-low-carbon ferrochrome, nruab nrab-carbon thiab qis-carbon ferromanganese, thiab hlau manganese feem ntau yog ua kom zoo dua siv txoj kev no. Qhov kub- sib tov txoj kev rau refining ferrochrome yuav tsum sib tov kua ore thiab txiv qaub yaj nrog silicon{18}}chromium alloy los ntawm kub sib tov kom ceev cov tshuaj tiv thaiv; qhov no yog kev txhim kho ntxiv ntawm txoj kev desilication refining. Tsis tas li ntawd, electrolysis yog siv los tsim cov ntshiab alloying additives (xws li metallic manganese), thiab lub tshuab nqus tsev decarburization yog siv los tsim ultra-qis-carbon ferrochrome nrog cov pa roj carbon tsawg heev. Nyob rau hauv xyoo tas los no, cov txheej txheem rau refining ferrochrome thiab ferromanganese siv cov pa ntshiab tshuab kuj tau tsim.
