Kev taw qhia luv luv:
Ferrochrome yog ib qho tseem ceeb alloy additive rau steelmaking, uas yog tsim los ntawm chromium thiab hlau. Chromite rau smelting ferrochrome feem ntau yuav tsum muaj Cr2O340 ~ 50%, thiab qhov piv ntawm chromium rau hlau yog ntau dua 2.8. Nyob rau hauv xyoo tas los no, ib tug loj npaum li cas ntawm "them qib ferrochrome" muaj 50% chromium yog tsim, nrog ore muaj Cr2O3 thiab tsawg piv ntawm chromium rau hlau.
Tsawg carbon ferrochrome yog siv nyob rau hauv zus tau tej cov uas tsis muaj carbon structural steel, chromium hlau, alloy structural steel. Chromium steel feem ntau yog siv los tsim cov iav, iav shafts, thiab lwm yam. Chromium manganese silicon steel feem ntau siv los tsim cov kiv cua siab, valve phaj, thiab lwm yam.
Muaj ob txoj kev smelting tseem ceeb ntawm cov pa roj carbon tsawg ferrochrome: siab carbon ferrochrome refining txoj kev thiab hluav taws xob silicothermic txoj kev.
Cov txheej txheem ntau lawm yog tseem siv hluav taws xob silicothermic txoj kev. Nyob rau hauv cov xwm txheej ntawm kev ua kom yooj yim slag hauv hluav taws xob rauv, silicon hauv silicon chromium alloy yog siv los txo cov oxide ntawm nruab nrab chromium thiab hlau, thiaj li tsim cov pa roj carbon ferrochrome tsawg.
