Ferrochrome yog tsim los ntawm ua kom txo qis ntawm cov hlau magnesium chromium oxide nyob rau hauv qhov kub thiab txiasHlau-chromium alloy yog tsim los ntawm kev txo qis ntawm Chromium Ore los ntawm kev siv cov thee thiab coke. Qhov kev txo qis no yuav tsum muaj cua sov uas los ntawm hluav taws xob arc ntawm lub cub tawg.
Chromium ua li cas?
Chromium hlau
Ntshiab chromium yog tsim los ntawm kev txo thermal ntawm Cr2O3 nrog txhuas lossis los ntawm the electrolysis ntawm trivalent chromium solutions Cov txheej txheem aluminothermic pib nrog roasting ntawm nplua ore, dej qab zib, thiab txiv qaub nyob rau hauv huab cua ntawm 1, 100 ° C (2, 000 ° F).
Dab tsi yog ferrochrome ore?
Ferrochrome, lossis ferrochromium (FeCr) yog hom ferroalloy, uas yog, ib qho hlau ntawm chromium thiab hlau, feem ntau muaj 50 txog 70% chromium los ntawm qhov hnyav. Ferrochrome yog tsim los ntawm hluav taws xob arc carbothermic txo ntawm chromite.
Cov ferrochrome yog dab tsi?
Txheej txheem cej luam: Ferrochrome (FeCr) yog an alloy ntawm chromium thiab hlau muaj nyob nruab nrab ntawm 50% thiab 70% chromium Tus tsim khoom od stainless hlau & cov cuab yeej hlau yog cov neeg siv khoom loj tshaj plaws ntawm ferrochrome thiab them chrome. Nws yog chromium uas confers raws li stainless hlau nws zoo kawg li corrosion kuj.
Leej twg yog tus tsim khoom ferrochrome loj tshaj?
South Africa yog lub tsev rau feem coob ntawm lub ntiaj teb cov chromite deposits thiab yog cov loj tshaj plaws ferrochrome thiab chromite ore tsim.
