Kev siv Chromite

Ferrochrome muab faib ua cov pa roj carbon ntau ferrochrome raws li cov ntsiab lus sib txawv, suav nrog kev thauj khoom qib ferrochrome (C Tsawg dua lossis sib npaug rau 10%), nruab nrab carbon ferrochrome (C Tsawg dua lossis sib npaug rau 4.0 %), qis carbon ferrochrome (C Tsawg dua lossis sib npaug rau 0.5%), micro-carbon ferrochrome (C Tsawg dua lossis sib npaug li 0.15%), thiab lwm yam. Feem ntau siv yog chromium silicon alloy, chromium nitride thiab lwm yam. Ferrochrome feem ntau yog siv los ua cov khoom siv hlau ntxiv hauv steelmaking thiab siv los ntxiv rau hauv cov txheej txheem refining lig ntawm steelmaking. Smelting stainless hlau thiab lwm yam tsawg carbon steel, yuav tsum siv tsawg thiab micro carbon ferrochrome, yog li refined ferrochrome ntau lawm kuj loj-scale kev loj hlob. Vim yog kev txhim kho ntawm cov txheej txheem steelmaking, thaum AOD txoj kev (saib refining sab nraum lub cub tawg) yog siv los tsim stainless hlau thiab lwm yam steel qib, carbon ferrochrome (feem ntau them qib ferrochrome) yog loaded rau hauv lub cub tawg, yog li tsuas yog tsawg thiab micro- carbon ferrochrome yog ntxiv nyob rau hauv lub sij hawm tom qab los kho cov muaj pes tsawg leeg, yog li tam sim no lub hom phiaj ntawm ferrochrome ntau lawm yog refining carbon ferrochrome.Qhov kev taw qhia ntawm lub "Steel Industry Development Policy" yog ib qho kev tshwm sim loj hauv kev txhim kho Tuam Tshoj txoj kev lag luam steel, uas yuav ua lub luag haujlwm tseem ceeb hauv kev txhim kho yav tom ntej ntawm Tuam Tshoj txoj kev lag luam steel, thiab yog lub hauv paus tseem ceeb rau kev txhawb nqa kev noj qab haus huv ntawm kev lag luam steel.
