Kev ua ntawm micro carbon ferrochrome hmoov

Cov txheej txheem ntau lawm ntawm nruab nrab, qis thiab micro-carbon ferrochrome los ntawm cov txheej txheem Suav tsoos feem ntau hu ua "peb-kauj ruam txoj kev" los yog electrosilicon-thermal txoj kev: uas yog, thawj tus tsim high-carbon ferrochrome los ntawm kev siv peb lub cub hluav taws xob, thiab tom qab ntawd ua silicon-chromium alloy los ntawm kev siv high-carbon ferrochrome li raw khoom nyob rau hauv lub thib ob platform, thiab ces tsim nruab nrab-qis thiab micro-carbon ferrochrome los ntawm kev siv silicon-chromium alloy ua raw khoom nyob rau hauv lub thib peb _L . Cov teb chaws txawv teb chaws feem ntau siv "Boren txoj kev", kuj xav tau 3 lub cub hluav taws xob, tab sis qhov sib txawv yog qhov cub hluav taws xob sab nraum "invert", kom chromium ore, txiv qaub yaj thiab silicon chromium alloy tag nrho cov tshuaj tiv thaiv los tsim cov qis, micro carbon ferrochrome. Ob txoj kev no yog ua raws li lub hauv paus ntsiab lus uas qhov kev sib raug zoo ntawm silicon thiab oxygen ntau dua li cov pa roj carbon monoxide, thiab qhov txo qis ntawm CrZO hauv chromium ore: tom qab, vim tias cov pa roj carbon tsawg ntawm silicon chromium alloy, qis thiab micro-carbon ferrochrome. muaj 0.5 feem pua ​​rau 0.06 feem pua ​​carbon tau. Hydrogen thiab oxygen refining txheej txheem yog txheej txheem ntawm kev tsim cov hlau tsis zoo. Cov cuab yeej siv yog AOD rauv. Cov txheej txheem no yog nchuav cov hlau molten coarsed hauv lub cub hluav taws xob rau hauv lub qhov cub AOD.

Cov ntaub ntawv tseem ceeb ntawm electrosilicothermal smelting ntawm micro - carbon ferrochrome yog chromium ore, silicon chromium alloy thiab txiv qaub. Ib txhia kuj ntxiv fluorite thiab hlau nplai. Chromium ore yuav tsum yog qhuav, huv si block ore los yog mloog zoo nrog ib tug block loj ntawm tsawg tshaj li 50 hli. Xaiv silicon chromium alloy nrog cov ntsiab lus sib txawv raws li qib ntawm micro-carbon ferrochrome hmoov smelted.
