Kev txheeb xyuas qhov zoo ntawm cov pa roj carbon ferro chrome hmoov

High carbon ferrochrome raws li kev yuav khoom loj ntawm cov khoom, nws yog ib qho tseem ceeb heev los txheeb xyuas nws qhov zoo lossis qhov phem. High carbon ferrochrome ntau lawm xav tau ferroalloy raw cov ntaub ntawv yog chromium ore, coke thiab silica, thiaj li yuav kho cov slag hom, yuav tsum tau ntxiv ib tug npaum li cas ntawm dawb tshauv los yog dolomite, siab carbon ferrochrome manufacturers rau raw cov ntaub ntawv yog heev siab, yuav tsum tau siab. cov ntsiab lus ntawm cov khoom muaj txiaj ntsig, kev ua haujlwm zoo, qhov loj me me, thiab kev txuag hluav taws xob zoo heev thiab kev txo qis.
