Blast furnace txoj kev ntawmsiab carbon ferromanganese
High-carbon ferromanganese yog thawj zaug tsim nyob rau hauv lub qhov cub tawg nrog cov zis siab thiab tus nqi qis. Nws tseem siv dav hauv tsev thiab txawv teb chaws. kuv lub teb chaws Shanxi Dongfang Resources Development Co., Ltd.
Txoj kev blast furnace yog ntxiv manganese ore, coke, txiv qaub thiab lwm yam khoom siv rau hauv qhov cub tawg rau smelting kom tau blast furnace ferromanganese uas muaj 52% ~ 76% manganese / 0.4% ~ 0. 6 phosphor. Txij li qhov sib txawv ntawm qhov cub tawg thiab hluav taws xob rau smelting high-carbon ferromanganese yog qhov sib txawv ntawm cov cua sov, cov qauv ntawm lub cub tawg, geometry thiab kev ua haujlwm ntawm ob lub cub tawg yog qhov sib txawv, tab sis cov ntsiab lus ntawm smelting high-carbon ferromanganese nyob rau hauv lub ob lub qhov cub zoo ib yam.
Txawm li cas los xij, ob lub qhov cub siv tib lub manganese ore rau smelting, yog li cov ntsiab lus phosphorus ntawm cov khoom tau txais txawv. Cov khoom siv hluav taws xob tawg yog {{0}}.07% ~ 0.11% siab dua cov khoom siv hluav taws xob. Qhov no yog vim hais tias tus nqi ntawm coke nyob rau hauv tus nqi muaj pes tsawg leeg ntawm blast furnace smelting yog 5 mus rau 6 lub sij hawm ntawm hluav taws xob rauv smelting, yog li ntau phosphorus nyob rau hauv lub coke yog pauv mus rau hauv lub alloy, thiab lub cub tawg kub thaum lub sij hawm blast furnace smelting yog qis dua, yog li ntawd. Thaum lub sij hawm smelting txheej txheem volatilization ntawm phosphorus yog li 10% qis dua li ntawm hluav taws xob rauv.
