Txij li calcium muaj kev sib raug zoo nrog oxygen, sulfur, hydrogen, nitrogen thiab carbon nyob rau hauv molten steel, calcium silicon alloy yog tsuas yog siv rau deoxidation, degassing thiab fixation ntawm leej faj nyob rau hauv molten hlau. Calcium silicon ua rau muaj zog exothermic nyhuv thaum ntxiv rau molten hlau.

Lub ferrosilicon granule inoculant yog tsim los ntawm kev tawg ferrosilicon rau hauv me me ntawm ib qho kev faib ua feem thiab lim lawv los ntawm ib lub sieve nrog ib qho mesh loj.

Thaum refining, cov txheej txheem kuj yuav tsum tau luv luv thiab tsis muaj cov khoom pov tseg raug tsim. Tag nrho cov xwm txheej yuav tsum tau txiav txim siab thiab tswj tau yooj yim.



Vim tias lub taphole yog qhov nyuaj rau kev tswj xyuas thaum smelting 45 ferrosilicon, lub taphole yuav tsum tau zoo thaum resmelting. Raws li tus nqi ntawm cov hlau molten nce, ua hauj lwm nyob rau hauv pem hauv ntej ntawm lub cub tawg yuav tsum muaj zog tshwj xeeb.

Ib qho ntawm cov haujlwm tseem ceeb ntawm lub smelter yog ua kom zoo ntawm kev txiav txim siab ntawm lub cub tawg kom raug thiab kho thiab tuav cov cua sov kom sai li sai tau kom cov cua sov cov xwm txheej nyob rau hauv ib txwm muaj.

Ferrosilicon yog dav siv nyob rau hauv steelmaking kev lag luam, ferroalloy kev lag luam, cam khwb cia hlau kev lag luam thiab lwm yam kev lag luam sectors.

Muaj ntau yam khoom siv silicon, xws li ferro silicon, hlau silicon, hlau silicon hmoov, silicon carbide, thiab lwm yam.
