Kev tshuaj xyuas luv luv ntawm cov laj thawj rau cov ntsiab lus qis ntawm ferrosilicon smelted

Ferrosilicon yog cov hlau alloy uas muaj hlau thiab silicon. Niaj hnub no, ferrosilicon muaj ntau yam kev siv. Ferrosilicon kuj tseem siv tau los ua cov khoom siv alloying additive thiab yog dav siv hauv cov hlau tsis tshua muaj hlau, lub caij nplooj ntoos hlav steel, cov kabmob hlau, cov hlau tsis muaj cua sov thiab hluav taws xob silicon steel. Ntawm lawv, ferrosilicon feem ntau yog siv los ua tus neeg sawv cev txo qis hauv ferroalloy ntau lawm thiab kev lag luam tshuaj. Txawm li cas los xij, ntau tus neeg tsuas yog nkag siab txog kev siv ferrosilicon thiab tsis nkag siab txog kev smelting ntawm ferrosilicon thiab cov teeb meem uas yuav pom thaum smelting. Txhawm rau kom txhua tus neeg nkag siab txog ferrosilicon, ferrosilicon cov neeg muag khoom yuav luv luv txheeb xyuas cov laj thawj rau cov ntsiab lus qis hauv ferrosilicon.

Qhov laj thawj tseem ceeb yog vim li cas cov smelted ferrosilicon muaj cov ntsiab lus qis dua yog tias thaum cov tuam txhab smelt ferrosilicon, lawv siv coke ua tus neeg sawv cev txo qis, kom tus kheej ci electrodes uas yooj yim rau carburize siv coke cib los tsim cov tapholes thiab Flow hlau trough. , qee zaum siv cov hmoov graphite los npog cov pwm pwm, siv cov pa roj carbon monoxide coj cov qauv ua kua, thiab lwm yam. Hauv luv luv, thaum lub sij hawm smelting. ferrosilicon los ntawm cov tshuaj tiv thaiv nyob rau hauv lub cub tawg kom txog rau thaum cov hlau yog tapping, muaj ntau yam kev sib cuag nrog carbon thaum lub sij hawm pouring txheej txheem. Qhov siab dua cov ntsiab lus ntawm silicon hauv ferrosilicon, nws cov ntsiab lus qis dua. Thaum cov ntsiab lus silicon hauv ferrosilicon ntau dua li ntawm 30%, feem ntau ntawm cov pa roj carbon hauv ferrosilicon muaj nyob rau hauv lub xeev ntawm silicon carbide (SiC). Silicon carbide yog yooj yim oxidized thiab txo los ntawm silicon dioxide los yog silicon monoxide nyob rau hauv lub crucible. Silicon carbide muaj me ntsis solubility hauv ferrosilicon, tshwj xeeb tshaj yog thaum kub qis, thiab nws yooj yim rau precipitate thiab ntab. Yog li ntawd, silicon carbide tshuav nyob rau hauv ferrosilicon yog tsawg heev, yog li cov pa roj carbon ntsiab lus ntawm ferrosilicon yog tsawg heev.
