Khoom Description
Hlau yog cov khoom siv tseem ceeb hauv lub neej niaj hnub, siv txhua yam los ntawm tsheb thiab khoom siv rau kev tsim kho thiab kev tsim kho vaj tse. Nws yog cov hlau muaj zog thiab ruaj khov, thiab yog li ntawd, qhov kev thov rau cov hlau tsis tu ncua. Txawm li cas los xij, kev tsim cov hlau tuaj yeem yog cov txheej txheem kim, thiab steel mills yeej ib txwm nrhiav txoj hauv kev los cawm cov nqi. Ib txoj hauv kev uas cov mills steel siv yog siv ferrosilicon.
Ferrosilicon yog ib qho hlau uas ua los ntawm cov hlau thiab silicon, nrog cov ntsiab lus siab ntawm silicon nyob ib ncig ntawm 70-80%. Nws yog qhov zoo tshaj plaws ntawm silicon, uas yog qhov tseem ceeb hauv kev tsim cov hlau. Thaum ntxiv rau cov hlau molten, ferrosilicon muab ntau yam txiaj ntsig, xws li kev txhim kho cov hlau lub zog thiab hardness, txo nws cov ntsiab lus melting, thiab txo oxidation.
Ib qho ntawm cov kev siv tseem ceeb ntawm ferrosilicon hauv steelmaking yog ua tus neeg sawv cev deoxidizing. Thaum lub sij hawm tsim cov txheej txheem, molten steel tuaj yeem ua paug nrog oxygen, uas tuaj yeem ua rau cov hlau tsis muaj zog tag nrho. Los ntawm kev ntxiv ferrosilicon rau cov hlau molten, nws reacts nrog oxygen los tsim silica, uas yog ces yooj yim tshem tawm ntawm cov hlau. Cov txheej txheem no txhim kho cov hlau zoo thiab tiv thaiv nws los ntawm kev tawg lossis tsis muaj zog.
Lwm qhov txiaj ntsig ntawm kev siv ferrosilicon hauv steel ntau lawm yog nws lub peev xwm los txo tus nqi tag nrho ntawm cov txheej txheem. Raws li lub hauv paus ntawm silicon, ferrosilicon tuaj yeem hloov lwm yam, kim dua, qhov chaw ntawm cov hlau, xws li silica lossis silicon carbide. Los ntawm kev siv ferrosilicon, steel mills tuaj yeem txo lawv cov nqi tsim khoom yam tsis muaj kev txi zoo.
Tsis tas li ntawd, ferrosilicon pab txhim kho cov khoom ntawm cov hlau. Qhov sib ntxiv ntawm ferrosilicon tuaj yeem txhim kho cov hlau hardness, ua rau nws tiv taus hnav thiab tsim kua muag. Qhov no hardness ntxiv kuj ua rau nws zoo dua rau siv nyob rau hauv high-stress daim ntaub ntawv, xws li nyob rau hauv kev tsim kho los yog hnyav machinery.
Vim nws cov txiaj ntsig ntau, ferrosilicon tau dhau los ua ib feem tseem ceeb ntawm cov txheej txheem steel. Niaj hnub no, steel mills thoob plaws ntiaj teb siv ferrosilicon los tsim cov hlau zoo ntawm tus nqi qis. Qhov tseeb, kev thov thoob ntiaj teb rau ferrosilicon tseem nce ntxiv raws li cov hlau
kev tsim khoom ua ntau dua.
Ntxiv rau nws siv hauv kev tsim cov hlau, ferrosilicon muaj ntau yam kev siv. Piv txwv li, nws yog siv los tsim cov cam khwb cia hlau, nrog rau kev tsim cov ferrosilicon magnesium, ib qho nrov nodularizer siv los tsim cov hlau ductile. Ferrosilicon kuj tseem siv rau hauv kev tsim cov silicon, uas feem ntau yog siv rau hauv ntau yam khoom siv hluav taws xob thiab hnub ci vaj huam sib luag.
Hauv kev xaus, ferrosilicon plays lub luag haujlwm tseem ceeb hauv kev tsim cov hlau. Nws muab ntau yam txiaj ntsig, suav nrog deoxidizing cov hlau, txo tus nqi tag nrho ntawm kev tsim khoom, thiab txhim kho cov hlau cov khoom. Raws li qhov kev thov rau cov hlau txuas ntxiv nce ntxiv, yog li qhov kev thov rau ferrosilicon ib yam nkaus. Steel mills thoob plaws ntiaj teb cia siab rau ferrosilicon los tsim cov hlau zoo ntawm tus nqi pheej yig, ua rau nws yog ib qho khoom siv tseem ceeb hauv kev tsim khoom. Zuag qhia tag nrho, kev siv ferrosilicon tau muaj txiaj ntsig zoo rau kev lag luam steel, ua kom nws ua tau raws li qhov xav tau ntawm cov neeg niaj hnub no thaum tseem txo cov nqi tsim khoom.
