Txawm tiassilicon carbidethiabferrosiliconyog ob qho khoom tseem ceeb hauv thaj teb ntawm silicon-raws li metallurgy/cov khoom siv, lawv cov haujlwm tseem ceeb, kev ua tau zoo, thiab kev siv cov xwm txheej sib txawv heev. SiC alloy dominates cov ntaub ntawv refractory thiab siab -kawg hluav taws xob vim nws "siab hardness thiab kub tsis kam," thaum ferro silicon tsom rau cov tub ntxhais txuas ntawm steel smelting nrog nws "tsawg nqi thiab alloying / deoxidation functions." Qhov ob yog complementary es tsis hloov pauv.

Nco tseg:Qhov "siab hardness thiab kub tsis kam" ntawm silicon carbide thiab "alloying thiab low cost" ntawm ferrosilicon ntxiv rau ib leeg thiab tsis muaj kev hloov ncaj qha rau kev ua haujlwm. "Kev ua haujlwm deoxidation thiab kev sib koom ua ke yooj yim ntawm silicon" yuav tsum muaj nyob rau hauv metallurgical scenarios yog cov txiaj ntsig tseem ceeb uas silicon carbide tsis muaj.
Cov laj thawj yog vim li cas silicon carbide tsis tau hloov tag nrho ferrosilicon
Nqi
Cov txheej txheem kev npaj ntawm silicon carbide yog qhov nyuaj, yuav tsum tau siab -kev kho kub thiab kev tswj kom meej, yog li tus nqi kuj siab. Hauv qhov sib piv, tus nqi tsim khoom ntawm ferrosilicon tej zaum yuav qis dua, uas yog qhov tseem ceeb hauv qee qhov kev siv.
Daim Ntawv Thov Scope
Txawm hais tias silicon carbide muaj qhov zoo hauv qee qhov chaw uas muaj qhov kub thiab txias thiab kev tiv thaiv corrosion, xws li cov khoom siv refractory, ceramic khoom, thiab lwm yam, ferrosilicon tseem muaj nws qhov tshwj xeeb siv hauv electronics, semiconductors thiab lwm yam lag luam vim nws cov khoom siv hluav taws xob zoo thiab kev ua haujlwm zoo.
Kev ua tau zoo sib txawv
Txawm hais tias silicon carbide muaj kev ua tau zoo hauv qee yam, xws li siab -kub stability thiab hardness, nws yuav tsis zoo li ferrosilicon nyob rau hauv cov nqe lus ntawm conductivity, machinability, thiab lwm yam.
Kev ua lag luam Inertia
Ferrosilicon, raws li cov khoom siv ib txwm siv, tau siv dav hauv ntau lub teb, thiab nws cov txheej txheem tsim khoom thiab cov saw hlau yog cov paub tab. Yog li ntawd, ib qho ntawm cov laj thawj vim li cas silicon carbide tsis tau siv dav hauv qee daim ntawv thov yog tias muaj kev tsim khoom thiab kev siv network ntawm ferrosilicon hauv khw.
Txawm hais tias silicon carbide muaj qee qhov tshwj xeeb zoo, ferrosilicon tseem yog qhov pheej yig thiab ua tau zoo xaiv hauv cov ntawv thov tshwj xeeb.
