Ferrosiliconyog siv los ua ib qhov chaw ntawm silicon los txo cov hlau los ntawm lawv cov oxides thiab deoxidize hlau thiab lwm yam ferrous alloys.Qhov no tiv thaiv kev poob ntawm cov pa roj carbon monoxide los ntawm cov hlau molten (hu ua thaiv cov cua sov);ferromanganese, spiegeleisen, calcium silicides, thiab ntau lwm yam ntaub ntawv siv rau tib lub hom phiaj.[4]Nws tuaj yeem siv los ua lwm yam ferroalloys.Ferrosilicon kuj tseem siv rau kev tsim cov silicon, corrosion-resistant thiab high-temperature-resistant ferrous silicon alloys, thiab silicon steel rau electromotors thiab transformer cores.Hauv kev tsim cov hlau cam khwb cia, ferrosilicon yog siv rau inoculation ntawm cov hlau kom nrawm graphitization.Hauv arc vuam, ferrosilicon tuaj yeem pom hauv qee cov txheej txheem electrode.

Ferrosilicon yog lub hauv paus rau kev tsim cov prealloys xws li magnesium ferrosilicon (MgFeSi), siv los tsim cov hlau nplaum.MgFeSi muaj 3-42% magnesium thiab me me ntawm cov hlau tsis tshua muaj hauv ntiaj teb.Ferrosilicon kuj tseem yog ib qho tseem ceeb ntxiv rau cam khwb cia hlau rau kev tswj cov ntsiab lus ntawm silicon.

Magnesium ferrosiliconyog instrumental nyob rau hauv tsim ntawm nodules, uas muab ductile hlau nws saj zawg zog khoom.Tsis zoo li grey cam khwb cia hlau, uas tsim graphite flakes, ductile hlau muaj graphite nodules, los yog pores, uas ua rau tawg yooj yim dua.

Ferrosilicon kuj tseem siv rau hauv cov txheej txheem Pidgeon los ua magnesium los ntawm dolomite.Kev kho mob ntawm high-siliconferrosiliconnrog hydrogen chloride yog lub hauv paus ntawm kev lag luam synthesis ntawm trichlorosilane.

Ferrosilicon kuj tseem siv nyob rau hauv qhov sib piv ntawm 3-3.5% hauv kev tsim cov nplooj ntawv rau kev sib nqus ntawm cov hluav taws xob hloov hluav taws xob.

Hydrogen ntau lawm

Ferrosilicon yog siv los ntawm cov tub rog kom sai sai tsim hydrogen rau balloons los ntawm txoj kev ferrosilicon.Cov tshuaj tiv thaiv tshuaj siv sodium hydroxide, ferrosilicon, thiab dej.Lub tshuab hluav taws xob me me kom haum rau hauv lub tsheb thauj khoom thiab tsuas yog xav tau me me ntawm lub zog hluav taws xob, cov khoom siv ruaj khov thiab tsis tuaj yeem tawg, thiab lawv tsis tsim hydrogen kom txog thaum sib xyaw.Cov txheej txheem tau siv txij li Kev Tsov Rog Thoob Ntiaj Teb thib 1. Ua ntej no, cov txheej txheem thiab purity ntawm hydrogen tiam uas cia siab rau cov chav hla cov hlau kub yog qhov nyuaj rau tswj.Thaum nyob rau hauv cov txheej txheem "silicol", lub nkoj hnyav hlau yog ntim nrog sodium hydroxide thiab ferrosilicon, thiab thaum kaw, cov dej tswj tau ntxiv;Lub dissolving ntawm hydroxide heats qhov sib tov mus txog 200 ° F (93 ° C) thiab pib cov tshuaj tiv thaiv;sodium silicate, hydrogen thiab chav dej yog tsim.
