Taw qhia rau Ferrosilicon

Txij li thaum silicon thiab oxygen tau yooj yim synthesized rau hauv silicon dioxide, ferrosilicon feem ntau yog siv los ua deoxidizer hauv steelmaking.

Nyob rau tib lub sijhawm, vim tias muaj cua sov ntau tawm thaum SiO2 tsim tawm, nws kuj tseem muaj txiaj ntsig los ua kom kub ntawm cov hlau molten thaum deoxidizing. Nyob rau tib lub sijhawm, ferrosilicon kuj tuaj yeem siv los ua cov khoom siv alloying ntxiv, uas 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. Ferrosilicon feem ntau yog siv los ua tus neeg sawv cev txo qis hauv ferroalloy ntau lawm thiab kev lag luam tshuaj.

Ferrosilicon yog ib qho tseem ceeb deoxidizer hauv kev lag luam steelmaking. Nyob rau hauv lub teeb steel, ferrosilicon yog siv rau nag lossis daus deoxidation thiab diffusion deoxidation. Cib hlau tseem siv hauv steelmaking ua tus neeg sawv cev alloying. Ntxiv qee qhov nyiaj ntawm silicon rau cov hlau tuaj yeem txhim kho lub zog, hardness thiab elasticity ntawm cov hlau, txhim kho cov hlau nplaum permeability ntawm cov hlau, thiab txo cov hysteresis poob ntawm cov hlau transformer. General steel muaj 0.15% -0.35% silicon, structural steel muaj 0.40% -1.75% silicon, cov cuab yeej steel muaj 0.30% -1.80% silicon, caij nplooj ntoos hlav steel muaj 0.40% -2.80% silicon, stainless acid-resistant steel muaj 0.40% -2.80 % silicon silicon yog 3.40% mus rau 4.00%, thiab kub-resistant steel muaj 1.00% mus rau 3.00% ntawm silicon, thiab silicon steel muaj 2% mus rau 3% los yog ntau tshaj ntawm silicon.



High-silicon ferrosilicon los yog siliceous alloys yog siv nyob rau hauv kev lag luam ferroalloy li txo cov neeg ua hauj lwm rau zus tau tej cov carbon ferroalloys tsawg. Ferrosilicon tuaj yeem siv los ua ib qho inoculant rau ductile hlau thaum ntxiv rau cam khwb cia hlau, thiab tuaj yeem tiv thaiv kev tsim cov carbides, txhawb cov nag lossis daus thiab spheroidization ntawm graphite, thiab txhim kho kev ua haujlwm ntawm cam khwb cia hlau.

Tsis tas li ntawd, ferrosilicon hmoov tuaj yeem siv tau raws li lub sijhawm ncua kev lag luam hauv kev lag luam ntxhia, thiab tuaj yeem siv los ua txheej txheej rau vuam rods hauv kev lag luam vuam pas nrig; high-silicon ferrosilicon tuaj yeem siv los npaj cov khoom siv semiconductor ntshiab silicon hauv kev lag luam hluav taws xob, thiab tuaj yeem siv rau hauv kev lag luam tshuaj los ua silicones, thiab lwm yam.
