1. Kev tsim cov ferrosilicon
Ferrosilicon yog cov hlau alloy uas muaj hlau thiab silicon.Ferrosilicon yog cov hlau-silicon alloy ua los ntawm coke, steel scraps, quartz (los yog silica) ua raw khoom thiab smelted nyob rau hauv lub cub hluav taws xob.Txij li thaum silicon thiab oxygen yooj yim ua ke los ua silica, ferrosilicon feem ntau yog siv los ua deoxidizer hauv steelmaking.Nyob rau tib lub sijhawm, txij li SiO2 tso tawm ntau cov cua sov thaum nws 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 tseem tuaj yeem siv los ua cov khoom siv alloying ntxiv thiab tau 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.
2. Daim ntawv thov ntawm ferrosilicon
Ferrosilicon yog dav siv hauv kev lag luam steel, kev lag luam casting thiab lwm yam kev lag luam.
Ferrosilicon yog ib qho tseem ceeb deoxidizer hauv kev lag luam steel.Nyob rau hauv lub teeb steel, ferrosilicon yog siv rau nag lossis daus deoxidation thiab diffusion deoxidation.Cib hlau kuj tseem siv los ua tus neeg sawv cev alloying hauv steelmaking.Ntxiv qee qhov nyiaj ntawm silicon rau cov hlau tuaj yeem txhim kho lub zog, hardness thiab elasticity ntawm cov hlau, txhim kho cov permeability ntawm steel, thiab txo cov hysteresis poob ntawm transformer steel.Cov hlau dav dav muaj 0.15% -0.35% silicon, cov qauv hlau muaj 0.40% -1.75% silicon, cov cuab yeej hlau muaj 0.30% -1.80% silicon, lub caij nplooj ntoos hlav steel muaj 0.40% -2.80% silicon, stainless acid-resistant steel muaj 3.40% -4.00% silicon, thiab cov hlau kub-resistant muaj 1.00% ~ 3.00% silicon.Silicon steel muaj 2% mus rau 3% silicon lossis siab dua.
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.Ntxiv ferrosilicon rau cam khwb cia hlau tuaj yeem siv los ua inoculant ntawm nodular cam khwb cia hlau, thiab tuaj yeem tiv thaiv kev tsim cov carbide, txhawb cov nag lossis daus ntawm graphite, thiab txhim kho kev ua haujlwm ntawm cam khwb cia hlau.
Tsis tas li ntawd, ferrosilicon hmoov tuaj yeem siv los ua lub sijhawm ncua kev lag luam hauv kev lag luam ntxhia, thiab ua cov txheej rau vuam rods hauv kev lag luam vuam pas nrig.High silicon hlau silicon tuaj yeem siv los npaj cov khoom siv semiconductor ntshiab silicon hauv kev lag luam hluav taws xob, thiab tuaj yeem siv los tsim silicone hauv kev lag luam tshuaj.
Hauv kev lag luam steelmaking, kwv yees li 3 ~ 5kG 75% ntawm ferrosilicon yog siv rau ib tuj ntawm cov hlau tsim.
