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. Hauv steelmaking, 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 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. Tsawg aluminium ferrosilicon yog ib qho tshwj xeeb ntawm kev siv ferrosilicon nyob rau hauv xyoo tas los no, nws cov txheej txheem smelting yog complex, siab ntxiv tus nqi ntawm cov khoom, yog cov ferrosilicon manufacturers nquag tshawb nrhiav lub teb. Piv txwv ntawm kev siv ferrosilicon yog raws li nram no:
1) Ntxiv ferrosilicon hmoov los txo cov hmoov nqi ntawm ferrochrome alloy, txoj kev muaj xws li cov kauj ruam hauv qab no: Xaiv cov particle loj generated nyob rau hauv cov txheej txheem crushing ntawm ferrosilicon alloy yog 5? 10mm ferrosilicon hmoov ua raw khoom; Ferrosilicon hmoov yog ntxiv rau cov hlau kub kub thaum lub sij hawm ferrochrome alloy ci txheej txheem, thiab tus nqi ntawm ferrosilicon hmoov ntxiv yog 0.5? 1.0kg / t, thaum ntxiv, 1/3 ntawm tag nrho cov nyiaj ntawm ferrosilicon hmoov yog ntxiv thaum ferrochrome alloy yog ci rau 1/4, 1/3 ntawm tag nrho cov nyiaj ntawm ferrosilicon hmoov yog ntxiv thaum ferrochrome alloy yog ci rau 1/2, thiab 1/3 ntawm tag nrho cov nyiaj ntawm ferrosilicon hmoov yog ntxiv thaum lub ferrochrome alloy yog ci rau 3/4. Ntawm ib sab tes, kev tsim muaj tuaj yeem tiv thaiv kev tsim cov hmoov av thiab cov khoom lag luam ntau ntxiv, txhim kho cov lag luam ferrroalloy, thiab muaj txiaj ntsig zoo heev txo tus nqi ntawm ferrocrome hlau alloy. Ntawm qhov tod tes, ferrosilicon hmoov yog tsim nyob rau hauv cov txheej txheem crushing ntawm ferrosilicon alloy, uas paub txog cov khoom siv rov ua dua tshiab, ua tau raws li cov kev xav tau ntawm kev txuag hluav taws xob thiab kev tiv thaiv ib puag ncig, thiab yuav tsis ua rau ib puag ncig muaj kuab paug thiab lub zog pov tseg, thiab txoj kev yooj yim. los siv, yooj yim thiab yooj yim.
2) Lub pob ferrosilicon yog npaj, uas yog ua los ntawm ferrosilicon raw cov ntaub ntawv thiab cov nplaum. Cov ntaub ntawv raw ntawm ferrosilicon yog ferrosilicon hmoov los yog sib tov ntawm ferrosilicon hmoov thiab nws yog xim hlau silicon hmoov; Cov ntsiab lus ntawm silicon nyob rau hauv ferrosilicon hmoov yog 72-75%, thiab cov ntsiab lus ntawm silicon nyob rau hauv metallic silicon hmoov yog 72-85%. Cov nplaum nplaum yog ua los ntawm dej, quartz xuab zeb, alkali, fluorite, silica hmoov thiab micro-silica hmoov, thiab nws cov qauv yog 3-3.7. Txoj kab uas hla ntawm ferrosilicon hmoov pob yog 10-80mm. Cov khoom lag luam yog cov khoom siv raw ntawm ferrosilicon, tov nrog cov ntawv khi tshwj xeeb siv rau kev tsim khoom, siv cov txheej txheem pelleting, tsis tas yuav rov ua kom sov dua, qhov sib xyaw ntawm txhua yam khoom hauv kev tsim khoom yuav tsis hloov, yog li nws yooj yim los tswj cov ntsiab lus ntawm silicon ntawm cov khoom; ferrosilicon hmoov thiab hlau silicon hmoov siv hauv kev tsim khoom tuaj yeem ua cov hmoov seem tom qab crushing ntawm cov khoom xa tawm, yog li cov peev txheej uas twb muaj lawm hauv Suav teb tau txais kev cawmdim, thiab kev siv kuj yooj yim heev.
