Dab tsi yog kev siv thiab tsim cov ferro silicon?

Ferrosilicon yog cov hlau alloy uas muaj hlau thiab silicon. Ferrosilicon tseem hu ua ferrosilicon. Nws 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. Nws yog dav siv nyob rau hauv steel kev lag luam, foundry kev lag luam thiab lwm yam industrial ntau lawm.
Siv ua deoxidizer thiab alloying tus neeg sawv cev hauv kev lag luam steelmaking. Txhawm rau kom tau txais cov hlau uas tsim nyog cov tshuaj muaj pes tsawg leeg thiab ua kom cov hlau zoo, deoxidation yuav tsum tau ua nyob rau theem kawg ntawm steelmaking. Cov tshuaj affinity ntawm silicon thiab oxygen yog loj heev, yog li ferrosilicon yog ib tug muaj zog deoxidizer rau steelmaking rau nag lossis daus thiab diffusion. deoxidation.
Ntxiv qee qhov nyiaj ntawm silicon rau cov hlau tuaj yeem txhim kho lub zog, hardness thiab elasticity ntawm cov hlau. Yog li ntawd, nws yog dav siv nyob rau hauv smelting structural steel (muaj 0.40-1.75% silicon), cuab yeej steel (muaj SiO.30-1.8%), thiab caij nplooj ntoos hlav steel. (muaj SiO.
Nyob rau tib lub sijhawm, kev txhim kho cov duab ntawm kev suav nrog thiab txo cov ntsiab lus ntawm cov khoom siv roj hauv cov hlau molten yog cov cuab yeej tshiab zoo los txhim kho steel zoo, txo cov nqi, thiab txuag hlau. Nws yog tshwj xeeb tshaj yog haum rau deoxidation yuav tsum tau ntawm nruam casting molten steel. Kev xyaum tau ua pov thawj tias ferrosilicon tsis yog tsuas yog ua tau raws li qhov yuav tsum tau ua ntawm deoxidation ntawm steelmaking, tab sis kuj muaj desulfurization kev ua tau zoo thiab muaj qhov zoo ntawm lub ntiajteb txawj nqus loj thiab muaj zog nkag mus rau lub zog.
