FeSi Description
Ferroalloy yog hais txog cov hlau uas muaj ib lossis ntau dua hlau lossis tsis yog hlau thiab hlau.Ferrosiliconyog ib qho alloy ntawm silicon thiab hlau. Raws li peb txhua tus paub, 75% Ferro-Silicon yog ib qho tseem ceeb raw khoom rau steelmaking thiab casting. Fe Silicon 75 siv nyob rau hauv steelmaking tuaj yeem txhim kho lub cev, tshuaj, thiab cov khoom siv hlau thiab castings, yog li txhim kho lawv qhov zoo. Raws li ib qho tseem ceeb raw khoom rau metallurgical industries xws li hlau, ferrosilicon cov khoom ua si lub luag hauj lwm tseem ceeb nyob rau hauv niaj hnub kev lag luam kev loj hlob. Kev lag luam steelmaking, casting, thiab ferroalloy yog cov lag luam loj tshaj plaws rau ferrosilicon, siv ntau tshaj 90% ntawm ferrosilicon txhua xyoo.
Cov txheej txheem tsim khoom ntawm fe silicon suav nrog smelting nrog coke, steel seem, thiab quartz (los yog silica) ua raw khoom nyob rau hauv lub cub hluav taws xob. Nyob rau hauv ib txwm Fesi Ferrosilicon refining, silicon raug txo los ntawm silica uas muaj SiO2. Metallurgical coke feem ntau yog siv los ua tus neeg sawv cev txo qis, thaum cov hlau seem ua haujlwm ua tus hloov kho rau 75% Fe Si Foundry Qib. Qhov tseeb, cov tshuaj tiv thaiv mechanism ntawm Fe Silicon yog qhov nyuaj heev.
Txawm hais tias cov kws tshawb fawb tau tawm tswv yim txog kev txo qis sib txawv, muaj ob peb lub ntsiab lus tsis txaus ntseeg, suav nrog kev tsim thiab decomposition ntawm cov khoom nruab nrab xws li silicon carbide thiab silicon monoxide thaum lub sij hawm smelting. Silicon monoxide plays lub luag haujlwm tseem ceeb hauv tag nrho cov txheej txheem txo silica.Silicon Ferro feem ntau yog siv los ua deoxidizer hauv steelmaking, qhov twg nws yog siv rau nag lossis daus thiab diffusion deoxidation. Nws tseem ua haujlwm ua tus neeg sawv cev alloying hauv steelmaking.
Ntxiv qee qhov nyiaj ntawm silicon rau cov hlau tuaj yeem txhim kho nws lub zog, hardness, thiab elasticity, ua kom nws cov hlau nplaum permeability, thiab txo qhov sib nqus hysteresis poob hauv cov hlau transformer. Nyob rau tib lub sijhawm, SiO2 tsim kom muaj cua sov ntau, uas yog qhov zoo rau kev nce qhov kub ntawm cov hlau molten thaum deoxidation. Ferrosilicon kuj tseem tuaj yeem siv los ua cov khoom siv alloying ntxiv, dav siv hauv cov hlau tsis tshua muaj hlau, cov hlau sib xyaw, cov hlau hlau, cov kabmob hlau, cov hlau tsis muaj cua sov, cov hlau hluav taws xob, thiab lwm yam. ferroalloy ntau lawm thiab tshuaj lom neeg kev lag luam.
Ntxiv mus, ferrosilicon tuaj yeem siv los ua ib qho inoculant los txhim kho cov khoom ntawm cov hlau nplaum. Nws kuj tseem ua haujlwm raws li lub sijhawm ncua hauv kev lag luam ntxhia. Ferrosilicon hmoov tuaj yeem siv rau hauv kev tsim cov vuam fluxes.
