FERRO SILICON 75 nrog cov yam ntxwv zoo

Ferrosilicon 75 feem ntau yog tsim los ntawm silicon thiab hlau, nrog cov ntsiab lus silicon ntau dua lossis sib npaug li 75%. Tsis tas li ntawd, nyob ntawm cov qib tshwj xeeb (xws li 75A, 75B, 75C, thiab lwm yam), nws kuj tseem tuaj yeem muaj lwm yam kab kawm xws li txhuas, calcium, magnesium, manganese, phosphorus, thiab lwm yam, tab sis lawv cov ntsiab lus raug tswj nruj me ntsis. Ferrosilicon 75 feem ntau yog nyob rau hauv daim ntawv thaiv los yog granular, nrog siab ceev thiab hardness. Nws cov xim feem ntau yog tsaus grey lossis dub, nyob ntawm cov txheej txheem tsim khoom thiab cov khoom siv raw.

Ferrosilicon 75 feem ntau yog tsim los ntawm smelting hauv lub cub hluav taws xob siv coke, steel scraps, thiab quartz (los yog silica) ua raw khoom. Thaum lub sij hawm tsim cov txheej txheem, tsis xws li raw khoom piv, smelting kub thiab lub sij hawm yuav tsum tau nruj me ntsis tswj los xyuas kom meej cov khoom zoo thiab kev ua tau zoo. Lub ferrosilicon 75 tej zaum yuav nyob rau hauv daim ntawv ntawm blocks, granules los yog hmoov. Cov ntawv sib txawv ntawm ferrosilicon tuaj yeem muaj qhov sib txawv ntawm daim ntawv thov thiab kev siv. Feem ntau hais lus, ferrosilicon 75 qib nrog qis impurity cov ntsiab lus thiab cov ntsiab lus silicon ruaj khov yuav kim dua. Qhov no yog vim lawv cov txheej txheem ntau lawm yog qhov nyuaj thiab cov khoom siv raw yuav tsum nruj dua.

Ferrosilicon 75 feem ntau yog siv los ua deoxidizer hauv cov txheej txheem steelmaking. Vim yog cov tshuaj lom neeg zoo ntawm silicon thiab oxygen, Ferrosilicon 75 tuaj yeem tshem tawm cov pa oxygen los ntawm cov hlau molten, yog li txhim kho cov purity thiab zoo ntawm cov hlau. Ferrosilicon 75 kuj tseem tuaj yeem muab ntxiv rau cov hlau ua cov khoom siv hlau los txhim kho cov khoom ntawm cov hlau. Ntxiv rau qhov tsim nyog ntawm silicon tuaj yeem txhim kho lub zog, hardness thiab hnav tsis kam ntawm cov hlau, yog li Ferrosilicon 75 yog dav siv hauv smelting steel xws li cov qauv hlau, cov cuab yeej steel, caij nplooj ntoos hlav steel thiab silicon steel rau transformers. Nyob rau hauv cam khwb cia hlau ntau lawm, Ferrosilicon 75 feem ntau yog siv los ua inoculant. Nws tuaj yeem txhawb cov nag lossis daus thiab spheroidization ntawm graphite, yog li txhim kho cov qauv thiab cov khoom ntawm cam khwb cia hlau. Tshwj xeeb tshaj yog nyob rau hauv zus tau tej cov ductile hlau, Ferrosilicon 75 plays lub luag hauj lwm tseem ceeb. Ntxiv rau qhov ua ib qho inoculant, Ferrosilicon 75 kuj tuaj yeem siv los ua tus neeg sawv cev spheroidizing hauv qee kis los txhim kho cov khoom ntawm cov hlau cam khwb cia. Hauv ferroalloy ntau lawm, Ferrosilicon 75 feem ntau yog siv los ua tus neeg sawv cev txo qis. Vim muaj cov tshuaj lom neeg muaj zog ntawm silicon thiab oxygen thiab cov pa roj carbon tsawg ntawm high-silicon ferrosilicon, ferrosilicon 75 yog ib qho siv los txo tus neeg sawv cev hauv kev tsim cov pa roj carbon tsawg ferroalloys.
