Kev siv Ferrosilicon yog dab tsi?

Ferrosiliconyog dav siv nyob rau hauv industrial ntau lawm xws li steel kev lag luam thiab cov foundry kev lag luam. Lawv haus ntau tshaj 90% ntawm ferrosilicon. Ntawm ntau qib ntawm ferrosilicon,75% ferrosilicon hmoovyog qhov siv ntau tshaj plaws. Hauv kev lag luam steel, txog 3-5kg ntawm75% ferrosilicon hmoovyog siv rau txhua tuj ntawm steel tsim.

(1) Siv los ua deoxidizer thiab alloy hauv kev lag luam steelmaking

Ntxiv qee qhov nyiaj ntawm silicon rau cov hlau tuaj yeem txhim kho lub zog, hardness thiab elasticity ntawm cov hlau, ua kom cov hlau nplaum permeability ntawm cov hlau, thiab txo cov hysteresis poob ntawm transformer steel. 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. Silicon thiab oxygen muaj cov tshuaj lom neeg muaj zog, yog li ferrosilicon muaj zog los nag thiab diffusion deoxidation nyhuv ntawm oxides hauv cov hlau.

Ntxiv qee qhov nyiaj ntawm silicon rau hlau tuaj yeem txhim kho lub zog, hardness thiab yooj ntawm cov hlau. Yog li ntawd, ferrosilicon kuj tseem siv los ua cov hlau thaum smelting steel qauv (muaj SiO300-70%), cov cuab yeej steel (muaj SiO.30-1.8%), caij nplooj ntoos hlav steel (muaj SiO00-2.8%) thiab silicon steel rau transformers (muaj silicon. 2.81-4.8%). Tsis tas li ntawd, nyob rau hauv kev lag luam steel, ferrosilicon hmoov feem ntau yog siv los ua cov khoom cua sov rau steel ingots los txhim kho qhov zoo thiab rov qab tus nqi ntawm steel ingots los ntawm kev ua kom zoo dua ntawm cov yam ntxwv uas olefins tuaj yeem tso tawm ntau cov cua sov ntawm qhov kub thiab txias.

(2) Siv ua inoculant thiab spheroidizer hauv kev lag luam cam khwb cia hlau

Cam khwb cia hlau yog cov khoom siv hlau tseem ceeb hauv kev lag luam niaj hnub no. Nws yog pheej yig dua cov hlau, yooj yim rau yaj, muaj kev ua tau zoo casting, thiab tiv taus av qeeg ntau dua li cov hlau, tshwj xeeb tshaj yog cov hlau, uas nws cov cuab yeej cuab tam ncav cuag lossis mus txog qhov kev coj tus cwj pwm ntawm cov hlau. Ntxiv ib qho nyiaj ntawm ferrosilicon rau cam khwb cia hlau tuaj yeem tiv thaiv kev tsim cov carbides hauv hlau thiab txhawb cov nag lossis daus thiab spheroidization ntawm graphite. Yog li ntawd, nyob rau hauv zus tau tej cov ductile hlau, ferrosilicon yog ib qho tseem ceeb inoculant (uas pab cov nag lossis daus ntawm graphite) thiab spheroidizer.

(3) Siv los ua tus neeg sawv cev txo qis hauv kev tsim cov hlau dub

Tsis tsuas yog ua silicon thiab oxygen muaj cov tshuaj lom neeg zoo heev, tab sis cov ntsiab lus carbon ntawm high-silicon ferrosilicon kuj tsawg heev. Yog li ntawd, high-silicon ferrosilicon (los yog siliceous alloy) yog ib qho uas feem ntau siv los txo tus neeg sawv cev hauv kev tsim cov pa roj carbon tsawg hauv kev lag luam ferroalloy. Ferrosilicon tuaj yeem muab ntxiv rau cam khwb cia hlau ua cov hlau tsis muaj zog, thiab tuaj yeem tiv thaiv kev tsim cov carbides, txhawb cov nag lossis daus thiab spheroidization ntawm graphite, thiab txhim kho kev ua haujlwm ntawm cam khwb cia hlau.

(4) Lwm yam kev sivferro silicon

Hauv av lossis atomized ferrosilicon hmoov tuaj yeem siv los ua lub sijhawm ncua kev lag luam hauv kev lag luam ntxhia thiab ua cov txheej txheem electrode hauv kev lag luam electrode. High-silicon ferrosilicon tuaj yeem siv los tsim cov khoom lag luam xws li organic silicon hauv kev lag luam tshuaj, los npaj cov khoom siv hluav taws xob ntshiab silicon hauv kev lag luam hluav taws xob, thiab tsim cov organic silicon hauv kev lag luam tshuaj. Hauv kev lag luam hlau, kwv yees li 3 mus rau 5 kilograms ntawm 75% ferrosilicon tau noj rau txhua tuj ntawm cov hlau tsim.

Txheej txheem cej luam ntawm Ferrosilicon

Ferrosiliconyog ib qho alloy ntawm hlau thiab silicon. Ferrosilicon yog hlau-silicon alloy smelted nyob rau hauv lub cub hluav taws xob siv coke, seem hlau, thiab quartz (los yog silica) ua raw khoom. Feem ntau cov ntaub ntawv ntawm ferrosilicon muaj xws li ferrosilicon hais, ferrosilicon hmoov, thiab ferrosilicon slag. Cov qauv tshwj xeeb suav nrog ferrosilicon 75, ferrosilicon 70, ferrosilicon 65, thiab ferrosilicon 45. Cov lus qhia tshwj xeeb yog muab faib raws li qhov sib txawv impurity cov ntsiab lus hauv ferrosilicon, thiab txhua qhov tshwj xeeb muaj nws tus kheej siv sib txawv.

Cov txheej txheem ntau lawm Ferrosilicon

CovferrosiliconCov txheej txheem tsim khoom yog txo cov xuab zeb lossis silicon dioxide (Si) nrog coke / thee (C), thiab tom qab ntawd hnov ​​​​mob nrog hlau (Fe) muaj nyob hauv cov pov tseg. Cov pa roj carbon hauv cov thee yuav tsum tau deoxidized, tawm hauv cov khoom siv silicon thiab hlau.
Ferrosilicon ntau lawm tuaj yeem siv lub tshuab hluav taws xob submerged arc rau yaj quartz nrog cov hlau seem thiab txo tus neeg sawv cev los tsim cov kua dej kub, uas tau sau rau hauv lub txaj xuab zeb. Tom qab txias, cov khoom yog tawg mus rau hauv me me pieces thiab ntxiv crushed rau hauv qhov yuav tsum tau loj.
