Hnub Christmas
Lub sijhawm Christmas nyob ntawm no.Kuv vam tias koj muaj lub xyoo tshiab zoo.Thov kom txhua hnub tuav cov sij hawm zoo siab rau koj.
Smelt
High silicon ferrosilicon yog smelted nyob rau hauv ib tug txo hluav taws xob rauv nrog ib tug carbon txheej, siv silica, steel filings (los yog hlau nplai), thiab coke ua raw cov ntaub ntawv.Hluav taws xob rauv ferrosilicon smelting yog ib txoj kev tsis muaj slag, thiab cov ntaub ntawv raw yuav tsum huv si thiab tsis muaj av nkos, xuab zeb, thiab lwm yam impurities.Ntxiv cov ntoo chips thiab thee rau cov khoom siv rau hauv qhov cub tuaj yeem txhim kho nws cov kev ua tau zoo.Thaum lub sij hawm smelting txheej txheem, qhov saum npoo ntawm cov khoom yog feem ntau ua rau crust thiab "stinging" (surface spraying), thiab nws yog ib qhov tsim nyog yuav tau nquag "phaus rauv".Lub cub tawg ua silicon hlau txhua 2-4 teev thiab pwm nws mus rau hauv ingots nrog ib tug tuab ntawm tsawg tshaj li 100 millimeters.Lub smelting ntawm ferrosilicon feem ntau txais yuav qhib hluav taws xob rauv.Nyob rau hauv xyoo tas los no, txhawm rau tiv thaiv ib puag ncig muaj kuab paug, "tsawg hood" lossis "semi enclosed" hluav taws xob furnaces tau nquag siv, uas yooj yim rau kev rov qab los ntawm lub zog cua sov thiab tshem tawm cov pa taws thiab plua plav;Kev tsim cov silicon ferrosilicon siab (muaj ntau dua 75% silicon) feem ntau yog ua los ntawm kev siv lub tshuab hluav taws xob tig kom txo tau qhov cub tawg.
Lub hom phiaj
1. 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 li cov hlau, yooj yim rau yaj thiab smelt, thiab muaj kev ua haujlwm zoo tshaj plaws thiab zoo dua seismic tsis kam tshaj hlau.Tshwj xeeb tshaj yog ductile hlau, nws cov cuab yeej cuab tam ncav cuag lossis mus txog cov hlau.Ntxiv ib qho nyiaj ntawm ferrosilicon rau cam khwb cia hlau tuaj yeem tiv thaiv kev tsim cov carbides hauv hlau, 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 (pab kom precipitate graphite) thiab spheroidizing tus neeg sawv cev.
2. 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 steelmaking.Hauv steelmaking, ferrosilicon yog siv rau nag lossis daus deoxygenation thiab diffusion deoxygenation.Cib cam khwb cia hlau kuj tseem siv los 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 rau nws cov hlau nplaum permeability, thiab txo cov hysteresis poob ntawm transformer steel.Tsawg aluminium ferrosilicon yog ib hom tshwj xeeb ntawm ferrosilicon uas tau tshwm sim nyob rau xyoo tas los no.Nws cov txheej txheem smelting yog complex thiab tus nqi ntxiv ntawm cov khoom yog siab, uas yog ib qho chaw nquag tshawb nrhiav los ntawm ntau yam ferrosilicon manufacturers.
