Ferrosilicon yog ib tug neeg sawv cev tseem ceeb siv nyob rau hauv kev lag luam steelmaking los txhim kho kom zoo thiab ua tau zoo ntawm cov hlau. Kev xaiv kom tsim nyog, kev faib tawm, thiab cov ntawv thov ntawm ferrosilicon yog qhov tseem ceeb kom ntseeg tau cov txiaj ntsig zoo. Hauv qab no yog cov lus qhia ntxaws ntxaws txog kev yuav siv ferrosilicon zoo nyob hauv cov txheej txheem steelmaking.
1. Xaiv Ferrosilicon
Thaum xaiv 75 # ferrosilicon (muaj 75% silicon), nws yog ib qho tseem ceeb kom ntseeg tau tias nws cov kev xav tau ntawm cov txheej txheem steel. Qhov tseem ceeb ua kom ntsuas tau muaj xws li:
Tshuaj lom neeg cov tshuaj:Xyuas kom cov ferrosilicon muaj cov ntsiab lus silicon raws li cov silicon (nyob ib ncig ntawm 75%) thiab cov qib qis xws li txhuas, phosphorus, thiab leej faj. Cov impurities no tuaj yeem cuam tshuam tsis zoo rau qhov zoo ntawm cov khoom kawg steel kawg.
Lub cev lub cev:Lub ferrosilicon yuav tsum muaj cov qauv coj mus ib yam thiab muaj kev ywj pheej ntau dhau plua plav lossis nplua, uas tuaj yeem ua rau kev sib tw ua haujlwm thiab tsis sib haum xeeb.
Particle loj faib:Xaiv ferrosilicon nrog cov khoom siv loj me me kom ntseeg tau thiab cov tshuaj tiv thaiv hauv Molten hlau. Feem ntau, ib qho me me ntawm 10-50mm yog cov nyiam rau cov ntawv thov steelmaking.
Kev nyiam huv:Ua kom cov ferrosilicon yog pub dawb los ntawm cov kev paug xws li ya raws, lossis lwm cov ntaub ntawv txawv teb chaws, raws li cov no tuaj yeem qhia tej yam tsis zoo rau hauv cov hlau.
Los ntawm ua tib zoo xaiv siab siab - Zoo 75 tuaj yeem txhim kho kev ua tau zoo ntawm cov khoom siv hlau thiab txhim kho cov khoom kawg.
2. Kev sib faib thiab cov txheej txheem sib xyaw
Qhov kev faib ua feem ntawm ferrosilicon ntxiv rau cov hlau molten rau ntawm cov kev xav tau ntawm steelmaking, xws li cov khoom lag luam silicon nyob rau hauv cov khoom kawg thiab hom hlau uas tsim tawm. Ua raws li cov theem no rau qhov raug ua kom raug thiab sib xyaw:
Laib cov feem pua uas yuav tsum tau ua: Txiav txim tus nqi 75 # ferrosilicon xav tau raws li cov phiaj Silicon cov ntsiab lus thiab ntim ntawm Molten hlau. Qhov kev xam no yuav tsum xav txog cov ntsiab lus silicon ntawm ferrosilicon thiab kev ua tau zoo ntawm cov tshuaj tiv thaiv.
Cov hau kev sib xyaw:Muaj ntau txoj hauv kev los qhia ferrosilicon rau hauv cov hlau molten, suav nrog:
Online Stirring:Ntxiv ferrosilicon ncaj qha mus rau hauv lub molten hlau thaum txhib kom paub tseeb tias kev faib tawm thiab kev sib cais sai.
Txhaj Txoj Kev:Siv cov khoom tshwj xeeb kom txhaj cov ferrosilicon hais rau hauv cov hlau Molten, tso cai rau kev tswj hwm kom meej thiab muaj kev tiv thaiv zoo.
Tshob ntxiv:Ntxiv ferrosilicon rau txoj kev pw thaum tapping los txhawb kev sib xyaw cov kev sib xyaw thiab cov tshuaj tiv thaiv nrog cov hlau Molten.
Txoj kev xaiv yuav tsum ua kom ntseeg tau tias Ferrosilicon reacts tag nrho nrog cov hlau molten, ua tiav qhov xav tau desoxidation, kev ua kom zoo, thiab cov teebmeem kev ua haujlwm ntxiv.
3. Kev tiv thaiv kev ua haujlwm
Thaum siv 75 # ferrosilicon hauv statmaking steelmaking, nws yog qhov tseem ceeb kom ua raws li kev nyab xeeb thiab kev ua haujlwm los ua kom muaj kev nyab xeeb thiab muaj kev nyab xeeb:
Tus tswjfub ntxiv:Ntxiv Ferrosilicon rau Molten Steel maj mam thiab tusyees kom zam dhau kev ua rau muaj kev sib cais lossis ua txhaum. Qhov no txo qis kev pheej hmoo ntawm cov xwm txheej thiab ua kom cov neeg ua haujlwm muaj kev nyab xeeb.
Tswj kub:Saib xyuas qhov kub ntawm Molten Steel kom ntseeg tau tias nws yog nyob rau hauv qhov kev pom zoo rau ferrosilicon ntxiv. Kev kub ntxhov heev tuaj yeem ua rau cov kev tawm tsam sai, thaum tsis muaj kub tsis txaus yuav ua rau muaj kev cuam tshuam tsis tiav.
Khoom Tiv Thaiv Khoom:Cov neeg ua haujlwm yuav tsum hnav cov hnab looj tes tiv thaiv tus kheej (PPE), suav nrog cov hnab looj tes tiv thaiv, thiab tiv thaiv cov khaub ncaws raug mob los ntawm cov roj ntsha kom sov thiab molten hlau txaws.
Ib puag ncig tswj:Ua kom ntseeg tau qhov cua thiab cov plua plav tswj tau yog qhov chaw, raws li cov plua plav ferrosilicon tuaj yeem ua rau kev noj qab haus huv thiab kev nyab xeeb.
Los ntawm adhering rau cov kev ceev faj no, koj tuaj yeem ua kom zoo tshaj plaws ntawm ferrosilicon thaum tswj kev nyab xeeb ib puag ncig ua haujlwm.
4. Cov txiaj ntsig ntawm kev siv 75 # ferrosilicon
Kev siv ntawm 75 # ferrosilicon hauv statmaking steelmaking muaj ntau qhov zoo, suav nrog:
Deoxidation:Ferrosilicon tau tshem tawm cov pa oxygen los ntawm cov hlau molten, txo qhov tsim ntawm oxides thiab txhim kho cov hlau huv.
Alloying:Nws nce cov ntsiab lus silicon hauv steel, txhim kho nws lub zog, tawv, thiab hnav kom haum thiab hnav.
Microstructure refinement:Ferrosilicon pab kho cov qauv nplej ntawm cov hlau, ua rau muaj cov khoom siv txhim kho cov khoom siv thiab kev ua tau zoo.
Los ntawm ua raws li cov lus qhia no rau kev xaiv, kev faib tawm, thiab ua kom zoo dua cov txheej txheem steelmaking thiab tsim cov khoom lag luam siab zoo steel. Yog xav tau kev pab ntxiv lossis nug txog ferrosilicon, xav tiv tauj peb pab neeg txhawb nqa.
