Kev siv hluav taws xob ntawm smelting 75 ferrosilicon tso nyiaj rau 60-65% ntawm cov nqi tsim khoom; kev siv hluav taws xob ntawm smelting 45 ferrosilicon nyiaj rau 50-55% ntawm cov nqi tsim khoom. Yog li ntawd, txo qis kev siv hluav taws xob yog ib qho ntawm cov yuam sij los txo cov nqi tsim khoom ferrosilicon.
Raws li kev suav ua ntej, kev siv hluav taws xob theoretical rau smelting 75 ferrosilicon yog 6850 txog 7050 degrees, tab sis qhov kev siv hluav taws xob tiag tiag hauv kev tsim khoom yog 8200 txog 9000 degrees, thiab qhov kub poob yog li 16 txog 18% (cov hluav taws xob poob). Nws tuaj yeem pom tias cua sov thiab hluav taws xob poob loj heev. Qhov no muaj ntau yam ua rau kev khiav hauj lwm qib, kev tu cov cuab yeej siv, cov khoom siv raw, cov khoom siv hluav taws xob thiab kev tsim hluav taws xob submerged. Cia peb tham txog qee qhov teeb meem ntsig txog kev tsim khoom:
1. Ua tib zoo tuav lub tshuab hluav taws xob, ntxig cov electrode kom sib sib zog nqus thiab tsis tu ncua rau hauv cov khoom siv hauv lub tshuab hluav taws xob, yog li nthuav cov crucible thiab ua kom kub kub, tswj cov huab cua zoo permeability ntawm cov khoom nto, thiab sib zog ua kom tsis txhob muaj hluav taws kub thiab tawg ntawm cov khoom, thiab txo qhov kub poob.
2. Txhim kho kev saib xyuas cov khoom siv thiab cov khoom siv hluav taws xob kom txo tau lub sijhawm thermal kaw. Ferrosilicon smelting yog kev tsim khoom tas mus li. Yog tias lub cub tawg tau kaw ntev ntev los yog cov sij hawm muaj ntau, nws yuav siv sij hawm ntev kom rov qab mus rau qhov cub zoo li qub. Piv txwv li, yog tias lub qhov cub raug kaw rau ib teev, nws yuav siv li ob teev los ua kom lub cub tawg kom sov kom txog thaum nws mus txog rau hauv cov cua sov li qub, ib lub cub hluav taws xob tsawg dua yuav raug tsim tawm. Yog tias lub qhov cub kaw tau ob teev, ob lub qhov cub hlau yuav ploj. Chav tsev fais fab noj ntawm ferrosilicon yog khi kom nce.
3. Cov khoom siv raw. Concentrate yog qhov tseem ceeb hauv kev txo cov hwj huam siv hluav taws xob ntawm ferrosilicon.
Lub coke siv rau smelting ferrosilicon yuav tsum muaj qhov haum particle loj thiab siab tsis kam ntawm qhov kub thiab txias los pab txhawb kev sib sib zog nqus electrode insertion.
Silica yuav tsum muaj qhov zoo thermal stability los tiv thaiv kev tawg ntxov ntxov ntawm qhov kub thiab txias thiab tseem ua rau huab cua permeability ntawm cov khoom nto. Yog tias muaj kev tso cai, silica yuav tsum tau ntxuav nrog dej.
Cov tshuaj muaj pes tsawg leeg ntawm ntau yam raw khoom yuav tsum tsim nyog.
4. Xaiv lub tshuab hluav taws xob tsim nyog. Qhov nruab nrab voltage siab dhau lawm thiab lub zog input siab. Txawm li cas los xij, vim tias cov electrodes tau muab tso rau hauv qhov ntiav, muaj ntau qhov kub thiab txias thiab lub zog siv hluav taws xob nce. Yog tias qhov hluav taws xob thib ob tsawg dhau, txawm hais tias qhov hluav taws xob poob qis dua, lub zog hluav taws xob qis dua, qhov kub ntawm lub cub tawg yog qis, thiab cov zis tawm tsawg dua, uas tsis yog qhov tsim nyog rau kev txo cov khoom siv hluav taws xob. Yog li ntawd, yuav tsum tau xaiv qhov tsim nyog theem nrab voltage rau smelting.
5. Txhim kho qhov rov ua dua tshiab ntawm cov hlau rov qab, tshem tawm cov khoom pov tseg, ua kom cov zis ntau ntxiv, thiab txo qis kev siv hluav taws xob.
