Kev siv ntawm Silicon Calcium
Calcium thiab silicon muaj kev sib raug zoo nrog oxygen. Tshwj xeeb tshaj yog calcium hlau muaj ib tug muaj zog affinity nrog oxygen thiab muaj zog affinity nrog sulfur thiab nitrogen. Yog li ntawd, calcium silicon yog ib qho zoo tagnrho deoxidizer thiab desulfurizer. Silicon alloys muaj lub peev xwm deoxidizing muaj zog, uas pab cov khoom deoxidized yooj yim ntab thiab tawm, tab sis kuj tuaj yeem txhim kho steel kev ua tau zoo hauv plasticity, cuam tshuam toughness, thiab fluidity, ductility. Tam sim no, calcium silicon alloy tuaj yeem hloov aluminium rau qhov kawg deoxidation.
Nws yog siv rau hauv kev tsim cov hlau nrog cov qib sib txawv thiab cov alloys tshwj xeeb. Nws kuj tseem siv tau los ua inoculant thiab additive hauv kev lag luam cam khwb cia hlau.
1. Compound deoxidizer thiab desulfurizer.
2. Cua sov tus neeg saib xyuas siv nyob rau hauv converter steelmaking Rhiav.
3. Nws tuaj yeem siv los ua inoculant rau cam khwb cia hlau.
4. Ua ib qho ntxiv los tsim cov hlau nplaum.
Kev tsim khoom ntawm Silicon Calcium
Lub ferro silicon calcium alloy tuaj yeem tau txais los ntawm silica, txiv qaub, thiab coke nyob rau hauv ib qho kev txo qis ntawm 1500-1800 degrees. Silicon calcium alloy yog npaj los ntawm kev txo cov silicon dioxide thiab calcium oxide nrog ib tug carbonaceous txo tus neeg sawv cev nyob rau hauv lub txo hluav taws xob rauv. Cov txheej txheem ntau lawm ntawm ferro silicon calcium: ib-kauj ruam txoj kev thiab ob-kauj ruam txoj kev.
Ib txoj hauv kev yog txo cov silica thiab limestone nrog carbon los tsim calcium silicon alloy hauv lub cub hluav taws xob. Nws tau muab faib ua cov txheej txheem pub mis sib xyaw thiab txheej txheej pub mis.
Txoj kev ob kauj ruam yog thawj zaug tsim calcium carbide (los yog high-carbon ferrosilicon) nyob rau hauv lub cub hluav taws xob, thiab ces siv calcium carbide, silica, thiab coke (los yog siv high-carbon ferrosilicon thiab txiv qaub) los tsim silicon calcium alloy nyob rau hauv lwm yam. hluav taws xob rauv.
Tsis tas li ntawd, raws li cov khoom tiav, muaj ob txoj kev npaj los ntawm kev siv cov cub tawg sib txawv.
1. High-cov ntsiab lus silicon calcium alloy cov khoom, feem ntau yog tsim los ntawm electrode furnaces
Nta:
a: Silicon calcium alloy cov khoom uas muaj ntau dua specifications yuav ua tau.
b: Cov khoom zoo yog ruaj khov thiab muaj ob peb impurities.
2. Cov ntsiab lus nruab nrab thiab qis silicon calcium alloy cov khoom yog tsim los ntawm nruab nrab zaus furnaces.
Nta:
a: Feem ntau tsim nruab nrab thiab qis specification silicon calcium alloy khoom.
b: Tus nqi tsim khoom tsawg, thiab cov zis tuaj yeem tswj tau yooj yim.
