Cov txheej txheem ntau lawm ntawm silicon calcium
Cov Khoom Siv Raw: Kev tsim cov tshuaj calcium pib nrog ua tib zoo xaiv cov khoom nyoos. Siab - Zoo Quartzite, Rich nyob rau silicon dioxide (sitio₂), yog cov khoom siv tseem ceeb. Txiv qaub (calcium oxide, cao), muab tau los ntawm limestone, yog lwm qhov tseem ceeb. Cov pa roj carbon - raws li txo cov neeg sawv cev, xws li Coke, kuj tseem yuav tsum tau ua.
Smelting hauv hluav taws xob arc rauv: Cov txheej txheem smelting tsuas yog siv sij hawm hluav taws xob tshuab hluav taws xob. Nyob rau hauv cov kev mob siab - tej yam kev mob kub, feem ntau yog tshaj 1600 degree, cov pa roj carbon hauv cov calcium oxide thiab silicon dioxide. Cov tshuaj tiv thaiv tseem ceeb tuaj yeem yog sawv cev raws li: \ (cao + sio {3}} C \ ovearrow Casi {}}} uparrow \). Qhov tshuaj tiv thaiv no yog endeothermic mas enditectating lub siab - ib puag ncig kub los ntawm hluav taws xob rauv taws.
Kev kho kom zoo thiab kev tswjhwm zoo: Tom qab thawj zaug smelting, tus crude calcium silicon yog kev ua kom zoo ntxiv. Qhov no suav nrog cov txheej txheem los kho cov ntawv sib xyaw, thiab xyuas kom meej tias cov khoom kawg raws li cov qauv kev nruj me nyuam zoo los ntawm kev lag luam sib txawv. Tswj kev tswj kom zoo yog tau ua tiav rau txhua theem los lav qhov sib xws thiab kev ntseeg tau ntawm cov khoom.
Cov ntawv thov ntawm silicon calcium
Steelmaking: Hauv kev lag luam hlau, calcium silicon tau siv dav ua deoxidizer thiab desulfurizer. Los ntawm kev ntxiv calcium silicon rau Molten Steel silicon rau Molten Steel silicon rau Molten thiab Sulphur impurities yuav raug tshem tawm tau zoo. Cov txheej txheem Deagidation txhim kho cov hlau cov khoom siv, xws li lub zog thiab tawv, thaum lub sij hawm desulfurization txhim kho nws corrosion tsis kam thiab machinesility tsis kam thiab machinesility.
CIA MAACK NTAU LAWM: Rau nrum hlau tsim, calcium silicon pab ua tus neeg sawv cev graphitizing. Nws txhawb nqa kev tsim ntawm graphite hauv cam khwb cia hlau, uas yog qhov tseem ceeb rau kev txhim kho cov khoom siv ductility, thermal conductivity, thiab machinesility conductivity, thiab machinesility conductivity, thiab machinesility conductivity, thiab machinesility conductivity, thiab machinancability. Tsis tas li ntawd, nws pab ua kom ua kom tsis txhob ua kom zoo cov qauv sib dhos ntawm cov hlau cam khwb cia ntawm cov hlau cam khwb cia, ua kom zoo dua qub - ua yeeb yam duab pob zeb.
Aluminium thiab tsis yog - cov lag luam hlau: Hauv kev lag luam txhuas, calcium silicon qee zaum ntxiv rau aluminium alloys. Ntxiv qhov no tuaj yeem hloov kho Alloy's Microy Microy Microstructure, txhim kho nws cov kev ua tau zoo, kev siv tshuab lub zog, thiab xeb kuj. Nws kuj pom cov ntawv thov hauv lwm cov txheej txheem xov tooj hlau tsis zoo, qhov chaw nws tau siv los kho cov tshuaj lom neeg thiab cov khoom ntawm cov khoom kawg.
