Dab tsi yog cov hau kev rau smelting magnesium?
Tam sim no, muaj ob txoj kev tseem ceeb rau cov magnesium smelting:
1. Electrolysis, uas cuam tshuam lub cev qhuav dej lossis kev daws teeb meem los ntawm cov tshuaj nplaum, lossis dej hiav txwv los ua cov tshuaj molten magnesium, ua raws li cov electrolysis.
2. Thermal txo (Pidgeon cov txheej txheem) Siv Ferrosilicon kom txo cov tshuaj Magnesium los ntawm calcinning carbonate ore.
① electrolysis
Lub hauv paus ntsiab lus ntawm electrolytic magnesium smelting cuam tshuam cov electrolyium coltide ntawm cov kub, decomposing nws mus rau hauv xim hlau magnesium thiab chlorine roj. Dej ntawm cov kub muaj cov nyhuv detental rau cov khoom ntawm cov ntsev tsis zoo. Yog li ntawd, siab -}}} Magnesium chloride yog qhov tseem ceeb rau electrolytic magnesium ntau lawm. Ua raws li cov ntaub ntawv raw siv thiab cov hau kev siv los ua cov txheej txheem tshwj xeeb hauv cov txheej txheem hauv qab no: cov txheej txheem Magniesia, cov txheej txheem AMC, thiab cov txheej txheem norske.
Cov txheej txheem electrolytic yog ib qho kev cog lus siv hom magnesium smilting vim nws cov txheej txheem ntau lawm thiab kev siv hluav taws xob ntau. Tam sim no, tshaj 80% ntawm cov hlau hlau hauv cov hlau nplaum hauv cov teb chaws tsim tau tsim los ntawm electrolysis.
② Pidgeon txheej txheem
Magnesium hlau ntau lawm suav nrog cov txheej txheem elecurehysmic (Pidgeon txheej txheem), thiab cov txheej txheem carbon thermal. Tus txheej txheem Pidgeon yog ib txoj kev tseem ceeb rau kev tsim cov hlau nplaum Magnesium hauv kuv lub tebchaws vim tias nws muaj peev txheej qeeb, tsis muaj peev txheej, cov nqi qis thiab tus nqi qis. Txawm li cas los xij, cov cuab yeej siv tshuab smelting yog tus rov qab los kuj tau noj ntau yam khoom siv thiab lub zog, ua rau muaj kuab paug loj.
Tus txheej txheem Pidgeon cuam tshuam rau cov pa roj magnesium (lossis txhuas) nyob rau hauv muaj cov pa roj calcium nyob rau hauv cov kub thiab lub tshuab nqus dej los ua cov pa hluav taws xob ntau. Lub vapor no sib cais los ntawm cov khoom dicalcium silicate (2Cao tebchaws site (2Cao tebchaws. Txoj kev no tuaj yeem muab faib ua plaub theem: dolomite kev xam xyuas, kev npaj khoom ua raw, txo, thiab kho kom zoo.
