Qhov sib txawv tseem ceeb ntawm calcination thiab sintering yog tias calcination yog cua sov ntawm cov hlau ore kom tshem tawm impurities, whereas sintering yog cua sov ntawm hlau ore rau weld ua ke me me ntawm ib tug hlau.
Calcination thiab sintering yog ob yam txheej txheem pyrometallurgical. Txawm li cas los xij, ob qho tib si cov txheej txheem no suav nrog cov cua sov ntawm cov khoom siv hlau mus rau qhov kub uas qis dua qhov melting point ntawm cov hlau.
Calcination yog dab tsi?
Calcination yog txheej txheem pyrometallurgical ntawm cua sov cov hlau ore nyob rau hauv muaj huab cua tsawg lossis oxygen. Nyob rau hauv cov txheej txheem no, peb yuav tsum tau kom sov lub ore mus rau ib tug kub ntawm nws melting point. Cov txheej txheem no tseem ceeb heev kom tshem tawm cov impurities volatile. Tsis tas li ntawd, lub npe calcination los ntawm Latin lub npe vim nws daim ntawv thov loj - cua sov ntawm calcium carbonate ores.
Daim duab 01: Calciner
Calcination yog ua tiav nyob rau hauv lub reactor, uas yog ib tug cylindrical qauv; peb hu nws lub calciner. Nyob rau hauv no reactor, lub calcination yog ua nyob rau hauv kev tswj tej yam kev mob. Cov pa roj carbon dioxide yog tsim thiab tso tawm thaum lub sij hawm calcination thiab calcium carbonate hloov mus rau hauv calcium oxide. Cov txheej txheem no tsuas yog ua kom tshem tawm cov impurities tsis haum. Txawm li cas los xij, qee zaum lub cub tawg yog siv rau calcination vim tias nws cuam tshuam rau cov khoom cua sov kom kub siab heev.
Ib qho piv txwv ntawm calcination yog kev tsim cov txiv qaub los ntawm limestone. Hauv cov txheej txheem no, limestone tau muab qhov kub thiab txias uas txaus los tsim thiab tso cov pa roj carbon dioxide. Txiv qaub yog tsim nyob rau hauv ib qho yooj yim hmoov mob.
Sintering yog dab tsi?
Sintering yog txheej txheem pyrometallurgical uas me me ntawm cov hlau yog welded ua ke. Nws yog ua los ntawm kev siv lub tshav kub uas nyob hauv qab lub melting point ntawm cov hlau. Kev siv cua sov tshem tawm cov kev ntxhov siab sab hauv los ntawm qee yam khoom siv. Tsis tas li ntawd, cov txheej txheem no yog qhov tseem ceeb hauv kev tsim cov hlau. Kev siv cov txheej txheem sintering suav nrog kev tsim cov duab nyuaj, tsim cov alloys thiab muaj peev xwm ua haujlwm yooj yim nrog cov hlau uas muaj cov ntsiab lus melting siab.
Hauv kev tsim khoom, peb yuav tsum siv lub txaj ntawm cov hmoov hlau los ntawm cov hlau ore. Cov hlau no yuav tsum tau tov nrog coke ua ntej siv. Tom qab ntawd lub txaj ntawm hlau yog ignited siv lub roj burner. Tom qab ntawd qhov kub hnyiab tau dhau los ntawm kev taug kev grate. Ntawm no, peb yuav tsum kos cua los ntawm lub grate thiaj li yuav pib ib qho combustion cov tshuaj tiv thaiv. Tom qab ntawd muaj cua sov heev, uas ua rau cov khoom me me ntawm cov hlau tsim cov pob. Cov lumps no tsim nyog yuav tsum tau hlawv rau hauv qhov cub tawg kom thiaj li tsim tau cov hlau. Tsis tas li ntawd, cov txheej txheem sintering yog qhov tseem ceeb hauv kev tsim cov ceramic thiab iav ib yam nkaus.
Qhov txawv ntawm Calcination thiab Sintering yog dab tsi?
Calcination thiab sintering yog ob yam txheej txheem pyrometallurgical. Qhov sib txawv tseem ceeb ntawm calcination thiab sintering yog tias calcination yog cua sov ntawm cov hlau ore kom tshem tawm impurities, whereas sintering yog cua sov ntawm hlau ore rau weld ua ke me me ntawm cov hlau. Qhov tshwm sim ntawm calcination yog tshem tawm cov impurities ntawm ib tug hlau ore thaum rau sintering nws yog qhov vuam ntawm hais ntawm hlau kom tau ib daim.
Cov ntawv qhia hauv qab no qhia txog qhov sib txawv ntawm calcination thiab sintering.
Summary – Calcination vs Sintering
Calcination thiab sintering yog ob yam txheej txheem pyrometallurgical. Qhov sib txawv tseem ceeb ntawm calcination thiab sintering yog tias calcination yog cua sov ntawm cov hlau ore kom tshem tawm impurities, whereas sintering yog cov cua sov ntawm cov hlau ore rau weld ua ke me me ntawm ib tug hlau.
