Dab tsi yog qhov txawv ntawm ferro manganese thiab manganese?
Manganese yog cov khoom siv tshuaj nrog lub cim Mn thiab atomic tooj 25. Nws yog cov hlau hloov pauv uas muaj cov xim grey-dawb thiab pom muaj nyob hauv ntau yam minerals thiab ores. Manganese yog cov cim tseem ceeb rau tib neeg thiab ua lub luag haujlwm tseem ceeb hauv ntau yam txheej txheem lom neeg. Nws yog dav siv nyob rau hauv kev lag luam rau nws cov khoom xws li siab zog, corrosion kuj, thiab muaj peev xwm los tsim alloys.
Ferro manganese, ntawm qhov tod tes, yog ib qho alloy ntawm manganese nrog hlau. Nws yog tsim los ntawm kev txo cov manganese dioxide (MnO2) nrog hlau nyob rau hauv muaj cov pa roj carbon. Ferro manganese feem ntau yog siv los ua deoxidizer thiab desulfurizer hauv kev tsim cov hlau. Nws txhim khu lub zog, hardenability, thiab abrasion tsis kam ntawm steel, ua rau nws haum rau ntau yam kev siv.
Kev sib xyaw:
Lub ntsiab sib txawv ntawm ferro manganese thiab manganese nyob rau hauv lawv cov muaj pes tsawg leeg. Manganese yog ib qho tshuaj dawb huv, whereas ferro manganese yog ib qho hlau uas muaj manganese thiab hlau. Qhov feem pua ntawm cov manganese nyob rau hauv ferro manganese tuaj yeem sib txawv, tab sis nws feem ntau nyob ib ncig ntawm 70-80%. Cov ntsiab lus hlau hauv ferro manganese feem ntau yog nruab nrab ntawm 10-20%.
Lub cev muaj zog:
Manganese yog cov khoom hlau uas muaj qhov kub ntawm 1246 degrees Celsius thiab kub kub ntawm 2061 degrees Celsius. Nws muaj qhov ceev ntawm 7.21 grams ib cubic centimeter thiab yog tus cwj pwm los ntawm nws lub zog tensile siab thiab qis thermal conductivity. Manganese yog paramagnetic, uas txhais tau hais tias nws yog attracted rau magnetic teb tab sis tsis khaws cov hlau nplaum thaum lub teb raug tshem tawm.
Ferro manganese kuj yog cov khoom siv nrog qhov ntom ntom zoo ib yam li cov manganese. Nws lub cev muaj zog yog cuam tshuam los ntawm cov muaj pes tsawg leeg ntawm manganese thiab hlau. Ferro manganese feem ntau yog nkig hauv qhov xwm txheej thiab muaj cov ntsiab lus melting ntau dua piv rau cov manganese ntshiab. Lub xub ntiag ntawm hlau nyob rau hauv lub alloy nce nws hardness thiab toughness.
Daim ntawv thov:
Manganese muaj ntau yam kev siv vim nws cov khoom sib txawv. Nws yog feem ntau siv hauv kev tsim cov hlau tsis muaj steel thiab aluminium alloys. Manganese dioxide, ib tug compound ntawm manganese, yog siv nyob rau hauv qhuav cell roj teeb, pigments, thiab ceramics. Manganese kuj yog ib qho tseem ceeb rau cov nroj tsuag thiab siv los ua chiv hauv kev ua liaj ua teb.
Ferro manganese feem ntau yog siv hauv kev lag luam steel. Nws tau ntxiv rau cov hlau thaum lub sijhawm tsim khoom los txhim kho nws cov khoom. Ferro manganese ua raws li deoxidizer, tshem tawm impurities xws li oxygen thiab sulfur los ntawm cov hlau molten. Nws kuj txhim kho cov hardenability thiab toughness ntawm steel, ua rau nws haum rau kev siv nyob rau hauv kev tsim kho, tsheb, thiab machinery industries.
Kev tsim tawm:
Manganese feem ntau tau txais los ntawm ore pyrolusite (MnO2) los ntawm cov txheej txheem hu ua txo. Cov ore yog thawj zaug crushed thiab roasted los hloov cov manganese dioxide rau hauv daim ntawv ntau soluble. Tom qab ntawd nws yog leached nrog sulfuric acid kom tau txais manganese sulfate tov. Electrolysis yog ua los ntawm kev daws kom tau txais cov hlau ntshiab manganese.
Ferro manganese yog tsim los ntawm cov txheej txheem smelting. Manganese ore yog tov nrog hlau ore thiab coke (carbon) nyob rau hauv ib lub qhov cub. Cov tshuaj tiv thaiv ntawm manganese oxide (MnO2) thiab hlau oxide (Fe2O3) tsim molten ferro manganese. Lub alloy yog ces txias thiab solidified ua ntej ua tiav lawm.
Tus nqi:
Manganese kuj muaj ntau nyob rau hauv lub ntiaj teb crust thiab yog dav muaj. Nws cov nqi feem ntau txiav txim siab los ntawm cov khoom xws li mining thiab refining txheej txheem, nqi zog, thiab kev lag luam xav tau. Tus nqi ntawm manganese tuaj yeem hloov pauv raws li cov xwm txheej no.
Ferro manganese, ntawm qhov tod tes, nyhav ntau dua li cov manganese ntshiab. Cov txheej txheem tsim khoom ntawm ferro manganese suav nrog cov kauj ruam ntxiv thiab yuav tsum tau siv cov khoom siv ntxiv. Tus nqi ntawm ferro manganese yog cuam tshuam los ntawm cov khoom xws li tus nqi ntawm manganese ore, hlau ore, thiab coke, nrog rau cov nqi hluav taws xob cuam tshuam nrog cov txheej txheem smelting.
Xaus:
Hauv cov ntsiab lus, qhov sib txawv tseem ceeb ntawm ferro manganese thiab manganese nyob hauv lawv cov khoom xyaw thiab kev siv. Manganese yog cov tshuaj dawb huv nrog ntau yam kev lag luam thiab kev siv roj ntsha. Ferro manganese, ntawm qhov tod tes, yog ib qho alloy ntawm manganese thiab hlau, feem ntau siv hauv kev lag luam steel. Thaum manganese txhim kho cov khoom ntawm cov hlau, ferro manganese ua raws li deoxidizer thiab desulfurizer, txhim kho cov hlau zoo. Ob leeg manganese thiab ferro manganese ua lub luag haujlwm tseem ceeb hauv cov haujlwm sib txawv thiab pab txhawb rau ntau yam kev lag luam.
