Dab tsi Electrolytic Manganese Flakes Yog
Electrolytic manganese hlau yog tsim los ntawm electrolysis es tsis yog los ntawm smelting. Manganese ore yog leached rau manganese sulphate tov, purified, thiab pub rau ib tug electrolytic cell uas manganese deposits ntawm lub cathode. Cov deposit yog stripped thiab ua tiav rau hauv flakes, uas yog daim ntawv uas feem ntau buyers paub: nyias, nkig, nyiaj rau grey daim hlau nrog ib tug siab metallic lustre. Vim tias cov hlau tsis dhau los ntawm cov kauj ruam molten smelting, cov txheej txheem nce mus txog qib purity uas smelted ferromanganese tsis tuaj yeem, thiab qhov purity yog vim li cas cov khoom muaj. Cov flakes yog tom qab ntawd siv qhov uas seem carbon, silicon los yog phosphorus los ntawm txoj kev smelting yuav tsis tsim nyog.
Hom Specification ntawm Electrolytic Manganese Flakes
| Element | txwv | Tej yam tshwm sim yog tshaj |
|---|---|---|
| Manganese, Mn | tsis tsawg dua 99.70 feem pua | qis active cov ntsiab lus, siab dua tus nqi ntxiv rau ib lub tshav kub |
| Carbon, C | tsis ntau tshaj 0.04 feem pua | carbon khaws cia hauv qis- carbon steel thiab alloys |
| Sulfur, S | tsis ntau tshaj 0.05 feem pua | sulfur pickup, tsis zoo rau qis- qib sulfur |
| Phosphorus, P | tsis ntau tshaj 0.005 feem pua | embrittlement txaus ntshai nyob rau hauv siab -manganese thiab stainless qib |
| Hlau plus silicon plus selenium | tsis ntau tshaj 0.205 feem pua | residual contamination, cuam tshuam rau kev ntsuas kev huv |
| Daim ntawv thiab ntim | flakes; hnab loj ntawm 1,000 kg net | tuav, dissolution thiab noo noo tswj |
Cov ntsiab lus txwv saum toj no yog cov khoom lag luam xa tawm rau siab purity electrolytic manganese flakes. Qib kev xaiv rau cov hlau manganese, suav nrog 99.7 feem pua chav kawm, tau teeb tsa hauv GB / T 2774, uas tseem qhia txog cov txheej txheem tshuaj xyuas siv los daws qhov kev sib haum xeeb. Qhov txwv phosphorus yog qhov nruj tshaj plaws ntawm cov txheej txheem thiab ib qho kev sib tw feem ntau ntawm kev xa khoom, vim tias nws yog cov khoom uas feem ntau cuam tshuam ncaj qha rau cov khoom ntawm cov hlau kawg los yog alloy.
Vim li cas Flakes thiab Tsis Ingot lossis Briquette
Daim ntawv ua raws li txoj kev melting. Flakes muaj qhov chaw siab tshaj -rau- ntim piv, yog li lawv yaj sai sai thaum ntxiv rau yaj lossis ib lub ladle, uas haum rau induction melting, me me alloy ntxiv thiab cov txheej txheem txuas ntxiv uas yuav tsum tau ceev thiab khaws cov khoom zoo. Ingot thiab briquette yog denser thiab yooj yim rau tsub nqi nyob rau hauv tej, thiab lawv nyiam nyob qhov twg qhov ntxiv yog loj los yog qhov twg tus nqi yuav tsum ciaj sia tuav tsis tau nplua. Flakes kuj nqa ib zaj duab xis oxide nyias los ntawm cov txheej txheem electrolytic; qhov twg cov oxide saum npoo yuav ua rau muaj kev puas tsuaj, qhov kev xyaum ntxiv es tsis yog cov khoom raug hloov kho, piv txwv li los ntawm kev ntxiv hauv qab lub hau los yog ntawm qhov taw tes ntawm kev nplawm zoo.
Daim ntawv thov thoob plaws hlau, txhuas thiab roj teeb
Peb kawg siv dominate xav tau. Hauv steelmaking, manganese yog deoxidiser thiab desulphuriser, thiab nws nce hardenability ntawm qib siv nyob rau hauv siab -manganese thiab stainless qib. Nyob rau hauv aluminium alloys, manganese txhim kho corrosion kuj thiab tswj cov morphology ntawm hlau - cov kabmob theem, thiab ntawm no cov hlau tsis tshua muaj thiab silicon cov ntsiab lus ntawm cov khoom siv electrolytic yog qhov zoo tshaj plaws vim tias cov ntsiab lus nruj nruj hauv cov ntsiab lus txhuas. Hauv kev siv roj teeb thiab tshuaj lom neeg, manganese yog muab los ntawm cov hlau los yog, feem ntau, raws li siab -purity manganese sulphate tau los ntawm tib txoj kev electrolytic; cov hlau kuj tseem siv los tsim cov ntsev manganese thiab siab -purity oxides.
Kev tuav, noo noo thiab xa khoom kuaj xyuas
Electrolytic manganese flakes yog nkig thiab nqus dej ntawm qhov chaw yog tias lawv khaws cia rau hauv qhov chaw ntub dej, thiab qhov chaw oxidation nce ntxiv nrog lub sijhawm thiab rov ua dua qhov kub thiab txias. Yog li ntawd, lub hnab loj yuav tsum tau khaws cia rau hauv qhov chaw qhuav, npog lub khw, tawm hauv av, thiab qhib kom ze li sai tau rau lub sijhawm siv. Kev xa khoom xa tuaj uas ntes tau cov teeb meem feem ntau yog qhov yooj yim: hnyav lub hnab tiv thaiv cov ntaub ntawv tshaj tawm, tshuaj xyuas cov qauv rau kev nplua tsim nyob rau hauv kev thauj mus los, tshuaj xyuas cov xim saum npoo rau hnyav oxidation lossis xeb staining, thiab lees paub cov ntaub ntawv txheeb xyuas rau manganese thiab phosphorus. Kev khaws cov qauv siv kaw cia ntawm txhua qhov ntau tso cai rau cov lus nug tom qab hais txog kev sib xyaw kom haum rau cov khoom siv tiag tiag.
Cov lus nug nquag
Q:Dab tsi yog qhov txawv ntawm electrolytic manganese hlau thiab ferromanganese?
A: Ferromanganese yog tsim los ntawm smelting thiab muaj cov pa roj carbon ntau, silicon thiab hlau. Electrolytic manganese hlau yog tsim los ntawm electrolysis thiab ncav cuag 99.7 feem pua manganese los yog siab dua, uas yuav tsum tau nyob qhov twg cov seem seem yog nruj me ntsis txwv.
Q:Vim li cas phosphorus txwv nruj heev?
A: Phosphorus yog lub ntsiab feem ntau yuav ua rau degrade toughness thiab corrosion cwj pwm nyob rau hauv kawg steel los yog alloy, thiab nws tsis yooj yim muab tshem tawm thaum nws tau nkag mus rau hauv lub yaj. Qhov tsawg phosphorus specification yog li tiv thaiv tag nrho cov txheej txheem qis.
Q:Yuav khaws cov flakes li cas ua ntej siv?
A: Qhuav, npog, tawm hauv av, thiab kom deb ntawm dej los yog condensation. Flakes uas tau absorbed saum npoo av yuav tsum tau qhuav los yog them rau ntawm ib qho kev nplawm zoo kom cov oxide zaj duab xis tsis cuam tshuam nrog kev tawg.
Q:Puas yog flakes haum rau aluminium alloying?
A: Yog, thiab cov ntsiab lus tsis tshua muaj hlau thiab silicon yog qhov zoo dua nyob rau ntawd, vim hais tias cov ntsiab lus tau raug txwv nyob rau hauv feem ntau cov ntsiab lus txhuas. Kev tawg sai ntawm flakes kuj haum rau qhov me me, kev tswj hwm qhov tseeb ntawm kev coj ua ntawm txhuas.
Q:Cov ntsiab lus manganese tau txheeb xyuas li cas ntawm kev xa khoom?
A: Los ntawm kev txheeb xyuas tus neeg sawv cev piv txwv ntawm ntau thiab sib piv cov txiaj ntsig nrog qhov tsawg kawg nkaus tshaj tawm, ua ke nrog carbon, sulfur thiab phosphorus. Ib qho piv txwv ntawm kev sib khi ntawm txhua qhov ntau yog kev coj ua.
Q:Dab tsi yog lub tsheb thauj khoom ib txwm muab?
A: Lub hnab loj ntawm 1,000 kg net rau kev siv ntau, thiab cov pob me me uas qhov sib ntxiv ntawm tus nqi qis lossis qhov twg cov khoom yuav tsum tau hnyav rau hauv cov khoom me me.
