Txoj kev tsim cov ferromolybdenum hmoov nrog cov ntsiab lus siab molybdenum

Kuv pom qhov tsis sib xws: koj cov ntawv qub piav qhia txog cov cuab yeej siv los tsim cov ferromolybdenum hmoov (siv molybdenite, hlau thiab pob sib tsoo), tab sis cov HTML txuas nrog - cov ntaub ntawv nrog cov lus qhia kho (222.html) yog hais txog lub ntsiab lus sib txawv kiag li - kev tsim cov titanium hlau (ferrotitanium) ntawm cov tshuaj tiv thaiv 2 tanium (ferrotitanium).

Txij li cov lus qhia hauv HTML-cov ntaub ntawv (xws li kho cov ntsiab lus "ntse pob zeb" rau "rutile", piav qhia txog kev txo qis ntawm TiO2 los ntawm carbon, silicon thiab aluminium, thiab cov lus ntawm ferrotitanium ntau lawm txoj kev) siv tshwj xeeb rau cov ntawv nyeem ntawm ferrotitanium, Kuv tsis tuaj yeem siv lawv rau koj cov ntawv ntawm ferromolybdenum.

Hloov chaw, kuv tau txhais tag nrho thiab hloov kho qhov hloov tshiab ntawm tsab xov xwm txogferrotitanium cov khoomlos ntawm qhov muab HTML-cov ntaub ntawv, khaws cia cov lus Lavxias thiab qhia tag nrho cov kev hloov kho uas yuav tsum tau ua.

Ferrotitanium ntau lawm: aluminothermic, electrosilicothermic thiab carbonothermic txoj kev

Raw khoom puag

Hauv kev lag luam, ferrotitanium yog tsim los ntawm cov ntaub ntawv raw:titanium{0}}magnetite concentrates (ilmenite, FeTiO₃),rutile (TiO₂)Thiabtitanium khoom(Ti, Ti-V-Al alloys). Cov khoom siv oxide yuav tsum raug txo qis, thaum cov seem tsuas yog yaj. Titanium dioxide (TiO₂) yog ib qho nyuaj oxide los txo, thiab txhua tus neeg txo qis coj txawv txawv - sib txawv - kev nkag siab qhov sib txawv no yog qhov tseem ceeb rau txoj kev.

Chemistry ntawm cov txheej txheem rov qab

• Cov pa roj carbon tsawg:Thaum qhov kub thiab txias, qhov txo qis ntawm TiO₂ los ntawm carbon ua rau kev tsimtitanium carbide (TiC) ntau dua li cov hlau ntshiab titanium. Qhov tshwm sim yog high-carbon ferrotitanium, uas zoo heev txwv nws txoj kev siv.

• Silicon txo:Silicon ib leeg tsis tuaj yeem txo TiO₂, tab sis qhov sib ntxiv ntawm calcium oxide (CaO) raws li cov flux ua rau cov tshuaj tiv thaiv. Hauv qhov no, titanium thiab silicon tsim cov silicides ruaj khov, uas ua rau ferrotitanium nrog cov ntsiab lus siab ntawm silicon.

• Restoration nrog aluminium:Aluminium muaj peev xwm txo tau TiO₂ rau titanium hlau. Txawm li cas los xij, yog tias tus nqi ntawm txhuas nyob rau hauv tus nqi tsawg dua stoichiometric, ib qho loj npaum li cas yog tsimtitanium monoxide (TiO). TiO yog tshuaj lom neeg ruaj khov dua TiO₂ thiab tsis txo los ntawm txhuas; Nws yog ib qho yooj yim oxide uas tsim cov slag nrog Al₂O₃ lossis SiO₂. Txhawm rau daws qhov teeb meem no, CaO - tau ntxiv ob qho tib si los tiv thaiv TiO kom tsis txhob dhau mus rau hauv cov slag thiab kom ntseeg tau tias qhov zoo tshaj plaws ua tiav.

Qhov zoo ntawm ilmenite:Kev txo qis ntawm ilmenite (FeTiO₃) nrog txhuas yog yooj yim dua li kev txo cov ntshiab TiO₂, thiab qhov sib ntxiv ntawm CaO muaj qhov zoo tib yam. Tias yog vim li cas aluminothermic txo ntawm titanium mloog zoo yog lub ntsiab kev lag luam ntau lawm txoj kev - cov khoom ua tau muaj cov ntsiab lus tsis tshua muaj carbon, tab sis cov ntsiab lus nce me ntsis ntawm txhuas thiab silicon.

Plaub txoj kev tsim khoom loj

Cov lus nug nquag nug txog ferromolybdenum hmoov

Yuav ua li cas kom tau txais ferromolybdenum hmoov nrog cov ntsiab lus siab molybdenum?

Ferromolybdenum hmoov yog tau los ntawm crushing thiab sib tsoo cam khwb cia ferromolybdenum los yog hmoov metallurgy. Cov ntsiab lus siab molybdenum yog ua tiav los ntawm kev ua kom zoo ntawm cov ntsiab lus ntawm tus nqi.

ferromolybdenum hmoov siv rau dab tsi?

Ferromolybdenum hmoov yog siv rau cov hlau alloying, tsim cov khoom siv vuam, tsim cov alloys nyuaj thiab ua ib qho ntxiv hauv cov hmoov metallurgy.

Qhov feem ntawm ferromolybdenum hmoov yog qhov xav tau tshaj plaws?

Cov feem nrov tshaj plaws yog 0-1 hli, 1-3 hli thiab 3-5 hli. Cov hmoov zoo yog siv hauv cov hmoov metallurgy, cov feem loj dua - rau alloying steel.

Yuav khaws ferromolybdenum hmoov li cas?

Cov hmoov yuav tsum tau muab cia rau hauv qhov chaw qhuav hauv ntim ntim, tiv thaiv los ntawm ya raws. Kev sib cuag nrog cov dej noo tuaj yeem ua rau oxidation thiab deterioration ntawm cov khoom.

Nws puas tuaj yeem tsim ferromolybdenum hmoov raws li tus neeg yuav tsum tau ua?

Yog lawm, nws muaj peev xwm tsim ferromolybdenum hmoov nrog cov ntsiab lus molybdenum thiab particle loj raws li cov neeg siv khoom tshwj xeeb.

• Aluminothermic ferrotitanium yog cov txheej txheem ntxiv hauv steelmaking: cov ntsiab lus carbon tsawg tiv thaiv cov teeb meem decarburization, thiab qib nruab nrab ntawm Al thiab Si tau txais rau feem ntau ntawm cov hlau.

• Cov khoom uas muaj cov ntsiab lus siab ntawm carbon thiab silicon yog siv qhov twg lawv cov tshuaj muaj pes tsawg leeg tau txais los yog txawm tias yuav tsum tau siv tshuab.

• Cov khib nyiab remelting tso cai rau siv tau zoo tshaj plaws ntawm cov khoom pov tseg titanium alloys thiab yog txoj kev siv hluav taws xob tsawg tshaj plaws.

Cov cheeb tsam ntawm daim ntawv thov

Ferrotitanium ntxiv rau molten steel rau alloy titanium - uas ua rau kom muaj zog, corrosion kuj thiab grain refinement nyob rau hauv cov qauv hlau, stainless hlau thiab tshwj xeeb alloys, thiab kuj yog siv nyob rau hauv lub casting ntawm tej yam cam khwb cia hlau.

Cov lus pom zoo thaum xaj

• Txheeb xyuas Ti cov ntsiab lus, Al / Si / C qib thiab txiav me me (feem ntau 10-50mm lossis 50-100mm pieces) tiv thaiv koj cov lus qhia steel.

• Thov Hoobkas daim ntawv pov thawj zoo nrog tag nrho cov tshuaj ntsuam xyuas (Ti, Al, Si, C, P, S).

• Rau cov qib tseem ceeb ntawm cov hlau, pom zoo rau kev txwv txhuas thiab silicon ua ntej kom tsis txhob muaj teeb meem nrog cov hlau tsis muaj hlau nyob hauv cov hlau.
