ZhenAn yog ib qho ntawm cov khoom lag luam zoo ferrosilicon alloys hauv Suav teb, thiab peb npaj los pab koj txiav txim siab cov khoom zoo tshaj plaws rau koj daim ntawv thov.

Nyob rau hauv cov nqe lus ntawm kev faib

Ob leeg muaj lawv tus kheej cov khoom sib txawv.

Classification NtawmFerro Silicon Nitride

Ferro silicon nitridemuaj siab hardness, siab melting point thiab zoo heev hnav tsis kam. Raws li cov txheej txheem ntau lawm thiab cov qauv, silicon nitride hlau tuaj yeem muab faib ua hom hauv qab no:

Ferro silicon nitride (Si3N4-Fe): Silicon nitride hlau yog tau los ntawm kev sib xyaw ntawm silicon qhov chaw, nitrogen qhov chaw (xws li ammonia) thiab hlau hmoov thiab reacting ntawm kub. Ferro silicon nitride muaj siab hardness, siab melting point, zoo hnav tsis kam thiab muaj zog oxidation tsis kam, thiab feem ntau yog siv los tsim high-temperature hnav-resistant cov ntaub ntawv thiab cov cuab yeej ceramic.

Ferro silicon nitride alloy (Si3N4-Fe): Silicon nitride hlau alloy yog tau los ntawm kev sib xyaw silicon, nitrogen qhov chaw thiab hlau hmoov nyob rau hauv ib qho kev faib ua feem thiab reacting ntawm kub. Silicon nitride hlau alloy muaj siab hardness, siab melting point, zoo hnav tsis kam, siab zog thiab toughness, thiab feem ntau yog siv los tsim high-strength hnav-resistant cov ntaub ntawv thiab cov yam ntxwv qhov chaw.

Dab tsi yog Hom Ferrosilicon?

Ferrosiliconfeem ntau yog cais raws li cov ntsiab lus ntawm ntau yam me me, nyob ntawm seb cov ntawv thov yuav tsum tau ua. Cov pawg no suav nrog:

Tsawg carbon ferrosilicon thiab ultra-low carbon ferrosilicon- siv kom tsis txhob rov ua dua cov pa roj carbon thaum ua cov hlau tsis muaj steel thiab hluav taws xob hlau.
Tsawg titanium (siab purity) ferrosilicon- siv los zam TiN thiab TiC suav nrog hauv cov hlau hluav taws xob thiab qee cov hlau tshwj xeeb.
Tsawg aluminium ferrosilicon- siv los zam kev tsim cov tawv Al2O3 thiab Al2O3-CaO suav nrog hauv ntau qib steel.
Tshwj xeeb ferrosilicon- ib lo lus dav dav npog ntau yam ntawm cov khoom lag luam customized uas muaj lwm cov ntsiab lus alloying.

Qhov txawv ntawm cov txheej txheem ntau lawm

Ferrosilicon nitride thiab silicon nitride muaj cov txheej txheem ntau lawm.

Cov txheej txheem ntau lawm ntawmFerrosilicon Nitride

Kev tsim cov ferrosilicon nitride feem ntau suav nrog kev sib xyaw cov hmoov silicon, hlau hmoov thiab cov pa roj carbon lossis nitrogen qhov chaw nyob rau hauv ib qho kev faib ua feem, thiab muab cov khoom sib xyaw rau hauv qhov kub-kub reactor rau cov tshuaj tiv thaiv kub. Cov tshuaj tiv thaiv kub ntawm ferrosilicon carbide feem ntau yog 1500-1800 degrees Celsius, thiab cov tshuaj tiv thaiv kub ntawm ferrosilicon nitride feem ntau yog 1400-1600 degrees Celsius. Cov khoom siv tshuaj tiv thaiv yog txias rau chav sov, thiab tom qab ntawd hauv av thiab sieved kom tau txais cov khoom ferrosilicon nitride uas xav tau.

Cov txheej txheem ntau lawm ntawm Ferrosilicon

Ferrosiliconyog feem ntau smelted nyob rau hauv ib tug ore-hluav taws xob rauv, thiab ces siv ib tug nruam txoj kev ua hauj lwm. Txoj kev ua haujlwm tas mus li yog dab tsi? Nws txhais tau hais tias lub cub tawg tsis tu ncua tom qab qhov kub thiab txias, thiab tus nqi tshiab txuas ntxiv ntxiv thaum lub sij hawm tag nrho cov txheej txheem smelting. Tsis muaj arc raug thaum lub sij hawm tus txheej txheem, yog li ntawd lub tshav kub poob yog kuj me me.

Ferrosilicon tuaj yeem ua tsis tu ncua thiab smelted nyob rau hauv loj, nruab nrab thiab me submersible furnaces. Cov hom rauv yog tsau thiab rotary. Lub tshuab hluav taws xob tig tau siv dav rau xyoo no vim tias kev sib hloov ntawm lub cub tawg tuaj yeem txo cov khoom siv raw thiab hluav taws xob, txo cov kev siv zog ntawm kev ua haujlwm, thiab txhim kho kev ua haujlwm ntawm cov khoom siv. Muaj ob hom rotary hluav taws xob rauv: ib-theem thiab ob-theem. Feem ntau lub cub tawg yog ncig. Hauv qab ntawm lub cub tawg thiab cov txheej txheem ua haujlwm qis ntawm lub cub tawg yog tsim los ntawm cov pa roj carbon cib, lub qhov cub sab saud yog ua los ntawm cov av nplaum cib, thiab nws tus kheej ci electrodes yog siv.

Txawv daim ntawv thov teb

Hais txog kev siv, ob qho tib si kuj txawv heev.

Daim ntawv thov ntawmFerrosilicon

Daim ntawv thov: Feem ntau yog siv rau hauv kev lag luam steel, raws li deoxidizer thiab alloy additive, nws tuaj yeem txhim kho lub zog, hardness thiab corrosion kuj ntawm hlau.

Daim ntawv thov ntawmFerro Silicon Nitride

Daim Ntawv Thov: Feem ntau siv rau hauv kev tsim cov cuab yeej hnav-tiv taus thiab corrosion-resistant thiab qhov chaw, xws li riam, bearings, thiab lwm yam uas yuav tsum tau muaj zog thiab hnav tsis kam.
