Kusiyana pakati pa Ferro Silicon Nitride ndi Silicon Nitride

Ferrosilicon nitridendimchere wa siliconzimamveka ngati zinthu ziwiri zofanana, koma kwenikweni, ndizosiyana kwambiri. Nkhaniyi ifotokoza kusiyana pakati pa ziwirizi mosiyanasiyana.

Kusiyana kwa Tanthauzo

Ferro siliconndi ferrosilicon nitride ali ndi zolemba zosiyanasiyana ndi katundu.

Kodi Ferrosilicon Nitride ndi chiyani?

Ferrosilicon nitridendi gulu la silicon nitride, chitsulo ndi ferrosilicon. Nthawi zambiri amapangidwa ndi nitridation mwachindunji ferrosilicon aloyi FeSi75 pa kutentha kwambiri. Gawo lalikulu la Si3N4 limawerengera 75% ~ 80%, ndipo gawo lalikulu la Fe limawerengera 12% ~ 17%. Magawo ake akuluakulu ndi α-Si3N4 ndi β-Si3N4, kuphatikizapo Fe3Si ena, α-Fe ndi ochepa kwambiri a SiO2.

Monga mtundu watsopano wa zinthu zopanda oxide refractory,ferrosilicon nitrideali ndi sintering yabwino komanso kukhazikika kwamankhwala, kukana kwambiri, kutsika kwamphamvu kwamafuta ochepa, kukana kugwedezeka kwamafuta, kulimba kwa kutentha kwambiri komanso kusinthasintha kwamafuta, kukana kwa dzimbiri komanso kukana kuvala.

Kodi Ferrosilicon N'chiyani?

Ferrosilicon(FeSi) ndi aloyi wachitsulo ndi silicon, makamaka ntchito zitsulo deoxidation ndi monga alloying chigawo chimodzi. ZhenAn ndi m'modzi mwa otsogola opanga ma aloyi apamwamba kwambiri a ferrosilicon ku China, ndipo ndife okonzeka kukuthandizani kudziwa chomwe chili chabwino kwambiri pakugwiritsa ntchito kwanu.

Gulu laFerro Silicon Nitride

Ferro silicon nitrideali ndi kuuma kwakukulu, malo osungunuka kwambiri komanso kukana kwambiri kuvala. Malinga ndi njira zosiyanasiyana zopangira ndi ma formula, chitsulo cha silicon nitride chikhoza kugawidwa m'mitundu iyi:

Ferro silicon nitride (Si3N4-Fe): Silicon nitride iron imapezeka mwa kusakaniza gwero la silicon, gwero la nayitrogeni (monga ammonia) ndi ufa wachitsulo ndikuchitapo pa kutentha kwambiri. Ferro silicon nitride imakhala ndi kuuma kwakukulu, malo osungunuka kwambiri, kukana kwabwino kwa mavalidwe ndi kukana kwa okosijeni kolimba, ndipo nthawi zambiri amagwiritsidwa ntchito popanga zipangizo zosagwira kutentha kwambiri ndi zida za ceramic.

Ferro silicon nitride alloy (Si3N4-Fe): Silicon nitride iron alloy imapezeka mwa kusakaniza silicon, gwero la nayitrogeni ndi ufa wachitsulo mugawo linalake ndikuchita pa kutentha kwakukulu. Silicon nitride iron alloy imakhala ndi kuuma kwambiri, malo osungunuka kwambiri, kukana kwabwino, kulimba mtima komanso kulimba, ndipo nthawi zambiri amagwiritsidwa ntchito popanga zida zolimba kwambiri zosavala komanso zigawo zamapangidwe.

Kodi Mitundu Ya Ferrosilicon Ndi Chiyani?

Ferrosiliconnthawi zambiri amagawidwa molingana ndi zomwe zili m'zigawo zing'onozing'ono zosiyanasiyana, kutengera zofunikira zomwe zimagwiritsidwa ntchito. Maguluwa akuphatikizapo:

Low carbon ferrosilicon ndi ultra-low carbon ferrosilicon- amagwiritsidwa ntchito kupewa kubweretsanso mpweya popanga zitsulo zosapanga dzimbiri ndi zitsulo zamagetsi.
Low titaniyamu (kuyera kwambiri) ferrosilicon- amagwiritsidwa ntchito kupewa TiN ndi TiC inclusions muzitsulo zamagetsi ndi zitsulo zina zapadera.
Low aluminium ferrosilicon- amagwiritsidwa ntchito kupeŵa mapangidwe olimba a Al2O3 ndi Al2O3-CaO mumagulu osiyanasiyana azitsulo.
Ferrosilicon yapadera- mawu wamba okhudza zinthu zosiyanasiyana zomwe zili ndi ma alloying ena.

Kusiyana kwa Njira Zopangira

Ferrosilicon nitride ndi silicon nitride ali ndi njira zosiyanasiyana zopangira.

Kupanga Njira Kuyenda KwaFerrosilicon nitride

Kupanga kwa ferrosilicon nitride makamaka kumaphatikizapo kusakaniza ufa wa silicon, ufa wachitsulo ndi gwero la carbon kapena gwero la nayitrogeni mu gawo linalake, ndikuyika zinthu zosakanikirana muzitsulo zotentha kwambiri kuti zitheke. Zomwe kutentha kwa ferrosilicon carbide nthawi zambiri kumakhala madigiri 1500-1800 Celsius, ndipo kutentha kwa ferrosilicon nitride nthawi zambiri kumakhala madigiri 1400-1600 Celsius. Zomwe zimapangidwira zimakhazikika kutentha kwa chipinda, ndiyeno pansi ndi sieved kuti mupeze ferrosilicon nitride yomwe mukufuna.

Njira Yopangira Ferrosilicon

FerrosiliconNthawi zambiri amasungunulidwa m'ng'anjo yoyaka ndi miyala, ndiyeno njira yosalekeza imagwiritsidwa ntchito. Kodi njira yopangira ntchito mosalekeza ndi iti? Zimatanthawuza kuti ng'anjoyo imasungunuka mosalekeza pambuyo pa kutentha kwakukulu, ndipo ndalama zatsopano zimawonjezeredwa mosalekeza panthawi yonse ya smelting. Palibe mawonekedwe a arc panthawiyi, kotero kutentha kwa kutentha kumakhala kochepa.

Ferrosilicon imatha kupangidwa mosalekeza ndikusungunuka m'ng'anjo zazikulu, zapakatikati komanso zazing'ono. Mitundu ya ng'anjo ndi yokhazikika komanso yozungulira. Ng'anjo yamagetsi ya rotary yakhala ikugwiritsidwa ntchito kwambiri chaka chino chifukwa kusinthasintha kwa ng'anjo kungathe kuchepetsa kugwiritsidwa ntchito kwa zipangizo ndi magetsi, kuchepetsa mphamvu ya ntchito yokonza ndalama, komanso kupititsa patsogolo ntchito. Pali mitundu iwiri ya ng'anjo zamagetsi zozungulira: gawo limodzi ndi magawo awiri. Ng'anjo zambiri zimakhala zozungulira. Pansi pa ng'anjo ndi pansi pa ng'anjo yogwira ntchito zimamangidwa ndi njerwa za carbon, kumtunda kwa ng'anjo kumamangidwa ndi njerwa zadongo, ndipo ma electrode odzipangira okha amagwiritsidwa ntchito.

Kugwiritsa Ntchito KwaFerrosilicon

Ntchito: Amagwiritsidwa ntchito makamaka mumakampani opanga zitsulo, monga deoxidizer ndi aloyi zowonjezera, amatha kusintha mphamvu, kuuma ndi kukana dzimbiri kwachitsulo.

Kugwiritsa ntchito kwaFerro Silicon Nitride

Ntchito: Zomwe zimagwiritsidwa ntchito popanga zida ndi zida zosagwirizana ndi dzimbiri, monga mipeni, mayendedwe, ndi zina zomwe zimafunikira mphamvu yayikulu komanso kukana kuvala.
