Umehluko phakathi kwe-Ferro Silicon Nitride ne-Silicon Nitride

I-Ferrosilicon nitridefuthii-siliconkuzwakala njengemikhiqizo emibili efana kakhulu, kodwa empeleni, ihluke kakhulu. Lesi sihloko sizochaza umehluko phakathi kwalokhu okubili kusuka ema-engeli ahlukene.

Umehluko Wencazelo

I-silicon ye-Ferrofuthi i-ferrosilicon nitride inezingqikithi nezakhiwo ezahlukene.

Iyini i-Ferrosilicon Nitride?

I-Ferrosilicon nitrideiyinhlanganisela ye-silicon nitride, insimbi ne-ferrosilicon. Ngokuvamile kwenziwa nge-nitridation eqondile ye-ferrosilicon alloy FeSi75 ekushiseni okuphezulu. Ingxenye enkulu ye-Si3N4 ibalwa ku-75% ~ 80%, kanti ingxenye enkulu ye-Fe ibalelwa ku-12% ~ 17%. Izigaba zayo eziyinhloko ziyi-α-Si3N4 kanye ne-β-Si3N4, ngaphezu kwe-Fe3Si ethile, inani elincane le-α-Fe kanye nenani elincane kakhulu le-SiO2.

Njengohlobo olusha lwe-non-oxide refractory raw,i-ferrosilicon nitrideine-sintering enhle kanye nokuzinza kwamakhemikhali, i-refractoriness ephezulu, i-coefficient ephansi yokwandisa ukushisa okushisayo, ukumelana nokushaqeka okuhle kokushisa, amandla okushisa aphezulu kanye ne-conductivity yokushisa, ukumelana nokugqwala okuhle nokumelana nokugqoka.

Iyini i-Ferrosilicon?

I-Ferrosilicon(I-FeSi) iyingxubevange yensimbi ne-silicon, esetshenziselwa ikakhulukazi ukwenza i-steelmaking deoxidation nanjengengxenye ye-alloying. I-ZhenAn ingomunye wabahlinzeki abahamba phambili bezinga eliphezulu le-ferrosilicon alloys e-China, futhi sikulungele ukukusiza unqume umkhiqizo ongcono kakhulu wohlelo lwakho lokusebenza.

Ngokwezigaba

Zombili zinezigaba zazo ezihlukene zomkhiqizo.

Ukuhlukaniswa KweI-Ferro Silicon Nitride

I-Ferro silicon nitrideinobunzima obuphezulu, indawo ephezulu yokuncibilika kanye nokumelana nokugqokwa okuhle kakhulu. Ngokwezinqubo ezahlukene zokukhiqiza namafomula, i-silicon nitride iron ingahlukaniswa ngezinhlobo ezilandelayo:

I-Ferro silicon nitride (Si3N4-Fe): I-silicon nitride iron itholakala ngokuxuba umthombo we-silicon, umthombo we-nitrogen (ofana ne-ammonia) ne-iron powder bese isabela ekushiseni okuphezulu. I-Ferro silicon nitride inobulukhuni obuphezulu, indawo ephezulu yokuncibilika, ukumelana kahle nokugqokwa kanye nokumelana ne-oxidation eqinile, futhi ivame ukusetshenziselwa ukwenza izinto ezikwazi ukumelana nokushisa okuphezulu namathuluzi e-ceramic.

I-Ferro silicon nitride alloy (Si3N4-Fe): I-Silicon nitride iron alloy itholakala ngokuxuba i-silicon, umthombo we-nitrogen ne-iron powder ngesilinganiso esithile futhi isabela ekushiseni okuphezulu. I-Silicon nitride iron alloy inobunzima obuphezulu, indawo encibilika kakhulu, ukumelana okuhle nokugqokwa, amandla aphezulu kanye nokuqina, futhi ivame ukusetshenziselwa ukwenza izinto eziqinile ezingagugi kanye nezingxenye zesakhiwo.

Yiziphi Izinhlobo Ze-Ferrosilicon?

I-Ferrosiliconimvamisa ihlukaniswa ngokuya ngokuqukethwe kwezingxenye ezincane ezahlukahlukene, kuye ngezidingo zohlelo lokusebenza. Lezi zigaba zihlanganisa:

I-carbon ferrosilicon ephansi kanye ne-ultra-low carbon ferrosilicon- esetshenziselwa ukugwema ukufakwa kabusha kwekhabhoni lapho kwenziwa insimbi engagqwali nensimbi kagesi.
I-titanium ephansi (ukuhlanzeka okuphezulu) i-ferrosilicon- esetshenziselwa ukugwema ukufakwa kwe-TiN ne-TiC ensimbi kagesi nakwezinye izinsimbi ezikhethekile.
I-aluminium ephansi ye-ferrosilicon- isetshenziselwa ukugwema ukwakheka kokufakwa okuqinile kwe-Al2O3 kanye ne-Al2O3–CaO kuhlu lwamamaki ensimbi.
I-ferrosilicon ekhethekile- igama elivamile elihlanganisa uhla lwemikhiqizo eyenziwe ngokwezifiso equkethe ezinye izakhi ze-alloying.

Umehluko Ezinqubweni Zokukhiqiza

I-Ferrosilicon nitride ne-silicon nitride zinezinqubo ezihlukene zokukhiqiza.

Ukukhiqizwa Kwenqubo Ukugeleza KweI-Ferrosilicon Nitride

Ukukhiqizwa kwe-ferrosilicon nitride ikakhulukazi kuhilela ukuxuba impushana ye-silicon, impushana yensimbi kanye nomthombo wekhabhoni noma umthombo we-nitrogen ngengxenye ethile, nokubeka izinto ezixubile ku-reactor ephezulu lokushisa ukuze kusabela izinga lokushisa eliphezulu. Izinga lokushisa lokusabela le-ferrosilicon carbide livamise ukuba ngu-1500-1800 degrees Celsius, futhi izinga lokushisa lokusabela le-ferrosilicon nitride ngokuvamile liyi-1400-1600 degrees Celsius. Umkhiqizo wokusabela upholiswa ekamelweni lokushisa, bese uyagaywa futhi uhlungwe ukuze uthole umkhiqizo ofunekayo we-ferrosilicon nitride.

Inqubo Yokukhiqiza Ye-Ferrosilicon

I-Ferrosiliconngokuvamile kuncibilikiswa esithandweni esibaselwa ngensimbi, bese kusetshenziswa indlela yokusebenza eqhubekayo. Ithini indlela yokusebenza eqhubekayo? Kusho ukuthi isithando somlilo sincibilika ngokuqhubekayo ngemva kokushisa okuphezulu, futhi inkokhiso entsha yengezwa ngokuqhubekayo phakathi nayo yonke inqubo yokuncibilika. Akukho ukuchayeka kwe-arc phakathi nenqubo, ngakho-ke ukulahlekelwa ukushisa kuncane uma kuqhathaniswa.

I-Ferrosilicon ingakhiqizwa ngokuqhubekayo futhi incibilikiswe eziko ezinkulu, eziphakathi nezincane ezingaphansi kwamanzi. Izinhlobo zesithando somlilo zilungisiwe futhi ziyajikeleza. Isithando somlilo esijikelezayo sisetshenziswe kabanzi kulo nyaka ngoba ukujikeleza kwesithando somlilo kunganciphisa ukusetshenziswa kwezinto ezingavuthiwe kanye nogesi, kunciphise amandla okusebenza okukhokhiswa kokucubungula, futhi kuthuthukise ukukhiqizwa kwabasebenzi. Kunezinhlobo ezimbili zezithando zomlilo zikagesi ezijikelezayo: isigaba esisodwa kanye nesiteji esiphindwe kabili. Amaziko amaningi ayisiyingi. Ngaphansi kwesithando somlilo kanye nesendlalelo esingaphansi esisebenzayo sesithando somlilo sakhiwe ngezitini zekhabhoni, ingxenye engenhla yesithando somlilo yakhiwe ngezitini zobumba, futhi kusetshenziswa ama-electrode okugcoba.

Izinkambu zohlelo lokusebenza ezahlukene

Mayelana nesicelo, lezi ezimbili nazo zihluke kakhulu.

Isicelo OfI-Ferrosilicon

Isicelo: Ikakhulukazi esetshenziswa embonini yokukhiqiza insimbi, njenge-deoxidizer ne-alloy additive, ingathuthukisa amandla, ubulukhuni nokumelana nokugqwala kwensimbi.

Isicelo seI-Ferro Silicon Nitride

Isicelo: Isetshenziswa kakhulu ekwenzeni amathuluzi nezingxenye ezingagugi futhi zimelana nokugqwala, njengemimese, ama-bearings, nezinye izinkambu ezidinga amandla aphezulu nokumelana nokuguga.
