Ferrosilicon nitridekwayei-siliconzivakala njengeemveliso ezimbini ezifanayo, kodwa eneneni, zahluke kakhulu. Eli nqaku liza kuchaza umahluko phakathi kwezi zimbini kwii-engile ezahlukeneyo.

Umahluko kwingcaciso

I-silicon ye-Ferrokunye ne-ferrosilicon nitride inokwakheka kunye neempawu ezahlukeneyo.

Yintoni iFerrosilicon Nitride?

Ferrosilicon nitrideyimathiriyeli edibeneyo ye-silicon nitride, intsimbi kunye ne-ferrosilicon. Ngokuqhelekileyo yenziwa nge-nitridation ngqo ye-ferrosilicon alloy FeSi75 kwiqondo lokushisa eliphezulu. I-fraction mass ye-Si3N4 i-akhawunti ye-75% ~ 80%, kunye neqhekeza elikhulu le-Fe libalelwa kwi-12% ~ 17%. Izigaba zayo eziphambili ziyi-α-Si3N4 kunye ne-β-Si3N4, ngaphezu kwe-Fe3Si ethile, inani elincinci le-α-Fe kunye nexabiso elincinci le-SiO2.

Njengodidi olutsha lwe-non-oxide refractory ekrwada,ferrosilicon nitrideine-sintering elungileyo kunye nokuzinza kweekhemikhali, i-refractoriness ephezulu, i-coefficient yokwandisa i-thermal ephantsi, ukuxhathisa ukothuka kwe-thermal, amandla obushushu obuphezulu kunye ne-thermal conductivity, ukuxhathisa okulungileyo kwe-corrosion kunye nokumelana nokunxiba.

Yintoni iFerrosilicon?

Ferrosilicon(i-FeSi) yi-alloy yentsimbi kunye ne-silicon, esetyenziselwa ngokukodwa ukwenza i-steelmaking deoxidation kunye ne-alloying component. I-ZhenAn ngomnye wababoneleli abaphambili bomgangatho ophezulu we-ferrosilicon alloys eTshayina, kwaye sikulungele ukukunceda ubone eyona mveliso ilungileyo yesicelo sakho.

Ngokubhekiselele kuhlelo

Ezi zimbini zineentlobo zazo ezahlukeneyo zemveliso.

Ulwahlulo lweFerro Silicon Nitride

Ferro silicon nitrideinobunzima obuphezulu, indawo ephezulu yokunyibilika kunye nokumelana okugqwesileyo kokunxiba. Ngokweenkqubo ezahlukeneyo zemveliso kunye neefomyula, i-silicon nitride iron inokwahlulwa ibe zezi ntlobo zilandelayo:

I-Ferro silicon nitride (Si3N4-Fe): Intsimbi ye-silicon nitride ifunyenwe ngokuxuba umthombo we-silicon, umthombo we-nitrogen (ofana ne-ammonia) kunye nomgubo wentsimbi kunye nokusabela kwiqondo lokushisa eliphezulu. I-Ferro silicon nitride inobulukhuni obuphezulu, indawo yokunyibilika ephezulu, ukuxhathisa okufanelekileyo kunye nokumelana ne-oxidation eyomeleleyo, kwaye ihlala isetyenziselwa ukwenza izinto ezikwazi ukumelana nobushushu obuphezulu kunye nezixhobo ze-ceramic.

I-Ferro silicon nitride alloy (Si3N4-Fe): I-Silicon nitride iron alloy ifunyenwe ngokuxuba i-silicon, umthombo we-nitrogen kunye ne-iron powder kwinqanaba elithile kwaye iphendule kwiqondo lokushisa eliphezulu. I-Silicon nitride iron alloy inobunzima obuphezulu, indawo ephezulu yokunyibilika, ukuxhathisa okulungileyo, ukomelela okuphezulu kunye nokuqina, kwaye ihlala isetyenziselwa ukuvelisa izinto ezinqabileyo zokunxiba kunye neendawo zesakhiwo.

Ziziphi iintlobo zeFerrosilicon?

Ferrosiliconidla ngokuhlelwa ngokomxholo wamacandelo amancinci ahlukeneyo, ngokuxhomekeke kwiimfuno zesicelo. Ezi ndidi ziquka:

I-carbon ferrosilicon ephantsi kunye ne-ultra-low carbon ferrosilicon- esetyenziselwa ukuphepha ukubuyisela i-carbon xa usenza insimbi engenasici kunye nentsimbi yombane.
I-titanium ephantsi (ucoceko oluphezulu) i-ferrosilicon- esetyenziselwa ukuphepha i-TiN kunye ne-TiC inclusions kwintsimbi yombane kunye nezinye iintsimbi ezikhethekileyo.
I-aluminium ephantsi ye-ferrosilicon- esetyenziselwa ukuphepha ukubunjwa kwe-Al2O3 enzima kunye ne-Al2O3-CaO inclusions kuluhlu lwamabakala ensimbi.
I-ferrosilicon ekhethekileyo-Igama eliqhelekileyo eliquka uluhlu lweemveliso ezilungelelanisiweyo eziqulethe ezinye izinto zokudibanisa.

Umahluko kwiiNkqubo zeMveliso

I-Ferrosilicon nitride kunye ne-silicon nitride zineenkqubo ezahlukeneyo zokuvelisa.

Inkqubo yeMveliso Flow OfFerrosilicon Nitride

Ukuveliswa kwe-ferrosilicon nitride kubandakanya ukuxuba i-silicon powder, umgubo wesinyithi kunye nomthombo wekhabhoni okanye umthombo we-nitrogen kumlinganiselo othile, kunye nokubeka izinto ezixubileyo kwi-reactor yobushushu obuphezulu bokusabela kobushushu obuphezulu. Ubushushu bokusabela kwe-ferrosilicon carbide ngokuqhelekileyo yi-1500-1800 degrees Celsius, kunye nobushushu bokusabela kwe-ferrosilicon nitride ngokuqhelekileyo yi-1400-1600 degrees Celsius. Imveliso yokusabela ipholiswe kwiqondo lobushushu begumbi, kwaye emva koko igalelwe kwaye ihluzwe ukufumana imveliso efunwayo ye-ferrosilicon nitride.

Inkqubo yeMveliso yeFerrosilicon

Ferrosiliconlunyibilikiswa ngokubanzi kwiziko elibaswe ngentsimbi ekrwada, kuze emva koko kusetyenziswe indlela yokusebenza eqhubekayo. Yintoni indlela yokusebenza ngokuqhubekayo? Kuthetha ukuba isithando somlilo siyancibilika ngokuqhubekayo emva kobushushu obuphezulu, kwaye intlawulo entsha yongezwa ngokuqhubekayo ngexesha lenkqubo yonke yokunyibilikisa. Akukho kuvezwa kwe-arc ngexesha lenkqubo, ngoko ke ukulahleka kobushushu kuncinci.

I-Ferrosilicon inokuveliswa ngokuqhubekayo kwaye inyibilikiswe kwiziko elikhulu, eliphakathi kunye nelincinci elingaphantsi kwamanzi. Iintlobo zesithando somlilo zilungisiwe kwaye zijikeleza. Isithando sombane esijikelezayo sisetyenziswe ngokubanzi kulo nyaka ngenxa yokuba ukujikeleza kwesithando somlilo kunokunciphisa ukusetyenziswa kwezinto eziluhlaza kunye nombane, ukunciphisa ubunzima bokusebenza kwentlawulo yokucubungula, kunye nokuphucula imveliso yabasebenzi. Kukho iintlobo ezimbini zeefurnaces zombane ezijikelezayo: inqanaba elinye kunye nenqanaba eliphindwe kabini. Uninzi lweziko zisetyhula. Umphantsi wesithando somlilo kunye nomgangatho ophantsi wokusebenza wesithando somlilo wakhiwe ngezitena zekhabhoni, inxalenye ephezulu yesithando somlilo yakhiwe ngezitena zodongwe, kwaye i-electrodes yokubhaka isetyenziselwa.
