Musiyano pakati peFerro Silicon Nitride neSilicon Nitride

Ferrosilicon nitrideuyeferro siliconzvinonzwika sezvigadzirwa zviviri zvakafanana, asi kutaura zvazviri, zvakasiyana chaizvo. Chinyorwa chino chichatsanangura musiyano pakati pezviviri kubva kumakona akasiyana.

Tsanangudzo Musiyano

Ferro siliconuye ferrosilicon nitride ine zvinyorwa zvakasiyana uye zvivakwa.

Chii chinonzi Ferrosilicon Nitride?

Ferrosilicon nitridechinhu chinoumbwa nesilicon nitride, iron uye ferrosilicon. Iyo inowanzoitwa neiyo yakananga nitridation yeferrosilicon alloy FeSi75 pakupisa kwakanyanya. Chikamu chikuru cheSi3N4 chinotora 75% ~ 80%, uye chikamu chikuru cheFe chinotora 12% ~ 17%. Zvikamu zvaro zvikuru α-Si3N4 uye β-Si3N4, kuwedzera kune imwe Fe3Si, shoma shoma ye α-Fe uye shoma shoma yeSiO2.

Serudzi rutsva rwe-non-oxide refractory raw material,ferrosilicon nitrideine sintering yakanaka uye kugadzikana kwemakemikari, yakakwirira refractoriness, yakaderera thermal yekuwedzera coefficient, yakanaka yekupisa kutyisa kuramba, kusimba kwekushisa kwepamusoro uye kupisa kwekushisa, kunaka kwekusagadzikana uye kusagadzika kwekupfeka.

Chii chinonzi Ferrosilicon?

Ferrosilicon(FeSi) ialloy yesimbi nesilicon, inonyanya kushandiswa kugadzira simbi deoxidation uye sechinhu chinosanganisa. ZhenAn ndomumwe wevanotungamira vatengesi vemhando yepamusoro ferrosilicon alloys muChina, uye isu takagadzirira kukubatsira kuona chakanakisa chigadzirwa chekushandisa kwako.

Classification OfFerro Silicon Nitride

Ferro silicon nitrideine kuomarara kwepamusoro, kunyungudika kwakakwira uye kwakanakisa kupfeka kuramba. Zvinoenderana neakasiyana maitiro ekugadzira uye mafomula, silicon nitride iron inogona kukamurwa kuita anotevera marudzi:

Ferro silicon nitride (Si3N4-Fe): Silicon nitride iron inowanikwa nekusanganisa silicon sosi, nitrogen sosi (yakadai seammonia) uye upfu hwesimbi uye kuita pakupisa kwakanyanya. Ferro silicon nitride ine kuoma kwepamusoro, nzvimbo yakanyungudika, yakanaka kupfeka kuramba uye yakasimba oxidation kuramba, uye inowanzo shandiswa kugadzira zvinhu zvinodzivirira kupfeka-kupisa uye maturusi eceramic.

Ferro silicon nitride alloy (Si3N4-Fe): Silicon nitride iron alloy inowanikwa nekusanganisa silicon, nitrogen sosi uye iron poda mune imwe chikamu uye kuita pakupisa kwakanyanya. Silicon nitride iron alloy ine kuoma kwakanyanya, kunyungudika kwakakwira, kupfeka kwakanaka kuramba, kusimba kwepamusoro uye kusimba, uye inowanzoshandiswa kugadzira yakakwirira-simba isingapfekere zvinhu uye zvikamu zvechimiro.

Ndedzipi Mhando dzeFerrosilicon?

Ferrosiliconinowanzoiswa maererano nezviri mukati mezvikamu zvidiki zvakasiyana, zvichienderana nezvinodiwa zvekushandisa. Aya mapoka anosanganisira:

Yakaderera kabhoni ferrosilicon uye Ultra-yakaderera kabhoni ferrosilicon- inoshandiswa kudzivirira kudzoserwa kwekabhoni pakugadzira simbi isina tsvina nesimbi yemagetsi.
Yakaderera titanium (yakakwirira kuchena) ferrosilicon- inoshandiswa kudzivirira TiN uye TiC inclusions musimbi yemagetsi uye mamwe masimbi akakosha.
Yakaderera aluminium ferrosilicon- yakashandiswa kudzivirira kuumbwa kweakaoma Al2O3 uye Al2O3-CaO inclusions mumhando dzakasiyana dzesimbi.
Special ferrosilicon-Izwi rakajairwa rinofukidza huwandu hwezvigadzirwa zvakajairwa zvine zvimwe zvinhu zvealloying.

Misiyano Mukugadzira Maitiro

Ferrosilicon nitride uye silicon nitride dzine maitiro akasiyana ekugadzira.

Production Process Flow OfFerrosilicon Nitride

Kugadzirwa kweferrosilicon nitride kunonyanya kusanganisira kusanganisa silicon poda, iron poda uye kabhoni sosi kana nitrogen sosi mune imwe chikamu, uye nekuisa iyo yakasanganiswa zvinhu mune yakakwirira-tembiricha reactor yekukwira-tembiricha kuita. The reaction tembiricha ferrosilicon carbide kazhinji 1500-1800 madhigirii Celsius, uye kuita tembiricha ferrosilicon nitride kazhinji 1400-1600 madhigirii Celsius. Chigadzirwa chacho chinotonhodzwa kusvika kukamuri tembiricha, uye yobva yavhuniwa nekusefa kuti iwane inodiwa ferrosilicon nitride chigadzirwa.

Kugadzira Maitiro eFerrosilicon

Ferrosiliconinowanzonyungudutswa muchoto chinopisirwa ore, uye ipapo nzira yekushanda inoenderera inoshandiswa. Chii chinonzi kuramba kuchiitwa nzira? Zvinoreva kuti choto chinoramba chichinyungudutswa mushure mekupisa kwakanyanya, uye kubhadharisa kutsva kunoramba kuchiwedzerwa panguva yese yekunyungudika. Iko hakuna kuratidzwa kwearc panguva yekuita, saka kurasikirwa kwekupisa kudiki.

Ferrosilicon inogona kuramba ichigadzirwa uye kunyungudutswa mumavira mahombe, epakati uye madiki ari pasi pemvura. Mhando dzevira dzakagadziriswa uye dzinotenderera. Iro rotary electric furnace yakashandiswa zvakanyanya gore rino nekuti kutenderera kwechoto kunogona kuderedza kushandiswa kwezvinhu zvemagetsi nemagetsi, kuderedza kusimba kwekushanda kwekuchaja, uye kuvandudza kugadzirwa kwevashandi. Kune marudzi maviri emagetsi emagetsi anotenderera: single-stage uye double-stage. Mavira mazhinji ane denderedzwa. Pasi pechoto uye chikamu chepasi chekushanda chechoto chinovakwa nekabhoni zvidhinha, chikamu chepamusoro chechoto chinovakwa nezvidhinha zvevhu, uye self-baking electrodes inoshandiswa.

Application OfFerrosilicon

Chikumbiro: Inonyanya kushandiswa muindasitiri yekugadzira simbi, se deoxidizer uye alloy additive, inogona kuvandudza kusimba, kuoma uye kuomarara kuramba kwesimbi.

Kushandiswa kweFerro Silicon Nitride

Chishandiso: Inowanzo shandiswa mukugadzira maturusi asingadzivirire uye asingadziviriri uye zvikamu, zvakaita semapanga, mabhengi, uye mimwe minda inoda simba rakakura uye kusapfeka.
