Ferro Silicon Nitride (Fesin) yog ib qho ntau yam ferroalloy ceramic composite uas tus choj sib txuas ntawm tus nqi ntawm cov khoom siv metallurgical thiab refractory. Muaj cov Silicon Nitride (Si₃n₄), Hlau (Fe), thiab cua hlob, ua rau nws muaj kev lag luam siab, ua rau muaj kev lag luam tawm, thiab kev lag luam refract.

Fesi3N4 yog cov hluavtaws sib xyaw ua ke los ntawm qhov siab- kub nitridation ntawmferrosilicon, uas ua rau sib xyaw ntawm silicon nitride (Si₃n₄) thiab hlau -} silicon alloy (fe₃skes. Tsis zoo li cua ntshiab silicon nitride (lub siab- Silicon Nitride rau cov neeg tsim khoom lag luam rau kev pheej yig thiab thev naus laus zis, ua rau zoo rau kev siv.

Tshuaj lom neeg cov tshuaj:

Ib feem	Cov ntsiab lus ntau	Lub luag haujlwm hauv kev ua tau zoo
Nitrogen (n)	10–14%	Txiav txim siab nitride theem cov ntsiab lus; ntau dua n txhim kho deoxidation thiab siab - kub ruaj khov.
Silicon (si)	55–65%	Ua txhaum ua Deagidizer thiab cov ntawv uas muaj hnub qub; Sib tw hlau cov ntsiab lus kom tsis txhob muaj impurities ntau dhau.
Hlau (FE)	20–30%	Txo cov khoom siv nqi thiab txhim kho kev luam ntawv; tswj kom tiv thaiv brittleness.
Carbon (c)	Tsawg dua los yog sib npaug rau 1.0%	Txo kom tsis txhob muaj graphite tsim nyob rau hauv castings, tseem ceeb rau ductile xim zoo.
Aluminium (AL)	Tsawg dua los yog sib npaug rau 1.5%	AIDS Nitridation tab sis txwv kom tiv thaiv kev suav hauv cov hlau.
Phosphorus (p)	Tsawg dua los yog sib npaug rau 0.06%	Tswj kom tsis txhob mob khaub thuas txias hauv cov khoom lag luam hlau.
Sulphur (s)	Tsawg dua los yog sib npaug rau 0.03%	Txo kom tiv thaiv cov kev tawg kub hauv cov cuab yeej thiab Welds.

Qhov Zoo ntawm Ferro Silicon Nitride

Ferro Silicon Nitride sawv tawm hauv kev siv cov ntawv thov vim nws cov txiaj ntsig zoo ntawm cov txiaj ntsig:

Tus nqi - ua tau zoo:5-10x Cov neeg pheej yig dua li cov ntshiab silicon nitride, ua rau nws muaj peev xwm rau bulk siv hauv steelmaking thiab partries.
Ob qho haujlwm ua haujlwm:Ua txhaum ua tus deoxidizer thiab desulfurizer, txo qhov kev xav tau rau ntau yam ntxiv.
Cov txheej txheem sib xyaw:Muaj nyob rau ntau qhov ntau thiab tsawg thiab 0-1mm rau 5-10mm) kom haum cov tshuab pub mis sib txawv (pw, tundish, pwm).
Cov txiaj ntsig ib puag ncig:Cov pa hluav taws av tsawg piv rau cov hmoov nplej zoo; Txo kev cia siab rau ntawm cov av muaj feem tsawg.

Kev thov siab rau ntawm ferrosilicon nitride

Steelmaking: Deagidation & Inclion tswj

Thawj deagidizer:

Ntxiv thaum pw ua hauj lwm (1-3 kg / tuj / tuj / tuj ntawm cov hlau) kom hnov mob oxygen, sib hlub {{3} {}} point silicate (siouss · · AL₂₂₃). Qhov no txo cov oxide tsis xws luag los ntawm 30-40% piv rau cov tsoos ferrosilicon, txhim kho cov hlau toug.

Kev Pab Dovulment Desulation:

Ua haujlwm nrog txiv qaub (cao) kom hloov cov sulphur rau hauv kev ruaj khov, qis -} alirocuildic cov ntaub ntawv hlau thiab cov khoom siv hluav taws xob.

Suav cov sphenoidous:

Transforms ntse, brittle al₂o₃ suav nrog rau hauv kev sib xyaw ua ke, txhim kho cov hlau tus weldability thiab nkees tsis kam los ntawm 15-20%.

Foundry: nodularization & inoculation rau cam khwb cia hlau

Zas Hlau Ntau Lawm:

Raws li tus nqi - aph}} effective effective effective effective effective effective effective effective effective altern. sil iter earth sil (ntxiv rau 0.5-1.0 Qhov no yog dav siv hauv Automotive castings (crankshafts, gearboxes) thiab kev muaj li qub.

Grey Hlau Inoculation:

Txhim kho qhov nucleation graphite, txo "ntawj txias" (brittle dawb hlau tsim) thiab nce tensile lub zog los ntawm 200 MPa rau 250-280 MPa. Qhov zoo tagnrho rau cov yeeb nkab fittings, cov tsev ua twj, thiab cuab cov khoom siv tshuab.

Tus nqi ua nqi kom zoo dua:

30-50% pheej yig dua li lub ntiaj teb tsis tshua muaj txiaj ntsig, ua rau xaiv Nodulizers, ua rau kev xaiv zoo rau nruab nrab- zoo cam khwb cia hlau ntau lawm.

Refractory cov khoom siv: siab - kub ruaj khov

Refract Tribs:

Sib tov nrog alumina (al₂o₃) thiab magnesia (mgo) los tsim nitride-}℃molten hlau thiab hlais kev yaig. Cov cib no nthuav ladle thiab tunish service lub neej los ntawm 20-30% piv rau cov av nplaum tsoos av.
