Nyob rau hauv cov txheej txheem ntawm niaj hnub mellurgical kev lag luam kev nruam kev ua haujlwm ntawm kev tsim khoom zoo thiab muaj txiaj ntsig zoo,Ferro Silicon Nitride HmoovTau dhau los ua cov khoom tseem ceeb los txhawb kev nce qib ntawm cov cuab yeej siv hlau me me nrog nws cov khoom tshwj xeeb, ua si Irreplacable lub luag haujlwm hauv ntau qhov txuas tseem ceeb.
Tus pab cuam muaj zog hauv cov hlau-ua cov txheej txheem ntawm cov tshuab hluav taws kub tawg
Thaum lub tshuab hluav taws xob tawg yog npuaj hlau, kev ua yeeb yam ntawm cov av nplaum tapping yog hais txog kev ua tus npuaj. Silicon Nitride Hmoov yog qhov tseem ceeb ntawm kev tiv thaiv zoo tapping av nplaum. Thaum rhuab, nws hnov mob nrog lwm cov tib yam ntawm kev npuaj teg kom nrawm dua thiab tuaj yeem ruaj khov nyob hauv qhov chaw tsis xis nyob ntawm lub zog cua sov.
Thaum muaj kub, xws li silicon nitride tsim cov theem tshiab, Sic thiab Aln, uas ntxiv dag zog rau Tapping Clay Matrix, thiab cov hlau hais tau koom nrog kev ua kom zoo dua tus qauv. Nyob rau tib lub sijhawm, lub hnub qub tsim los ntawm silicon nitride oxidation oxidation reacts nrog lub neej tapposion, txo cov kev kho lub neej, thiab ua kom cov khoom siv txuas txuas ntxiv ntawm cov tshuab hluav taws xob.
Tsis tas li ntawd, thaum rhuab,Si3N4 HmoovDecomposes n₂ thiab co roj, tsim cov hws nyob hauv cov av nkos thiab txhim kho lub qhov qhib kev ua haujlwm. Tom qab cov hlau tau muab pov thawj, cov av nkos uas muaj ferro silicon nitride yog qhov yooj yim qhib, thiab yolten hlau thiab swb, thiab txo kev pheej hmoo ntawm kev ua haujlwm.
Cov Khoom Zoo Ntxiv rau Kev Tshwj Xeeb Alloy Ntau Lawm
Nyob rau hauv kev tsim cov alloys tshwj xeeb, qhov sib ntxiv ntawm FESI Nitride hmoov tuaj yeem ua kom zoo rau microstructure. Nws cov lus silicon rov qab ua qoob loo, ua kom cov qoob loo sib txawv, ua rau muaj kev sib zog sib luag, thiab txhim kho lub zog thiab tawv ntawm cov alloy; Cov Nitrogen keeb txheej Nitrides, ua lub luag haujlwm hauv kev sib kho zuj zus, txhim kho lub zog thiab kev nyuaj; Cov hlau ntoo kho cov qauv hluav taws xob thiab txhim kho kev ua haujlwm.
Lub alloy hloov los ntawmSilicon Nitride Hmoovtau cuam tshuam ntau yam kev ua tau zoo. Nyob rau hauv cov nqe lus ntawm lub zog, cov tawm los thiab tensile lub zog tau txhim kho, thiab nws tuaj yeem tiv thaiv ntau dua cov nra; Nyob rau hauv cov nqe lus ntawm kev nruj, cov nplej yog kho kom zoo nkauj thiab cov khaub ncaws tsis zoo, kom cov kev cuam tshuam tsis kam thiab nkees ua rau ntawm cov alloy yog txhim kho. Nyob rau tib lub sijhawm, cov hnav tsis kam thiab corrosion tsis kam ntawm alloy kuj tseem txhim kho. Piv txwv li, cov dav hlau cav tau yog ua los ntawm cov alloys muaj silicon nitride hlau hmoov, uas tuaj yeem ua haujlwm ntawm cov pej xeem hlau.
Deagidation thiab Desulfurization tus neeg pab hauv cov txheej txheem statmaking
Thaum ua cov hlau, tshem tawm cov pa oxygen thiab cov neeg tuaj noj mov yog qhov tseem ceeb. Silicon hauv Ferro Silicon Nitride Hmoov yog lub zog deoxidizer muaj zog. Nws reacygen nrog oxygen ntawm qhov kub kom raug muab tshem tawm nyob rau hauv daim ntawv ntawm sluag thiab muaj peev xwm nplua-tune-tune muaj pes tsawg leeg ntawm Molten hlau. Nws cov nitrogen muaj peev xwm kuj tseem tuaj yeem tswj cov qauv Austenite.
Rau desulfurization, calcium (muaj ib qho me me ntawm impurity calcium) hauv SI3N4 hmoov reactse thiab nkag mus rau hauv slag. Ib qho ntxiv, nws hloov lub cev nqaij daim tawv thiab tshuaj lom neeg ntawm cov hlau loj, thiab cov sib xyaw ua ke tuaj yeem txhim kho kev ua tau zoo thiab ua kom zoo dua qub thiab kev ua tau zoo ntawm cov hlau.
Hauv cov kev txuas tseem ceeb ntawm lub zog ua kom tawg yooj yim ntawm cov nyom me me ua kom muaj kev txhawb nqa rau cov qauv siv hluav taws xob thiab kev ua kom zoo dua qub thiab cov khoom siv alloyoy thiab pab deoxidation thiab desulfuration thiab desulfuration. Nrog kev nce qib nruam ntawm kev siv thev naus laus zis, nws cov kev thov yuav ua kom dav.
