Thaum koom ua ke rau hauv cov tshuab refractory, FeSiN tsim txhawb Si₃N₄ tes hauj lwm uas:

faib cov thermal stress ntau sib npaug

txo cov ntsiab lus tawg pib

txhim kho kev sib txuas ruaj khov ntawm cov khoom

txhim kho cov txheej txheem yooj thaum lub sij hawm expansion thiab contraction cycles

Qhov no mechanism yog tshwj xeeb tshaj yog zoo nyob rau hauvFeSiN rau Al2O3-SiC-C refractorysystems uas thermal cycling tsis kam yog qhov tseem ceeb.

Piv nrog rau cov pa additives, FeSiN muaj qhov ruaj khov microstructural reinforcement nyhuv nyob rau hauv rov qab kub hloov pauv.

⑤ Yuav ua li cas nitrogen txhim kho thermal stability hauv cov ntaub ntawv refractory?

Nitrogen pab txhawb rau refractory kev ua tau zoo los ntawm kev ua kom muaj thermally ruaj khov silicon nitride theem.

Cov theem no muaj:

Tsawg thermal expansion mismatch

siab tsis kam mus tawg propagation

muaj zog sib txuas muaj peev xwm ntawm qhov kub siab

zoo heev tiv thaiv thermal qaug zog

Hauvsiab nitrogen ferrosilicon nitride, nitride network ua denser thiab ruaj khov, txhim khu kev tiv thaiv thermal poob siab thiab cov txheej txheem degradation.

Qhov no yog ib qho laj thawj vim li cas Japanese refractory tuam txhab lag luam tseem ceeb tshaj plaws tswj cov ntsiab lus nitrogen thiab ruaj khov FeSiN zoo.

⑥ Vim li cas FeSiN thiaj li txo qis thiab tawg tawm?

Spalling tshwm sim thaum thermal kev nyuaj siab tshaj qhov kev kam rau ua ntawm cov txheej txheem refractory linings, ua rau cov txheej saum npoo detach.

FeSiN txo spalling los ntawm:

reinforcing grain ciam zog

txhim kho matrix toughness

txo qhov chaw thermal stress concentration

stabilizing internal theem faib

Hauvferrosilicon nitride rau kub hlau khiavthiab cov ntaub ntawv siv hluav taws xob, qhov no ua rau kev loj hlob qeeb qeeb thiab ruaj khov ntev dua - lub sijhawm ua haujlwm.

⑦ Vim li cas Japanese refractory manufacturers tseem ceeb tshaj FeSiN hmoov zoo?

Nyiv cov txheej txheem kev yuav khoom hais txog kev sib xws, kev ua tau zoo, thiab kev ntseeg tau ntawm kev ua haujlwm. Vim li ntawd,ferrosilicon nitride hmoov manufacturersCov ntaub ntawv raug soj ntsuam tsis yog ntawm cov tshuaj muaj pes tsawg leeg, tab sis kuj tseem nyob ntawm:

particle loj sib xws
