Ferro Silicon Nitrideyog ib qho alloy nrog silicon, hlau thiab nitrogen raws li lub ntsiab lus tseem ceeb. Nws yog mas tsimSilicon Nitride (Si3 N4)Thiab hlau, thiab nws cov tsos feem ntau yog cov nyiaj-grey lossis grey-dub los yog granular, nrog qee yam metallic luster. Ntxiv nrog rau lub ntsiab silicon loj, hlau thiab nitrogen ntsiab, nws cov tshuaj lom neeg muaj kab mob kuj tseem muaj ib qho me me ntawm cov neeg tawg hlab dej xws li carbon, oxygen, thiab txhuas. Cov ntsiab lus tshwj xeeb yuav sib txawv raws li cov txheej txheem ntau lawm thiab cov khoom lag luam tshwj xeeb.
Los ntawm cov txheej txheem ntau lawm pom, muaj feem ntau ob txoj hauv kev los npaj Ferro Silicon Nitride.
Ib qho yog qhov chawferrosilicon hmoovNyob rau hauv ib puag ncig nitrogen thiab nqa tawm cov tshuaj uas nitriding ntawm ib qho kub ntawm 1100 degree -1400 degree. Hauv cov txheej txheem no, nws yog ib qho tseem ceeb heev rau kev tswj kom raug xws li tus nqi kub, sijhawm thiab nitrogen txaus. Only in this way can ferrosilicon and nitrogen react fully to produce high-quality ferro silicon nitride.
Lwm txoj kev yog sib xyawferrosilicon, silicon hmoov, hlau hmoov thiab lwm cov khoom siv raw hauv ib qho kev sib tw, thiab cov hluav taws xob rau hauv lub cub tawg xws li cov cua sov tsis muaj zog lossis cov kev tiv thaiv nitrogen. Qhov no yuav tsum ua kom nruj kev ua kom nruj ntawm cov khoom siv dawb thiab qhov loj ntawm cov khoom siv raw kom ntseeg tau tias cov khoom lag luam zoo.
Hauv kev lag luam metallurgical, daim ntawv thov ntawm ferrosilicon nitride yog heev heev thiab tseem ceeb.
Hauv cov txheej txheem hlau smelting
Nws yog cov txiaj ntsig nitrogen alloying tus neeg sawv cev. Tom qab ntxiv nitrogen rau hlau, nplua thiab dispersed nitride txhawb nqa cov kauj ruam, uas ua rau muaj zog ua kom muaj zog thiab kev qaug zog tiv thaiv cov hlau. Piv txwv li, hauv kev tsim cov hlau tshwj xeeb xws li cov hlau hluav taws xob muaj zog ntau ntxiv, cov qauv hluav taws xob ua kom tau zoo rau cov hlua hlau ua haujlwm rau cov qauv hlau hauv ntau daim teb.
Hauv kev lag luam casting
Ferrosilicon nitride tuaj yeem ua raws li ib tuginoculantthiabtej tawgTxhawm rau txhawb nqa graphitization, tshuaj ntsuab graphitization nplej, txo qhov tsis xws luag thiab kev ua tau zoo ntawm cov chaw castings, thiab txhim kho qhov ua tau zoo thiab tsim nyog ntawm cov cuab yeej.
Piv nrog lwm cov ntaub ntawv, ferrosilicon nitride muaj qhov zoo. Nws tuaj yeem ua tau nitrogen cia li ua tau zoo dua, muaj qhov siab nitrogen kev nqus tus nqi, thiab tuaj yeem tswj cov ntsiab lus nitrogen hauv cov hlau. Los ntawm kev ntxiv nws, kev ua tau zoo ntawm cov hlau tuaj yeem txhim kho, tshwj xeeb yog kev txhim kho ntawm lub zog thiab tawv. Ntxiv mus, nws cov txheej txheem tsim khoom thiab siv tau zoo ib puag ncig thiab tsis ncaj ncees ua kom muaj zog txuag, uas ua tau zoo ntawm kev tsim kho niaj hnub.
