Silicon manganese nitride yog ib hom tshiab ntawm cov hlau ntxiv uas muaj kev ua tau zoo thiab kev siv tau zoo piv nrog cov pa nitride alloys. Silicon manganese nitride muaj cov thermal tsis kam, thermal conductivity, tshuaj stability thiab thermal expansion me me. Nws muaj zog micro-alloying thiab nitriding teebmeem yog dav siv nyob rau hauv silicon steel, HRB400 los yog siab tshaj txiv ntseej steel tuav thiab lwm yam teb. Muaj kev ua lag luam zoo heev.
Silicon manganese nitride yog ib qho khoom siv tseem ceeb hauv kev lag luam steel. Nws tuaj yeem muab ntxiv ua deoxidizer thiab alloying ntsiab additive thaum smelting los txhim kho cov hlau zoo, nce hardness, ductility, toughness, hnav tsis kam, thiab lwm yam, thiab txhim kho cov khoom siv ntawm cov hlau. Silicon manganese nitride yog cov khoom tseem ceeb ntawm peb lub tuam txhab. Txhawm rau them rov qab cov kev txhawb nqa ntawm ntau xyoo ntawm cov neeg siv thiab txhawm rau nthuav dav daim ntawv thov ntawm silicon manganese nitride, peb tsuas yog sau thiab qhia txog kev ua haujlwm ntawm silicon manganese nitride.
Qhov loj feem ntawm manganese nyob rau hauv silicon manganese nitride yog 40%-50%. Manganese thiab sulfur tuaj yeem tsim cov ntsiab lus siab melting MnS, uas muaj kev phom sij ntawm cov sulfur rau qee yam. Manganese muaj peev xwm deoxidizing zoo thiab tuaj yeem ua ke nrog FeO hauv cov hlau los ua MnOf thiab nkag mus rau hauv cov slag, yog li txhim kho cov hlau zoo, tshwj xeeb tshaj yog txo cov brittleness ntawm cov hlau thiab nce lub zog thiab hardness ntawm cov hlau. Yog li ntawd, manganese yog ib qho txiaj ntsig zoo hauv cov hlau. Hauv cov khoom siv zoo carbon steel, cov ntsiab lus ntawm manganese yog 0.5%-0.8%, thiab hauv cov qauv hlau nrog cov ntsiab lus siab manganese, nws tuaj yeem ncav cuag 0.7%-1 .2%.
Cov ntsiab lus nitrogen hauv silicon manganese nitride feem ntau yog 12% -32%. Nws yog ib qho tshiab steel-ua alloy additives rau zus tau tej cov high-nitrogen steel, tshwj xeeb alloy hlau, thiab stainless hlau alloy additives. Nitrogen yog sib npaug ntxiv rau cov hlau molten. Thaum lub sij hawm dov txheej txheem, nitrogen yog soj ntsuam nyob rau hauv lub grain ciam teb rau cov tebchaw xws li nitrogen thiab carbon, uas ua lub luag hauj lwm nyob rau hauv refinement, ntxiv dag zog rau lub zog thiab kev daws teeb meem. Nws zoo heev txhim kho lub zog tawm los thiab tensile lub zog ntawm cov hlau thiab ua kom cov yas ntawm cov hlau. Thiab qhov toughness tsis txo qis thaum ua kom ntseeg tau qhov kev ua tau zoo, uas ua lub luag haujlwm tseem ceeb hauv kev ua kom muaj nqi ntxiv-ntxiv steel hom.
