Qhov zoo ntawm ferrosilicon nitride hauv cov txheej txheem steelmaking yog raws li hauv qab no

Cov nyhuv deoxidation zoo:

Cov khoom siv silicon hauv ferrosilicon nitride muaj lub peev xwm los khi cov pa oxygen, thiab tuaj yeem hnov mob nrog oxygen hauv cov hlau molten los tsim cov khoom ruaj khov xws li nitrogen, tshem tawm cov pa oxygen los ntawm cov hlau molten, yog li txhim kho cov hlau zoo. Ntxiv mus, piv nrog cov tshuaj deoxidizers ib txwm muaj, nws muaj cov nyhuv deoxidation zoo dua thiab ceev degassing ceev, uas pab txuag lub sij hawm tsim khoom thiab nqi.

Muaj peev xwm nqus tau impurities:

Thaum lub sij hawm steelmaking, ferrosilicon nitride tuaj yeem nqus thiab sib txuas cov impurities hauv cov hlau molten, xws li sulfur, oxygen, carbon, thiab lwm yam. Cov impurities no yuav txo cov purity thiab lub zog ntawm cov hlau. Siv ferrosilicon nitride ua ib qho impurity absorber tuaj yeem txhim kho qhov zoo thiab purity ntawm cov hlau, txo qhov tsim ntawm cov khoom siv, thiab ua kom cov txheej txheem ntawm cov hlau tsis sib xws thiab kev ua haujlwm ruaj khov.

Qhov tseem ceeb alloy ntxiv dag zog rau cov nyhuv:

Thaum lub sij hawm steelmaking txheej txheem, cov hlau atoms nyob rau hauv cov hlau yuav ua ke nrog cov nitrogen atoms nyob rau hauv ferrosilicon nitride los tsim ib tug tshiab alloy theem. Cov txheej txheem alloy no muaj cov khoom siv zoo heev, xws li lub zog siab, siab hardness thiab zoo hnav tsis kam, uas tuaj yeem txhim kho lub zog, hardness thiab hnav tsis kam ntawm steel thiab ua tau raws li qhov yuav tsum tau ua ntawm steel kev ua tau zoo hauv ntau yam engineering.

Stable chemical zog:

Ferrosilicon nitride muaj cov tshuaj muaj zog ruaj khov ntawm qhov kub thiab txias thiab yuav tsis deteriorate los yog yaj nyob rau hauv qhov kub kub ntawm steelmaking. Nws pab kom ruaj khov cov tshuaj tiv thaiv nyob rau hauv cov txheej txheem steelmaking, ntxiv txhim kho qhov zoo thiab kev ua tau zoo ntawm steel, thiab xyuas kom meej qhov kev vam meej ntawm steelmaking ntau lawm.

Grain refinement:

Ferrosilicon nitride tuaj yeem kho lub koom haum cov qauv ntawm cov hlau molten kom tsim cov nplej zoo thiab zoo ib yam, yog li kev txhim kho cov khoom siv ntawm cov hlau molten thiab txhim kho cov tawv thiab ductility ntawm hlau.

Tus nqi txo:

Thaum ua tau siab -lub zog microalloyed steel, microalloying scheme ntawm ferrosilicon nitride ua ke nrog rau lwm yam alloying ntsiab yog saws, xws li FeV50+FeSi₃N₄ microalloying scheme thaum tsim HRB400 steel tuav. Piv nrog rau kev siv ib txwm siv cov ntsiab lus alloying, nws tuaj yeem txo cov nqi alloying, ua tiav cov nqi txo thiab txhim kho kev ua haujlwm, thiab muaj txiaj ntsig zoo rau kev lag luam.

FAQ

Q1: Dab tsi yog qhov zoo ntawm ferrosilicon nitride piv rau ferrosilicon zoo tib yam thiab manganese nitride?

A1:

vs Ferrosilicon: Ferrosilicon nitride muab ob qho tib si silicon thiab nitrogen, ua tiav ob txoj haujlwm ntawm deoxidation thiab microalloying. Ordinary ferrosilicon tuaj yeem tsuas yog deoxidize thiab tsis tuaj yeem muab cov nitrogen zoo.

vs Manganese nitride: Cov khoom silicon nyob rau hauv ferrosilicon nitride nws tus kheej kuj muaj deoxidation thiab ntxiv dag zog rau, tsim ib tug synergistic nyhuv nrog nitrogen. Tsis tas li ntawd, hauv qee qib steel (xws li HRB400), nitrogen ua haujlwm nrog silicon thiab manganese, uas ua rau muaj txiaj ntsig zoo dua ntxiv.

Q2: Puas tuaj yeem siv ferrosilicon nitride los hloov ib feem ntawm ferrovanadium txo nqi?

A2:Yog lawm, qhov no yog qhov tseeb ntawm tus nqi tseem ceeb ntawm ferrosilicon nitride. Ferrovanadium yog kim, thaum lub caij nitrogen hauv ferrosilicon nitride tuaj yeem txhawb nqa VN nag lossis daus, txhim kho kev txhim kho ntxiv ntawm vanadium. Los ntawm kev ntxiv nitrogen rau cov hlau, tus nqi ntawm ferrovanadium ntxiv tuaj yeem txo qis thaum tuav lub zog. Raws li kev lag luam tus nqi sib txawv thiab cov txheej txheem tshwj xeeb, tus nqi hlau alloy ib tuj ntawm cov hlau tuaj yeem raug txo los ntawm 15-30% lossis ntau dua. Peb tuaj yeem muab cov qauv ntsuas tus nqi kom ntxaws rau koj.

Q3: Puas yog nitrogen yield ntawm silicon nitride ferronitride ruaj khov? Yam dab tsi cuam tshuam rau nws?

A3: Cov txiaj ntsig nitrogen feem ntau yog nruab nrab ntawm 60-80%, tab sis nws cuam tshuam los ntawm cov hauv qab no:

Oxygen / sulfur cov ntsiab lus ntawm cov hlau molten: qhov siab dua cov pa oxygen thiab sulfur, qhov qis nitrogen tawm los. Yog li ntawd, cov hlau molten yuav tsum zoo deoxidized ua ntej ntxiv.

Ntxiv txoj kev thiab nplawm: Ntxiv nrog rau cov kwj dej thiab nplawm nrog hauv qab - tshuab argon tuaj yeem txhim kho cov txiaj ntsig zoo.

Cov hlau muaj pes tsawg leeg: Lub xub ntiag ntawm nitride- tsim cov ntsiab lus xws li Cr, V, thiab Nb nyob rau hauv cov hlau ua rau kom cov dej solubility ntawm nitrogen, yog li ua kom cov qoob loo.

Peb pab pawg kws tshaj lij tuaj yeem pab koj txhawm rau txhim kho cov txheej txheem kom tau txais kev ruaj khov thiab siab nitrogen tawm los.
