Ferro Silicon Magnesium Rau Cov Hlau Hlau

Ferro Silicon Magnesium (FeSiMg) alloy yog cov hlau zoo uas muaj hlau (Fe), silicon (Si), magnesium (Mg), thiab lwm yam. FeSiMg alloy plays lub luag haujlwm tseem ceeb hauv cov txheej txheem hlau hlau los ntawm kev muab cov khoom nodularizing, desulfurizing, thiab deoxidizing zog.

Peb muab qhov yooj yim los kho qhov muaj pes tsawg leeg ntawm FeSiMg alloy raws li cov neeg siv khoom tshwj xeeb. Cov ntsiab lus magnesium thiab silicon tuaj yeem hloov kho kom ua tiav cov khoom xav tau thiab ua tau raws li cov kev xav tau tshwj xeeb ntawm cov khoom siv hlau.

Magnesium (Mg): 4-6 feem pua

Silicon (Si): 40-45 feem pua

Hlau (Fe): tshuav nyiaj li cas

Aluminium (Al): Tsawg dua lossis sib npaug li 1.5 feem pua

Calcium (Ca): Tsawg dua lossis sib npaug rau 1.0 feem pua

Rare Earth Elements (RE): Tsawg dua lossis sib npaug rau 1.0 feem pua

Cov pa roj carbon (C): Tsawg dua lossis sib npaug rau 0.15 feem pua

Sulfur (S): Tsawg dua lossis sib npaug rau 0.02 feem pua

Phosphorus (P): Tsawg dua lossis sib npaug rau 0.04 feem pua

Ferro Silicon Magnesium alloy yog ib qho tseem ceeb hauv kev tsim cov hlau ductile. Nws txhawb kev tsim cov graphite nodules, txhim kho ductility, thiab muab cov chaw nucleation rau graphite tsim. Nws kuj pab tswj cov qib sulfur thiab oxygen hauv cov hlau thiab tso cai rau magnesium rov qab.

Spheroidization ntawm Graphite: FeSiMg alloy yog siv nyob rau hauv zus tau tej cov cam khwb cia hlau nrog spheroidal graphite (SG) los yog nodular graphite. Cov alloy txhawb cov spheroidization ntawm graphite flakes, txhim kho cov khoom siv ntawm cov hlau cam khwb cia, xws li lub zog, ductility, thiab kev cuam tshuam. Qhov no ua rau nws tsim nyog rau cov ntawv thov uas yuav tsum muaj kev ua haujlwm siab, xws li cov khoom siv tsheb, cov kav dej, thiab cov khoom siv tshuab.

Kev lag luam Foundry: FeSiMg alloy yog dav siv hauv kev lag luam foundry ua ib qho inoculant thiab nodularizer. Nws yog ntxiv rau cov hlau molten, xws li grey hlau los yog hlau ductile, los txhim kho cov qauv graphite thiab txhim kho cov casting zoo. Cov alloy pab tiv thaiv kev tsim ntawm cov ntawv tsis xav tau graphite, xws li flake graphite, thiab txhawb kev tsim ntawm nodular graphite, ua kom zoo dua machinability thiab txhua yam khoom hauv castings.

Steelmaking: FeSiMg alloy yog qee zaum siv hauv cov txheej txheem steelmaking ua tus neeg sawv cev alloying. Qhov sib ntxiv ntawm FeSiMg tuaj yeem muab cov txiaj ntsig zoo xws li deoxidation, desulfurization, thiab kev hloov pauv ntawm kev suav nrog hauv cov hlau. Nws pab txhim kho cov hlau huv, cov khoom siv kho tshuab, thiab castability. Cov alloy feem ntau yog siv los tsim cov hlau tshwj xeeb, suav nrog cov hlau tsis tshua muaj hlau, cov hlau tsis muaj steel, thiab cov hlau muaj zog.

Vuam Consumables: FeSiMg alloy tseem ua haujlwm hauv kev tsim cov khoom siv vuam, xws li vuam electrodes thiab xov hlau. Lub alloy muaj pes tsawg leeg pab nyob rau hauv deoxidation thiab desulfurization thaum lub sij hawm vuam, txo qhov kev pheej hmoo ntawm kev tsis xws luag nyob rau hauv lub vuam sib koom tes. Nws kuj pab txhawb rau cov khoom siv kho tshuab thiab kev ruaj ntseg ntawm cov hlau vuam.

Magnesium rov qab: FeSiMg alloy muaj cov txheej txheem rov qab los yog rov ua dua magnesium hauv ntau cov txheej txheem hlau ntau lawm. Cov ntsiab lus magnesium hauv cov hlau tuaj yeem muab rho tawm lossis rov siv dua tom qab nws daim ntawv thov, txo cov khoom pov tseg thiab txo cov nqi tsim khoom.
