Ferro silicon magnesium alloy (FeSiMg)yog cov khoom siv tseem ceeb hauv kev lag luam metallurgical thiab casting. Raws li ib tug tseem ceeb spheroidizing tus neeg saib xyuas thiab alloying additive, nws plays ib tug irreplaceable lub luag hauj lwm nyob rau hauv cam khwb cia hlau spheroidization thiab steel kev ua tau zoo optimization vim lub spheroidizing nyhuv ntawm magnesium thiab lub zog ntawm cov khoom.ferrosilicon. Nws muaj pes tsawg leeg (Mg 4% -10%, Si 40% -55%, Fe tshuav nyiaj li cas) ncaj qha txiav txim siab nws daim ntawv thov cov nyhuv.
Cov ntsiab lus tseem ceeb:Cov qib tseem ceeb FeSiMg8Re2 (Mg 7% -9%, Si 42% -48%, Re 1% -3%, Fe tshuav), FeSiMg6 (Mg 5% -7%, Si 45% -50%, Fe tshuav), impurities Al Tsawg dua lossis sib npaug li 1.0%, S Less dua lossis sib npaug li 0% 0.
Lub cev muaj zog:Melting point 1150-1250 degree, ceev 2.9-3.3g/cm³, silver-grey block (5-30mm) los yog granular (1-10mm) daim ntawv. Magnesium yog yooj yim volatilized ntawm qhov kub thiab txias, yuav tsum tau ceev cov tshuaj tiv thaiv kom ua tiav spheroidization;
Core zoo:Cov nyhuv spheroidization ruaj khov, muaj ob qho tib si spheroidization thiab alloying zog, spheroidization tus nqi tuaj yeem ncav cuag ntau dua 90%, thaum tib lub sijhawm txhim kho cov khoom siv zog thiab tawv, haum rau loj - nplai casting ntau lawm;
Daim ntawv thiab ntim:Thaiv (5-30mm), granular (1-10mm), ntim rau hauv lub hnab ntim dej noo (1000kg / kg / hnub). Ntim yuav tsum nyob rau hauv lub hnab los yog kaw hlau nruas; kev thauj mus los thoob ntiaj teb xav tau kev tiv thaiv magnesium oxidation.
Tsim nyog daim ntawv thov scenarios rau ntau qib ntawm silicon{0}}magnesium- hlau alloys.
| Qib | Mg/Si/Re | Cov yam ntxwv tseem ceeb | Core Application Scenarios |
| FeSiMg8Re2 | 7%-9%/42%-48%/1%-3% | Muaj zog spheroidizing zog thiab tsis kam mus degradation | Ductile hlau (tsheb crankshafts, cav thaiv) |
| FeSiMg 6 | 5% -7% / 45% -50% / tsis muaj | Tus nqi nruab nrab thiab sib npaug spheroidization | Ordinary ductile hlau (tshuab qhov chaw, yeeb nkab fittings) |
| FeSiMg10Re3 | 9%-11%/40%-45%/2%-4% | Cov magnesium siab thiab cov ntsiab lus tsis tshua muaj hauv ntiaj teb, haum rau siab - sulfur molten hlau | Siab -sulfur seem steel recycled ductile hlau |
Ferrosilicon magnesium alloy feem ntau yog siv hauv cov teb hauv qab no
Kev lag luam metallurgical
Hauv kev tsim steel, nws tuaj yeem siv los ua ib qhoalloy additive. Nws tuaj yeem txhim kho lub zog, hardness, toughness thiab hnav tsis kam ntawm cov hlau, txo cov pa roj carbon ntsiab lus ntawm cov hlau, txhim kho qhov zoo thiab cov qauv ntawm cov hlau, thiab muaj cov nyhuv ntawmdeoxidationthiab desulfurization, txo impurities thiab pores nyob rau hauv steel, thiab txhim kho cov purity ntawm hlau. Thaum ua high-lub zog alloy steel, stainless hlau, thiab tshav kub-cov hlau resistant, ntxiv fesimg alloy tuaj yeem ua tau raws li qhov yuav tsum tau ua ntawm cov hlau sib txawv.
Kev lag luam Foundry
Nws yog ib qho zoo inoculant thiab spheroidizer. Nyob rau hauv cam khwb cia hlau ntau lawm, nws muaj peev xwm txhawb graphitization, txhim kho lub morphology thiab tis ntawm graphite, spheroidize graphite, thiab txhim kho cov neeg kho tshuab zog ntawm castings, xws li lub zog, toughness thiab ductility. Nws tseem tuaj yeem ua kom lub cev muaj zog ntawm cov hlau molten, txo qhov nyiam ntawm cov hlau cam khwb cia, txhim kho qhov zoo thiab cov txiaj ntsig ntawm castings, thiab yog siv dav hauv kev tsim khoom ntawm ntau yam khoom siv, tsheb qhov chaw, yeeb nkab fittings thiab lwm yam castings.
Nonferrous hlau kev lag luam
Nyob rau hauv zus tau tej cov nonferrous hlau xws li txhuas thiab magnesium, silicon ferro magnesium alloy yuav siv tau raws li ib tug alloying caij additive. Nws tuaj yeem txhim kho cov qauv tsim thiab kev ua haujlwm ntawm cov hlau tsis muaj hlau, thiab txhim kho lawv lub zog, hardness, kub tsis kam thiab corrosion kuj. Piv txwv li, ntxivTsis tshua muaj ntiaj teb fesimg alloyrau aluminium alloy tuaj yeem txhim kho hardness thiab lub zog ntawm aluminium alloy, ua rau nws tsim nyog rau kev tsim khoom hauv aerospace, tsheb thiab lwm yam.
Lwm yam teb
Hauv kev tsim khoom ntawm qee cov khoom siv hluav taws xob tshwj xeeb, re ferro silicon magnesium alloy tuaj yeem siv los tsim cov khoom siv hluav taws xob, uas tuaj yeem txhim kho lub zog sib nqus ntawm cov motors thiab transformers, nce qhov ceev thiab lub zog ntawm cov motors thiab transformers, txo qhov kub siab ntawm AC motors, thiab txuas ntxiv lub neej kev pab cuam. Tib lub sijhawm, nws zoo thermal conductivity thiab electromagnetic shielding zog kuj ua rau nws muaj qee yam kev siv hauv cov khoom xws li radiators thiab shielding npog ntawm cov khoom siv hluav taws xob. Tsis tas li ntawd, hauv qee qhov chaw uas yuav tsum muaj siab - lub zog thiab cov khoom siv hnyav, xws li aerospace thiab automotive industries, ferrosilicon magnesium alloys kuj tuaj yeem siv los tsim qee yam tsis yog - cov khoom siv tseem ceeb lossis cov khoom siv los txo qhov hnyav thiab txhim kho kev ua haujlwm tag nrho.
