Khoom Taw qhia
Ferro silicon magnesium alloy yog ib qho alloy ua los ntawm kev ntxiv calcium, magnesium, thiab lwm yam khoom rauferro silicon. Fesimg alloy yog dab tsi peb hauv kev lag luam foundry feem ntau xa mus ua tus neeg sawv cev spheroidizing. Nws txoj haujlwm yog yooj yim: hloov flake graphite rau hauv spheroids, ua cam khwb cia hlau "tawv" es tsis txhob "nkig". Nws yog lub teeb tsis tshua muaj hauv ntiaj teb magnesium silicon ferro alloy nrog lub zog txhua yam thiab muaj zog deoxidation thiab desulfurization zog.
Lub ntiaj teb tsis tshua muaj FeSiMg alloy yog siab -kev ua tau zoo alloy nrog ntau yam tshuaj muaj pes tsawg leeg thiab qib, suav nrog cov feem loj ntawm cov ntsiab lus xws li RE, Mg, Ca, Si, Mn, Ti, Fe. Piv txwv li, qhov loj feem ntawm Mg hauv FeSiMg6RE1 yog 0.5 ~<2.0%, Ca is 5.0~7.0%, Si is 1.5~3.0%, and the rest is Fe. The rare earth content of this alloy is in the range of 4.0%~23.0%, and the magnesium content is in the range of 7.0%~15.0%.
Qhov ntau thiab tsawg muaj xws li 5-10mm, 5-15mm, 5-25mm, thiab 5-30mm. Kev cai qhov ntau thiab tsawg kuj tuaj yeem kho tau.
tshuaj muaj pes tsawg leeg
| Casting Hom | Qib pom zoo | Mg cov ntsiab lus | Rare ntiaj teb cov ntsiab lus | |
|---|---|---|---|---|
| Ordinary ductile hlau castings | QRMg7HRE 2 | 6-8% | 1.5-2.5% | Muaj magnesium txaus, cov ntsiab lus tsis tshua muaj hauv ntiaj teb, cov nqi zoo tshaj -effectiveness |
| Siab -lub zog ductile hlau castings | QRMg8HRE3 | 7-9% | 2.5-4.0% | Qhov sib npaug ntawm magnesium thiab tsawg lub ntiaj teb sib piv ua rau muaj tus nqi spheroidization siab |
| tuab thiab loj -section ductile hlau castings | QRMg8HRE5 | 7-9% | 4.0-6.0% | Cov ntsiab lus tsis tshua muaj hauv ntiaj teb muab muaj zog tiv thaiv fading |
| Ntxiv - tuab thiab loj -section / siab{2}} kev ua tau zoo castings | QRMg8HRE7 | 7-9% | 6.0-8.0% | Cov ntsiab lus tsawg tshaj plaws hauv ntiaj teb kom ntseeg tau siab spheroidization tus nqi hauv cov tub ntxhais |
| Siab -sulfur molten hlau lossis cov txheej txheem tshwj xeeb | QRMg10HRE7 | 9-11% | 6.0-8.0% | Cov ntsiab lus magnesium siab them nyiaj rau sulfur -induced burn-tawm |
Kev siv tseem ceeb
1, Alloy additives:
Tsis tshua muaj ntiaj teb silicon magnesium ferro alloy feem ntau yog siv los ua ib qhoalloy additivehauv steel metallurgy. Qhov sib ntxiv ntawm silicon thiab magnesium tuaj yeem txhim kho cov khoom siv ntawm cov hlau, xws li lub zog, hardness thiab corrosion kuj, thiab tseem txhim kho kev ua haujlwm ntawm cov hlau.
2, Lub luag haujlwm ntawm lub ntiaj teb tsis tshua muaj:
Qhov sib ntxiv ntawm cov ntsiab lus tsis tshua muaj hauv ntiaj teb rau cov hlau tuaj yeem txhim kho thermal stability thiab corrosion kuj ntawm cov hlau thiab txhim kho kev ua haujlwm ntawm cov hlau nyob rau hauv qhov kub thiab txias.
Tuam Tshoj yog ib lub teb chaws ntxov tshaj plaws los tsim, tsim thiab sivtsawg ntiaj teb ferrosilicon alloys. Nrog ntau cov peev txheej hauv ntiaj teb tsis tshua muaj, tsis tshua muaj lub ntiaj teb hloov kho yog siv los kho cov qauv ntawm cov chromium cam khwb cia hlau siab, thiab cov txheej txheem kho cua sov siv los txhim kho nws cov kev ua tau zoo.
Raws li cov khoom siv tshwj xeeb alloy, RE ferro silicon magnesium alloy muaj cov txiaj ntsig tseem ceeb hauv cov hlau metallurgy thiab lwm yam kev lag luam. Los ntawm nws qhov tshwj xeeb muaj pes tsawg leeg thiab kev ua tau zoo, nws ua tau raws li cov kev xav tau ntawm kev ua haujlwm siab ntawm -cov khoom siv steel.
FAQ
Q: Yog tias tus neeg sawv cev spheroidizing tau ntub, nws puas tseem siv tau tom qab ziab?
A: Nws tsis pom zoo. Damp spheroidizing cov neeg ua haujlwm muaj qee qhov oxidized magnesium, thiab ziab yuav tsis rov qab los. Siv lawv yuav txo cov nyhuv spheroidizing thiab tej zaum yuav tsim porosity. Yog li ntawd, ib zaug damp, nws yog qhov zoo tshaj kom muab pov tseg.
Q: Kuv puas yuav tsum xaiv qhov loj lossis me me rau tus neeg sawv cev spheroidizing?
A: Nws nyob ntawm qhov loj ntawm lub molten hlau ladle. Rau me me ladles (hauv qab 1 tuj), xaiv 5-15mm particles kom yaj sai; rau cov ladles loj (tshaj 5 tons), xaiv 10-30mm particles rau cov tshuaj tiv thaiv ruaj khov thiab tsis tshua muaj hlawv.
Q: Kuv yuav xam tus nqi ntawm tus neeg sawv cev spheroidizing li cas?
A: Nws feem ntau yog nyob ntawm cov ntsiab lus ntawm leej faj ntawm cov hlau molten qub. Qhov siab dua cov ntsiab lus ntawm sulfur, ntau dua qhov xav tau ntawm spheroidizing tus neeg sawv cev. Cov mis mos dav dav yog: Spheroidizing tus neeg saib xyuas ntau npaum li cas=(Original sulfur - Target sulfur) × 1.5-2.0. Piv txwv li, yog hais tias tus thawj sulfur ntsiab lus yog 0.03% thiab lub hom phiaj sulfur ntsiab lus yog 0.01%, tus neeg sawv cev spheroidizing ntau npaum li cas yog kwv yees li 1.0% -1.5%.
Q: Puas yog qhov zoo ntawm koj cov spheroidizing cov neeg ua haujlwm zoo ib yam ntawm cov khoom siv?
A: Kev sib koom ua ke yog qhov tseem ceeb. Peb sim txhua pawg nrog lub spectrometer ua ntej xa zaub mov kom paub meej tias qhov hloov pauv ntawm magnesium thiab cov ntsiab lus tsis tshua muaj hauv ntiaj teb raug tswj nyob rau hauv qhov tsawg heev. Cov ntaub ntawv pov thawj nrog rau txhua qhov khoom xa tuaj.
