{{0 {{}} Q: Dab tsi yog cov khoom tseem ceeb raw rau txhuas billet ntau lawm?
A: Cov ntaub ntawv tseem ceeb muaj xws li:
Thawj Aluminium (99.7% Ntshiab ntawm Electrolytic Txo)
Alloying ntsiab (SI, CU, CU, ZN, MN thiab lwm yam.)
Rov qab ua dua cov ntawv nyeem (kom txog 50% ntawm pub zaub mov)
Grains refinters (al-b rods)
Degassing cov neeg sawv cev (nitrogen lossis argon nrog chlorine)
Cov ntaub ntawv no tau raug xaiv thiab ua kom tiav kom tau txais kev ntsuas Alloy zoo li 6063, 6061, 6063, 6061, los yog kua hlau los yog kua hlau los yog kua hlau los yog kua hlau los yog kua
{{0 {{}} Q: li cas lub yaj melting thiab alloying ua haujlwm rau kev npaj billet?
A: Cov txheej txheem cuam tshuam nrog:
Them: Chaw thau khoom cov khoom nyoos rau hauv roj-phom lossis hluav taws xob rurnaces ntawm {}}} degree
MELTING: Ua kom tiav liquefaction yuav siv 2-4}} teev nyob ntawm qhov muaj peev xwm cua sov
Aloyying: meej ntxiv ntawm cov ntsiab lus kom ua tiav cov hom phiaj muaj pes tsawg leeg
Nplawm: electromagnetic los yog tshuab sib xyaw ua kom homogeneity
Kuaj: Spectrometer txheeb xyuas cov lus qhia txog cov tshuaj muaj tshuaj
Hloov Kho: Kawg tweaks rau cov ntsiab lus yog xav tau
Cov nroj tsuag niaj hnub siv cov roj hlawv loj dua rau kev txuag hluav taws xob (txog li 50% roj txuag) thiab cov dosing dosing rau alloying.
{{0 {}} Q: Yam kev kho mob huv si tau siv rau kev ua haujlwm ntawm kev ua ntej ua ntej cam khwb cia?
A: Peb qhov tseem ceeb ua kom muaj cov kauj ruam:
Degassing: Rotating Impellers Txhaj Nitrogen / Argon Kom Tshem Tawm Hydrogen (Phiaj:<0.15ml/100g Al)
Fluxing: Salt fluxes tshem tawm oxides thiab tsis yog xim hlau suav nrog
Pom: ceramic pham lim (30-50 ppi) ntes cov khoom seem
Cov ntsiab lus siab tshaj plaws nyiam Snif (spinning nozzle inert flotation)}}}}}}}} 08m. 08m {}}
{{0 {}} Q: Npaum li cas yog txhuas beets pov rau hauv cov kab ntau lawm?
A: Txoj kev tseem ceeb yog DC (ncaj ntov ntov) casting:
Molten Aluminium (690-710 degree) nkag mus rau hauv dej-txias pwm
Solidification pib tam sim ntawd nrog dej txau cua txias
Billts yog txuas ntxiv mus tsis tu ncua ntawm 50-200 hli / min
Cov Duav Diameters: {{3-10 nti (75-254 mm)
Ntev: {{4-7 meters rau kev tuav yooj yim
Cov yam tseem ceeb muaj xws li:
Cua txias Dej Flow: {50-100 m³ / h ib tuj ntawm txhuas
Casting ceev hloov raws li lub taub
Rho Tawm Qib Kev Tswj Hauv Pwm (± 1mm)
{{05. Q: Dab tsi tom qab-casting kev kho yog qhov yuav tsum tau rau txhuas billets?
A: Peb Qhov Tseem Ceeb Kev Kho:
Homogenization:
Cua sov rau 500-580℃rau 4-12 teev
Tshem tawm micro-soobration
Txhim kho cov extrudability
Scalping:
Tshem tawm 3-5 mm deg deg txheej
Tshem tawm saum npoo degrom
Txhim kho cov nplaim zoo ntawm extruded profiles
Soj Ntsuam Zoo:
Ultrasonic kuaj rau sab hauv tej yam
Tshuaj lom neeg cov khoom siv tshuaj lom neeg
Macrostructure kev kuaj xyuas
Cov txheej txheem no ua kom muaj cov tshuaj tua kab mob ntxiv rau qhov raug, cov khoom lag luam saum npoo av .
