Hauv kev tsim khoom ntawm cov roj teeb fais fab rau cov tsheb hluav taws xob tshiab, Aluminium Tos Vuam yog qhov tseem ceeb uas cuam tshuam rau kev nyab xeeb roj teeb thiab ua haujlwm. Tsoos vuam txoj kev muaj zog rau cov teeb meem xws li pores thiab txias vuam, thaumHigh-zaus Inverter Vuam Machinetau dhau los ua cov tshuaj tseem ceeb hauv kev lag luam nrog lawv cov txiaj ntsig xws li cov lus teb siab nrawm thiab muaj zog tswj tau.
1. Kev lag luam mob cov ntsiab lus ntawm Aluminium tab vuam
① Cov kev nyuaj tau coj los ntawm cov khoom siv
● Thermal conductivity: Lub thermal conductivity ntawm aluminium yog peb zaug ntawm cov hlau, thiab poob sai sai ntawm cov cua sov ua rau nkag tsis tau
Hinding Cov Zaj Duab Xis (Melting taw tes 2050 degree) hinders qhov tsim ntawm Molten pas dej
Kev nyiam ua hluav taws xob tawg: grain ciam tsam liquefaction ntawm kev kub siab yog nquag rau tawg
Cov kev txwv ntawm cov kev sib tw vuam txoj kev
| Vuam txheej txheem | Teeb meem tseem ceeb | Puas tus nqi |
| Zoo tib yam mig vuam | Ntau ntawm lub cim, txom nyem weld tsim | 15%-20% |
| AC Tig Vuam | Qeeb ceev, nyuaj rau ntxuav oxide txheej | 10%-15% |
| Ultrasonic Vuam | Tsuas yog tsim nyog rau cov ntawv nplaum nyias txhuas (<0.3mm) | Cov khoom siv siab |
2. Cov kev sib tsoo thev naus laus zis ntawm high-zaus inverter vuam tshuab
① Cov Ntsiab Lus Zoo
Ultra-ceev teb ceev ceev ceev (> 100kHz): Muaj tseeb tswj tau cov nthwv dej tam sim no txhua tus mem tes kom sudpress
HWJ HOV NTUJ TSHWJ XEEB: Preheating (rhuav Oxide Txheej) → Key Txias (Anti-Back)
Cov teeb liab digital ua (DSP): Kev tshuaj xyuas lub sijhawm tiag tiag ntawm arc xwm txheej thiab tsis siv neeg them nqi ntawm voltage hloov pauv
② Cov Ntsiab Lus Tseem Ceeb
| Tsis | Pom zoo tus nqi | Hauj loo piav qhia |
| Hov ntau | 50-100 cmz | Txo cov tswv yim cua sov, txo kev deformation |
| Mem Tes Dav | {{0 {}}. {5-2 ms | Tswj Melting Qhov tob |
| Pib tam sim no | 30% ntawm ncov tam sim no | Tswj arc ruaj khov |
| Cov roj tiv thaiv | Ar +30% nws | Txhim khu molten da dej |
3. Cov teeb meem thiab countermeasures
① Weld Porosity
Speer Hydrogles Blackolves rau hauv Pas Dej Molten (Aluminen
● Kev txheeb xyuas cov khoom: Siv cov kev ua tsis huv muaj zog argon (ntau dua los yog sib npaug rau 99.999%); Preheat rau 120 degree ua ntej vuam (txo hydrogen solubility)
② Cov Vuam Txias (Tsis Muaj Cai)
● Cov laj thawj: Oxide txheej tsis raug tshem tawm kiag li
● Kev txheeb tshuaj: Ntxiv rau Arc stirring ua haujlwm (DSP tswj arc viav); siv ramp tam sim no (qeeb sawv thiab qeeb qeeb kom tsis txhob cua sov tam sim thiab cua txias)
High-zaus inverter vuam siv lub tshuab ua kom yooj yim txog kev ntseeg tau thiab kev ua tau zoo ntawm txhuas tab vuam, cov lus teb ceev, thiab ntau pab txhawb kev tsim tawm. Kom tag nrho cov ntaub ntawv vuam ntxiv, thov hu rau peb pab pawg!
