Txoj Kev Vaj Tse Lub Zog Hlau Casting
Leverage cov peev txheej siab ntawm ** cov duab sib zog ua ke ntawm lub ntiajteb ua kom haum rau ** Los tsim cov khoom siv sib txawv nrog cov khoom siv hlau tsis sib xws thiab tus nqi ua haujlwm. Qhov zoo tagnrho rau kev lag luam uas xav tau lub teeb ci uas tsis muaj cuab yeej siv hluav taws xob, thiab kev lag luam ua kom zoo dua qub, thiab cov kev xav tau tshwj xeeb tom qab.

Yam uas pab
Qib tsim kho:Ua rau cov qauv sib txawv (cov qauv nyias nyias muaj nyias cov kab ke, thiab undercuts los ntawm cov txheej txheem sib xyaw los ntawm kev rov ua cov pwm.
Nqi Them Nqi:Cov pwm ua tas mus li (hlau lossis graphite) txo cov nqi ib nrab rau ib nrab-rau-siab ntau lawm piv rau cov txheej txheem pwm zoo li xuab zeb casting.
Txhim kho cov khoom siv metallurgical:Tswj Filling thiab kev taw qhia kev ua yeeb yam me me, yielding siab dua kev txhim kho muaj zog (}}% txhim kho hauv kev nkees ua hauj lwm vs. Xuab zeb casting).
Thawb qhov ntev ntev ntev:Kev ua tiav ze-net duab qhov tseeb (ct 8- ct10 ib qho iso 8062) nrog kev xav tau saum npoo. 5 μm, txo cov kev xav tau tom qab.
Kev ruaj khov pab tau zoo:Kev haus ntau zog (30-40}}% txo cov vs "
Cov Ntawv Thov
Lub kauj vab lub teeb sheetere:Qhov zoo tshaj plaws rau Aluminium Alloy Cav Cab, thiab cov khoom siv roj teeb, thiab cov roj teeb} mm) nrog iso ct9 qhov ruaj khov thiab<1% porosity.
Aerospace Turbine Ancillaries:Cov ntaub pua nroog npib-raws li superally coj vanes thiab combustor Liners uas muaj cov cim kev nkag rau hauv {1}} degree kev ua haujlwm kub.
Hydraulic / valve tshuab:Ua siab tawv-resistant bronze / ductant hlau valve lub cev |
Kho mob Impant Prototyping:Pab kom cov nqi tsim nyog titanium (ti -6 v) __} v)} v) __sopraces rau biocompatibility soj ntsuam ua ntej machining.
Cov Lus Nquag Nug (FAQ)
Q: Yuav ua li cas lub ntiajteb txawj nqus camting txawv txawv ntawm siab-siab tuag casting (HPDC) rau cov geometries ntau?
A: Lub ntiajteb txawj nqus casting siv cov ntiajteb txawj nqus rau pwm thiab roj kev ua kom muaj zog thiab cov roj ua kom zoo rau nruab nrab ntau lawm (5k-50k chav nyob). Hauv kev sib piv, HPDC kev cia siab rau qhov kev kub ceev, kev txhaj tshuaj kub siab (30-60 m / s) rau qhov kev pheej hmoo tab sis kev pheej hmoo ntawm cov nqi.
Q: Cov alloys twg yog qhov zoo tshaj plaws rau kev sib tsoo sib tsoo?
A: Cov alloys zoo tshaj plaws suav nrog aluminium (A356 rau cov khoom siv hydraulic), thiab tshwj xeeb} v (kev kho mob) thiab inconel 718 (aerospace). Tsis txhob muaj cov roj av qis qis (piv txwv li, ib co mg alloys nrog<1.5% fluidity index).
Q: Dab tsi yog qhov tseem ceeb phab ntsa tuab tsim cov cai?
A: Tsawg kawg cov phab ntsa thickness: 2. {0 hli rau txhuas, 3.5 mm rau 1559-1). Tswj ib qho 1: 3 tuab piv ntawm ntu uas nyob ib sab los tiv thaiv kev ua kua kub kub. Sim raws li yuav tsum tau ua rau phab ntsa<2.5 mm or aspect ratios >8:1.
Q: Graphite thiab hlau pwm sib piv hauv cov nyiaj thiab tus nqi?
A: Graphite pwm (ISO {-63 qib) kawg 8k-12% tus nqi qis dua tab sis tsis ua tiav nrawm dua (85% saum ceev nyiaj khaws cia tom qab 5k cmles). H13 steel-100k-100k + mus txog 50k-100% ua tiav kev khaws cia tom qab 20k cycles, zoo tagnrho rau siab ntim ntau lawm.
Q: Dab tsi cov qauv txo qhov porosity hauv intricate cas?
A: Degas melts rau<0.15cc H₂/100g (ASTM E505), use tilt-pouring systems (<0.8 m/s fill speed), and apply Hot Isostatic Pressing (HIP) at 900°C/100MPa to eliminate 95% of porosity, ensuring compliance with ASTM E466 fatigue standards.
