Lub high-temperature alloy nyias-walled casing casting muaj ib tug complex ob-ntiv nplhaib qauv nrog ntau yam hollow kev them nyiaj yug daim hlau thiab tsis sib luag phab ntsa thickness, uas ua rau lub casting rau shrink inconsistently nyob rau hauv lub txias txheej txheem, ua rau lub net qhov ntev ntawm lub puab thiab sab rings. lub casting yuav tsis ruaj khov thiab deviating los ntawm tus tsim drawings. Xav tau. Los ntawm kev txheeb xyuas tag nrho cov txheej txheem ntawm cov casting thiab qhov cuam tshuam ntawm cov txheej txheem kev npaj ntawm qhov shrinkage ntawm casting, peb pom cov laj thawj tseem ceeb thiab cov cai rau kev sib txawv ntawm cov casting los ntawm cov qauv tsim, thiab rov ntsuas dua thiab cov ntaub ntawv txheeb xyuas cov pwm, Cov khoom siv quav ciab, thiab cov khoom hlau los tawm tswv yim kev txhim kho thiab kev coj ua Tom qab tshawb xyuas cov phiaj xwm, qhov kev sib tw casting tau zoo dua qub thiab ua tau raws li cov qauv tsim.
Txhawm rau ua kom tau raws li qhov xav tau ntawm lub teeb yuag thiab tus nqi qis aero-engine cov qauv, kev lag luam aviation tau txais kev kub siab alloy nyias-walled casing ib qho tseem ceeb precision casting tshuab los hloov cov casing manufacturing tshuab ntawm cov khoom sib cais thiab sib dhos. Qhov tseem ceeb casting ntawm high-temperature alloy nyias-walled receivers yog txawv ntawm casting nyob rau hauv ib txwm kev txiav txim zoo. Tsis tsuas yog yuav tsum tau tsim, tab sis kuj cov duab thiab qhov ntev ntawm qhov raug ntawm cov casting yuav tsum raug tswj kom tau raws li qhov yuav tsum tau ntawm cov khoom sib dhos. K4169 high-temperature alloy nyias-walled casing casting peb tsim yog ib tug neeg sawv cev ntawm no hom ntawm casting. Tsis tsuas yog lub sab hauv thiab sab nraud metallurgical zoo thiab nto zoo ntawm cov casting yuav tsum tau siab, tab sis qhov tseeb qhov yuav tsum tau ntawm lub casting yog txawm stricter. Txoj kab uas hla ntawm qhov casting yog φ8{10}}0mm. Nyob rau hauv cov nqe lus ntawm qhov ntev, tus nqi kam rau ua yog 0.6 hli, thiab nws tau ua kom ntseeg tau tias qhov chaw nkag thiab tso tawm ntawm qhov chaw casting ntws raws li cov qauv tsim. Nws koom ua ke qhov tseeb qhov yuav tsum tau muaj ntawm kev tsim khoom xws li casting, ua, thiab sib dhos, tag nrho cov lav los ntawm casting, thiab qhov ntev casting Control yog qhov nyuaj heev. Nyob rau hauv cov txheej txheem siv tiag tiag ntawm kev xaiv thiab kho cov pwm tsim cov qauv, kev tsim raws li kev ua ib txwm muaj tsis tuaj yeem ua tau raws li qhov kawg ntawm cov khoom.
Nyob rau hauv kev pom ntawm qhov tseeb hais tias lub puab thiab sab nplhaib qhov ntev ntawm high-temperature alloy annular casing casting yuav tsis tau raws li qhov yuav tsum tau tsim, ib tug series ntawm kev tshawb fawb ua hauj lwm tau ua tiav. Los ntawm kev tsom xam ntawm cov txheej txheem casting, solidification, tooling, casting thiab lwm yam dimensional ntsuas, cov ntaub ntawv tsom xam, simulation tsim, thiab lwm yam., Tom qab tshawb xyuas lub shrinkage tus nqi ntawm nyias-walled annular structural qhov chaw nrog ceramic cores thiab qhov sib txawv ntawm shrinkage ntawm txawv. flow channel cross-sections, cov pwm tsim tsis tau hloov kho thiab cov txheej txheem txhim kho pwm tau txiav txim siab los xyuas kom meej tias qhov loj me me tau ua raws li cov qauv tsim.
