Dab tsi yog kev siv cov khoom ntsuas kub hauv cov txheej txheem casting?

Temperature Dimensions yog qhov tseem ceeb nyob rau hauv lub casting yam.
Thermocouples tuaj yeem siv dav hauv kev ua haujlwm casting. Nyob rau hauv metallic casting, piv txwv li, qhov kub ntawm cov hlau molten yog qhov tseem ceeb. Kev tswj qhov kub thiab txias tau lav qhov zoo heev thiab kev ncaj ncees ntawm cov castings. Qhov ntsuas kub qhov ntsuas ntsuas ntsuas qhov ntsuas kub ntawm cov hlau molten raws li nws nyob deb nchuav rau hauv pwm. Thermocouples tuaj yeem muab tso rau hauv cov hlau molten los yog nyob ze rau ntawm lub tshuab nqus dej kom muab cov ntsuas kub ntawm lub sijhawm. Qhov no tso cai rau cov neeg ua haujlwm hauv qhov chaw tsim khoom los tswj cov dej kub raws li qhov xav tau. Yog tias qhov ntsuas kub tsuas yog qis dhau lawm, cov hlau yuav tsis mus nrog lub drift kom zoo, ua rau tsis tiav castings lossis tsis xws luag. Ntawm qhov tod tes, yog tias qhov ntsuas kub tsuas yog siab dhau, nws tuaj yeem ua lub hom phiaj tsis txaus ntseeg lossis tej zaum hlawv-los ntawm cov pwm.
Qhov kub ntawm pwm nws tus kheej kuj tseem ceeb heev. Cov pwm sib txawv kuj tseem yuav xav tau cov txheej txheem kub tshwj xeeb kom paub tseeb tias txoj cai khov kho ntawm cov hlau. Cov cuab yeej ntsuas qhov ntsuas kub tuaj yeem siv los tshuaj xyuas qhov ntsuas kub ntawm pwm ua ntej, thaum lub sijhawm, thiab tom qab casting yam. Cov thermocouples tuaj yeem muab tso rau hauv cov kab mob mildew lossis txuas nrog nws hauv pem teb kom ntsuas qhov kub thiab txias. Qhov no ua rau hauv kev ua kom zoo dua cov nqi cua txias thiab txo qhov tsis xws luag uas suav nrog cov kab nrib pleb lossis porosity.
Ntxiv nrog rau cov hlau casting, qhov ntsuas qhov kub thiab txias kuj tseem ceeb heev hauv cov tswv yim sib txawv xws li xuab zeb casting thiab nyiaj txiag casting. Hauv cov xuab zeb casting, qhov kub ntawm cov xuab zeb mildew tuaj yeem cuam tshuam rau qhov ziab thiab hardening ntawm cov xuab zeb, ntxiv rau qhov solidification ntawm cov hlau. Cov cuab yeej ntsuas qhov ntsuas kub tuaj yeem pab xyuas kom meej tias cov xuab zeb mildew nyob rau ntawm qhov ntsuas kub kom zoo rau kev ua yeeb yam ua ntej. Hauv kev muab nyiaj txiag, qhov ntsuas kub ntawm cov qauv siv quav ciab thiab lub plhaub ceramic yog qhov tseem ceeb rau kev kub hnyiab thiab cov dej hauv qab no ntawm cov hlau molten. Cov thermocouples tuaj yeem siv los tshuaj xyuas cov ntsuas kub thiab ua kom paub tseeb tias qhov kev ua tiav tiav.
Thaum lub sij hawm txhim kho thiab optimization ntawm cov tswv yim casting, qhov ntsuas kub yog qhov tseem ceeb. Cov kws tshawb fawb thiab engineers tuaj yeem siv cov ntaub ntawv ntsuas kub los ntsuas cov thermal conductivity ntawm cov cuab yeej casting thiab txhim kho. Cov cuab yeej ntsuas kub qhov ntsuas tau ua rau hauv kev sau cov ntaub ntawv khaws tseg rau kev txhawb nqa kev ua tau zoo thiab zoo heev ntawm kev ua haujlwm casting. Cov thermocouples tuaj yeem siv rau hauv chav kuaj kom ntsuas qhov ntsuas kub kom tsim nyog thiab muab cov ntaub ntawv rau kev kawm thiab kev txhim kho.
