Hauv kev tsim cov khoom siv hluav taws xob hauv tsev, kev tswj xyuas zoo yog qhov tseem ceeb hauv kev ua kom ntseeg tau cov khoom lag luam thiab kev pabcuam lub neej. Tuag casting ntau lawm muaj molten hlau txhaj, siab - kub thiab siab - siab txias, thiab tom qab machining. Kev sib txawv ntawm txhua kauj ruam tuaj yeem ua rau muaj qhov tsis xws li porosity, shrinkage kab noj hniav, tawg, lossis deformation. Yog li ntawd, tsim kom muaj kev tswj xyuas kom zoo yog qhov tseem ceeb.
Ua ntej, kev tswj cov khoom raw khoom zoo yog qhov tseem ceeb. Aluminium, zinc, thiab magnesium alloys siv rau kev tuag casting yuav tsum ua kom tau raws li cov qauv kev cai kom tsis txhob muaj impurities los yog tsis sib xws muaj feem cuam tshuam rau fluidity thiab mechanical zog. Melting kub thiab tuav lub sij hawm kuj xav tau kev tswj nruj kom ntseeg tau tias cov hlau tsis sib xws thiab tiv thaiv kev suav nrog lossis cov pa roj nkag mus rau hauv pwm.
Thaum lub sij hawm tsim khoom, kev tswj cov txheej txheem yog qhov tseem ceeb tshwj xeeb. Siab -Kev txhaj tshuaj ceev, kev txhaj tshuaj siab, pwm kub, thiab lub sijhawm txias yog txhua yam uas cuam tshuam ncaj qha rau qhov zoo. Niaj hnub nimno tuag casting ntau lawm feem ntau siv automated thiab ntse tswj systems, ua tiav cov txheej txheem stability thiab ib feem sib xws los ntawm tiag tiag - sij hawm xyuas thiab parameter hloov. Pwm tu thiab calibration tseem ceeb sib npaug; hnav lossis deformed pwm tuaj yeem ua rau qhov sib txawv ntawm qhov sib txawv thiab qhov tsis xws luag.
Cov txheej txheem tshuaj xyuas yog lub hauv paus ntawm kev tswj kom zoo. Cov kev tshuaj ntsuam xyuas feem ntau suav nrog kev tshuaj xyuas qhov muag, ntsuas qhov ntev, thiab tsis yog - kuaj kev puas tsuaj. Kev kuaj pom pom tuaj yeem pom qhov tsis xws luag xws li porosity, tawg, thiab burrs; Kev ntsuas qhov loj me kom ntseeg tau tias qhov chaw ua tau raws li cov qauv tsim; thiab tsis yog- kuaj kev puas tsuaj (xws li X-ray thiab ultrasonic kuaj) tuaj yeem kuaj pom qhov tsis xws luag. Rau qhov tseem ceeb, kev ntsuam xyuas cov cuab yeej cuab tam, xws li tensile, hardness, thiab kev ntsuam xyuas cuam tshuam, kuj yuav tsum tau xyuas cov khoom siv thiab cov khoom siv.
