Ua ntej, tshuaj xyuas yog vim li cas txhuas alloy tuag casting yog deformed?
Ib qho yog qhov hloov pauv tag nrho lossis ib nrab, thiab lwm qhov yog qhov ntsuas ntawm qhov tuag tsis sib haum nrog daim duab. Qhov laj thawj rau qhov xwm txheej no muaj raws li hauv qab no: cov qauv txheej txheem tsis zoo thiab qhib pwm thaum ntxov, ua rau tsis muaj peev xwm ua kom nruj nruj, teeb tsa tsis raug ntawm tus pas nrig, tsis muaj zog tsis sib xws thaum rub tawm, lub qhov rooj tsis raug, los yog tuab lub qhov rooj, Nws yooj yim rau deform thaum lub rooj vag raug tshem tawm, thiab thaj chaw hauv cheeb tsam ntawm cov pwm yog ntxhib, ua rau muaj kev tiv thaiv siab. Cov khoom lag luam deformed thaum tshem tawm, thiab cov pwm kub siab dhau, ua rau tsis muaj qhov ruaj khov los yog ntau qhov kev tshem tawm quab yuam, uas ua rau cov khoom deformation.
Rau aluminium alloy tuag castings nrog cov teeb meem deformation no, kev daws teeb meem tuaj yeem txiav txim siab los ntawm cov ntsiab lus hauv qab no, txhim kho cov qauv txheej txheem, tsim nyog kho cov pwm qhib thiab tuav siab, teeb tsa txoj haujlwm tshem tawm thiab tus naj npawb ntawm ejectors, hloov lub rooj vag tuab , thiab ntxiv dag zog rau pwm. Kho, txo qis kev tiv thaiv kev tiv thaiv, tswj cov pwm kub hauv cheeb tsam, thiab tswj cov cua sov sib npaug.
