Thaum ntsuas kub ntawm qhov chaw pov tseg nti hauv qab theem ntawm cov khoom ua kab, qhov nplaum plhaub nplaum tawv plhuaj rau sab hauv cov hlau, thiab cov neeg khiav dej khov hauv khib nyiab yog khov.


Thaum twg ntxiv txias, cov kua hlau nyob hauv lub plhaub tawv tawv vim qhov txo ntawm qhov kub thiab txias, uas yog cov tshuaj ua kom lub zog ntawm qhov tawv plhaub. Nyob rau tib lub sij hawm, qhov ruaj khov tawv plhaub shrinks vim qhov txo ntawm qhov kub thiab txias. Yog hais tias lub ntim txo ntawm lub cev ua kua los ntawm cov roj ua kua thiab qhov sib zog ua kom sib zog hauv cov tawv plhaub yog sib npaug txo ntawm qhov ntim ntawm cov peev casting , lub plhaub lawm yog tseem nyob ze nrog cov ua kua hauv cov tawv plhaub, thiab tsis muaj qhov ntswg qhov yuav tshwm sim. Txawm li cas los xij, cov kua ntsws thiab ua kom tsis muaj zog ntawm cov hlau txaij ntau tshaj qhov sib txoos ntawm lub plhaub tawv ncauj, yog li cov kua yuav poob tawm los ntawm sab saum toj ntawm lub plhaub tawv ncauj. Nyob hauv succession, lub plhaub tawv tawv yuav thickened, cov kua ua kua yuav poob qis dua, tag nrho cov hlau solidification, nyob hauv ib sab ntawm lub casting tsim ib lub khob khoob-puab zoo li lub qhov ntswg. Thaum cov cua kub mus rau chav tsev kub tsis tu ncua, qhov ntim ntawm tag nrho cov casting txo tsis tu ncua, thiab lub meej ntim ntawm shrinkage qhov txo kuj, tab sis qhov ntim ntawm qhov casting seem unchanged. Yog hais tias tus ris nce siab nyob rau saum toj ntawm qhov casting, lub qhov ntswg yuav tsiv mus rau tus riser.


Hauv cov ntsiab lus, vim li cas ho tseem ceeb rau lub hauv paus ntawm lub hauv paus cog qoob loo yog tias cov kua ntsws thiab kev sib zog ua kom shrinkage ntawm lub phom yog ntau ntau dua qhov sib txuam; tej qhov xwm txheej rau lub hauv paus ntawm qhov ntswg yog tias qhov casting solidifies txheej los ntawm txheej los ntawm qhov chaw mus rau sab hauv, thiab lub qhov ntsws qhov yau muaj concentrated nyob hauv qhov kev sib nraus kawg.
