Casting yog ib qho ntawm feem ntau siv kev lag luam rau ua npuas ncauj ceramic lim. Nws txoj haujlwm yog ua kom cov turbulent thiab tumbling molten hlau ua du, zoo ib yam thiab huv si tom qab dhau los ntawm lub honeycomb qhov ntawm cov npuas dej ceramic, yog li zoo heev txo cov casting rejection tus nqi tshwm sim los ntawm casting defects xws li non-metallic inclusions thiab txuag nqi ntau lawm.

Cov ntaub ntawv raw khoom zoo heev thiab cov cuab yeej ua haujlwm siab heev kom ntseeg tau tias cov lim dej muaj qhov ruaj khov ntawm qhov ntev, thiab tib lub sijhawm ua tau raws li qhov yuav tsum tau ua ntawm phau ntawv qauv thiab cov tshuab ua haujlwm zoo dua, thiab xyuas kom meej tias cov khoom lag luam zoo ntawm cov khoom tsim tau raws li cov qauv zoo thoob ntiaj teb. Alumina ua npuas ncauj ceramic lim, haum rau kub 1250 ℃, haum rau pom thiab purification ntawm txhuas thiab hlau daws. Txhawm rau kom ua tau raws li qhov yuav tsum tau ua kom zoo ntawm txhuas castings, kev siv cov alumina ua npuas ncauj ceramic lim (phaj) yog qhov tseem ceeb dua. Cov ntxaij lim dej kuj tau siv dav hauv cov xuab zeb zoo tib yam xws li ntub pwm casting thiab pwm mus tas li xws li tsheb txhuas qhov chaw casting.
