Yog vim li cas rau lub deformation ntawm alumina sib tsoo pob thaum lub sij hawm roasting txheej txheem tej zaum yuav hais tias lub particle loj tis ntawm alumina hmoov yog dav heev, lub particle loj dhau lawm, los yog xaiv thiab ntau npaum li cas ntawm additives nyob rau hauv lub alumina hmoov yog tsis tsim nyog.
Lub ntsiab yog vim li cas rau qhov tawg ntawm cov pob zeb sib tsoo tom qab calcination yog qhov tsis xws luag ntawm alumina sib tsoo cov khoom, uas kuj muaj feem xyuam rau lub shrinkage ntawm cov khoom sib tsoo. Rau cov laj thawj ntawm qhov tsis sib haum xeeb ntawm cov pob steel, thov xa mus rau kev tshuaj xyuas ntawm qhov ua rau roasting deformation. Thaum lub shrinkage tus nqi tsis sib haum, yog tias muaj qhov tsis xws luag, qhov tsis xws luag yuav ua rau lub hauv paus tawg, thiab qhov tawg ntawm qhov tawg ua rau lub pob steel tawg.
Thaum cov nplej loj tuaj txawv txav, muaj ntau qhov pores nyob rau hauv cov nplej loj heev, uas nyuaj rau kev tawm ntawm cov nplej mus rau thaj tsam ntawm cov nplej. Qhov no yuav ua rau nws nyuaj rau cov ntaub ntawv ceramic kom ua tiav qhov ntau dua thiab tsis xwm yeem ntau yam khoom, feem ntau cov khoom siv tshuab (pob txha pob hluav taws xob, lub zog yooj yim, thiab lwm yam).
Cov txiaj ntsig tau pom tias qhov ntom ntawm alumina sib tsoo pob tsis sib xws thaum lub sij hawm molding txheej txheem (hmoov agglomeration, semi-tiav khoom siab gradient, thiab additives tsis zoo li qub), thiab qhov ceev tsis yog uniform thaum lub sij hawm roasting txheej txheem.
