Kuponyera kosalekeza kumakhazikika pang'onopang'ono ndikulimbitsidwa ndikukakamizidwa kulowa m'malo otentha, komanso slab panthawi yolimba kuti athe kupirira kukhazikika kwamphamvu, kuzizira kozizira, kutsika kwapang'onopang'ono, kupsinjika, kupsinjika kwamatenthedwe chifukwa cha kutentha, chitsulo chotulutsa kupsinjika kwa hydrostatic kumayambitsa. ndi kupsinjika ndi kupindika ndi kuwongola kusagwira bwino kwa zida kunayambitsa kupsinjika kowonjezereka kwa njira ya thermo-mechanical.
Pakutulutsa kosalekeza, kuchepetsa mphamvu ya kuzizira kwachiwiri komwe kumagwiritsa ntchito kuzizirira kofooka kumatha kuchepetsa ndikuletsa ming'alu.Kuchepetsa kuzirala kungachepetse nkhawa matenthedwe chifukwa cha kutentha gradients mkati ndi kunja lalikulu chitsanzo chifukwa, komanso kungachititse zitsulo gawo lapansi precipitates ukuwonjezeka, kuchepetsa chiwerengero cha malire a tirigu pamodzi precipitates zabwino ndi ziletsa mpweya wabwino mauna ferrite, pulasitiki. ndi bwino.otsika kupsyinjika mlingo mosalekeza kuponya, kukula kwa kupsyinjika mlingo kwambiri zimakhudza kutentha kwa zinthu pulasitiki.
Kuponyera ndi njira yoziziritsa yosagwirizana, yomwe imawonetsedwa mosagwirizana kuyambira pakuzizira kwachiwiri kwa crystallizer panjira yonseyo, makamaka mu:
(1) Chigoba choyamba cholimba mu nkhungu meniscus chomwe chinapangidwa pa kuzizira ndi kulimbitsa shrinkage chifukwa cha khoma la nkhungu, ndiye kuthamanga kwachitsulo chachitsulo chosungunuka kutembenuza kupanikizika kwa nkhungu, kotero kuti ngati kukhudzana pakati pa awiriwo - kunja. - njira yokhazikika yolumikizirana.Fluxes mu solidified chipolopolo makulidwe aumbike padziko m'goli, chifukwa m'goli ndi m'goli kukula kwa nkhungu kuzirala anavutika solidified chipolopolo ndi chifukwa chachikulu cha slab pamwamba ming'alu ndi khungu ming'alu.Mu nkhungu anapanga khama zosiyanasiyana monga kulamulira mlingo, ndi njira zina kusintha chitetezo cha makhalidwe slag akhoza kuchepetsa izi inhomogeneity kuzirala kumlingo wakuti, sangathe kuthetsedwa.
(2) slab mu yachiwiri kuzirala zone ya chovomerezeka kutsitsi kuzirala madzi pachimake, chifukwa kuzirala ndi cheza kutentha kutengerapo mu mlengalenga, kuzirala kutsitsi nozzles kwa kuzirala ndi wodzigudubuza wodzigudubuza ndi wosiyana kuzirala, ngati m'modzi kuzirala kwambiri, zidzachititsa kukula. za ntchito yomwe ilipo ya ming'alu yaying'ono, kuphulika kwa slab, ndi kuyambitsa ming'alu yamkati.Kuziziritsa kosayenera kwamadzimadzi pachimake kumayambitsa kutentha kwanthawi yayitali kosayenera, kutentha kwapamwamba kwa slab pakuwongoka kukakhala ndi kutentha kwambiri komwe kumakhala kosasunthika, komwe kumakonda kuchita ming'alu yopingasa, kuziziritsa kosagwirizana pakukhazikika koyambira kwa oscillation mark through ndizovuta kwambiri.
