akupanga tirigu kuyenga mu zotayidwa zotayidwa
MALANGIZO:
Akupanga zida zoyenga mbewu's ntchito zazikulu mu ndondomeko ya zotayidwa Sungunulani mankhwala ndi: kuyenga zitsulo njere, homogenizing aloyi zikuchokera, kwambiri kuwongolera mphamvu ndi kutopa kukana kuponya zipangizo, kuwongolera katundu mabuku, kuchepetsa ntchito oyenga tirigu ndi kuchepetsa ndalama.
1. Akupanga kuphatikiza kuchotsa
Ndizovuta kwambiri kuti njira yachitsulo iyandama pamagulu ang'onoang'ono.Pokhapokha atasonkhana m'pamene amayandama.Pamene akupanga mankhwala a zotayidwa njira, yaing'ono inclusions akhoza layered ndi aggregated.Ndi choyenga chambewu, tinthu tating'onoting'ono timayandama kuti tichotse zonyansa.
2. Akupanga degassing
pamene zotanuka kugwedera umayamba mu chitsulo chosungunula, cavitation chodabwitsa amapezeka, chifukwa cha patsekeke kwaiye pambuyo kupitiriza kwa gawo madzi wosweka, kotero mpweya kusungunuka mu madzi zitsulo limafotokoza malo ena.Chifukwa cha zotanuka kugwedera kwa akupanga, kuwira pachimake kwaiye ndi amakula mosalekeza mpaka akhoza kumasulidwa ku chitsulo chosungunuka.
3. Mmene akupanga yoweyula pa khalidwe la kuponya mwana wosabadwayo
Pamene akupanga kugwedera solidification njira ntchito kubala castings, ndi akupanga yoweyula adzabala alternating phokoso kuthamanga kwa mbendera ndi kupanga ndege.Chifukwa cha nonlinear zotsatira, anzake adzatulutsa phokoso otaya ndi yaying'ono phokoso otaya, pamene akupanga opanda kanthu kulankhula adzabala mkulu-liwiro ndege pa mawonekedwe pakati olimba ndi madzi.Zotsatira zonsezi zimatha kudula ndikuwononga ma dendrites, kulikonse komwe kuli malo omveka mkati mwamadzimadzi, zimagwira ntchito.Pogwiritsa ntchito cavitation zotsatira mu ndondomekoyi, akhoza kuyeretsa dongosolo, yeretsani particles ndi homogenize dongosolo.Kuwonjezera mawotchi zotsatira chifukwa kugwedera kuwononga dendrites, ina yofunika ntchito akupanga kugwedera solidification ndi kusintha ogwira supercooling madzi zitsulo.Ma nyukiliyasi ovuta amachepetsedwa.Chifukwa chake, kuchuluka kwa nucleation kumawonjezeka ndipo mbewu zimayengedwa.
