The akupanga zitsulo Sungunulani processing zida wapangidwa ndi akupanga kugwedera mbali ndi akupanga jenereta: ndi akupanga kugwedera mbali ntchito kupanga akupanga kugwedera – makamaka kuphatikizapo akupanga transducer, akupanga nyanga ndi chida mutu (kutumiza mutu), ndi kufalitsa izi kugwedera mphamvu kwa zitsulo. sungunula.

Ntchito ya ultrasonic metal melt:

1. Kuchotsa zonyansa: ndizovuta kwambiri kuti zing'onozing'ono zophatikizidwa muzitsulo zamadzimadzi ziyandama mmwamba.Pokhapokha atasonkhana m'pamene kumakhala kosavuta kuyandama.Pogwiritsa ntchito akupanga zitsulo Sungunulani mankhwala zida kuwonjezera akupanga mu njira, ndi akupanga ataima yoweyula angapange kuphatikiza ufa mu njira delamination ndi agglomeration bwinobwino.

2. Akupanga degassing: akupanga amakhudza kwambiri kuchotsa mpweya ku chitsulo chosungunuka.Akupanga zotanuka kugwedera akhoza kwathunthu degass aloyi mu mphindi zochepa.Pamene akupanga kugwedera umayamba mu chitsulo chosungunuka, amapezeka kuti pali cavitation chodabwitsa, chifukwa cha patsekeke kwaiye pambuyo kupitiriza kwa madzi gawo wasweka, kotero mpweya kusungunuka mu madzi zitsulo limafotokoza mmenemo.

3. Mbewu kuyengedwa: popanga castings ndi akupanga kugwedera solidification njira, ndi akupanga yoweyula adzatulutsa zabwino ndi zoipa alternating phokoso kuthamanga ndi mawonekedwe ndege.Pa nthawi yomweyo, chifukwa nonlinear tingati adzatulutsa phokoso otaya ndi yaying'ono phokoso otaya, pamene akupanga cavitation adzabala mkulu-liwiro yaying'ono ndege pa mawonekedwe pakati olimba ndi madzi.

The cavitation zotsatira mu akupanga madzi akhoza kudula ndi kuwononga dendrites, zimakhudza solidification kutsogolo, kuonjezera zotsatira za yogwira mtima ndi mayamwidwe, ndi kuyeretsa dongosolo, yeretsani njere ndi homogenize dongosolo.

Kuwonjezera mawotchi kuwonongeka kwa dendrites chifukwa cha kugwedera, ina yofunika ntchito akupanga kugwedera solidification ndi kusintha ogwira undercooling wa madzi zitsulo ndi kuchepetsa yovuta phata utali wozungulira, kuti kuonjezera nucleation mlingo ndi yeretsani mbewu.

3. Kupititsa patsogolo slab khalidwe: akupanga zitsulo Sungunulani mankhwala zipangizo akhoza kuchita pa nkhungu kusintha pamwamba khalidwe la slab.Kugwedezeka kwa nkhungu ndi akupanga kungagwiritsidwe ntchito pa billet, pachimake ndi slab, ndipo palibe kutsetsereka koyipa pamene akupanga kugwedezeka ntchito.Pamene akuponya billet ndi pachimake, kwambiri yosalala billet pamwamba akhoza analandira pambuyo kutsatira akupanga kugwedera kwa nkhungu.
