DESCRIPTION:
Ultrasonic zviyo zvekunatsa michinaBasa guru mukugadzirwa kwealuminium yakanyungudutswa ndeiyi: kunatsa zviyo zvesimbi, homogenizing alloy kuumbwa, kuvandudza zvakanyanya simba uye kuneta kuramba kwezvinhu zvekukanda, kuvandudza huwandu hwezvinhu zvezvinhu, kuderedza kushandiswa kwezviyo zvinonatsa uye kuderedza mari.

1. Ultrasonic kubatanidzwa kubvisa

Zvakaoma zvikuru kuti simbi mhinduro kuyangarara pamusoro diki inclusions.Padzinoungana chete ndipo padzinokwanisa kuyangarara mudenga.Kana ultrasonic kurapwa kwealuminium mhinduro, madiki inclusions anogona kuve akaturikidzana uye akaunganidzwa.Nechekuchenesa zviyo, mahombe particles anosanganisirwa anoyangarara kumusoro kuti abvise tsvina.

2. Ultrasonic degassing

kana iyo elastic vibration inounzwa musimbi yakanyungudutswa, cavitation phenomenon inowanikwa, iyo inokonzerwa negomba rinogadzirwa mushure mekuenderera kwechikamu chemvura chaputsika, saka gasi rakanyungudika musimbi yemvura rinotarisa kune dzimwe nzvimbo.Nekuda kweiyo elastic vibration ye ultrasonic, iyo bubble core inogadzirwa uye inokura ichienderera kusvika yave kuburitswa kubva musimbi yakanyungudutswa.

3. Mhedzisiro ye ultrasonic wave pane kunaka kwekukanda embryo

Kana iyo ultrasonic vibration solidification nzira inoshandiswa kugadzira castings, iyo ultrasonic wave inoburitsa iyo inotsinhanisa ruzha kudzvanywa kwebhena uye kugadzira jeti.Nekuda kweiyo nonlinear mhedzisiro, vatinoshanda navo vanoburitsa ruzha kuyerera uye micro ruzha kuyerera, nepo iyo ultrasonic hurukuro isina chinhu inoburitsa yakakwira-kumhanya jet painterface pakati pezvakasimba uye mvura.Zvese izvi zvinokonzeresa zvinogona kucheka nekuparadza dendrites, Chero kupi kune inonzwika ndima mukati memvura, inoita basa.Uchishandisa iyo cavitation mhedzisiro mune iyi maitiro, inogona kuchenesa chimiro, kunatsa zvimedu uye homogenize chimiro.Mukuwedzera kune iyo mechanical effect inokonzerwa nekudengenyeka kuparadza dendrites, rimwe basa rinokosha re ultrasonic vibration solidification nderekuvandudza kushanda kwepamusoro-soro yesimbi yemvura.Iyo yakakosha nucleus radius yakaderedzwa.Nokudaro, iyo nucleation rate inowedzera uye zviyo zvinonatswa.
