Chii chishandiso aluminium nyungudika chinoshandiswa?

Ultrassic Metal Melt Zvishandiso Zvinoshandisa Kugadziriswa Kwekuti multrasound muTrust Zviyo zvidiki uye nzvimbo yakakura muganho inogona kudzivirira kubvumidza dislocation uye intercrystalline slip, zvinoreva kuti zvinotora simba rakawanda kutyora zvinyorwa. Iye anokakavara zviyo, zvidiki zvinopararira, yakakwira simba rinoburitsa, uye zviri nani kuomarara. Iyo yakakodzera ingot chimiro ndeye yunifomu uye yakanaka yakaenzana crystal muchikamu chevhu rese chemuganda. Izvi zvinodaro nekuti crystal yekristaro ine diki anisotropy, gadziriro yunifomu panguva yekugadzirisa, kuita kwakanaka, kupokana kwakanaka, uye kunoenderana nekukanda uye kutevera purasitiki. Kuti uwane chimiro ichi, nzira yakanakisa iripo ndeyekushandisa ultrasonic simbi yekunyungudza michina yekuita kuti ishandiswe.

Ultrasonic kurapwa kwealuminium melts maitiro anoshandiswa kunatsa microcenture yesimbi nekushandisa yakakwira - mafungu enzwi. Iyi nzira inonyanya kubatsira mune iyo aluminium kukanda indasitiri yezvikonzero zvinoverengeka:

1. Degassing: eltrasonic mafungu anobatsira mukukasira aluminium nekusimudzira kusunungurwa kwemagasi akanyungudutswa senge hydrogen uye oxides. Izvi zvinovandudza midziyo yemuchina yeiyo yekupedzisira castings.

2. Zviyo zvekunatswa: Iko kushandiswa kweiyo ultrasonic vibrations inogona kuunza zviyo zvekunatswa mune yakasvibiswa simbi. Zvidiki zvidiki zveshuwa zvinotungamira kune zvakavandudzika zvine simba simba uye zviri nani pamusoro pekupedzisa zvikamu zvekukanda.

3. Homogenizization: Inobatsira mukuzadzisa kugoverwa kwunifomu yezvakarairwa zvinhu uye tembiricha mumanyunguduke. Izvi zvinoguma zvaitika pazvinhu zvinowanzoitika kumhirizhonga.

4. Yakadzora Porosity: Nekuputsa mafirimu efaira uye gasi mabhuruku, kurapa kwegasi kunodzora kuvapo kweiyo aluminium, iyo inosimudzira kutendeka kwemidziyo.

5. Kuvandudzwa Kwekupararira

Zvakawanda, Ultrasonic kurapwa kweAluminium maitiro ayo anobatsira kuti abude kumusoro - Hukuru aluminium castings neakavandudzwa mechanics zvivakwa uye kupera kwemvura.
