Manganese Additive Kwa Aluminium Alloy Casting

2. Gwiritsani ntchito zinthu:

2.1Kutentha kowonjezera:> 730°C.

2.2 Mlingo wamankhwala wamtunduwu umawerengedwa motsatira njira iyi:

Zindikirani: Chifukwa cha kusiyana pakati pa wogwiritsa ntchito ndi zitsulo zazitsulo mu ng'anjo, zokolola zenizeni ndi kuchuluka kwenikweni kowonjezera ziyenera kuwerengedwa ndikutsimikiziridwa potengera deta yoyesa isanafike.ng'anjo.

2.3 Njira yowonjezera:

Mukasungunuka mu ng'anjo, gwedezani mofanana, tengani chitsanzo ndikusanthula kuti muwerenge kuchuluka kwa manganese wothandizira.Pamene kutentha kosungunuka kwafika, chotsani zinyalala pamwamba pa sungunulo, ndi kumwaza mankhwalawo mumbali zosiyanasiyanaa dziwe losungunuka (ngati zitsulo ndi zitsulo zamkuwa ziyenera kuwonjezeredwa, zikhoza kuwonjezeredwa nthawi imodzi).Zitatha, imirirani kwa mphindi zisanu;kusonkhezera kwathunthu, ndiye kuyimiriranso kwa mphindi 20-30;Sungunulani kwathunthu, tengani zitsanzo kuti muwunike, ndiyeno tumizani ku ndondomeko yotsatira ngati zosakanizazo zili zoyenera.

3. Kuyika ndi kusunga

20kg-25kg / bokosi, filimu ya pulasitiki kapena ma aluminium zojambulazo, zimalepheretsa chinyezi, chifukwa ufa wachitsulo womwe uli muzowonjezera umakhala wokangalika komanso wosavuta kutulutsa oxidize, ndipo kutuluka kwake kumakhala kosavuta kukhala konyowa, pamwamba pa chowonjezeracho ndi oxidized pambuyo ponyowa. , ndipo zikavuta kwambiri, padzakhala kung'ambika, komwe kungakhudze zokolola zenizeni, kapena ngakhale kusavomerezeka.

4. Moyo wa alumali

Miyezi isanu ndi itatu, angagwiritse ntchito mwachindunji mutatsegula bokosi.
