Chowonjezera chachitsulo cha aluminium alloy casting

2. Gwiritsani ntchito zinthu:

2.1 Kuwonjezera kutentha:> 750 ° C.

2.2 Mlingo wamankhwala wamtunduwu umawerengedwa motsatira njira iyi:

Zindikirani: Chifukwa cha kusiyana pakati pa ogwiritsa ntchito ndi mikhalidwe yazitsulo mu ng'anjo, zokolola zenizeni ndi kuchuluka kwenikweni kowonjezera ziyenera kuwerengedwa ndikutsimikiziridwa potengera zomwe zayesedwa zisanachitike.ng'anjo.

2.3 Njira yowonjezera

Mlanduwo ukasungunuka, gwedezani mofanana, tengani chitsanzo ndikusanthula kuti muwerenge kuchuluka kwachitsulo chomwe chawonjezeredwa.Pamene kutentha kwasungunuka kukufika, chotsani phulusa pamwamba pa kusungunuka, ndikumwaza mankhwalawa m'madera osiyanasiyana a dziwe losungunuka (ngati kuli kofunikira kuwonjezera manganese ndi mkuwa wothandizira, akhoza kuwonjezeredwa nthawi yomweyo).

Zitatha, imirirani kwa mphindi zisanu;kusonkhezera kwathunthu, ndiye kuyimirira kwa mphindi 20-30;Sungunulani kwathunthu, tengani zitsanzo kuti muwunike, ndiyeno tumizani ku ndondomeko yotsatira ngati zosakanizazo zili zoyenera.

3. Kuyika ndi kusunga:

Izi ndi zozungulira keke woboola pakati mdima imvi mtanda, ma CD mkati ndithumba la vacuum/zitsulo za aluminiyumukuyika,250g / chipika, 1kg/chikwama, ndipo zoyikapo zakunja ndi makatoni,20kg / bokosi.Kusunga mu mpweya wokwanira ndi malo ouma, kutali ndi chinyezi.

4. Moyo wa alumali

Miyezi isanu ndi itatu, angagwiritse ntchito mwachindunji mutatsegula bokosi.
