Zosefera za Ceramic Foam Refractory For Aluminium Casting

Malangizo:
Yang'anani ndikuyeretsa zinyalala pamwamba pa bokosi la fyuluta kuti bokosi la fyuluta likhale loyera komanso lopanda kuwonongeka,fufuzani chitetezo cha chida chilichonse pamzere wopanga, kuphatikizang'anjo, ochapa, zosefera mabokosi ndimakina otentha otentha pamwamba.

Pang'ono ndi pang'ono ikani mbale yosefera mubokosi losefera, ndikusindikiza chosindikizira chosindikizira ndi dzanja kuti madzi a aluminiyamu asadutse kapena kuyandama.

Preheat bokosi losefera ndi mbale zosefera mofanana kuti zikhale pafupi ndi kutentha kwa aluminiyamu yosungunuka, ndipo kutentha kwa preheating kwa mbale ya fyuluta sikutsika kuposa260 ℃.Kutenthetsa kuti muchotse madzi adsorbed kumathandiza kuti mutsegule kukula kwa pore ya fyuluta nthawi yomweyo, kupewa kutsekeka pang'ono kwa mbale yosefera chifukwa chakukula kwamafuta ndi kutsika.Magetsi kapena gasiKutentha kungagwiritsidwe ntchito poyambitsa kutentha, ndipo kutentha kwabwino kumatenga mphindi 15-30.

Pambuyo pa aluminiyumu yosungunuka kutuluka mu bokosi la fyuluta, imadutsa chochapa kupita ku pulatifomu yotsatira yoponyera.Panthawi imeneyi, tcherani khutu ku kusintha kwa aluminiyumu hydraulic mutu, ndikukhalabe kufunikira kwabwino kwa kayendedwe ka aluminium.Yabwinobwino koyambirira kukakamiza mutu ndi100-150 mm.Pamene aluminiyamu yosungunuka iyamba kudutsa, mutu wopanikizika umatsika pansi75-100 mm, ndiyeno mutu wopanikizika udzawonjezeka pang'onopang'ono.

Panthawi ya kusefa kwabwinobwino,pewani kugogodandikugwedeza mbale yosefera.Pa nthawi yomweyo, chochapa ayenera kukhalawodzazidwa ndi aluminiyamumadzi kuti apewe kusokoneza kwambiri kwa aluminiyumu yamadzimadzi.
Pambuyo kusefa, chotsani mbale yosefera mu nthawi ndikuyeretsa bokosi losefera.
